Amaç: Bu in vitro çalışmada; farklı 'computer aided design/computer aided manifacturing (CAD/CAM)' materyallerinden hazırlanan implant destekli tam seramik kronların tutuculuk özelliklerinin incelenmesidir. Gereç ve Yöntemler: Her bir grupta 8 adet olacak şekilde 4 farklı CAD/CAM materyalinden (IPS e-max CAD-IPS, Vita Suprinity-VS, Vita Enamic-VE ve Vita YZ ST-ST) toplam 32 adet kron hazırlandı. Kronlar, zirkonya 'abutment'ler üzerine rezin siman ile simante edildi. Kronların tutuculuk özellikleri, universal test cihazında her bir krona dikey yönde 1,0 mm/dk çekme hızıyla ayırma kuvveti uygulanarak test edildi ve desimantasyona sebep olan maksimum kuvvet belirlendi. Elde edilen veriler tek yönlü varyans analizi (ANOVA) ve post-hoc Tukey HSD testleri kullanılarak istatistiksel olarak karşılaştırıldı. İstatistiksel anlamlılık düzeyi p<0,05 olarak değerlendirildi. Bulgular: Gruplar arasındaki retansiyon kuvveti değerleri karşılaştırıldığında anlamlı farklar saptanmıştır (p<0,05). En yüksek retansiyon kuvveti VS grubunda elde edilmiş ve onu sırasıyla IPS, VE ve ST grupları izlemiştir. Sonuç: İmplant destekli tam seramik kronların tutuculuk özellikleri, protetik restorasyon için kullanılan materyal tipinden etkilenmektedir.

Objective: The purpose of this in vitro study was to investigate the retention properties of implant supported full ceramic crowns prepared from different CAD/CAM restorative materials. Material and Methods: A total of 32 crowns, 8 in each group, were prepared from 4 different CAD/CAM materials (IPS e-max CAD-IPS, Vita Suprinity-VS, Vita Enamic-VE and Vita YZ ST-ST). Crowns were cemented on zirconia abutments with resin cement. The retention properties of the crowns were tested in a universal testing machine by applying a separation force at a cross-head speed of 1.0 mm/min in vertical direction and the maximum force leading to decementation was determined. The obtained data were statistically compared using oneway analysis of variance (ANOVA) and post-hoc Tukey HSD tests. Statistical significance was determined at p<0.05. Results: Significant differences were found among the groups with respect to the retention strengh values (p<0.05). The highest retention strength was obtained in the VS group followed by the groups IPS, VE, and ST, respectively. Conclusion: The retentive properties of implant supported full ceramic crowns were affected by the type of material used for prosthetic restoration.
