영문 초록

This study was designed for comparison of shear bond strengths and failure patterns of four experimental groups which combinated mesh-backed metal brackets and texture based ceramic brackets (Transcend series 2000^(™)) with chemically cured resin (Mono Lok2^(™)) and visible light cured resin (Transbond^(™)). Brackets were bonded on the extracted human bicuspids, after etching them by manufacturer´s recommand, and the shear bond strengths were measured on the Instron machine after 24 hrs passed in the 37°C water bath. The results were as follows. 1. Ceramic brackets, transcend series 2000^(™), bonded with MonoLok2^(™) showed statistically higher shear bond strength than mesh-backed metal brackets bonded with MonoLok2^(™). 2. There was no significant difference in shear bond strengths between metal and ceramic brackets bonded with Transbond^(™). 3. Ceramic brackets bonded with both Transbond^(™) and MonoLok2^(™) showed primarily fractures bet?ween brackets adhesive interface. 4. Enamel crack was not found in anyone specimen.
