Abstract

PURPOSE:To produce an implant material having a great affinity for a living body and superior strength by adding fine powder of hydroxy-apatite to a soln. prepd. by hydrolyzing alkyl silicate, applying the resulting sol to the surface of a metal, drying and calcining the applied sol. CONSTITUTION:Ethyl silicate is hydrolyzed by thorough mixing with a soln. of ethanol in hydrochloric acid and fine powder of hydroxy-apatite is added to the resulting soln. and mixed to obtain sol. This sol is applied to the surface of a metal such as stainless steel or Ti, dried and calcined to form a bioglass film having high adhesive strength to the surface of the metal. Thus, an implant material useful as an artificial tooth or bone is produced.

In the case of bioacceptable and bioinert materials, they are not directly bonded to the bone and are fixed only by a single mechanical fit, so there is a risk of loosening or falling off after long-term use.

On the other hand, in the case of bioactive materials, especially apatite, the compressive strength is sufficient, but the tensile, bending, and torsional strengths are insufficient. Therefore, it cannot be used in areas subject to excessive tensile stress.

One method of attempting this is to create a material that satisfies both strength and biocompatibility by coating the surface of stainless steel or titanium alloy with bioglass. This problem is due to the weak adhesive strength between the coating film and the metal, and the fact that coating has traditionally been done by melting bioglass, which has poor workability and is not suitable for mass production.
