Abstract
Materials and dental procedures are disclosed for the treatment of resorbed or diseased periodontal and alveolar bone tissues. Biocompatible nonresorbable ceramic mixtures and compounds containing silicon, calcium, phosphorous, and sodium oxides and flurides are prepared as powders or spheres and applied to defects or areas where it is desired to recontour the bone structure. This technique permits an improved method for corrective peridontal procedures and for alveolar ridge augmentation.
