Sleep apnea prosthesis for dentate patients.

This article describes clinical and laboratory techniques for the fabrication of a sleep apnea prosthesis for a dentate patient. The treatment objective is to posture the mandible at an increased vertical and protrusive position to diminish or eliminate the collapse of the base of tongue into the oropharynx. During fabrication of the prosthesis, cephalograms are used to evaluate spatial change between the base of the tongue and the posterior pharyngeal wall.

Stabilized record base for maxillary removable partial denture obturator.

Accurate maxillomandibular jaw relation records are enhanced by a stabilized framework used to support the occlusal rim and recording medium. Stability of the framework is often lost on the defect side because of the size of the surgical defect and/or number of missing teeth. This article introduces a technique that uses a record base stabilized with a soft resilient material that permits easy removal and replacement of the framework on the altered master cast without damage.
