  • Patent number: 5277203
    Abstract: A bite plate is provided to protect a user's teeth from damage due to teeth grinding and/or long term interdigitating pressure, as during cervical traction. The device defines a trench for receiving at least some of the upper teeth of a user and is self fitting to accommodate both narrow and wide dental arches. Once inserted into the mouth the device snugly engages the front teeth and remains positioned, keeping the teeth of the upper and lower jaws from directly engaging and being damaged.

  • Patent number: 5277202
    Abstract: A dental orthosis is provided for use in the treatment of snoring. The upper portion of the device defines a trough for receiving some of the upper teeth of the patient. The rear wall of the trough is truncated so that the device can accommodate both narrow and wide dental arches so that one size of the device can accommodate substantially all users. Once inserted into the mouth the device snugly engages the upper teeth, particularly the front teeth, and remains positioned independent of natural motions of the lower jaw. The lower portion of the device is formed into a ramp structure whereby natural jaw motions result in the engagement of the lower teeth with the ramp, which will cam the lower jaw into a more forward position.
