Publication Metadata only Retrospective Analysis of Lithium Disilicate Laminate Veneers Applied by Experienced Dentists: 10-Year Results(QUINTESSENCE PUBLISHING CO INC, 2019) ÖZKAN, YASEMİN; Asian, Yilmaz Umut; Uludamar, Altay; Ozkan, YaseminPurpose: To report on the 10-year clinical treatment outcomes for a strictly applied clinical protocol for pressable lithium disilicate glass-ceramic laminate veneers (LDLVs) placed by two experienced dentists. Materials and Methods: A 10-year follow-up assessment of 364 LDLVs placed in 41 patients was undertaken with the clinical criteria color/esthetic match of the porcelain surface, chipping and fracture occurrence, marginal discoloration, and integrity, assessed using the modified United States Public Health Service scoring system. Results: After 10 years, the survival rate was 97.4%. Complications occurred in 1.64% of the restorations (fractures and debonding in 0.55% and 1.09%, respectively). Conclusion: A strict, repeatable protocol for placing veneers with experienced dentists yielded good results.Publication Open Access Two-body wear of occlusal splint materials against different antagonists(BMC, 2020-12) ÖZKAN, YASEMİN; Yildiz Domanic, Kubra; Aslan, Yilmaz Umut; Ozkan, YaseminBackground This study aimed to demonstrate that the material of the occlusal splint can be chosen according to the needs of individual patients and contribute to the knowledge of the wear rate of these materials. Methods In this study, four occlusal splint materials (Sr Ivocap Heat Cured, Valplast, SR Ivocap Elastomer and Eclipse) and three antagonists (natural tooth enamel, inCoris TZI and IPS e.max Press ceramic materials) were used. Each wear test was performed using a chewing simulator (n = 16; test load: 50 N; number of cycles: 10,000, 20,000 and 30,000; continuous rinsing with water at 30 degrees C for the wet condition). The Shapiro Wilk test was used for normal distribution suitability. Antagonist on average wear quantities both main effects and interactions of material, cycle and condition factors were investigated by Univariate variance analysis. Multiple comparisons were examined using the Games-Howell test. Results There was a statistically significant effect of the difference in materials on the amount of wear (p < 0.001). Furthermore, there was a statistically significant difference among the mean values of all materials (p > 0.001). The highest mean value was obtained with Eclipse (0,318 mu m(3)), and the lowest mean value was obtained with Valplast (0,134 mu m(3)). Conclusion Our study found differences in the in vitro wear rate among various occlusal splint materials.Publication Open Access Comparison of the accuracy of intraoral scanning systems with conventional impression in dentate patient(2020-04-01) ÖZKAN, YASEMİN; Imadettin ALSAYED;Yılmaz Umut ASLANBackground: Over the last years, different intraoral scanningsystems for direct digitalization have been introduced to the dentalmarket. However, the accuracy of these scanners is variable, andlittle information is available. The aim of this in vivo study was tocompare the accuracy of two intraoral scanning systems and thedifference between upper and lower jaw on the accuracy.Methods: 10 patients with full dentition received one conventionalimpression with polyvinyl siloxane (Elite HD+, Zhermack SpA, Italy)and three scans with CEREC OC (Sirona Dental Systems, Sirona,Bensheim, Germany) and Straumann CARES IOS (Intra oralScanner, Basel, Switzerland) for upper and lower jaw. Theconventional impressions were poured and the casts made from itwere scanned and used as the reference model to evaluateprecision and trueness of intraoral scanning virtual modelsprovided by each system. Digital models were analyzed with asoftware (Geomagic Control; Geomagic, Morrisville, USA).Results: The trueness value was 99.88±42.56 μm in upper jaw and82.6±26.81 μm in lower jaw for CEREC OC, and 105.53±25.49 μmin upper jaw, and 109.56±36.84 μm in lower jaw for CARES IOS.The differences between these two systems were not statisticallysignificant (P>0.05), but statistically significant difference wasfound in the precision (P<0.05). CEREC OC showed higher valuein both upper and lower jaws.Conclusion: CEREC OC was more precise than CARES IOS andat a similar level of trueness. No statistically significant differencewas found between upper and lower jaws in both systemsPublication Metadata only İmmediyat implant yüklemesi vaka sunumu(2019-10-31) ASLAN, YILMAZ UMUT; AKMANSOY, ŞÜKRÜ CAN; ÖZKAN, YASEMİN; Demirkılıç Z., Keban Aydın S., Aslan Y.

Computer-aided impressions have been transforming the dental implant field with these developments. The aim of this in vivo study was to compare the accuracy and time efficiency between two intraoral scanning systems in single tooth implant treatment. Methods: 10 patients with single tooth bone level implant (Straumann, Basel, Switzerland) received one conventional impression with polyvinyl siloxane and three scans with 2 different intra-oral scanners (CEREC AC Omnicam and Straumann CARES IOS). The time required for the impressions was measured at this stage. The casts obtained from conventional impressions were scanned as the master model to evaluate accuracy. Digital impression files were analyzed using a software (Geomagic Control). Independent Samples Test was performed for trueness and precision. One-way ANOVA was executed for time efficiency. Least significant difference test for post hoc comparison was conducted (p<0.05). Results: The differences between the two systems regarding trueness and precision were not statistically significant (P>0.05), but a statistically significant difference was found in the time efficiency (P<0.05). CEREC AC showed the lowest mean values in time measures. Conclusions: There was no difference regarding accuracy in comparison between CEREC AC Omnicam and CARES. CEREC AC Omnicam was found to be superior in terms of time efficiency in comparison to CARES and conventional impressions.Publication Metadata only Fracture Resistance of Porcelain Laminate Veneers(AVES PRESS LTD, 2018) KAHRAMANOĞLU, ERKUT; Tugcu, Erhan; Kahramanoglu, Erkut; Aslan, Yilmaz Umut; Ozkan, YaseminIn recent dentistry, laminate veneers have gained widespread utilization as a conservative treatment option of unaesthetic anterior teeth. The continued development of dental ceramics offers clinicians many options for creating highly aesthetic and functional porcelain veneers. The behavior of these restorations against the functional loads plays an important role in their success. Many studies have evaluated the fracture resistance of laminate veneers in vitro and in vivo.
