Abstract

Treatment time and mechanics required to solve palatally impacted canines are usually challenging. Different biomechanics and protocol approaches are available, and among these, the use of skeletal anchorage as reactive unit can be noteworthy. The purpose of this article is to show a treatment of a palatally impacted canine by the means of a double miniscrew and cantilever system only. Two miniscrews with bracket heads were applied in a 16 years old patient; different cantilevers were used to solve the impaction and bring the canine in the right position. Results: the impacted canine was successfully moved into proper position with good three-dimensional control. Both miniscrews worked successfully as anchorage for the entire treatment. The palatally impacted canine was successfully treated utilizing two miniscrews and cantilever approach.

摘要

治疗腭侧埋伏阻生的尖牙通常具有挑战性,需要花费时间并运用一定的力学原理。目前有不同的生物力学和方案可供选择,其中,将骨骼锚固作为反应单元可能具有重要意义。本文旨在介绍一种仅使用双微螺钉和悬臂系统治疗腭侧埋伏阻生尖牙的方法。在一名 16 岁的患者中应用了带有托槽的两颗微螺钉;使用不同的悬臂来解决阻生问题并将尖牙移动到正确的位置。结果:成功地将埋伏的尖牙移动到合适的位置,并实现了良好的三维控制。两颗微螺钉均成功地作为整个治疗过程中的锚固。使用双微螺钉和悬臂方法成功地治疗了腭侧埋伏阻生的尖牙。
