Use of a prefabricated splint for segmental augmentation of the mandibular alveolar ridge with hydroxyapatite

Hydroxyapatite is a biocompatible material for augmentation of edentulous ridges to improve patient comfort and denture stability. The problems associated with hydroxyapatite are generally related to the amount of material introduced and the site of implantation. This article describes the use of a prefabricated splint that permits localization of the implant material to selected sites of the mandible and restricts the amount of material used. Fabrication of this splint under the guidance of the prosthodontist and oral surgeon permits the most effective use of this technique.
