[Substitution of the dental root by aquatic invertebrate skeletons in animals and man].

The biocompatibility of mammal bone with aragonite and calcite skeletons of aquatic invertebrates (Corals, Molluscs) led us, after animal experimentation, to implant in humans artificial dental roots derived from such invertebrates. These roots, incorporated but not resorbed, serve as supports for a prosthetic crown; they are equipped to isolate the root from the buccal cavity and to ensure shock absorbtion during mastication. The greater ease of implanting artificial teeth and their excellent acceptance will in many cases modify the strategy of current dental treatment.
