Abstract
The defective areas in the premolar-molar region of maxillary alveolar bone of eight patients were reconstructed using powdered nacre from t he giant oyster Pinctada maxima. Histological, microradiographic and p olarized light studies of drill biopsies taken 6 months postoperativel y showed that nacre was tightly bound to newly-formed bone. The nacre was gradually and centripetally biodissolved and replaced with immatur e and then mature lamellar bone. These results are in agreement with o ur previous experimental in vitro data indicating that nacre has good osteogenic properties.
