Customizing a nasal CPAP mask using a silicone elastomer.

Nasal continuous positive airway pressure (CPAP) is an effective treatment for obstructive sleep apnea (OSA). Airway obstruction is prevented by delivering air at a constant pressure via a nasal mask worn during sleep. Small nares may cause difficulty in wearing even the smallest standard nasal mask, with wear resulting in discomfort and air leaks. This article describes a method for fabricating a custom nasal CPAP mask using maxillofacial prosthodontic laboratory techniques.
