| 摘要 |
An artificial dental root comprises a particulate or powdered form of synthetic hydroxyapatite or calcined or sintered synthetic hydroxyapatite or a mixture thereof and an organic polymer binder matrix, the surface area of said artificial dental root to be brought into contact with bone being composed of both a phase of said hydroxyapatite and a phase of said organic matrix. The root is prepared by blending said hydroxyapatite with said organic matrix and molding the blend. The root has adequate, but moderate, affinity for bone and high mechanical strength, and can, if necessary, be extracted without damaging the surrounding bone. |
