Abstract
A mandible repositioning appliance formed by an upper bite block and a lower bite block interconnected by an adjustable mechanism including a posterior section connected to the rear portion of the upper bite block and an anterior section connected to the front portion of the lower bite block and an adjustable interconnection between the anterior and posterior sections. Preferably the adjustable interconnection will include a double thread element rotation of which changes the relative positions of the posterior and interior sections axially of the appliance and abutments to define each incremental rotation of the element. The comfort of the wearer is further improved by using a heat sensitive material in the tooth retention sections and by permitting limited relative lateral movement between the bite blocks.
