Open Splint를 이용한 Hydorxylapatite 하악 치조제 증강술

Hydroxylapatite mandibular ridge angmentation using open splint

Progressive residual ridge resorption following loss of the natural dentition produces clinical problems in the denture. Vestibuloplasty, lowering of the mouth floor, bone grafting, osteotomy method, osseointegrated implants, and hydroxylatpatite implantation are generally accepted as the reconstructive methods of the alveolar ridge. Nowadays osseointegrated implant technique has been widely spreaded, but ridge augmentation using hydroxylapatite can be a good candidate if the ridge condition of the patient, economic situation and his preference are considered. But technical difficulties in confining the hydroxylapatite particles into the desired ridge form and shape, and in preventing migration of the particles are commonly experienced. So we represent a somewhat modified method of surgical incision using the open splint technique that obviates the need of vestibuloplasty and lowering of mouth floor.
