Use of Metallic Endosseous Implants as a Tooth Substitute.

摘要

The objective of the study is to evaluate the viability of an artificial metallic prosthesis as a tooth replacement when placed permanently into the jaw bone. The tooth substitute consists of two parts: (1) the root portion, a metallic implant with an open-pore system of sintered metallic fiber aggregate attached to a solid metal rod; and (2) a crown portion, the portion of metal rod that extends into the oral cavity. The root portion is buried in the bone of the mandible or maxillae and the crown portion is exposed in the oral cavity and placed in function with the opposing dentition.
