ABSTRACT:
A method of recapturing an anterior displaced mandibular disc including the steps of moving the mandible to an anterior position from its normal position to increase to the vertical height between the condyle and fossae, retaining the mandible in the anterior position to permit the mandibular disc to become displaced to a more posterior position, and periodically moving the mandible to a more posterior position in increments until it is returned to a permanent position which is anterior of its original normal position, all of the foregoing while providing sufficient clearance between the upper and lower posterior molars to permit eruption therebetween, to thereby maintain an increased vertical height. A functional jaw orthopedic device for recapturing an anterior displaced mandibular disc including a palatal body for fixed placement in the palate area in relation to the upper teeth, a mandibular body for fixed placement in the mandibular area in relation to the lower teeth, an adjustable connection between the mandibular body and the palatal body for providing relative movement in a posterior direction from an underbite position, and a clearance area between the upper and lower molars to permit eruption thereof for increasing the vertical spacing between the maxilla and the mandible in the condyle-fossae area.
