Electromyographic investigation of chin cup therapy in Class III malocclusion
EMG Skeletal Class III Anterior crossbite Chin cup
2009/1/8
Electromyographic activity was evaluated in 20 patients (10 girls and 10 boys, mean age 10 years) with Class III malocclusion who were treated with a chin cup appliance. The posttreatment data wer...
Mandibular morphology in subjects with Class III malocclusions：Finite-element morphometry
Class III Finite element Mandible Morphology Morphometry
