Abstract

The purpose in this study, investigation effect of different ambient temperature on mechanical and tribological behaviour of three different composite restorative materials. In this study, hardness, surface roughness and direct-contact wear behaviors of composite materials were investigated in chewing test experiments (5 °C, 37 °C and 55 °C) at three different ambient temperatures. Chewing test experiments were performed in distill water at three different ambient temperatures as 50 N bite force bite force of upper jaw, 0.7 mm lateral movement of lower jaw, 240,000 mechanical loading, 1.6 Hz chewing period and 6 mm diameter Al2O3 antagonist material. The hardness, surface roughness and mean wear volume loss values of composite materials were determined after each chewing test group. In addition to, a random specimen was selected from each test group with 3D profilometer and Scanning Electron Microscope (SEM) images were taken for analysis of wear tracks. As a result of this study, it has been observed that the decrease hardness values of all composite materials of tested with increasing chewing ambient temperature. The organic matrix structure of the monomer of the composite material contributes to the increased surface temperature of the chewing material and the more significant surface roughness of the composite material.

Özet

Bu çalışmanın amacı, farklı ortam sıcaklıklarının üç farklı kompozit restoratif malzemesinin mekanik vetribolojik davranışları üzerindeki etkisinin incelenmesidir. Bu çalışmada, kompozit malzemelerin sertlik,yüzey pürüzlülüğü ve direkt-temas aşınma davranışları üç farklı ortam sıcaklığındaki çiğneme testdeneylerinde (5 ℃, 37 ℃ ve 55 ℃) incelenmiştir. Çiğneme test deneyleri saf su içerisinde üç farklı ortamsıcaklığında 50 N üst çene ısırma kuvveti, 0.7 mm alt çene yanal hareketi, 240.000 mekanik yükleme,1.6 Hz çiğneme periyodu ve 6 mm çapında Al2O3 karşı malzeme olarak uygulanmıştır. Kompozitmalzemelerin her çiğneme test grubu sonrasında sertlik, yüzey pürüzlülüğü ve ortalama aşınma hacimkaybı değerleri belirlenmiştir. Ayrıca, her test grubundan rastgele numuneler seçilerek 3D profilometreve taramalı elektron mikroskobu görüntüleri alınarak aşınma yüzeyi analizleri yapılmıştır. Bu çalışmasonucunda, çiğneme ortam sıcaklığının artması ile test edilen tüm kompozit malzemelerin sertlikdeğerlerinde azalmalar gözlemlenmiştir. Kompozit malzemenin monomer yapısında içerdiği organikmatris yapısı çiğneme ortam sıcaklığının artması ile kompozit malzemenin daha belirgin yüzeypürüzlülüğüne sahip olmasına katkı sağlamıştır.
