[Physicochemical characteristics of new reinforcement ceramic implant].

Investigation of the physicochemical characteristics of reinforcement ceramic implant materials which have needle crystal produced the following results. 1. Simple diopside and hydroxyapatite with diopside have enough dynamic intensity of both the implant in point of bending intensity and the breaking toughness. 2. Simple diopside and hydroxyapatite with diopside go well as biomechanics because of their Young's modulus being close to the surrounding bone. 3. Diopside in pseudo-body fluid developed hydroxyapatite on surface like bioglass, and this resulted in high possibility of direct bond with bone. 4. The results of this study indicate that the diopside and hydroxyapatite with diopside have enough dynamic intensity and are bioactive dental implant materials.
