Evaluation of anchorage loss of the upper first molar using two different retraction methods: A randomized clinical trial

Objective: the aim of the present study was to evaluate the anchorage loss of the molar using two different retraction methods. Subjects and methods: The current randomized controlled clinicaltrials were conducted on a total sample of 10 orthodontic patients (3 males and 7 females), a split- mouth design was performed. Two main groups, which group I included a procedure of canine retraction by using sectional arch in the conventional level of the brackets and tubes, while group II included a procedure of canine retraction through sectional arch in high position utilizing power arms attached to canine and molar tubes. A cone beam computed tomography had been used as observational method. Results: The results showed a significant increase in the anchorage loss in both of the groups, however no significant statistical difference between the two groups.Conclusion: It concluded that both techniques seem to have loss in the anchorage, however comparing both groups with each other's seems to show no significant differences
