Zimmer种植系统在下颌磨牙区即刻种植的临床应用

摘要

[目的]评价Zimmer种植体在下颌磨牙区即刻种植的临床效果.[方法]选择67例89颗下颌磨牙区即刻种植病例,均为微创拔牙术后即刻植入Zimmer种植体,其中76颗在种植体和拔牙窝骨壁之间植入Bio-oss Colla-gen并缝合固定以关闭拔牙窝.种植术后3~6个月完成永久修复,临床随访6~24个月.[结果]临床随访期内种植体存留率100%,89颗种植体均达到临床和放射学上的骨结合并成功负载.[结论]Zimmer种植体在下颌磨牙区采用即刻种植并以Bio-oss Collagen关闭种植体和拔牙窝骨壁之间间隙可以获得良好骨结合,缩短患者就诊时间,简化手术程序,获得了理想的治疗效果.%[Objectives]To observe the clinical effects of the immediate implant placement of Zimmer dental implant sys-tem in the mandibular posterior region.[Methods]67 cases with a total of 89 mandible posterior teeth to deal with immediate implantion which selected to be treated with Zimmer dental implant system.76 teeth between implant and tooth socket bone wall were simultaneously filled with Bio-oss Collagen.The upper structure was repaired with PFM porcelain crown after the postoperative phase I of 3~6 months.All the patients were followed up for 6~24 months.[Results]During the clinical follow up,the implant survival rate was 100%. In 67 patients,89 implants was successfully loaded,with stable implants,good condition in synosteosis and without adverse subjective symptoms. All of the 67 patients had achieved good synosteosis and success loads clinically and radiologically.[Conclusion]A good osseointegration is obtained in the mandibular posterior re-gion with Zimmer dental implant system,Correctly dealing with Bio-oss Collagen between implant and tooth socket bone wall.At the same time,it can shorten the time of therapy,simplify the procedure,so that the clinical results are more satis-factory.
