The purpose of this retrospective study was to review and assess the outcomes of subjects treated with dental implants at the University of Washington Graduate Prosthodontic Program from 1988 to 2000.
A retrospective review and an outcomes assessment were conducted of patients treated with osseointegrated implants between 1988 and 2000 at the University of Washington Graduate Prosthodontic Program. Patients were treated by graduate students. All included patients had a prosthesis that had been in service for at least 5 years. Implants and prostheses were assessed by chart review, phone survey, and clinical review. Clinical review consisted of mobility testing, soft tissue evaluation, and occlusal evaluation. Specific success criteria were used and life table analyses of implants and prostheses were performed.
Of a total of 114 patients treated, 69 subjects (60.5% of those treated) participated in the assessment; 103 prostheses supported by 273 implants were reviewed clinically. The estimated cumulative survival rate was 96.3% for all implants and 85.4% for all prostheses.
A retrospective review of 69 subjects who were treated in the University of Washington Graduate Prosthodontic Program between the years 1988 and 2000 showed an implant survival rate of 96.3% and a prosthesis survival rate of 85.4%. Prostheses showed higher failure rates than implants.
本回顾性研究的目的是评估和回顾 1988 年至 2000 年在华盛顿大学研究生修复课程接受牙种植体治疗的患者的结果。
对 1988 年至 2000 年在华盛顿大学研究生修复课程接受骨整合种植体治疗的患者进行回顾性研究和结果评估。患者由研究生治疗。所有纳入的患者均有已使用至少 5 年的修复体。通过病历回顾、电话调查和临床检查评估种植体和修复体。临床检查包括移动性测试、软组织评估和咬合评估。使用了特定的成功标准，并对种植体和修复体进行了寿命表分析。
在总共治疗的 114 名患者中，有 69 名患者（治疗患者的 60.5%）参与了评估；对 273 个种植体支持的 103 个修复体进行了临床评估。所有种植体的估计累积存活率为 96.3%，所有修复体的存活率为 85.4%。
对 1988 年至 2000 年期间在华盛顿大学研究生修复课程接受治疗的 69 名患者进行回顾性评估显示，种植体的存活率为 96.3%，修复体的存活率为 85.4%。修复体的失败率高于种植体。
