This case report describes a simplified orthodontic system for the management of a palatally impacted canine accompanied by root resorption of incisors. The anchorage for this system is the transpalatal arch and a heavy buccal segment arch wire with two loops soldered to stainless steel bands. This type of stationary anchorage provides stability by uniting both molars across the palatal vault and thus avoids the need for bonding of adjacent mobile teeth. With this system an impacted canine can be extruded, moved distally, jumped over the occlusion, and derotated. The efficiency of this appliance makes it a safe method for moving teeth through simple manipulation and with minimal esthetic inconvenience.
本病例报告描述了一种简化的正畸系统,用于治疗伴有切牙牙根吸收的腭侧阻生尖牙。该系统的支抗是跨腭弓和一根重型颊段弓丝,其上焊接有两个环并固定于不锈钢带环。这种固定式支抗通过横跨腭穹窿连接两颗磨牙来提供稳定性,从而避免了粘结相邻活动牙齿的必要性。使用该系统,阻生尖牙可以被牵引、远中移动、越过咬合平面并扭转。该矫治器的有效性使其成为一种通过简单操作移动牙齿且美观影响最小的安全方法。
