This document provides guidelines for other dental professionals regarding restorative treatments, hygiene visits, temporary restorations, and laboratory procedures for patients undergoing Obstructive Sleep Apnea (OSA) treatment with a custom oral appliance. It emphasizes adjustments to maintain appliance fit, minimizing occlusal surface features, assessing for fremitus, and using specific cements for temporary restorations. It also states that the oral appliance must remain in TDSS care for laboratory work and that TDSS exclusively handles adjustments to maintain warranty and effectiveness. Modifications made by other offices may result in patient responsibility for associated fees.
