This method has the advantage that the acrylic artificial tooth and the acrylic denture base are chemically bonded firmly.
しかし、このようにして得られたアクリル義歯床は、脆
く割れ易い欠点を有するばかりでなく、未重合モノマに
よる為置注を有する。However, the acrylic denture base obtained in this manner not only has the disadvantage of being brittle and easily cracked, but also suffers from residual damage due to unpolymerized monomers.
このようなアクリル義歯床の欠点を除去するものとして

ル人工歯の使用が大きく制限されている。Although this polysulfone denture base has high mechanical strength and excellent impact resistance, it does not chemically bond with the acrylic artificial teeth used for boat fishing, so the acrylic artificial teeth easily fall off the denture base. There is. For this reason, a method of attaching a special retaining shape to acrylic artificial teeth has been proposed, but there are many cases in which the retaining shape cannot be attached, and in reality, the use of acrylic artificial teeth is severely restricted.

［作用］
本発明の接合方法によりポリサルホン床義歯を製作する
と、アクリル人工歯がポリサルホン義歯床に強固に維持
されたポリサルホン床義歯が得られる。[Function] When a polysulfone base denture is manufactured by the bonding method of the present invention, a polysulfone base denture in which an acrylic artificial tooth is firmly maintained on a polysulfone denture base can be obtained.

サルホン義歯床に対応することができる。Furthermore, according to the present invention, in cases where there is a small gap between the acrylic artificial tooth and the alveolar mucosa, that is, in cases where the acrylic artificial tooth is bonded to a thin polysulfone denture base, sulfone resin molten at high temperature is press-fitted by compression molding. During this process, the resin attached to the artificial tooth deforms appropriately under high temperature and pressure, allowing it to accommodate thin polysulfone denture bases.
