<p>PURPOSE:To easily and precisely press a bracket to a correct position by providing a body part of a sectionally inverted U shape having a frame part made of a sectionally die curved plate and two bulging horizontal rod leg parts and a dosal fin-shaped holding part to the curved outside surface of the frame part made of the die curved plate. CONSTITUTION:The holder 1 has the frame part 2 made of the sectionally die curved plate and the bulging horizontal rod leg parts 3, 3' juxtaposed along the two bottom end edges thereof to form the body part of the sectionally inverted U shape and is constituted of polyethylene, polypropylene, polyvinyl chloride, etc. The frame part 2 made of the sectionally die curved plate and the bulging horizontal rod leg parts play the role of assuring a space to embrace the bracket 10 for orthodonotia and to prevent an adhesive agent from spreading to the lower part of the wing. In addition, the dosal fin-shaped holding part 4 is provided to the curved outer surface of the frame part 2 to facilitate stable gripping with the fingers. The entire part thereof is thus surely brought into pressurized contact with the correct position of the entire surface of the tooth.</p> |
