For complex implant cases, simple implantation could not achieve the desired therapeutic effect, and a multidisciplinary approach has become a general trend. Orthodontic treatment before implantation creates favorable conditions for subsequent implantation by increasing restoring three-dimensional space, improving occlusion of patients. It also stimulates the increase of autologous soft and hard tissue while biological potential of periodontal ligament is fully developed. The choice of operation time is vital to keep the level of soft and hard tissue at the implantation site, which improves the curative effect of implantation in terms of function and aesthetics. In this article, the orthodontic-implant combined therapy is briefly reviewed focusing on the three-dimensional space optimization, implant site enhancement by orthodontic extrusion and delayed orthodontic space opening.
面对复杂的种植病例，单纯的种植术已不能达到理想的治疗目的，各学科联合治疗成为一种趋势。种植前辅助正畸治疗可以为种植修复开辟理想的三维空间，改善患者的咬合关系；充分发挥牙周韧带的生物学潜力，利用正畸牵引刺激自体软硬组织增量；选择适宜时机启动正畸治疗，最大限度地维持种植位点的软硬组织水平，为种植手术及后期修复创造良好条件，进而在功能、美学等方面均可优化种植修复的疗效。本文从种植位点的空间优化、软硬组织增量及种植修复时机选择等方面对种植前辅助正畸治疗进行了综述。
