[Roller driver in the treatment of lower jaw deviation after resection]

The unilateral resection of the lower jaw results into displacement of the fragment preserved. Usually a driving device of the lower jaw is worked out for the treatment of the deviation that slides along the vestibular surfaces of the upper lateral teeth and restricts the articular disturbances. The authors task is to determine clinically the harmful forces of friction, proposing, at the same time, an original roller driver for their reduction.
