Abstract

Implantation of a malleable composite hydroxylapatite/plaster of Paris mixture moistened with calcium hydroxide solution was performed in periapical defects which could not be treated successfully by nonsurgical procedures. A 1.5:1 mixture of sintered hydroxylapatite particles (OrthoMatrix HA-500) and plaster of Paris (USC Medical Grade Calcium Sulfate Hemihydrate B) containing 0.85% K2 SO4 is moistened with Calcium Hydroxide Topical Solution, USP and formed into a malleable mass. This is placed into the surgical defect, shaped and covered with resorbable polyester mesh. The flap is replaced and pressure applied for 5 minutes before suturing. Sutures are removed in I week and x-rays are taken immediately after surgery and at six month intervals. In all types of defects in which the material was employed, the prognosis for postsurgical tooth retention was improved and short term success was 91%. The success achieved suggests that this implantation procedure should receive wider application for complex endodontic periapical osseous defects.
