Sleep Appliances and Snore Guards
TAP Plus is also a custom-made appliance that is made of a heat-sensitive acrylic that has a separate upper and lower portion that is connected in the front of the device by a hook and bar assembly. This device is comfortable on the teeth and allows good freedom of movement of the jaw. Therefore it is used frequently for patients who tend to grind their teeth heavily. Since the position of the jaw can be adjusted while the appliance is in place, it is also used for patients who have a certain jaw structure that would require that feature. As mentioned the front assembly is located near the tip of the tongue and it protrudes between the lips, so it may take a little bit more time to adapt to the device. However, most patients find it to be comfortable within the first 5-10 days.
The E.M.A. is the thinnest and least bulky of all the appliances. It is similar to clear acrylic orthodontic retainers, and the 'hardware' (located to the cheek side of the molar teeth) consists of specially designed, patented elastic bands. This appliance moves the jaw forward in fairly significant steps, which may be difficult to tolerate. Some care must be taken to avoid breaking the lower portion when replacing the custom elastics. The EMA is well tolerated by patients who grind their teeth. It has no metal and can be used by patients with a nickel metal allergy.
