Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review

Abstract

Introduction: The goals of orthodontic treatment are correcting the malocclusion especially bilateral constriction of upper and lower arch, achieving good occlusion and also improve the esthetic. Case report: This case report described the treatment of class I malocclusion with bilateral arch constriction. The 33-year-old female patient presented with class I malocclusion, mesofacial, retrognathic chin, convex profile, and bilateral constriction of both arch. She was treated by pre-adjusted appliances and no teeth was extracted. The upper arch had 2 phases treatment, segmental method and continuous method to correct the constriction. After 18 months of treatment, the malocclusion was corrected with successful aesthetic improvement, class I canine and molar relationship in the left and right side, and also ideal overjet and overbite. Conclusion: Treatment for bilateral arch constriction could be corrected by pre-adjusted appliances. An accurate examination will result in a proper diagnosis and an effective and efficient treatment plan. However, expansion for bilateral arch constriction should consider the limits of expansion because excessive expansion leads to instability.
