Replace种植系统固定修复的近期疗效评估

Early clinical study of Replace Implant System used for the missing tooth

目的:评估Replace种植系统修复不同类型缺失牙的近期临床结果。方法:2005年9月至2008年9月为120例局部缺牙患者成功植入214颗Replace种植体,其中160颗按常规方法植入,54颗为同期或分期应用了GBR技术。4颗行外侧壁径路上颌窦底提升植骨,同期种植体植入。3-6个月后行二期手术,完成上部结构修复。结果:Replace种植体修复后随访3-20个月,1例修复后16个月患种植体周围粘膜炎,经临床治疗得以控制。所有种植体均无松动,并能良好的行使功能至今,种植体累积存活率100%。结论:用Replace种植系统修复不同类型缺失牙临床外科成功率高,修复疗效满意,并发症低,修复设计及手术后初期稳定性是确保前期种植成功的重要因素。

Objective:To evaluate the early clinical effect of Replace Implant System prothesis for the restoration of the different types of missing tooth.Methods:A total of 214 Replace dental implants were consecutively place in 120 partially edentulous patients,including 160 implants by conventional methods placement,and 54 implants with simultaneous GBR(Sept,2005 to Sept,2008).4 implants with maxillary sinus lift and bone graft.The second stage surgery was done after 3-6months and fixed prosthesis was completed.Results:The follow-up time varied between 3 to 42 months.Peri-implant mucositis was diagnosed after 16 month loading and controlled by clinic treatment.All implant fixtures are osseointegrated and functioned well up to now,representing a cumulative survival rate of 100%.Conclusions:Using Replace Implant System to repair missing tooth can achieve high surgery successive rate,satisfactory restoration effects and infrequent complications.The prosthetic design and the initial stability are the key point to insure the earlier period success of dental implant.
