种植支抗压低对伸长牙同期种植修复缺失后牙的临床研究

Clinical evaluation of simultaneously restoration for the missing posterior teeth by dental implants after suppressing the opposite elongated teeth with micro-implant anchorage

目的研究种植支抗压低对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牙伸长的成年患者,利用支抗种植钉作为骨支抗,对16颗对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牙和种植义齿均未出现明显的骨吸收。结论种植支抗压低对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 implants 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.
