| 摘要 | PURPOSE: To provide a point for mounting and demounting a bracket for orthodontics, by which a heating area of the bracket, can be enlarged, the bracket can be surely held in the mounting and demounting point, and the force necessary for removing the bracket from the teeth can be reduced without heating the teeth. CONSTITUTION: A point for mounting and demounting 10 is closely bonded around a median distal side 5 of a bracket for orthodontics 1, and in a saddle- shaped groove 6. The point 10 rapidly heats the bracket 1, for softening the adhesives used for adhering the bracket 1 to the teeth. In accordance with the increase of the viscosity of the adhesives, the bracket 1 becomes rotatable around the teeth, and can be removed from the teeth. COPYRIGHT: (C)1992,JPO |
