[Influence of functional therapy on the gingival recession in patients with wedge shaped defects. A 2.5-year longitudinal study of the etiology of periodontal atrophy].

In 20 patients a free way space of greater than or equal to 1.0 mm and a cuspid protected guidance was formed. A previous study has shown, that prematurity and defective contacts reduce the free way space step by step and induce an artificial clenching. The front teeth was relieved in intercuspal position. The increase sof gingival recessions at the upper jaw was over five times significant slighter in treated patients than one in the 22 men of the control group. There was no significant, differences in the lower jaw. The recessions are represented as a sequence of a chronic biomechanical overloading.
