ABSTRACT

Objective:To evaluate the effect of segmental approach in the treatment of Angle class Ⅱ division 1 malocclusion.Methods:7 cases of classⅡ,division 1 maloclusion were treated.Upper first premolar and lower second premolars were extracted in all cases.Lower first molars were mesially moved by means of segmental arch. Cephalometric analysis was used to evaluate the effects of the treatment.Results:Facial profile improvement and lower anterior facial height maintenance were achieved.The occlusion plane angle,mandibular plane angle were well controlled with lower anterior teeth upright on the lower basal bone.All patients represented good mandible response.Conclusion:Segmental technique is a simple and effective approach in correcting class Ⅱ,division 1 maloclusion
