Trauma from occlusion in monkeys

Abstract
Traumatic occlusion was induced in monkeys by insertion of bridges raising the bite. Both incisors and molars were used as abutments. Observation periods ranged from 7 to 24 months. No appreciable effect of the trauma on the apical proliferation of the crevicular epithelium was found. The results were the same in monkeys with or without marginal gingival inflammation before the trauma was induced.
