Many think the probability of success of an oral appliance is inversely related to the severity of OSA. It is common to read here (I have posted it myself) that oral appliances might work for mild to moderate OSA and are very unlikely to work for severe OSA.
Go read this article:
Or this one:Most literature states that oral appliance treatment of OSA should be reserved for mild to moderate cases.1-3 Our findings4,5 are that it is not the severity of OSA that predicts the success of oral appliance treatment, but the site of closure (velopharynx—high, oropharynx—mid, and hypopharynx—low).
................. Oral appliances need not be reserved for mild to moderate OSA cases.

"It's not the severity, it is the anatomy."Mandible advancing oral appliance seems not to be effective in reducing the AHI value in mild cases. However, it seems to be especially effective in reducing the apnea/hypopnea index in moderate and even certain severe OSA patients.

But don't forget, the portion of patients who can effectively be treated by oral appliances seems to be quite low. For now, CPAP remains the number one therapy for the patient population in general.
