[The use of hydroxyapatite in modern dentistry].

Abstract

Certain patients who show different kinds of clinical situations such as partial resorption of alveolar ridge, periodontal defect and loss of teeth, the ceramic hydroxylapatite is used in three manners: alone, in combination with surgical vitalium in some cases and in others with alúmina, in order to solve these problems. These procedures will give a better rehabilitated solution to the patients. Two types of surgical procedures are used to implant the hydroxylapatite, the subperiosteal tunneling in some cases and the flap procedure in others. The patients are examined by means of clinical and radiographic analyses for about eight years.
