title: [Soldering without transition (osteoassimilation) between the human maxillary bone and a compact dental implant in natural calcite from marine invertebrate].
abstract: We present evidence for the formation of woven bone between human maxillary lamellar bone (the target site) and a coral implant (Corallium johnsoni Gray). This newly formed bone is characterized by numerous osteocytes located in spherical lacunae and having many ramified processes directed towards the coral; some of these processes continue into the implant surface. Healthy osteocytes were detected within the superficial part of the coral, next to the newly formed bone. Neither osteoclast nor surface of resorption has been noticed. All these observations indicate tight welding or osteoassimilation without any transition between the maxillary bone and the graft. We have obtained analogous results by using grafts of molluscan mother-of-pearl. Our results differ from those reported by other authors, probably due to the compactness of the biomaterial used here.
