Abstract
An improved method for the production of endosseous implants is disclosed. The method includes thermally spraying a hydroxyapatite-containing powder onto the surface of a metallic core material, and treating the resultant product with an aqueous solution which does not substantially dissolve the hydroxyapatite but can dissolve calcium oxide, to thereby dissolve out alkaline components. The endosseous implants of this invention have excellent mechanical properties and excellent affinity to the living body without hematolysis, and hence, are useful for the treatment or recovery of defective or lost bones, joints and tooth roots.
