| Introduction: The aim of this study was to determine the rate of eruption of impacted canines treated with the palatal fenestration technique, and if there is a relationship between the rate of eruption and the initial inclination of the canine. Methodology: The sample consisted of 19 canines from patients of the orthodontic clinic at the Autonomous University of Yucatan (UADY). In order to determine the position of the canines (buccal or palatal), occlusal x-rays were taken. Panoramic x-rays were taken for vertical (from the tip of the cusp to the occlusal plane) and angular measurement (longitudinal axis of the canine with intermaxillary suture) of the impacted canines. Results: The first 4 months after surgery, the canines moved 4.30 mm and the following 4 months 2.31 ??mm on average. This difference could be due to after surgery, the tooth had no bone restrictions and a free guide. It was found that greater the initial inclination was less the number of millimeters that the canines were displaced during the 8 months of the study. Conclusions: The rate of eruption of the canines was higher during the first 4 months after surgery and it was followed by a slowdown in the second quarter. It is expected that when there is higher initial inclination, there is less displacement during the first 8 months, which produces a longer treatment time in these cases. |
