Abstract: The aim of this study was to compare the quantity of tooth movement in canine distalization, using the precision technique in the experimental group and the conventional method in the control group. MATERIALS AND METHODS: twenty upper canines of ten patients were analyzed in a split-mouth design. They were distalized using an elastomeric chain applying a force of 250 grams per side. The teeth were divided randomly into two groups; the experimental group: 10 canines in which piezocision were applied; control group: 10 canines distalized with a conventional method. Patients were cited for measurements and changes of elastomeric chains every fourteen days on three occasions. Dental casts were taken at every appointment to calculate the distance of distalization. RESULTS: distalization time in the experimental group decreased since the control group reported a mean of distalization of 0.97±0.32 mm while the experimental group had a mean of 2.01±0. 51mm. CONCLUSIONS: Piezosicion-assisted distalization accelerates tooth movement, decreases loss of posterior anchorage, and is a minimally invasive procedure with a low post-operatory pain level.
