A treatment option for snoring and mild to moderate obstructive sleep apnea, most oral appliances work by supporting the jaw in a forward position to help maintain an open upper airway during sleep. Qualified dentists work with sleep physicians to develop custom-made oral appliances.
According to the American Academy of Dental Sleep Medicine, oral appliance therapy is covered by many medical insurance plans.
This guide compares oral appliances side-by-side on parameters including warranty, materials, PDAC verification, how it works, fitting, adjustment, and supporting study.

How Does the Oral Appliance Work? | FlexTAP advances the lower jaw with a single point midline advancement. Self-titratable adjustments in 1/3 mm increments aid in easier, faster, and better treatment outcomes. | Uses Frantz Design Patent Elastic Mandibular Advancement straps that have been used to treat mild to moderate sleep apnea for over 25 years to position the jaw forward while managing comfort and durability with biocompatible nylon. | The Oasys Simplicity provides mandibular advancement. The standard Oasys with Nasal Dilators improves nasal breathing and adding Tongue Lifters improves forward tongue positioning. | Protrudes the mandible forward to open the airway. | Mandibular position is set to open the airway and hold this position while sleeping. | For OSA, advances the tongue and mandible forward opening the airway. For sleep-related bruxism, the patented forward bite reduces or eliminates the sleep-related bruxism as well as the associated increases in heart rate, blood pressure, and cardiovascular risk. | O2Vent Optima has two mechanisms of action that add stability to the airway. 1. A mechanism of advancing the jaw forward encouraging a more open airway. 2. Incorporates an airway channel that further stabilizes the airway. | O2Vent Optima has two mechanisms of action that add stability to the airway. 1. A mechanism of advancing the jaw forward encouraging a more open airway. 2. Incorporates an airway channel that further stabilizes the airway. | Traction appliance design, in line with the occlusal plane, promoting nasal breathing, minimizing stress on the TMJ and allowing more space for the tongue. A single set of upper and lower splints are connected through a patented rod titration system. | Low profile and lightweight dorsal fin appliance. Maximizes tongue space and avoids soft tissue contact. A single set of durable upper and lower splints are adjusted using an interchangeable clip system. | ProSomnus EVO uses vertically mated buccal posts to advance and hold the mandible forward to open the airway. | The ProSomnus [PH] uses a continuous advancement protocol. Upper arch connects via Herbst Arm to lower arch with an adjustment nut. | ProSomnus EVO SELECT uses vertically mated buccal posts to advance and hold the mandible forward to open the airway. | The airway is kept open by protrusion of the mandible with a 2-part appliance. It allows for lateral movement and mouth opening. | Incorporates a vertical opening and makes more room for the tongue. Also stimulates your brain to naturally migrate the tongue forward during sleep. | The device functions as a mandibular repositioner, which acts to increase the patient’s pharyngeal space during sleep. | A 2-piece, adjustable mandibular advancement device with a connector on each side, it repositions the lower jaw forward and so prevents collapse of the upper airway. | ||||
