Estudio retrospectivo del tiempo de erupción de caninos incluidos utilizando dos sistemas de tracción

Abstract

Introduction: temporal osseous anchorage is a recent technique that clinicians have incorporated to orthodontic treatments. The aim of this study was to compare retrospectively the time required to complete the canine forced eruption phase by using two different orthodontic devices. Subjects and methods: a total of 31 patients treated in a private office during the last 15 years were studied. Test group comprised 15 patients on whom traction of the impacted canine was performed with a mini-screw, and control group comprised 16 patients on whom traction of the impacted canine was performed from teeth. Results: in spite of a shorter time of traction detected in the mini-screw group there were no statistically significant differences between groups. Conclusions: in this retrospective comparative study no statistically significant differences could be observed between groups, suggesting that within the limits of this study, forced eruption time does not depend on the traction system.
