Objective: This study aims to compare the biomechanical behavior of the implant-abutment connection against in-vitro loading in the use of Straight and Angled standard fabricated abutments and CAD/CAM abutments in a locally designed and produced special connection.
Materials and Methods:Ti Grade5 Straight abutment was used in the first group, 25° Angled Ti Grade5 fabricated abutment was used in the 2nd Group, and TiBase abutment was used in the 3rd Group. The implant diameter was used as 4.8 mm, and each sample was fixed on the implant manually or using a torque wrench. The crowns were cemented or screwed to the superstructures, which were torqued or manually tightened to 30 Ncm twice a day apart, and the first images were taken with the Micro-CT device. Four-year use of each sample was simulated in 1000000 cycles in the chewing simulator application. Micro-CT was again used to measure implant-abutment contact areas after loading.
Results: There is a significant difference between all groups, except for the range in the tightening group with 30Ncm torque before simulation, only on one side and at the internal measurement point.
Conclusion: When we look at the compatibility of the connection screw with the abutment before and after the chewing simulation; In general, it has been noticed that the fabricated straight abutments and Universal Ti-Base abutments have a tighter connection gap, while the connection of Angled abutments is weaker. When looking at the compatibility of the abutment contact areas with the implant body before and after the chewing simulation; It has been observed that the tightest connection values are generally created by CAD/CAM and Straight abutments, to a greater extent than screw fit.

Amaç: Bu çalışmada, yerli ve milli olarak tasarlanıp üretilen özel bir bağlantıda Düz ve Açılı standart implant destekleri ve CAD/CAM destekler kullanılarak in-vitro yüklemeye karşı implant-abutment bağlantısının biyomekanik davranışının karşılaştırılması amaçlanmıştır.
Materyal ve Metod: Birinci grupta Ti Grade5 Düz destek, 2. Grupta 25° Açılı Ti Grade5 üretilmiş destek ve 3. Grupta TiBase destek kullanılmıştır. İmplant çapı 4,8 mm olarak kullanılmış ve her bir örnek implant üzerine manuel olarak veya tork anahtarı kullanılarak sabitlenmiştir. Kronlar üst yapılara simante edilmiş veya vidalanmış, üst yapılar günde iki kez arayla 30 Ncm tork veya manuel olarak sıkılmış ve ilk görüntüler Mikro-BT cihazı ile alınmıştır. Her bir örneğin dört yıllık kullanımı çiğneme simülatörü uygulamasında 1000000 döngüde simüle edilmiştir. Yükleme sonrasında implant-destek temas alanlarını ölçmek için yine Mikro-BT kullanılmıştır.
Bulgular ve Sonuç: Simülasyon öncesi 30Ncm torklu sıkma grubundaki aralık hariç tüm gruplar arasında iç ölçüm noktasında anlamlı fark bulunmaktadır. Çiğneme simülasyonu öncesi ve sonrası bağlantı vidasının destek ile uyumuna bakıldığında; genel olarak, üretilmiş düz destekler ve Üniversal Ti-Base desteklerin daha sıkı bağlantı boşluğuna sahip olduğu, açılı desteklerin bağlantısının ise daha zayıf olduğu görülmüştür. Çiğneme simülasyonu öncesi ve sonrası destek temas alanlarının implant gövdesi ile uyumuna bakıldığında; genel olarak en sıkı bağlantı değerlerinin vidalı desteklere göre daha fazla oranda CAD/CAM ve Düz destekler tarafından oluşturulduğu görülmüştür.
