Introduction of a surgical insult in conjunction with orthodontic therapy has been shown to accelerate treatment in minor tooth movement and comprehensive orthodontic cases by induction of the regional acceleratory phenomenon (RAP). When applying this concept to a molar tipped into an adjacent edentulous site, a dental implant can be planned to anchor the movement.
A generally and periodontally healthy 25-year-old patient presented missing tooth #19, with tooth #18 mesially tipped into the first molar crown space. A dental implant was placed in the #19 position. Following osseointegration, the implant anchored orthodontic movement of the adjacent tooth, which was initiated in conjunction with third molar extraction.
Favorable biomechanics for molar uprighting can be achieved using an osseointegrated implant and a customized orthodontic device. The presented technique facilitates implant site development without delaying placement of the fixture and simplifies fabrication of a harmonious and anatomic implant-supported restoration. Induction of the RAP may hasten treatment completion.
在正畸治疗中引入外科创伤已被证明可以通过诱导区域加速现象（RAP）来加速小范围牙齿移动和全面正畸病例的治疗。当将这一概念应用于倾斜到相邻缺牙部位的磨牙时，可以计划种植体来固定运动。
一位一般情况和牙周健康的 25 岁患者，缺失 19 号牙，18 号牙向近中倾斜进入第一磨牙冠间隙。在 19 号位置植入一颗牙种植体。在骨整合后，种植体固定了相邻牙齿的正畸移动，这是与第三磨牙拔除同时开始的。
使用骨整合种植体和定制的正畸装置可以实现磨牙直立的有利生物力学。所介绍的技术有利于在不延迟固定器放置的情况下进行种植体部位的开发，并简化了和谐和解剖学种植体支持修复体的制作。RAP 的诱导可能会加速治疗的完成。
