Dorsal
Dave's Dorsal (DD)
Gergen's own dorsal variant, built to the protrusive position and adjustment range you prescribe.
Snore Guards
Created for comfort — a dual laminate anti-snore appliance, hard outside and soft against the teeth.

Removable · Scan or impression
Scan or impressions, a bite where the design needs one, and a signed prescription. If anything on the Rx is left open, a technician calls your practice before the case is started.
The Original Snore Guard is made with a hard outer shell and a soft inner surface, so the patient gets the durability of a rigid appliance and the comfort of a soft one in the same piece.
The two shells are fused together in the posterior sections with the mandible held in a forward position.

Dorsal
Gergen's own dorsal variant, built to the protrusive position and adjustment range you prescribe.

Dorsal
Two independent arches with acrylic dorsal fins engaging upper ramps, adjusted by screws in the upper acrylic.

TAP
Single-point anterior advancement mechanism supplied to the construction bite you register.
