Apnea Guard is a temporary oral appliance that provides outcomes equivalent to a custom appliance for obstructive sleep apnea treatment. It is fitted with the assistance of any trained healthcare staff in less than 15 minutes and worn for up to 30 nights. The Apnea Guard allows easy determination of an efficacious jaw position that can be prescribed and transferred to the custom appliance, similar to establishing a pressure setting for CPAP. The Apnea Guard Protocols educate both dental and non-dental staff on various aspects of oral appliance therapy. The Protocols provide information used to determine when a patient can fit themselves with assistance of non-dental staff, or when they have a pre-existing condition that requires fitting by a dentist. Tools are provided to help distinguish between expected side effects and complications which may require a consultation.
