Description | Case report:- T Mathew * *School Of Dentistry, International Medical University, Bukit Jalil, Kuala Lumpur , Malaysia, 57000.
Abstract:- Introduction: Functional appliance is an effective way of treating skeletal Class II malocclusion in children and adolescents. A 12-month mandibular advancement protocol with Twin Block appliance has been proved to enhance the condylar growth and to improve the mandibular retrognathism. Objective: The case report documented the treatment of a 12- year- old girl with skeletal class II malocclusion with over jet of 8mm, 100% Deep bite and Angle Class II molar, Class II canine and Class II incisor relationship. Method: The phase I Orthopedic stage treatment was done using Twin Block appliance for 12 months with mandibular advancement of 8mm including trimming of inter-occlusal bite plane of the Twin Block to facilitate the eruption of Mandibular molars. This was followed by a phase II Pre-adjusted Edgewise appliance therapy for finishing and detailing. Result: The treatment objective of normal overjet and overbite, skeletal class I by growth modification, class I molar relation, class I canine relation, class I incisor relation and lip competency were achieved. Conclusion: A stable harmonious occlusion was achieved after 20 months of treatment.
Key Words:- Functional appliances. Angle Class II malocclusion. Pre-adjusted Edgewise appliance.
