The failure pattern was observed and classified as either favorable (allowing repair) or unfavorable (not allowing repair). Adequate patient satisfaction with conventional complete dentures can be significantly increased after frenectomy. Maximum jaw opening averaged 51.2 mm which was 3.0 times larger than maximal hinge opening of 17.2 mm. Then the histological analyses were done. Significant increase in tensile bonding strength with Silfix-Aquasil and VPS Tray adhesive-Imprint II combination until 10 and 15 minutes respectively. The Journal of Prosthodontics promotes the advanced study and practice of prosthodontics, implant, esthetic and reconstructive dentistry. 8-9. Ninety freshly extracted human molars were prepared with flat occlusal surface, 6 degree taper and approximately 4 mm axial length. Degradation potential of bulk versus incrementally applied and indirect composites: color, microhardness, and surface deterioration. Every specimen of G3, G5, IR3 and IR5 was fractured on the solder joint area. J Esthet Restor Dent 2016;28:247–261. Correct occlusal relationships are part of the successful prosthetic treatment for edentulous patients. The journal promotes the advanced study and practice of prosthodontics, implant, esthetic and reconstructive dentistry. The specimens were divided into 8 groups based on the experimental conditions (cement type: Rely X UniCem or Panavia F 2.0, cement thickness: 40 or 160 µm, storage: thermocycled or not). While other HPV-infected lesions such as squamous papilloma, verruca vulgaris, and condyloma acuminatum involve the skin, oral mucosa, and genital mucosa, FEH occurs only in the oral mucosa. There were different patterns of bone regeneration between the SF membrane and the Bio-Gide® samples. The specimens were divided into three groups according to the dual-cure resin cement used: (1) Calibra silane+Calibra®, (2) Monobond S+Multilink® N and (3) ESPN sil+RelyX™ Unicem Clicker. The effect of angulation on the accuracy of these 3 techniques was also evaluated. Information regarding tooth ratio in the Korean population may be useful to clinicians when restoring anterior teeth. Then, the difference in the distance between the master cast and the experimental cast were measured, and the error rate was determined. Color differences among ceramic specimens were measured using a spectrophotometer (VITA Easyshade, VITA Zahnfabrik, Bad Säckingen, Germany) and data were expressed in CIELAB system coordinates. Of the 130 participants, 110 participants completed the prosthetic restoration procedure, but only 93 of these were able to use the prosthesis over the two-month period. 2 mm, 3 mm and 4 mm polyoxymethylene, does not bring about significant change in stress distribution pattern and displacement as compared to 3 mm Ti abutment. Data were analyzed statistically using the Independent t-test at 5% statistical significance level. In non-thermal aged groups, SBS of Multilink group (M1) was higher than that of Calibra (C1) and Unicem (U1) group (P<.05). To compare the accuracy of marginal and internal adaptation of zirconia (Zr) copings fabricated on anatomic (A), semi-anatomic (SA) and non-anatomic (NA) occlusal surface preparations. The ISQ values were showed increased tendency after 5 weeks in every groups. In NON-MEDIA group, however, there were significant differences between female and male. In this experiment, Multilink showed the highest SBS before and after thermocycling. This article describes a modified technique to fabricate the soft tissue cast for the conventional fixed partial denture. This variation may be associated with the lack of standardization of the preparation of teeth, computerized designing of the coping for each tooth, cement used, uniform pressure application during the cementation of the copings, sectioning of the copings and the microscopic measurements. The initial stability was much affected by the implant design in bone types III, IV and the implant design such as the short pitch interval was beneficial to the initial stability of implants placed above the bone level. Cell culture was performed at 4, 8, 12 and 16 days. A device was used to standardize seating of copings on the metal die and positioning of the specimens under the microscope after each stage of fabrication. We aimed to identify a more esthetic width-to-length ratio by analyzing maxillary central incisor of Korean adult population. Each group of 24 samples was subdivided at 2, 4, and 8 weeks after implantation. A static loading test was carried out and loads were applied to the buccal surface of the buccal cusp at a 45 degree inclination to the long axis of the tooth until failure occurred. J Calif Dent Assoc 2009;37:389–398. Thirty disc-shaped cores, 12 mm in diameter with a 1 mm thickness were fabricated from zirconium oxide based all ceramic systems (Lava™, 3M ESPE, St Paul, MN, USA) and divided into three groups (n = 10) according to veneering with dentin ceramic thicknesses: as 0.5, 1, or 1.5 mm. The statistically efficient drying time was evaluated through ANOVA and Scheffe test. The mean VHN values of the resins light cured for 40 seconds were significantly higher than that of LED for 20 seconds in all four resin materials (P<.05). This study is to investigate an appropriate drying time of tray adhesives by evaluating tensile bonding strength between two types of polyvinylsiloxane impression materials and resin tray, according to various drying time intervals of tray adhesives, and with different manufacturing company combination of impression material and tray adhesive. The values were analyzed to determine the difference between the mean ISQ values of Osstell™ and Osstell™ Mentor. Within the limitations of this study, the pick-up type impression coping exhibited a more accurate implant master cast than the transfer type in parallel group. All the tests were performed at 95% confidence level. The aim of this study was to evaluate the effect of dimensional stability of splinting material on the accuracy of master casts. The stress distribution pattern and displacement at the junction of cortical bone and implant was recorded. In ISQ values, The lowest stability was observed at different times for each individual. Vicker's microhardness numbers (VHNs) were measured on the bottom surfaces by a microhardness tester. These values were statistically analyzed. The specimens were stored in water at 25℃ for 24 hours, and then evaluated for their shear bond strength by universal testing machine (STM-5®, United Calibration, USA). However, there were no significant differences in fracture strength between the groups. All specimens were stored in distilled water at room temperature for 24 hrs and provisional cements were mechanically removed with explorer and rinsed with water and cleansed using various methods (Control-air-water spray, Pumice prophylaxis, Ultrasonic scaler with 0.2% Chlorhexidine gluconate, 17% EDTA). Shear strength was measured using a universal testing machine at a speed of 5 mm/min and evaluated of fracture using an optical microscope. Group 1 showed the maximum and Group 5 showed the least value. Anatomical occlusal preparation designs resulted in better marginal and internal adaptation of Zr copings. Fasbinder DJ, Neiva GF. The Zr copings were fabricated by using CAD4DENT, CAD/CAM. Clinically, with the application of resilient material abutment there is no significant change in stress distribution around implant-bone interface. A repeated measures ANOVA and Bonferroni post hoc test were used to analyze the data (n = 10, α=.05). Cementing agents used were zinc phosphate, glass ionomer and resin modified glass ionomer cement. A stainless steel metal model with 6 implants embedded was used as a master model. J Adv Prosthodont. In group LCT, the glass fiber post (LuxaPost) cementation and core foundation was accomplished with composite resin (LuxaCore-Dual) in separated procedures. Effects of surface conditioning on repair bond strengths of non-aged and aged microhybrid, nanohybrid, and nanofilled composite resins. Specimens without the primer were also prepared and used as the controls. A vertical load of 11 N was applied with a frequency of 2 cycles/sec. A 3D Finite Element Analysis of Bone Tissue in 3-Unit Implant-Supported Prostheses: Effect of Splinting Factor and Implant Length and Diameter This clinical report presents the clinical appearance and treatment approach in a case of excessive anterior teeth erosion resulted from swimming in a poorly-chlorinated swimming pool. The most unfavorable width-height ratio was noted for the group, which was comprised of the second molar in the multiple adjacent (first and second molar) implant-supported restorations. One way ANOVA and Tukey HSD post hoc tests were performed to analyze the data obtained (P < .05). The mean fracture strength was highest in group DCT followed in descending order by groups DMO, DMT, and LCT. Tekçe N, Pala K, Demirci M, Tuncer S.

Measurements recorded at 9 predetermined points showed variations for the three groups. The present study was intended to evaluate the effect of soldering techniques with infrared ray and gas torch under different gap distances (0.3 mm and 0.5 mm) on the tensile strength and surface porosity formation in Ni-Cr base metal alloy. All three cements showed lower SBS after the thermocycling than before the treatments. 130 participants who required removable prosthesis were surveyed with a standard form that included questions regarding age, gender, education level, dental attendance, and prosthetic restoration type. After recording of sample sounds, speech intelligibility tests by three speech pathologists and acoustic analyses were performed. The Ti-Ta-Nb disks and its sputtered nanoscale coatings exhibited greater hydrophilicity and rougher surfaces compared to the Ti-6Al-4V disks. Title D.O.I. After 6 months of function, silicone impressions were taken and stone models were fabricated for each restoration group. 3. Thermocycled groups showed lower microtensile bond strength than non-thermocycled groups (P<.001). In this study, the difference in the stability of the implants was determined not by the differences in the surface treatment but by the individual specificity. The angle between orbitale and ala-tragus averaged 13.6 degrees. This study compared the bond strength of porcelain to millingable palladium-silver (Pd-Ag) alloy, with that of 3 conventionally used metal-ceramic alloys.

This journal aims to convey scientific and clinical progress in the field of prosthodontics and its related areas to many dental communities concerned with esthetic and functional restorations, occlusion, implants, prostheses, and biomaterials related to prosthodontics. This study was aimed to evaluate the relationship between width and height of buccal soft tissue around single and 2 adjacent implant restorations. Individual crowns with loop were made from base metal alloy. Microbial growth was verified at 24 hrs and 72 hrs and the antimicrobial effects of samples were evaluated as a percentage of viable cells in withdrawn suspension (100 µL). Resin-composite blocks for dental CAD/CAM applications. Twenty men and women were served as subjects in the present study. Specimens were cemented with Variolink® II resin cement. This study evaluated marginal fit of glass infiltrated alumina cores fabricated using two techniques and their marginal stability after firing cycles of veneering porcelain. An ala-tragus line and an occlusal line were drawn on the left side of the face to determine if these two lines were parallel. Every metal-ceramic alloy used in this study showed clinically applicable bond strength with porcelain (25 MPa). The thickness of ceramic disc increased, the VHNs of all four resin types were decreased (P<.05). The following data were collected from the dental records and radiographs: patient's age, gender, implant type and surface, length, diameter, location of implant placement, bone quality, prosthesis type. However, recently, due to the continuous rise in the price of gold, an interest towards materials to replace gold alloy is getting higher.

Within the limitation of this in vitro study, the results suggest that the tissue conditioner containing silver nanoparticles could be an antimicrobial dental material in denture plaque control. Polishing methods of an alumina-reinforced feldspar ceramic. The shear bond strengths were measured on a screw-driven universal testing machine. The type of metal-ceramic alloys affects the bond strength of porcelain. The aim of this retrospective study is to analyze the relationship between local factors and survival rate of dental implant which had been installed and restored in Seoul Veterans Hospital dental center for past 10 years. After firing of veneering porcelain the difference was insignificant. The Journal of Prosthetic Dentistry is the leading professional journal devoted exclusively to prosthetic and restorative dentistry.The Journal is the official publication for 24 leading U.S. international prosthodontic organizations. Additionally, no significant difference was observed between the parallel and mesial angulated groups. Prosthodontics is the area of dentistry that focuses on dental prostheses. The closed tray and the resin-splinted open tray technique showed significantly different vertical gaps according to the angulation of implant (P < .05), but the A-F impression technique did not (P > .05). Education level and prosthesis type did not significantly influence the GPA-pa SF score at any time point analysed (P>.05). Experimental disc samples (20.0×3.0 mm) of tissue conditioner (GC Soft-Liner, GC cooperation, Tokyo, Japan) containing 0.1 - 3.0% silver nanoparticles (0%: control) were fabricated. Five vertical and six horizontal distances were measured on each subject's face. Desensitizing agents were applied before cementation of crowns except for control group. The distortion values of each splinting methods were measured using coordinate measuring machine, capable of recordings in the x-, y-, z-axes. PURPOSE Acar B, Egilmez F.

The statistical assessment was carried out using SPSS V. 12.0 for Win. The number of firings and dentin ceramic thickness have a definite effect on the final color of all ceramic system tested. Statistical analysis was performed with the use of Kaplan-Meier analysis, Chi-square test and odds ratio. In the first stage, the mean ISQ value for Osstell™ and Osstell™ Mentor was 70.84 and 75.09, respectively, showing a significant difference (P < .01). (1) Splinted with autopolymerizing resin and sectioned, reconnected to compensate polymerization shrinkage before the impression procedure. The proportions of porosity on the fractured surface were calculated on the images acquired through the scanning electronic microscope. The use of appropriate adhesive metal primers makes it possible not only to eliminate the need for surface preparation of the metal framework before applying the heat cure resins, but also reduce the need for retentive devices on the metal substructure. Also, bond strengths of all three cements decreased after thermocycling. Dent Mater 2007;23:893–899. A study on the changes in attractive force of magnetic attachments for overdenture Han-Wool Leem, In-Ho Cho, Jong-Hyuk Lee and Yu-Sung Choi: Department of Prosthodontics, College of Dentistry, Dankook University, Cheonan, Republic of Korea. 4 nano-treated surface implants (20 nm TiO(2) coating surface, heat-treated 80 nm TiO(2) coating surface, CaP coating surface, heat treated CaP coating surface) and 3 micro-treated surface implants [resorbable blast media (RBM) surface, sandblast and acid-etched (SAE) surface, anodized RBM surface] were used as experiment groups. Significant interactions were present in L*a*b* values between the number of firings and ceramic thickness (P<.001). The MEDIA group consisted of 40 celebrities selected only on the basis of their soft-tissue facial appearance. J Adv Prosthodont. Hampe R, Lümkemann N, Sener B, Stawarczyk B. The need for the soft tissue cast is quite evident as the soft tissue emergence profile that surrounds the prepared tooth is destroyed in the process of fabrication. Silk fibroin (SF) is a new degradable barrier membrane for guided bone regeneration (GBR) that can reduce the risk of pathogen transmission and the high costs associated with the use of collagen membranes. In type II bone, the decrease in ISQ value per 1-mm increase in effective implant length of the Brånemark and Astra implants was less than that of the Straumann implant.

Light-post) cementation and core foundation; in group DMO, these procedures were performed simultaneously in one step, while DMT group was accomplished in separated two steps. Light-post) was cemented with resin cement (DUO-LINK) and a core foundation was formed with composite resin (LIGHT-CORE). And when the relationship is found out, it could be helpful to predict the prognosis of dental implants. The mean GPA-pa SF score obtained at T0 was higher than the scores obtained at the other periods in the total of the sample. Mechanical fatigue degradation of ceramics versus resin composites for dental restorations. Maxillary labial and buccal frena are considered as normal anatomic structures in the oral cavity. Bone regeneration was observed in the SF and Bio-Gide®-treated groups to a greater extent than in the control group (mean volume of new bone was 5.49 ± 1.48 mm(3) at 8 weeks). It was concluded that nanoscale Ti-Ta-Nb coatings enhance cell adhesion. We aim to find the clinical significance of surface treatments by observing the differences in the stabilization stages of implant stability. The purpose of this study was to compare the accuracy of the implant master cast according to the type (pick-up, transfer) and the length (long, short) of the impression copings. Vasudeva G. Monomer systems for dental composites and their future: a review. In bone types III and IV, this value in the Astra implant was less than that in the other 2 implants. The simplicity of this technique facilitates and justifies its routine use in fabrication of the fixed partial denture. The metal copings with five different metal framework designs were designed from Group 1 to 5. Within the limitations of this study, all methods of surface treatment used in this study are clinically available. The copings were adjusted, cemented and were cross sectioned centrally from buccal cusp tip to lingual cusp tip into mesial and distal halves. And porcelain was applied on the center area of metal specimen. Data were recorded as the mean of three colony forming unit (CFU) numerations and the borderline of the antimicrobial effect was determined at 0.1% viable cells. Provisional restorations made with autopolymerizing resin were luted to dentin surface with zinc oxide eugenol in Group A and with freegenol cement in Group B. In the control group, there was a significant difference in the ISQ values of the 3 implants in bone types III and IV (P<.05). Model 1: Implant with 3 mm titanium abutment, Model 2: Implant with 2 mm polyoxymethylene resilient material abutment, Model 3: Implant with 3 mm polyoxymethylene resilient material abutment and Model 4: Implant with 4 mm polyoxymethylene resilient material abutment. The accuracy of the A-F impression technique was superior to that of conventional techniques, and was not affected by the angulation of the implants. The latter method is more feasible because the mobility of denture base on the mucosa in oral cavity does not permit the identification of premature contacts in centric occlusion and tooth guided eccentric excursions. It is published by The Korean Academy of prosthodontics. As a control group, 7 specimens were prepared without sectioning or soldering. However, there is a lack of information on how color is affected by fabrication procedure. Dent Mater 2008;24:522–529. This technique does not require additional clinical appointment, second impression procedure, technique sensitive manipulations with impression, or cumbersome laboratory procedures. (5) Splinted with VPS bite registration material. As the dentin ceramic thickness increased, significant reductions in L* values (P<.01) were recorded. The ala width and distance between the tips of upper right and left canine cusps averaged (35.2 mm and 34.8 mm) but with very large individual variations. Four kinds of resin materials were used. Chemical disinfection with sodium hypochlorite seems to be a safer method of disinfection with regards to physical properties such as changes in dimensional stability. Bond strength of IDS/SE group had a significantly higher mean than DDS group (3.14 MPa) (P < .05). Four types of impression coping were prepared with different combinations of types (transfer, pick-up) and lengths (long, short) of the coping. The influence of the modified process in the fiber-reinforced post and resin core foundation treatment on the fracture resistance and failure pattern of premolar was tested in this study. Significant difference was present between mean scores obtained at T0-T1 and T2-T3 than scores obtained at other periods (P<.05). They were used combinations from the same manufacture and exchanged combinations of the two. The affected region resembles the normal color of oral mucosa rather than appearing as a white color since the epithelial surface is not hyperkeratinized. However, further studies are needed on the correlation between speech intelligibility tests and objective acoustic parameters. Geneva; Switzerland: International Standards Organization (ISO); 2009. Resin modified glass ionomer cement exhibited the highest retentive strength and all dentin treatments resulted in significantly different retentive values (In Kg. Does artificial aging affect mechanical properties of CAD/CAM composite materials. Nonprecious Ni-Cr alloy and precious metal alloy containing 32% of gold showed significant difference (P<.05). The open tray techniques showed significantly smaller vertical gaps compare to closed tray technique (P < .05). Additionally, the accuracy of the implant cast was not different for the parallel and 10° mesial angulated groups. No significant gender differences were found in the width-to-length ratio in MEDIA group. (SPSS Inc., Chicago, USA). Monomers used in resin composites: degree of conversion, mechanical properties and water sorption/solubility. Recent to Old .

VPS Tray Adhesive-Imprint II had a superior tensile bonding strength when compared to Silfix-Aquasil over 15 minutes. The mean ratio for the MEDIA group was 0.77, whereas that of the NON-MEDIA group was 0.88. In addition, the correlations between the speech intelligibility values and acoustic variables were analyzed. Watanabe T, Miyazaki M, Takamizawa T, Kurokawa H, Rikuta A, Ando S. Influence of polishing duration on surface roughness of resin composites. The sputtered Ti-Ta-Nb coatings consisted of dense nanoscale grains in the range of 30 to 100 nm with alpha-Ti crystal structure. The maximum load required to fracture the test specimens even in the groups without the metal collar was found to be exceeding the occlusal forces. Data were statistically analyzed by one-way analysis of variance with Tukey HSD tests (α=.05). In PTV, all implants were stabilized except 1 failed implants. GPA-pa SF scores were higher before the restoration procedure began, and decreased over time with the use of prosthesis. Ceramics have a long history in fixed prosthodontics for achieving optimal esthetics and various materials have been used to improve ceramic core strength.

The effect of artificial aging on Martens hardness and indentation modulus of different dental CAD/CAM restorative materials. Related factors such as age, implant type, length, location and prosthesis type had a significant effect on the implant survival. Cell attachment was measured using coulter counter and the cell morphology during attachment period was observed using fluorescent microscopy. A 0.1% silver nanoparticles combined to tissue conditioner displayed minimal bactericidal effect against Staphylococcus aureus and Streptococcus mutans strains, a 0.5% for fungal strain. To achieve a favorable level of buccal gingival margin, greater thickness of buccal supra-implant mucosa is required for the implant restorations without a neighboring natural tooth compared to the implant restorations next to a natural tooth. Group 2 and 5 showed relatively larger distortion value than other groups. Repeated firings (3, 5, 7, or 9) were performed, and the color of the specimens was compared with the color after the initial firing. The objective of the present study was to evaluate the effect of five different metal framework designs on the fracture resistance of the metal-ceramic restorations. The Journal of Advanced Prosthodontics ☰ Vol. The difference between the two groups was statistically significant. The analysis of variance was performed using the SPSS (v 12.0) program (α = .05), and the statistical significance was set at P < .05. Errors occurring during the clinical and laboratory procedures of a denture may subsequently lead to the occlusal errors in the final prosthesis. A few of studies which compared and continuously measured the stability of various surface treated implants in the same individual had been performed. Further mechanical stability and toxicity studies are still required. Data was statistically analyzed by one-way analysis of variance in confidence level of 95%.

The use of a catalyst produced a greater hardness with all polymerization methods. There were significant increases in both a* and b* values (P<.01) as the dentin ceramic thickness increased. Access this journal on ScienceDirect. Statistical analysis included one-way ANOVA followed by Turkey-Kramer post hoc test at a preset alpha of 0.05. For calculation of dimensional changes in denture bases, differences between the baseline area before and after disinfection of the specimens were used. To compare the effect of sodium hypochlorite and microwave disinfection on the dimensional stability of denture bases without and with relining. The aim of this study was to find out correlation between the ISQ values acquired from Osstell™ and Osstell™ Mentor, and to evaluate the clinical effectiveness and accuracy of two devices. The specimens were not cemented and marginal gap was measured using an image analyzing software (Imagepro Express) on the photographs captured under an optical microscope.

Alshali RZ, Salim NA, Satterthwaite JD, Silikas N. Long-term sorption and solubility of bulk-fill and conventional resincomposites in water and artificial saliva. Dent Mater J 2013;32:107–114. There were no significance in the mean shear bond strength between IDS/SB (4.11 MPa) and DDS group. EDTA was the most effective dentin cleansing agent among the compared groups. Clinical findings revealed tooth sensitivity, severe enamel erosion resembling veneer preparations, and the presence of anterior open bite. Rodrigues SA Jr, Ferracane JL, Della Bona A. Flexural strength and Weibull analysis of a microhybrid and a nanofill composite evaluated by 3- and 4-point bending tests. From master model, 5 impressions and 5 experimental casts, total 25 casts were made for each of 5 splinting methods. However, the absolute volume of new bone in the SF membrane-treated group was not significantly different from that in the collagen membrane-treated group at 8 weeks (8.75 ± 0.80 vs. 8.47 ± 0.75 mm(3), respectively, P=.592). Differences in cement thickness did not influence the resin-zirconia microtensile bond strength given the same resin cement or storage conditions (P>.05). Many dentists use desensitizing agents to prevent hypersensitivity. The porcelain fused to gold has been widely used as a restoration both with the natural esthetics of the porcelain and durability and marginal fit of metal casting. 私たちと共有してください！. The changes in dimensional stability after sodium hypochlorite disinfection were not significant for both denture bases without relining (t = 2.19; P=.056) and denture bases with relining (t = 2.17; P=.058). The drying time was designed to air dry, 5 minutes, 10 minutes, 15 minutes, 20 minutes, and 25 minutes. Two dimensional finite element models of cylinderical implant, abutments and bone made by titanium or polyoxymethylene were simulated with the aid of Marc/Mentat software. No cohesive failure was observed in any experimental group. Within the limitations of this study, it was concluded that both techniques produced copings with comparable and acceptable marginal fit and marginal stability on firing veneering porcelain. Am J Dent 2018;31:91–96. For the purpose of this study, the central incisor tooth was prepared, and the metal analogue of it and a master die were fabricated. In the histological findings, the bone formation was observed to be adequate in general and no differences among the 8 surface treated implants. The affected oral mucosa exhibits multiple papules and nodules with each papule/nodule being flat-topped or sessile. However, the specimens primed with the Alloy primer® (MDP monomer) showed higher bond strength than those primed with the MR bond® (MAC-10 monomer) on titanium. They were cured through ceramic discs (IPS e.max Press MO-0 ingot ivoclar vivadent, 10 mm diameter, 0.5, 1 and 2 mm thicknesses) by LED light-curing units for 20 and 40 seconds. IDS/SE (immediate dentin sealing, Clearfil™ SE Bond) and IDS/SB (immediate dentin sealing, AdapterTM Single Bond 2) were light-cured after application of dentin bonding agent (Clearfil™ SE Bond and Adapter™ Sing Bond 2, respectively), whereas DDS specimens were not treated with any dentin bonding agent. Tray adhesive-impression material combination from the same company presented higher tensile bonding strength at all drying time intervals than when using tray adhesive-impression material of different manufactures. To record the vertical gap between reference frameworks and analogs in duplicate casts, a light microscope with image processing was used. J Oral Sci 2005;47:21–25. Sixty two implants were inserted into 47 patients, and their ISQ values were measured using Osstell™ and Osstell™ Mentor. Dent Mater 2014;30:424–432. No significant differences were found in relation to the following factors: gender, diameter and bone quality (P>.05). J Mech Behav Biomed Mater 2018;86:191–198. The hybrid ceramic restorations can be recommended with no complications. Implant level impressions were made after square impression copings were splinted using 5 different techniques as follows. The purpose of this study was to determine the average facial proportions and mandibular movement capacity of 316 first-year dental students who carefully recorded them on each other. The ala-tragus line and the occlusal plane lines were for all practical purposes parallel. After retrieval of the cast, the same impression was poured second time with the resin based resilient material to cover the facial and proximal gingival areas. However there is not clear mention of drying time of tray adhesive in achieving appropriate bonding strength of tray material and impression material. Group 1 showed best accuracy followed by Group 3 & 4. The purpose of this study was to evaluate the effects of various dentin ceramic thicknesses and repeated firings on the color of zirconium oxide all-ceramic system (Lava™) fabricated using CAD/CAM technology. Periotest® & ISQ values measured for 8 weeks and all animals were sacrificed at 8 weeks after surgery. Evaluation of failure patterns indicates that most failures in the control group and IDS/SE groups were mixed, whereas failures in the DDS were interfacial. L*a*b* values of the ceramic systems were affected by the number of firings (3, 5, 7, or 9 firings) (P<.001) and ceramic thickness (0.5, 1, or 1.5 mm) (P<.001). Data were analyzed by two-way analysis of variance and the Tukey test. To find out the differences in SBS according to the types of cements and thermocycling using the SPSS, two-way ANOVA was conducted and post-hoc analysis was performed by Turkey's test. 2019 Apr;11(2):128-137. In particular, the Alloy primer®, which contains the phosphoric acid monomer, MDP, might be clinically more acceptable for bonding a heat cure resin to titanium than a MR bond®, which contains the carboxylic acid monomer, MAC-10. The aim of this study was to determine differences in shear bond strength to human dentin using immediate dentin sealing (IDS) technique compared to delayed dentin sealing (DDS). Toxicol in vitro 2010;24:854–862. https://doi.org/10.4047/jap.2019.11.2.128. The success of titanium implants is due to osseointegration or the direct contact of the implant surface and bone without a fibrous connective tissue interface. They were cut into microbeams and stored in 37℃ distilled water for 24 h. Microbeams of non-thermocycled specimens were submitted to a microtensile test, whereas those of thermocycled groups were thermally cycled for 18,000 times immediately before the microtensile test. Ti6-Al-4V alloy disks were used as controls. Copings were compared between groups and within groups at coping stage and after firing each layer of veneering porcelain. There was no significant difference in ultimate tensile strength of joints and porosity formations between the gas-oxygen torch soldering and infrared ray soldering technique or between the gap distance of 0.3 mm and 0.5 mm. In addition, Ti-Ta-Nb alloy and its nanoscale coatings enhanced osteoblast differentiation, but did not support osteoblast precursor proliferation compared to Ti-6Al-4V. The mean ΔE value increased as the dentin ceramic thicknesses increased for zirconium-oxide based all ceramic specimens tested. The Journal of Prosthodontics serves both researchers and practicing clinicians by providing a forum for the presentation and disc… Short and long term effects of additional post curing and polishing systems on the color change of dental nano-composites. For the soldering methods, gas torch (G group) and infrared ray (IR group) were compared and each group was subdivided by corresponding gap distance (0.3 mm: G3 and IR3, 0.5 mm: G5, IR5). The definition of journal acceptance rate is the percentage of all articles submitted to Journal of Advanced Prosthodontics that was accepted for publication. Oper Dent 2018;43:90–100. SEM showed that EDTA was the most effective solution to remove the smear layer. After analyzing maxillary anterior teeth of Korean adults, our results were in accordance with the general Western standards of esthetics. Specimens treated with EDTA showed the highest shear bond strength and the lowest contact angle for both groups. 11 (2019) No.6 December; No.5 October; No.4 August Microwave disinfection produces significant shrinkage in both denture bases without relining (t = 17.16; P<.001) and with relining (t = 14.9; P<.001). Four implant restoration groups (first and second molars, single second molars, posterior single restorations between teeth, and anterior single restorations between teeth) were randomly chosen from one dental institute. These occlusal errors can be corrected in two ways: i) in patient's mouth ii) by recording new centric relation and remounting dentures on an articulator. Three Implant system (Brånemark System® Mk III TiUnite™, Straumann Standard Implant SLA®, and Astra Tech Microthread™-OsseoSpeed™) were tested. The significant difference in the values obtained using the Osstell™ and Osstell™ Mentor between the first and second stages of implant surgery indicates that these values can be a convenient and precise way for evaluating the implant stability in clinical practice. Samples were placed on separate culture plate dish and microbial suspensions (100 µL) of tested strains were inoculated then incubated at 37℃. It is the official journal of the American College of Prosthodontists, the American Dental Association-recognized voice of the Specialty of Prosthodontics. Yet, the higher levels of safety, accuracy and ultimate patient benefit from advanced digital imaging suggests that time may be ripe for its introduction into prosthodontics. Academy of Advanced Prosthodontics in Taiwan (no website) American Academy of Restorative Dentistry, The ; American Equilibration Society, The ; ... Journal Information and Metrics. Oper Dent 2006;31:11–17. J Adv Prosthodont. Thirty-six human mandibular premolars were divided into 4 groups (n = 9). Thirty-two freshly extracted molars were transversely sectioned at the deep dentin level and bonded to air-abraded zirconium oxide ceramic disks. The monthly publication features timely, original peer-reviewed articles on the newest techniques, dental materials, and research findings. To evaluate the shear bond strength of resin luting agent to dentin surfaces cleansed with different agents like pumice, ultrasonic scaler with chlorhexidine gluconate, EDTA and the influence of these cleansing methods on wetting properties of the dentin by Axisymmetric drop Shape Analysis - Contact Diameter technique (ADSA-CD).
