Abstract
A living hard tissue replacement is prepared by subjecting a calcium phosphate base ceramic material to superplastic forming. Also provided is a method for preparing a composite body comprising the step of joining a cover of a calcium phosphate base ceramic material to a substrate of a heterogeneous material by superplastic forming. Superplastic forming is often performed by hot isostatic pressing. The living hard tissue replacement and composite body are useful as artificial dental roots, dental crowns, and bones.
