This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Sleep apnea happens when your airway closes during sleep, stopping your breathing repeatedly. This trial is testing whether a special remotely controlled mandibular positioner (RCMP) — a device that gently moves your lower jaw forward — can predict whether jaw advancement surgery will work well for you. The device helps doctors see how your breathing improves when your jaw is in different positions, which may help them know in advance whether surgery will be successful.
Jaw advancement surgery is one option for people with moderate to severe sleep apnea who can't tolerate other treatments. However, not all patients benefit equally from this surgery. Doctors hope that the RCMP device can act like a 'test run' for surgery, helping predict which patients will have a good outcome and avoiding unnecessary surgery for those who won't benefit.

If you join, you'll first have an exam with an oral surgeon to confirm you're a good candidate for jaw surgery. Then you'll come for a sleep study where the RCMP device gently positions your lower jaw forward in small steps while monitoring your breathing and oxygen levels — this shows how much jaw movement helps you. Finally, you'll undergo standard jaw advancement surgery, and return for a follow-up sleep study 4 to 8 months after surgery to see if the surgery improved your sleep apnea as predicted.
