Abstract

The investigation of stres s formed in composite inlays byfinite element stress analysis. The purpose of this study was to investigate the stresses formed under the vertical and lateral forces in composite inlays by three dîınensional finite element stress analysis method. For this purpose, a MOD inlay cavity was performed and sections were obtained from the second lover molar tooth to which composite inlay applied. Then real three dimensional mathematical model was established by computer. The stresses formed under the vertical and lateral forces in two different groups were examined by SAP 90 program in ternıs of Von Misses stress values. The stress value occured in the mesial step under the vertical forces was found to be 37.5 Mpa and in the distal step under the vertical forces was found to be 24 Mpa in composite inlay. The stress value occured in the mesial step and distal step under the lateral forces were found to be 3 Mpa in composite inlay. As a result; composite inlay and controlgroup formed under vertical forces were compared, statistically important result were found (P

Özet

Kompozit inleylerde oluşan stresin sonlu elemanlar stres analiz yöntemi ile incelenmesi. Bu çalışmanın amacı; kompozit inleylerde vertikal ve lateral kuvvetler altında oluşan streslerin üç boyutlu sonlu elemanlar stres analiz yöntemiyle incelenmesidir. Bu amaçla, MOD inley kavitesi açılarak kompozit inley yapılan alt ikinci molar dişten kesitler alınarak gerçek üç boyutlu matematiksel model bilgisayar ortamında oluşturulmuştur. SAP 90 programı kullanılarak iki farklı grupta vertikal ve lateral kuvvetler altında oluşan stresler Von Misses stres değerleri cinsinden saptanmıştır. Kompozit inleylerde vertikal yük altında mesial basamakta oluşan stres değeri 37.5 Mpa saptanırken, distal basamakta 24 Mpa olarak saptanmıştır. Kompozit inleylerde lateral kuvvet altında mesial basamakta oluşan stres değeri 3 Mpa saptanırken, distal basamakta da 3 Mpa olarak saptanmıştır. Sonuç olarak kontrol grubunun ve kompozit inley grubunun vertikal kuvvetler altında oluşan stres değerleri karşılaştırıldığında, aradaki fark is-tatistiksel olarak anlamlı bulunmuştur. (P
