Abstract
A 4-year study and evaluation of nonresorbable hydroxylapatite to augment different alveolar ridges has been reported. The technique used resulted in improved contour, height, and width of the alveolar ridge. It was found that denture comfort improved with ridge augmentation as this allowed improved stability, support, and preservation of the ridge. Patient satisfaction was correlated to both surgical and prosthodontic success with the use of hydroxylapatite. The state and health of the tissues were found to be improved with the use of hydroxylapatite or hydroxylapatite and bone marrow. The prosthetic and surgical procedures were found to be easier to perform, and they produced more permanent and superior results than those previously experienced with only bone grafts and other alloplasts.
