ARTIFICIAL TOOTH TO BE USED FOR BRIDGE PONTIC PART, AND METHOD FOR PRODUCING BRIDGE

摘要

PROBLEM TO BE SOLVED: To simply, easily, inexpensively and efficiently produce a bridge by using an artificial tooth.;SOLUTION: The artificial tooth to be used for a bridge pontic part includes: a front layer part 2 whose front surface is formed to be a tooth shape; and a basis part 3 which is connected to the front layer part 2 so as to be separable, and formed through the use of an eliminable material to be eliminated by heating. A bridge producing method includes: a process for connecting the basis part 3, which is formed with the eliminable material so as to be eliminated by heating, to the front layer part 2 having the front surface formed in a tooth shape, so as to be separable, and then, for producing the artificial tooth 1 to be the pontic part 5 of the bridge 4; a process for producing an elimination model 9 to be arranged in the basis part 3 of the artificial tooth 1 by connecting a support base device 6 which is connected to a support base with the eliminable material; a process for separating the front layer part 2 from the elimination model 9, casting a metal into the elimination model 9, which is separated from the front layer part 2, and producing a metallic frame 7; and a process for fixing the front layer part 2 to the metallic frame 7.;COPYRIGHT: (C)2004,JPO
