Surgical Tooth Implants, Combat and Field.
Abstract
Experimental ceramic prosthetic tooth root structures were developed and implanted in rhesus monkeys. Early implants incorporated a metallic post upon which a crown could be fitted. Later versions had integrated ceramic posts, cast as part of the root structure. Two types of root surface characteristics were experimentally developed and tested in vivo. The first was the as cast mat surface of the high density alumina root core. The second was porous alumina coating on the high density core. Most of the in vivo experiments were conducted using the smooth mat surface root structures. Early indications with implanted root structures out of occlusion appeared favorable. Later implants fitted with crowns at the outset were, in general, not clinically successful. Recent implants with the aforementioned surface coating continue to be rigidly bound in their sockets with no bone resorption occurrring after several months. These implants were fitted with crowns and are in function. (Author)
