Abstract (2. Language): 
Implant therapy is widely used for the treatment of edentulous patients. Placing implants to the interforaminal region of an edentulous mandible and constructing overdenture prosthesses is a good alternative. However, there is no consensus on the number of the implants and whether or not using distal extensions. For that reason in our study, we tried to find out the effect of implant retained overdenture prosthesses with or without distal extensions on the stress distribution at the implant interface. In our study we prepared two, three dimentional finite element models representing bar retained overdenture prostheses with 7mm distal extensions and no distal extensions built over 3 implants. 25 N horizontal, 100 N vertical and 103 N oblique force were aplied each model. The stresses were investigated using the ANSYS 8.1 workbench programme. The results of our study show that the maximum stress formations were seen on the cortical bone distal to the implant which is nearest to the side where the forces were applied.

Abstract (Original Language): 
Tam dişsiz çenelerin protetik tedavilerinde implant uygulamaları çok sıklıkla kullanılmaktadır. Alt çene total dişsizlik vakalarında interforaminalar bölgesine uygulanan çeşitli sayıda implant üzeri barlı overdentureTar da bir tedavi alternatifidir. Yapılan implant üstü barlı overdenture protezlerde kullanılacak implant sayısı ve barların distal uzantılarının olup olmaması üzerine hala tam bir görüş birliği yoktur. Çalışmamızda, interforaminal bölgeye 3 adet implant yerleştirilerek yapılan implant üzeri protezlerde, distal uzantılı ve distal uzantısız barlı protezlerin ve sayılarının, implant kemik ara yüzeyindeki stres dağılımına etkisinin incelenmesi amaçlandı. Çalışmamızda 3 adet implant üzerine 7 mm distal uzantılı ve distal uzantısız barlı protezleri temsil eden 2 adet üç boyutlu sonlu elemanlar modeli hazırlandı. Her modele, 25N horizontal, 100 N vertikal, 103 N oblik kuvvet uygulandı. Oluşan stresler ANSYS 8.1 Workbench programı ile incelendi. Çalışmamızın sonucuna göre maksimum stres değerleri kuvvetin uygulandığı tarafa en yakın implantm distalindeki kortikal kemikte tespit edildi. Spongioz kemikte belirlenen maksimum stres değerleri ise düşük olup genellikle implantların apeksinde ve implantlan çevreleyen kemikte saptandı.
