Purpose: Ceramic self-ligating brackets were developed recently, however, only few comparative studies had been reported about their bond strengths and friction. The aim of the study was to compare shear bond strengths and friction forces of various self-ligating ceramic brackets. Materials and methods: The present study is divided into two parts. In shear bond strength test, bovine teeth were used as a substitute for human teeth. Five groups of brackets (three ceramic self-ligating brackets including ClippyC, GeniusCrystal, DamonClear2, ClarityAdvanced (conventional ceramic bracket), Damon3MX (metal self-ligating bracket), were used and debonded with 12 brackets in each group. The shear bond strengths …
