单个牙缺失种植修复的两年临床评价

2-year Clinical Evaluation of Single-tooth Implants.

目的 通过两年临床研究对单个牙缺失种植修复的效果进行评价 ,初步分析可能影响种植修复成功率的因素。方法 对 1 996年 3月～ 1 999年 3月期间修复单个牙缺失而植入的 85个DICI种植体随访观察 2年 ,检查其菌斑指数 (PI)、龈沟出血指数 (SBI)、探诊深度 (PD) ,通过X线了解种植体周围骨组织的高度变化。分析不同年龄、性别及种植体所在颌位对种植体修复成功率的影响。结果 85个种植体国 ,失败 1 1个 ,累积成功率 87.1 %。不同年龄、性别及颌位的种植体修复成功率无显著性差异。PI、SBI及PD均值 2年中明显增加。结论 年龄、性别及种植体所在颌位不能影响种植修复的成功率。

Objective To study effect of single-tooth implant through two years clinical evaluation and analyse factors affecting single-tooth implant success. Methods There were 85 implants placed in 78 patients with a mean age 36.3±0.8. The observation period ranged from baseline to 2 years. The measurement included plaque index?probing depth?sulcus bleeding index?periimplant bone height and cumulative success rate. Results 11 of 85 implants failed during two years, giving a cumulative success rate for implants of 87.1%. Means of PI?SBI and PD increase obviously. Conclusion Age?gender and jaw site do not affect implant cumulative success rate. Plaque is main factor of implants failure.
