摘要:
Implants for bones, joints or tooth roots having sufficient mechanical strength, excellent compatibility with living tissues and other advantageous properties can be obtained by thermally spraying a mixture of ceramics and hydroxyapatite onto a shaped core which is made of ceramics, thereby forming a coating layer of the mixture around the surface of the core.
