This study evaluated marginal fit of glass infiltrated alumina cores fabricated using two techniques and their marginal stability after firing cycles of veneering porcelain. For zinc phosphate cement the retentive strength were lowest GLUMA (27.92 ± 3.20) > Control (27.69 ± 3.39) > Tooth mousse (25.27 ± 4.60). Clinically, with the application of resilient material abutment there is no significant change in stress distribution around implant-bone interface. 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. 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. Adequate patient satisfaction with conventional complete dentures can be significantly increased after frenectomy. Cementing agents used were zinc phosphate, glass ionomer and resin modified glass ionomer cement. It is the official journal of the American College of Prosthodontists, the American Dental Association-recognized voice of the Specialty of Prosthodontics. It is published by The Korean Academy of prosthodontics. The number of adhesive failures increased after thermocycling in all experimental conditions. 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. When preparing teeth for indirect ceramic restoration, IDS with Clearfil™ SE Bond results in improved shear bond strength compared with DDS. New bone formation was evaluated using microcomputerized tomography and histological examination. Forty coronal portions of human third molar were prepared until dentin was exposed. As a control group, 7 specimens were prepared without sectioning or soldering. In the second stage, the mean ISQ value of Osstell™ and Osstell™ Mentor was 71.76 and 75.94, respectively, also showing a significant difference (P < .01). The Pearson correlation coefficient was used to examine the correlation between Osstell™ and Osstell™ Mentor in the first and second stages of surgery, whereas the difference between their ISQ values was evaluated using a paired t-test. This article describes a modest and effective clinical chair-side remount procedure using customized mounting platforms. The stress distribution pattern and displacement at the junction of cortical bone and implant was recorded. This article describes a modified technique to fabricate the soft tissue cast for the conventional fixed partial denture. One way ANOVA and Tukey HSD post hoc tests were performed to analyze the data obtained (P < .05). Thirty-six human mandibular premolars were divided into 4 groups (n = 9). 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. 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. Poplawski T, Loba K, Pawlowska E, Szczepanska J, Blasiak J. Genotoxicity of urethane dimethacrylate, a tooth restoration component. Therefore, the metal frameworks with 0.5 mm and 1 mm short of the finish line are recommended for anterior metal ceramic restoration having adequate fracture resistance. Nonprecious Ni-Cr alloy and precious metal alloy containing 32% of gold showed significant difference (P<.05). But Multilink and Unicem had a significant difference (P<.05). This web edition is produced by Quintessenz Verlags-GmbH, Berlin. The poor chemical bonding of a denture base resin to cast titanium framework often introduces adhesive failure and increases microleakage. There were significant differences in age, implant type and surface, length, location and prosthesis type (P<.05). He obtained his training in advanced Prosthodontics at USC. The mean shear bond strengths of control group and IDS/SE group were not statistically different from another at 14.86 and 11.18 MPa.

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 type of metal-ceramic alloys affects the bond strength of porcelain. 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). Nanoscale Ti-Ta-Nb coatings exhibited significantly greater ALP specific activity and total protein production compared to the other 2 groups. 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. As the dentin ceramic thickness increased, significant reductions in L* values (P<.01) were recorded. American Dental Association. Dentin bonding agent (Excite® DSC) was left unpolymerized until the application of porcelain restoration. Specimens were divided into two groups: Group A and Group B. The scope of Journal of Advanced Prosthodontics covers Dentistry (miscellaneous) (Q2), Oral Surgery (Q2).

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). 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. Comparison of the speech intelligibility test scores and acoustic parameters such as fundamental frequency, fundamental frequency range, formant frequency, formant ranges, vowel working space area, and vowel dispersion were done between men and women. The acceptance rate of Journal of Advanced Prosthodontics is still under calculation. J Dent 2015;43:1511–1518. 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. The mean fracture strength was highest in group DCT followed in descending order by groups DMO, DMT, and LCT. J Adv Prosthodont. Machined surface implants were used as a control group. 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. Data were analyzed by two-way analysis of variance and the Tukey test. 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). Dent Mater 2014;30:424–432. Group 2 and 5 showed relatively larger distortion value than other groups. The analysis of variance was performed using the SPSS (v 12.0) program (α = .05), and the statistical significance was set at P < .05. 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. © 2019 The Korean Academy of Prosthodontics.

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. Prosthodontics is the area of dentistry that focuses on dental prostheses. 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. There were no significance in the mean shear bond strength between IDS/SB (4.11 MPa) and DDS group. Microwave disinfection leads to increased shrinkage of denture bases without and with relining. A retrospective study of patients receiving root-shaped screw-type dental implants placed from January 2000 to December 2009 was conducted. This study was aimed to evaluate the relationship between width and height of buccal soft tissue around single and 2 adjacent implant restorations. Short and long term effects of additional post curing and polishing systems on the color change of dental nano-composites. 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. J Mech Behav Biomed Mater 2018;86:191–198. At the final stage, both groups exhibited lower mean marginal gaps than at the initial coping stage with the difference of 11.75 µm for group A and 11.94 µm for group B, but it was statistically insignificant due to high value of standard deviation. It promotes the advanced study and practice of prosthodontics, implant, … It is the official journal of the American College of Prosthodontists, the American Dental Association-recognized voice of … A higher prevalence of favorable fractures was detected in group DMT but there were no significant differences between the groups.

Department of Biomaterials & Prosthodontics, Kyung Hee University Hospital at Gangdong, Institute of Oral Biology, School of Dentistry, Kyung Hee University, 892 Dongnam-ro, Gangdong-gu, Seoul 05278, Republic of Korea. Control group implants were placed in level with the bone, while test group implants were placed 1, 2, 3, and 4 mm above the bone level. Desensitizing agents were applied before cementation of crowns except for control group. Light-post) was cemented with resin cement (DUO-LINK) and a core foundation was formed with composite resin (LIGHT-CORE). Thinner ceramic disc with increased curing time resulted higher VHN values of all resin materials. The ANOVA showed that the pick-up type impression coping exhibited a significantly lower error rate than the transfer type. Specimens of the experimental groups were sectioned in the middle with a diamond disk and embedded in solder blocks according to the predetermined distance. Use of custom tray and tray adhesive is clinically recommended for elastomeric impression material. The width and length of the maxillary central incisor were measured using Adobe Photoshop® 7.0, a software for analysis, measurement and edition of photographs. The use of a catalyst produced a greater hardness with all polymerization methods. Little information is available about the buccal gingival level of multiple implant restorations. (3) Primary impression made with impression plaster and secondary impression were made over with polyether impression material. Three-point bending test was performed with universal testing machine. He has published in numerous peer-reviewed journals and textbooks on various topics related to Prosthodontics, Aesthetics, and Implant Dentistry. However, no significant difference was observed with respect to the length of the impression coping. Bottino MC, Valandro LF, Kantorski KZ, Bressiani JC, Bottino MA. From master model, 5 impressions and 5 experimental casts, total 25 casts were made for each of 5 splinting methods. However, they may exist intraorally as a thick broad fibrous attachment and/or become located near the crest of the residual ridge, thus interfering with proper denture border extension resulting in inferior denture stability, retention and overall patient satisfaction. All the tests were performed at 95% confidence level. After firing of veneering porcelain the difference was insignificant. This early exacting clinical experience was closely supervised by the authors in Columbus, Ohio during 1969-70. Twenty men and women were served as subjects in the present study. Oper Dent 2018;43:90–100. Dent Mater 2008;24:522–529. In addition, the correlation between implants used in the first and second stage of surgery with regard to their types and areas of insertion were analyzed. The ISQ values were showed increased tendency after 5 weeks in every groups. Group 1 showed the maximum and Group 5 showed the least value. We report a case of FEH that arose on the attached gingiva of an East Asian male adult related to prosthesis without detection of any HPV subtype in HPV DNA chip and sequencing. 12 (2020) No.5 October; No.4 August; No.3 June; No.2; Vol. There was a negative correlation between porosity formation and tensile strength in all the specimens in the test groups (P < .05). 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). Errors occurring during the clinical and laboratory procedures of a denture may subsequently lead to the occlusal errors in the final prosthesis. Measurements recorded at 9 predetermined points showed variations for the three groups. Ninety freshly extracted human molars were prepared with flat occlusal surface, 6 degree taper and approximately 4 mm axial length. The affected region resembles the normal color of oral mucosa rather than appearing as a white color since the epithelial surface is not hyperkeratinized. 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. Egilmez F, Ergun G, Cekic-Nagas I, Vallittu PK, Lassila LVJ. In group DCT, the quartz fibre post (D.T. Eventually, 40 experimental casts were produced. Further mechanical stability and toxicity studies are still required. Dr. Reshad is currently on the editorial board on various journals including the Journal of Aesthetic and Restorative Dentistry. Specimens without the primer were also prepared and used as the controls. This rare, benign epithelial proliferation is related to low-risk HPV, especially HPV-13 and -32, and is not transformed into carcinoma. Journal of Advanced Prosthodontics is a journal covering the technologies/fields/categories related to Dentistry (miscellaneous) (Q2); Oral Surgery (Q2).

A one-way analysis of variance (ANOVA) at a confidence level of 95% was used to evaluate the data and Tukey's studentized range test was used to determine significant differences between the groups. 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. 3. The marginal gap was smaller at the coping stage in group B (60 + 30 µm) than group A (81 + 21 µm) with statistical significance. However there is not clear mention of drying time of tray adhesive in achieving appropriate bonding strength of tray material and impression material. Focal epithelial hyperplasia (FEH) is a human papillomavirus (HPV)-induced alteration of the oral mucosa that presents with a clinically distinct appearance. 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. Three definitive casts, each with 3 linearly positioned implant analogs at relative angulations 0, 30, and 40 degrees, were fabricated with passively fitted corresponding reference frameworks. 2019 Apr;11(2):128-137. 私たちと共有してください!. 82 2 440 7518, Email: ysprosth@hanmail.net Female participants and participants with denture-related mucosal irritation had higher GPA-pa SF scores at all time points analysed. ): GLUMA (49.02 ± 3.32) > Control (48.61 ± 3.54) > Tooth mousse (48.34 ± 2.94). When Model 2, 3 and 4 are compared with Model 1, they showed narrowing of stress distribution pattern in the cortical bone as the height of the polyoxymethylene resilient material abutment increases. 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. The basic data was subjected to statistical analysis by ANOVA and Student's t-test. To record the vertical gap between reference frameworks and analogs in duplicate casts, a light microscope with image processing was used. Journal of Advanced Prosthodontics. J Prosthodont Res 2018;62:65–74. GC Tooth Mousse does not affect the retentive ability of glass ionomer and resin modified glass ionomer cement, but it decreases the retentive ability of zinc phosphate cement. Specimens treated with EDTA showed the highest shear bond strength and the lowest contact angle for both groups. Resin modified glass ionomer cement exhibited the highest retentive strength and all dentin treatments resulted in significantly different retentive values (In Kg. The remaining portion of the impression was poured with the gypsum material. Dent Mater 2007;23:893–899. The hybrid ceramic restorations can be recommended with no complications.

Information regarding tooth ratio in the Korean population may be useful to clinicians when restoring anterior teeth. The denture bases without and with relining were divided into 2 groups (each n = 20). However, recently, due to the continuous rise in the price of gold, an interest towards materials to replace gold alloy is getting higher. Only adhesive failure was observed at the metal-resin interface in the non-primed specimens, while the primed specimens showed mixed failure of adhesive and cohesive failure. The angle between orbitale and ala-tragus averaged 13.6 degrees. The distortion values of each splinting methods were measured using coordinate measuring machine, capable of recordings in the x-, y-, z-axes. Data were statistically analyzed by one-way analysis of variance with Tukey HSD tests (α=.05). An osteoblast precursor cell line, were used to evaluate the cell responses to the 3 groups. The thickness of ceramic disc increased, the VHNs of all four resin types were decreased (P<.05). 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). When resin cements of adhesive monomers are applied over air-abraded zirconia restorations, the degree of fit does not influence the resin-zirconia microtensile bond strength. CONCLUSION The study groups were divided into a control group (no membrane) and two experimental groups (SF membrane and Bio-Gide®). A stainless steel metal model with 6 implants embedded was used as a master model. 45 extracted bicuspid teeth were prepared for receiving zirconia crowns, with different occlusal preparation designs A=15, SA=15 & NA=15. Also, mode of failure seen was predominantly cohesive for both EDTA and pumice prophylaxis. There is a considerable variation between the measured marginal and internal gap values for the Zr copings fabricated by the (CAD4DENT-CAD/CAM). Sixty two implants were inserted into 47 patients, and their ISQ values were measured using Osstell™ and Osstell™ Mentor. Additionally, no significant difference was observed between the parallel and mesial angulated groups. Statistical analysis was performed with the use of Kaplan-Meier analysis, Chi-square test and odds ratio. Liebermann A, Wimmer T, Schmidlin PR, Scherer H, Löffler P, Roos M, Stawarczyk B.

After the resin cement was bonded to the zirconia using a Teflon mold, photopolymerization was carried out. Rinastiti M, Özcan M, Siswomihardjo W, Busscher HJ. Gender and denture-related mucosal irritation affected the GPA-pa SF scores. 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. J Adv Prosthodont. The counter die with the 0.5 mm clearance was used for fabricating the wax patterns for the metal copings. Venturini D, Cenci MS, Demarco FF, Camacho GB, Powers JM. Maxillary labial and buccal frena are considered as normal anatomic structures in the oral cavity. The ala-tragus line and the occlusal plane lines were for all practical purposes parallel. These results indicate that the new developed Ti-Ta-Nb alloy and its nanoscale Ti-Ta-Nb coatings may be useful as an implant material. The impression made with the polyvinylsiloxane was first poured to prepare the die cast. 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. In group LCT, the glass fiber post (LuxaPost) cementation and core foundation was accomplished with composite resin (LuxaCore-Dual) in separated procedures. 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. 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. SF membranes successfully enhanced comparable volumes of bone regeneration in calvarial bone defects compared with collagen membranes. We aim to find the clinical significance of surface treatments by observing the differences in the stabilization stages of implant stability. However, the mean ΔE values were less than 3.7ΔE units which is rated as a match in the oral environment. However, there were no significant differences in fracture strength between the groups. How the ISQ values measured by Osstell™ and Osstell™ Mentor are related, and whether the ISQ values acquired from the two machines changes in accordance with changes in implant stability are not yet fully understood. Reports of councils and bureaus revised American National Standards Institute/American Dental Association specification no 27 for resin-based filling materials. Total of fifty metal ceramic crown samples were fabricated. Additionally, the accuracy of the implant cast was not different for the parallel and 10° mesial angulated groups. The simplicity of this technique facilitates and justifies its routine use in fabrication of the fixed partial denture. Clinical findings revealed tooth sensitivity, severe enamel erosion resembling veneer preparations, and the presence of anterior open bite. Repeated firings (3, 5, 7, or 9) were performed, and the color of the specimens was compared with the color after the initial firing. Fleming GJ, Awan M, Cooper PR, Sloan AJ.

Polishing methods of an alumina-reinforced feldspar ceramic. 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. 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. The disks were cast by two types of metal. Many dentists use desensitizing agents to prevent hypersensitivity. Considering the lower cost and lesser risk of infectious transmission from animal tissue, SF membranes are a viable alternative to collagen membranes for GBR. 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. The a* values increased for 1 mm and 1.5 mm thicknesses (P<.01), while it decreased for 0.5 mm specimens. A repeated measures ANOVA and Bonferroni post hoc test were used to analyze the data (n = 10, α=.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 aim of this study was to identify in vitro antimicrobial activity of the tissue conditioner containing silver nanoparticles on microbial strains, Staphylococcus aureus, Streptococcus mutans and Candida albicans. The proportions of porosity on the fractured surface were calculated on the images acquired through the scanning electronic microscope. In the second stage surgery, the values of fifty implants inserted into thirty seven patients were measured. The height and width of buccal supra-implant soft tissue were measured.
