To the human body of the denture floor and the denture floor where invention of long-cherished desire, supports the population tooth and the population tooth and at the same time designates the poly- methyl methacrylate as the main component to be the denture which has with the reverse side equipment material which is provided on the surface which is locked, as for the reverse side equipment material, general system< Conversion 1 >(M+n=50 - 2000) with the gel it is the silicone rubber which was made to polymerize in the silicone which is shown including echirenjimetakurireto. This being similar, the denture floor (the resin) with, adhesive strength with the silicone rubber which is the reverse side equipment material it improved considerably with the mechanism which differs from the silicone rubber which adds MMA.本願の発明は、人口歯と、人口歯を支持し且つポリメタクリル酸メチルを主成分とする義歯床と、義歯床の人体へ固定する面に設けられる裏装材とを備えた義歯であり、裏装材は、一般式【化1】(m+n=50~2000)で示されるシリコーンにエチレンジメタクリレートを加えてゲル重合させたシリコーンゴムである。これにて、MMAを添加したシリコーンゴムと異なるメカニズムにより、義歯床(レジン)と、裏装材であるシリコーンゴムとの間の接着力を著しく向上した。
