[Tissue reaction to an implant of a titanium hollow cylinder with a titanium surface spray layer]

Abstract

A new implant consisting of a hollow cylinder of titanium is described. It is well suited to investigate the tissue reaction to several surface textures in the animal experiment (Macaca speciosa). From a test series, for which the implants were surfaced with powdered titan (titan plasma), one was selected which had been worn for 7 months as a partial support. The solid incorporation observed radiologically presents itself, light microscopically, as an immediate growing in of the bone into the rough implant surface. There is no evidence of the formation of a soft tissue bed. Electron microscope pictures reveal that the bone closely anchored to the titan plasma surface.
