Abstract

The aim of this study was to evaluate experimentally frictional forces produced between different brackets and arch wire materials. In the study, the frictional forces between four brackets (Stainless steel, porcelain, .polycarbonate and stainless steel friction free) and various arch wire materials were tested using a three dimensional friction testing apparatus. Friction increases as the wire size increases. FF bracket showed significantly lower frictional forces compared to all other brackets. Slippery NiTi wires whose surfaces were hardened by ion implantation method showed significantly low frictional values compared to SS, Co-Cr, NiTi and TMA wires. Twist flex also generated lower frictional resistances compared to NiTi, TMA and SS wires in all brackets. The frictional values obtained by SS brackets were higher than the others. The reason of this was the burrs on the slot of these brackets due to the manufacturing technique.

Özet

Bu çalışmanın amacı, farklı braket ve tel materyalleri arasında ortaya çıkan sürtünme kuvvetlerini deneysel olarak incelemektir. Çalışmada, 4 çeşit braket (paslanmaz çelik, porselen, polikarbonat ve paslanmaz çelik sürtünmesiz) ile değişik materyal ve çapta ark telleri arasındaki sürtünme kuvvetleri üç boyutlu bir test cihazı kullanılarak incelenmiştir. Tel çapı arttıkça sürtünme kuvvetleri de artmaktadır. Sürtünmesiz paslanmaz çelik (FF) braket diğer tüm braketlere göre istatistiksel olarak anlamlı düzeyde düşük sürtünme değerleri göstermektedir. İyon implantasyon metoduyla yüzeyi sertleştirilen ve pürüzleri azaltılan Slippery NiTi tel; SS, Co-Cr, NiTi ve TMA tellere oranla anlamlı düzeyde düşük sürtünme değerlerine sahiptir. Twist flexte, tüm braketlerde NiTi, TMA ve SS tellere kıyasla daha düşük sürtünme göstermektedir. SS braketlerle elde edilen değerler diğer braketlere göre daha yüksektir. Bunun nedeni, bu braketlerin üretim tekniğine bağlı olarak slot kenarlarında gözlenen çapaklardır.
