Camlog种植体支持固定和活动修复无牙颌10年临床研究

目的 研究10年观察期内用Camlog种植体修复无牙颌患者的种植体生存率及影响因素.方法 1995至2006年142例无牙颌患者共910颗Camlog种植体分别种植在无牙颌的上颌或下颌.其中376颗种植体（41.32%）做固定修复,534颗种植体（58.68%）做活动修复,观察性别、种植体部位和修复类型对种植成功率的影响.结果 其中17例患者28颗种植体脱落,种植体成功率96.92%,女性患者的种植体成功率略低,但差异无统计学意义（P ＞0.05）.累计的种植体成功率上颌骨为96.98%,略高于下颌骨96.84%,但差异无统计学意义（P ＞0.05）.种植体支持固定修复的10年成功率为98.64%,种植体固位的活动义齿成功率为99.18%,累计的种植体生存率在活动与固定修复之间差异无统计学意义（P ＞0.05）.结论 确认了种植体支持无牙颌患者修复学中长期成功率.种植体固位的活动全口义齿治疗方式在种植体生存率上与种植体支持的固定义齿结果是相同的.

Retrospective study of Camlog implant-supporting fixed and removable prostheses in edentulous patients

Objective To evaluate the fixed and removable Camlog implant-supported prostheses in fully edentulous patients within a functional period. Methods One hundred and forty two patients （57 males and 85 females） with an average age of 61.3 years were treated in Department of Oraland Maxillofacial Surgery, Charit e Hospital from 1995 to 2006. A total of 910 Camlog implant were placed in the edentulous maxilla, mandible or both jaws to allow a prosthetic rehabilitation with fixed （380 implants, 41.87%） or removable （530 implants, 58.13%）implant-retained prostheses. The survival rate of the implants was evaluated according to gender, implant location and type of prostheses. Results Seventeen patients lost a total of 28 implants with a cumulative implant survival rate of 96.92%. There were no significant differences in the cumulative implant survival rate between maxilla （96.98%） and mandible （96.84%） （P 〉0.05）. The 10-year cumulative survival rate of implants after rehabilitation for fixed restoration was 98.64% and for removable implant-retained overdenture was 99.18% （P 〉0.05）. Conclusion This retrospective study confirms good clinical outcome of implant-supported treatment for the rehabilitation of totally eclentulous patients, and also shows a successful application of Camlog implants to support two types of prosthetic rehabilitation.
