[Case reports of orthodontic treatment related to facial patterns].
This present paper describes 3 clinical cases which were treated according to facial patterns. First, facial pattern of each patient was classified by Ricketts's analysis and then, treatment objects and mechanics were determinded. Brachyfacial patterns are showed a resistant to mandibular rotation during treatment can accept a more prutrusion denture and primary treatment by nonextraction, whereas dolichofacial patterns were tended to open during treatment require a more retracted denture in order to assure post-treatment stability. Brachyfacial pattern would better treat to use extrusive force system, whereas dolichofacial pattern treat to use intrusive force system with head gear and intermaxillary elastics.
