目的 研究种植支抗压低对(牙合)伸长牙同期种植修复缺失后牙的临床效果.方法 8例后牙缺失伴对(牙合)牙伸长的成年患者,利用支抗种植钉作为骨支抗,对16颗对(牙合)伸长牙进行正畸压低矫治,矫治结束前8～12周植入种植体,矫治结束时即刻进行上部结构修复.随访1年,观察临床效果.结果 8例患者16颗伸长对(牙合)牙压低矫治成功,平均压低疗程为7个月,缺失牙种植义齿修复后咀嚼功能正常；1年后随访,压低后的天然牙与种植义齿咬合稳定,X线片显示矫治压低的对(牙合)牙和种植义齿均未出现明显的骨吸收.结论 种植支抗压低对(牙合)伸长牙同期种植修复缺失后牙,缩短了疗程,有利于早期建立稳定的咬合关系,是一种可行的临床治疗选择.%Objective To study the effects of simultaneously restoration for the missing posterior teeth by dental im-plants after suppressing the opposite elongated teeth with micro-implant anchorage. Methods Eight Adult partial edentulous patients needing restoration with elongated opposite teeth were included in this study. 16 teeth were suppressed by micro-implant anchorage, 8 to 12 weeks to insert the dental implants before the end of orthodontics, implants restoration at the time of the end of suppressing, follow-up of 1 year. Results 8 cases had been suppressed successfully after treatment , with the average suppressing treatment of 7 months. The missing teeth were replaced by the regular prosthetic and re-gained the normal mastication function. Within the 1 year revisit period, the occlusion relationship between the orthodontic teeth and the prosthetic was stability and the bone level around the implants and the orthodontic teeth were stable under the X-ray. Conclusion Simultaneously restoration after suppressing elongated teeth by micro-implant anchorage could shorten the course of treatment, and keep the re-buiding occlusion stability, so it is suitable for promotion in clinical practice.
