Abstract

A model of severely atrophic mandible is modified with wax to a desired postoperative ridge form. An extended surgical splint is produced from clear acrylic resin.<BR>After completion of the subperiosteal tunnel dissection, the surgical splint is fixed to the mandible with circummandibular ligatures. Hydroxyapatite particles are injected into the tunnel.<BR>This method can prevent migration of hydroxyapatite particles and reduce extension of the alveolar ridge.
