[Coral and cranio-maxillofacial surgery. Results of an experimental study on sheep]

Goniopora Lobata and Polyphyllia Talpina are tested on ten sheep with a follow up of 12 months. The material of reference is a glassceramic CAP 42. Different implantation sides are used: craniofacial and orthopedic. A macro and microscopic postoperative study is performed at 3, 6, 9 and 12 months. The results show: a perfect biocompatibility; a disappearance without colonisation of Goniopora Lobata associated with a complete bone regeneration at 12 months; a later resorption of Polyphyllia Talpina with a fibrous colonisation without osseous transformation. Perspective of using in cranio-maxillo-facial surgery are exposed.
