Immediate Metal Implants into Extraction Sockets.

Abstract: : The objective of the research is to develop an artificial tooth replacement that could be placed immediately into the wound socket of an extracted tooth to restore function. This tooth substitute will be a prosthesis consisting of two parts: the root portion, a metallic implant with an open-pore system of sintered wire fiber aggregate attached to a solid metal road; a crown portion attached to the portion of the metal rod that extends into the oral cavity and places the implant in function. Dogs have been the experimental animal. Implants have been embedded in the bone for various survival times up to, and including, one year. The solid metal posts of the implants have been exposed in the oral cavity for six months with no inflammatory reaction. The technic of placing the implant has been improved so that rejections are negligible. Histologic specimens demonstrate definite bony ingrowth into implant. Two types of metal implants have been used: titanium and vitallium. (Author)
