DEVELOPMENT AND FUNCTIONALITY OF ISOELASTIC DENTAL IMPLANTS OF TITANIUM-ALLOYS

Two types of isoelastic endosseous dental implants were produced and t heir functionality was tested. One type consisted of a porous sintered TiTa30 alloy, the other had a special surface structure consisting of titanium wire loops. Their mechanical properties were optimized by th e production parameter (sintering and diffusion bonding, respectively) . The functionality was tested after insertion into an artificial jaw which had properties corresponding to the natural mandibular. The elas tic properties of both implants were similar to the properties of the bone. In addition the implants have a safe anchorage bone ingrowth. In animal experiments using the implant with surface loops it was observ ed that the bone entered the loops and even extremely small surface ca vities in the wire loops.
