<p>PURPOSE:To support the crown of the adjacent support tooth on one surface thereof or at two corner parts of one surface thereof in a detachable manner by a partial denture by constituting the title metal jig of loop like parts respectively arranged to a grasping part on both sides thereof and a pair of the barbed legs embedded in the denture base connected to said loop-like parts. CONSTITUTION:When barbed legs 9, 10 are embedded in both end parts or one end part of a denture base 22 and connected to the side surface of a lower support tooth 20, a grasping part 2 is compressed at first against the elastic force of a metal wire 1 by the max. expanded part of the support tooth 20 to be allowed to penetrate in the movable gap part 24 formed between the support tooth 20 and the denture base 22 and subsequently returned to be engaged with the lower part of the max. expanded part of the support tooth 20. At the same time, the outer peripheral surface of the expanded part of the support tooth 20 is supported by loop-like parts 3, 4. When a denture 23 is detached from the support tooth 20 along with the denture base 22, the bar preliminarily provided to the denture base 22 in a protruding state is raised by the fingertip of the hand. By this constitution, the denture base and a clasp can be simply mounted.</p> |
