This report summarizes recent developments concerning an improved high-density, high-strength grooved alumina tooth root structure of the nonbifurcated design for use in monkey, baboon, and human implant studies. The basic improvements incorporated this project year are a method of improved surgical implant procedures and a modified root style to facilitate reconstructing the tooth root. Roots with protruding ellipticl posts and roots with recessed elliptical sockets for crown attachment have been manufactured. Roots with recessed elliptical sockets have a higher acceptance rate following implantation. This apparently results from the isolation from biomechanical stresses during the critical initial ingrowth period of the implant. A specially designed, tapered diamong dental burr has been developed to produce a socket which provides good initial stabilization and fit. Once firmly implanted and stabilized by bone ingrowth into deep surface grooves, the implant can be reconstructed using a two-step dental restoration technique. It appears that approximately a 2-month stabilization period is necessary prior to reconstruction. Author
