An experimental study of the effect of Bite Jumping Appliance in Macaca irus monkey

Abstract

I investigated the effects of a bite jumping appliance (BJA) on growing Macaca irus monkeys. The sample consisted of three monkeys, one of which was a control. Study casts and cephalometric analysis showed that after 32 weeks of active treatment, the experimental animals both had a full Class m relation in the buccal segments. The Class m relation remained during the post treatment period. Histological findings showed that growth of the post glenoid spine was different from normal growth. These results suggest that the BJA is effective for treatment of skeletal Class II malocclusions.
