This appliance is designed to blend the best of all the previous appliances (ON1 & On2). It has a circular ramp to hold the mandible forward. This may be necessary for the patient who locks in the supine position. It also maintains the airway, both oropharyngeal and nasopharyngeal. The round hole allows air to pass for the oropharyngeal airway and allows the tongue to rest in it that improves nasal breathing. It has an anterior pad with no posterior occlusion. This also acts as an Anterior Deprogrammer to reduce parafunctional activity.
Specifications
The phonetic position is used when the airway is within normal ranges, when the phonetic position corrects to normal or when no mandibular position would improve the airway. These determinations are made using Ecovision (acoustic pharyngometry). If you do not own or have access to a pharyngometer then it is best to use the phonetic position.
Who Should Wear This Appliance
This appliance is universal. It can be used with patients who have inflammation of the joint capsule (capsulitis), lock in the supine position, have airway obstruction, clench or grind their teeth or any combination of the above. The ON2 (ramp) blocks airway and is contraindicated in patients with obstructed nasal breathing.
