Abstract

Background and Aim: Thepurposeofthisstudywastocomparethefracturestrengthofimplant-supportedcantilevered zirconia frameworks with different connector areas that were fabricated on zirconia and titanium abutments. Materials and Methods:Atotalof40cantileveredimplant-supported three-unit frameworks with two premolar abutments and one molar pontic, both on a 2 titanium or zirconiaabutment,werefabricatedanddividedintofourgroups according to connector areas and abutment materials (TZ-9/TZ-15: titanium abutment-zirconia framework, ZZ-9/ZZ-15: zirconia abutment-zirconia framework). All cantilevered frameworks were cemented and loaded in a universal testing machine until the framework fractured or decemented. Two-way ANOVA with post hoc (LSD) testing was used to analyze the fracture force and the relation between the connector dimension and abutment material.Results: The results of fracture strength tests showed that the mean fracture loads were approximately 188.73, 480.86, 234.41, and 406.03 N for TZ-9, TZ-15, ZZ-9, and ZZ-15, respectively. There was a statistically significant difference in fracture strength between TZ-9 and TZ-15, and between ZZ-9 and ZZ-15 (p≤0.05). Conclusions: The increase in the connector cross-sectional area had a positive effect on the fracture strength of the implant-supported cantilevered zirconia frameworks.

Özet

Amaç: Bu çalışmanın amacı, implant destekli kantilevır uzantılı zirkonya alt yapılarınzirkonya ve titanyum dayanaklardaki vefarklıkonektöralanlarındakikırılmadayanımlarının karşılaştırılmasıdır.Gereç ve Yöntem:2 adet titanyum veya zirkonya dayanak üzerine iki premolar ve bir molar ( kantilever uzantı) içeren konnektör alanı 9 mm2 veya 15 mm2 olantoplam 40 adet implant üstü üç ünite zirkonya altyapı üretildi ve herbir grupta 10 örnek olacak şekilde 4 grubagruba ayrıldı (TZ-9/TZ-15: titanyum dayanak-zirkonya altyapı, ZZ-9/ZZ-15: zirkonya dayanak-zirkonya altyapı). Tüm kantilevır uzantılı zirkonya alt yapılar, kırılma ya da desimantasyon olana kadar, universal bir test cihazında yüklenmiştir. Konektör boyutu ve abutment materyali ile kırılma dayanımı arasındaki ilişkiyi analiz etmek için iki yönlü bir varyans ile birlikte post hoc (LSD) analizi kullanıldı.Bulgular: Kırılma dayanımı testlerinin sonuçları, ortalama kırılma yüklerinin TZ-9, TZ-15, ZZ-9 ve ZZ-15 için sırasıyla yaklaşık 188.73 N, 480.86 N, 234.42 N ve 406.04 N olarak elde edilmiştir. TZ-9 ile TZ-15 arasında ve ZZ-9 ile ZZ-15 arasında kırılma dayanımında istatistiksel olarak anlamlı bir fark bulunmuştur (p≤0.05). Sonuçlar: Konektör kesit alanındaki artış, implant üstü kantilevır uzantılı zirkonya alt yapıların kırılma dayanımını olumlu yönde etkiler.
