Silent Nite® sl positions the lower jaw forward using special S-shaped connectors that are attached to upper and lower trays. These trays are comprised of a soft inner layer with a hard outer layer that is durable and BPA-free. Special Slide-Link connectors are attached to transparent flexible upper and lower forms. The forms are custom laminated with heat and pressure to the dentist's model of the mouth. The new, improved connectors are stronger than those found on the original Silent Nite and are easily interchangeable by the patient. The fit is excellent and comfortable, permitting small movements of the jaw (TMJ) and allowing uninhibited oral breathing. This intra-oral appliance is indicated for patients with a minimum of eight teeth per jaw and a body mass index (BMI) of 30 or less.
To determine the patient's starting anteriorization, a bite registration should be taken using the sl-protrusion gauge. The sl-protrusion gauge is designed to directly register the appropriate mandibular advancement
(protrusion) for the patient receiving the Silent Nite sl. The elastic framework adapts to the bending
of the bite plane and is intended to provide easy removal of the vinylpolysiloxane registration material
afterward. Bending the gauge should not affect the accuracy of the registration, which helps to ensure
a clinically precise result. If for any reason proper registration is unattainable, the Silent Nite sl can also
be manufactured on occluding models.
