Ten patients received augmentation of deficient mandibular alveolar ridges using particulate hydroxyapatite (HAP). Masticatory ability was evaluated preoperatively and postoperatively by a questionnaire with 35 foods listed and by the spectrophometric method using ATP granules. The results showed that masticatory ability when wearing newly constructed complete dentures was significantly enhanced compared to that when wearing old dentures or relined dentures, and that the surgicalprocedure and the use of the surgical stent greatly improved masticatory ability when wearing the new dentures. The sensitivity of the mucose membrane of the augmented mandibular alveolar ridge was examined during a postoperative period of 24 months by using an electric nerve stimulator. The sensitivity of the mucose membrane decreased postoperatively, especially at the buccal site of themolar region, the so-called buccal shelf. The level of sensitivity increased periodically, and did not return to the average level for normal edentulous mucosa even 24 months after the augmentation. The patients were highly satisfied with the new dentures and the NAP augmentation judging from the questionnaire. From these points of view, HAP augmentation in edentulous patients having severely resorbed alveolar ridges has proved to be benficial in allowing the recovery of masticatory function.
