Abstract
An artifical tooth comprises a contacting member formed of a composite material having compatibility with living tissues and diaposed at an outer portion of the artificial tooth to be contacted with alveolar bone, a metal base member having an opening therein and disposed inside of and attached to the contacting member, a metal post inserted into the opening of the metal base member and at least two elastic buffer members disposed in a space between the metal base member and the metal post. The composite material having compatibility with living tissues contains 40 to 95% by weight of a calcium phosphate compound and 60 to 5% by weight of an organic polymer. Each of the elastic buffer members is spaced apart for movably receiving the metal post by which pressure imposed upon the artificial tooth is transmitted.
