Abstract
The utility model provides a compound artificial tooth, including buffer layer, full enamel coating and toughening layer. The buffer layer is hugged closely in the root of the tooth surface, and full enamel coating subsides are applied in the surface of buffer layer, and toughening layer pastes the surface that applies in full enamel coating. The mesh that mechanicalness, acid -base nature and the bacillary injury of boundary's environment were suffered to nerve and other tissues in the buffer layer mainly played the protection root of the tooth and prevents the root of the tooth, full enamel coating mainly supports for artificial tooth overall structure provides the mechanics, toughening layer avoids chewing the external hard thing of in -process and causes the damage to full enamel coating. Compound artificial tooth has reduced the probability that bursts apart of full enamel coating, has both guaranteed that full enamel coating provided sufficient mechanical mechanical properties for the artificial tooth, simultaneously, because the root of the tooth of deciduous teeth base members and the mechanical wear that the gum did not receive full enamel coating have been protected in buffer layer and toughening layer's existence.
