Abstract

A guided bone regeneration material is disclosed. The guided bone regeneration material includes biodegradable fibers produced by an electrospinning method. The biodegradable fibers produced by the method include a silicon-releasing calcium carbonate and a biodegradable polymer. The silicon-releasing calcium carbonate is a composite of siloxane and calcium carbonate of vaterite phase. The biodegradable fibers may be coated with apatite. When the guided bone regeneration material is immersed in a neutral aqueous solution, silicon species ions are eluted from the calcium carbonate. The guided bone regeneration material excels in bone reconstruction ability.

Abstract

A method for producing an implant whose surface is roughened by the sandblast method using shot material containing fluoroapatite. Fluoroapatite, compared to hydroxyapatite, has poor biocompatibility, but is superior in hardness. It also has a property of being dissolved in acid. As a result, by the sandblast method using shot material containing fluoroapatite, the surface roughening is performed quite effectively, and shot materials remained on the surface can easily be removed by acid.

Abstract

[PROBLEMS] To provide a method of producing an implant which has an excellent rough surface and from which a shot material has been adequately removed. [MEANS FOR SOLVING PROBLEMS] A method of producing an implant wherein the surface is roughened basically by using the sand blast method with the use of a shot material containing fluoroapatite, and so on. Although fluoroapatite is inferior in biological compatibility to hydroxyapatite, it has an excellent hardness. On the other hand, it has a property of being easily soluble in an acid. Therefore, an implant which has an extremely good surface roughness and from which the residual shot material can be easily removed using an acid can be obtained by roughening the surface of the implant by the sand blast method with the use of a shot material containing fluoroapatite.
