Abstract:
Objective To evaluate the craniofacial and occlusional changes of Class Ⅱ patients treated with Tip-Edge Plus technique.Methods Twelve Class Ⅱ patients(7 girls and 5 boys,mean age 14.3 years)with bimaxillary or maxillary protrusion were selected.All the patients were four first premolar extraction cases and treated with Tip-Edge Plus technique.Cephalometric analysis Was performed to evaluate the changes before and after treatment.Results After treatment,the profile Was greally improved.UL-E,LL-E were decreased significantly(P<0.01)and incisors were retracted(P<0.05).Upper molars noved forward slightly(P>0.05).Conclusions The anchorage control in Tip-Edge Plus technique was effective without extraoral force,palatal arch and implants.Under very light force,the crown of anterior teeth tipped distally and lingually quickly.In the final stage,it was possible to achieve both desired root uprighting and crown torque.
