Abstract:
OBJECTIVETo evaluate the effects of modified Forsus appliance in the treatment of Class II mandibular retrusion.
METHODS18 children with mandibular retrusion were selected and treated with modified Forsus appliance. Cephalometric radiographs were taken and analyzed at pre-treatment and post-treatment. Students' t-test was used to determine if there were significant differences between pre-treatment and post-treatment.
RESULTSAfter 6-8 months of therapy, profiles were obviously improved. B moved forward (2.9+/-3.1) mm. ANB decreased (2.5+/-1.2) degrees. The overjet decreased (5.0+2.8) mm. The molar relationship was corrected to Class I from Class II. SN-OL increased (4.3+2.2) degrees. There was significant difference between pre-treatment and post-treatment.
CONCLUSIONCombined with straight wire appliance, modified Forsus appliance can effectively stimulate the mandibular growth, balance the jaw relationship, and correct mandibular retrusion.
