Amaç: Sürtünme, ortodontide mekanoterapiye direnç gösteren ve etkin diş hareketini sağlamak için dikkatle değerlendirilmesi gereken bir olgudur. Bu çalışmanın amacı, üç farklı tipteki kapaklı lingual ortodonti braketleri ile eşlenen nikel titanyum ve paslanmaz çelik tellerin 0 °, 5 ° ve 10 ° açılanmalarda oluşturduğu statik ve kinetik sürtünme dirençlerini değerlendirmektir. Bu çalışmanın sıfır hipotezi ortodontik ark telleri ile eşlenen üç farklı tipteki kapaklı ortodonti braketlerinin sürtünme direnç değerleri arasında anlamlı bir farklılık olmadığıdır. Gereç ve yöntem: Evolution™, In-Ovation® L ve Phantom ™ sağ üst kanin braketleri (0,018x0,025 inç slot) ile 0,016 inç nikel titanyum, 0,016 inç paslanmaz çelik ve 0,016x0,022 inç boyutlu paslanmaz çelik ark telleri arasındaki sürtünme dirençleri kuru ortamda test edildi. Sürtünme dirençleri evrensel test cihazı ile değerlendirildi. Ayrıca braketlerin slot genişliği ölçüldü. Braket slotlarının yüzey pürüzlülüğü atomik kuvvet mikroskobu ve taramalı elektron mikroskobu ile incelendi. Bulgular:Tüm açılanmalardaki tüm kombinasyonlarda en düşük statik sürtünme direnci In-Ovation® L ile 0,016 inç nikel titanyum (2,00±0,02 N) ark teli arasında 0° açılanmada ve en yüksek direnç ise Evolution™ braketler ile0,016x0,022 inç paslanmaz çelik teller arasında oluşmuştur (5,53±0,55 N).Sonuç: Tüm açılanmalarda statik sürtünme dirençleri kinetik sürtünme dirençlerinden daha yüksek bulundu. Phantom ™ braketlerim en büyük slot genişliğine sahip olduğu belirlendi ve In-Ovation® L ve Evolution ™ braketlerin Phantom ™ braketlerinden daha az slot genişliğine sahip olduğu bulundu. Braketler arasında slot yüzey pürüzlülüğü açısından anlamlı farlılık bulunmadı. Çalışmanın sıfır hipotezi reddedildi.
