Abstract
Objective To evaluate the effect of the T4K appliance on the maxillofacical function and structure of children with Class Ⅱ division 1 malocclusion during the growth period,and to provide thetheoretical and practical evidence for the clinical application.Methods Totally 20 children with Class Ⅱ division 1 malocclusion were clinically corrected with T4K appliance;20 cases with the same deformity who refused to receive any treatment were include as controls.The effect of T4K appliance was analyzed through cephalometric radiography.Results After T4K treatment,the patients' profiles were much improved.The findings indicated that SNB,L1-MP,S-Go and N-Me were increased significantly compared with those in the control group,but ANB,U1-SN,overjet and overbite were reduced obviously,the differences being statically significant (P < 0.05).Conclusion T4K appliance can lead to an improvement of facial profile through treatment for Class Ⅱ division 1 malocclusion;however,part of the effect come from the natural growth and development.Therefore,when T4K applicance is used for early orthodontic freatment for children with Class Ⅱ divesion 1 malocclusion,the potential of natural growth and development should be taken into account in order to achieve more effective results while doing less.关键词
