Mandibular advancement device

A mandibular advancement device having a first frame and a second frame, the first frame having a first occlusal surface and generally a U shape, the U shape having an apex and two ends, the two ends associated with a rear of the first frame and the apex associated generally with a front of the first frame, a second frame having a second occlusal surface, the mandibular advancement device comprising:

• a first rib of the first frame, the first rib having a narrower portion and a wider portion;
• a first upstanding sidewall on the first occlusal surface of the first frame;
• a first inner surface of the first upstanding sidewall, the first upstanding sidewall extending lengthwise in a direction from the rear towards the front;
• a first channel of the second frame, the first channel in relative position to interface with the first rib;
• a second upstanding sidewall on the second occlusal surface of the second frame;
• a first outside wall of the second upstanding sidewall, the outside wall in relative position to interface with the first inner surface of the upstanding first sidewall;
• and
• wherein the first frame and the second frame are configured to be disposed in a first position and a second position wherein, in the first position, the first rib is outside of the first channel and wherein, in the second position, the first rib is disposed in the first channel and the first inner surface of the first upstanding sidewall is adjacent the first outside surface of the second upstanding sidewall, and wherein, upon squeezing the first frame and the second frame together, the first rib of the first frame snaps into the first channel thereby holding the first frame and the second frame together.

A mandibular advancement device having a first frame and a second frame, the first frame having a first occlusal surface and generally a U shape, the U shape having an apex and two ends, the two ends associated with a rear of the first frame and the apex associated generally with a front of the first frame, a second frame having a second occlusal surface, the mandibular advancement device comprising:

• a first set of upstanding sidewalls on the first occlusal surface of the first frame, the first set of upstanding sidewalls extending lengthwise in a direction from the rear towards the front;
• a first locking member of first set of upstanding sidewalls;
• a second set of upstanding sidewalls on the first occlusal surface of the first frame;
• a second locking member of the second set of upstanding sidewalls;
• a first mating locking member on the second frame, the first mating locking member dimensioned in relative proportions and disposed in relative position to receive the first locking member;
• a second mating locking member on the second frame, the second mating locking member dimensioned in relative proportions and disposed in relative position to receive the second locking member;
• and
• wherein the first frame and the second frame are configured to be disposed in a first position and a second position wherein, in the first position, the first and second frames are apart and wherein, in the second position, the first locking member is disposed in the first mating locking member and the second locking member is disposed in the second mating locking member, and wherein, upon squeezing the first frame and the second frame together, the first locking member snaps into the first mating locking member of and the second locking member snaps into the second mating locking member thereby holding the first frame and the second frame together.
