发明名称 ORTHODONTIC BRACKET
摘要 An orthodontic bracket (10) for coupling an archwire (18) with a tooth includes a bracket body (12) that has an archwire slot (16) adapted to receive the archwire (18). A movable member (14) is engaged with the bracket body (12) and is movable between an opened position and a closed position. The bracket body (12) and movable member (14) are made from a transparent or translucent ceramic for improved aesthetics. The bracket body (12) may include one or more stop surfaces that limit movement of the moveable member (14) in the gingival direction. The bracket body (12) may include a support surface (40) that is positioned lingually of a labial edge of the archwire slot (16). The bracket body (12) may be made of a polycrystalline ceramic having a grain size distribution characterized by an average grain size in the range of larger than 3.4 µm to about 6 µm.
