摘要
目的 :应用Meta 分析法研究国内关于贴面修复的临床应用现状 ,评估 5种类型贴面修复的总体平均成功率。方法 :查阅 1988- 2 0 0 1年国内 13种口腔医学类杂志有关贴面修复的文献 ,根据纳入和排除标准 ,分两步选择适用文献 16篇进行质量评估。对“失败”作了统一的定义 ,作为统一的研究结果。对文献进行了均衡性检测 ,各文献数据合并计算出各型贴面修复的总体平均成功率。结果 :所有文献按 0 - 1标准的平均加权质量分为 0 .6 2± 0 .0 8,各篇文献的质量分分别作为其合并样本量的权数。预成瓷贴面 2篇文献 ,1年成功率 98.3% ,2年成功率97.0 %。烤瓷贴面 5篇文献 ,1～ 2年成功率 97.1%。直接型树脂贴面 5篇文献 ,1年及 2年成功率分别为 96 .7%和 88.6 %。间接型树脂贴面及成品牙片直接粘面法的文献分别为 3篇和 2篇 ,但其数据不能合并 ,因而分别描述。结论 :Meta 分析法是一种综合分析口腔医学同类临床研究的有效方法。预成瓷贴面及烤瓷贴面修复的临床成功率较高 ,树脂贴面 (直接型和间接型 )修复临床成功率随时间增加而降低。成品牙片直接粘面法临床已很少采用。
Objective: Our aim was to make an inventory of clinical studies on veneer restorations (VRs) in China by using a meta analysis review procedure on an overall of results of 5 types of VRs. Methods: From the dental journals in China from 1988 to 2001, papers were selected using an in and ex clusion protocol in a two step procedure. In addition, the 16 papers selected were subjected to a quality assessment. Although not all studies used an identical definition of failure of VRs, this term 'failure' was chosen to be the common study outcome. After a homogeneity test, the mean overall successful rates were calculated by pooling the data from the studies. Results: On a 0-1 scale, the weighed overall mean quality score of the studies was 0.62±0.08. The quality score was used as weight for pooling the samples f studies. From the 2 studies on preformed porcelain VRs, the overall mean successful rates were 98.3% after 1 year and 97.0% after 2 years. And from the 5 studies on porcelain VRs, that was 97.1% after 1 to 2 years. Yet, from the 5 studies on direct resin composite VRs , the rates after 1 year and 2 years were 96.7% and 88.6%, respectively. The data from the 5 studies on indirect resin composite VRs and 2 studies on acrylic veneers could not be pooled. Therefore, these data were described separately. Conclusion: Meta analysis is an effective procedure to review and estimate the dental clinical studies on a same topic. Preformed porcelain VRs and porcelain VRs have higher overall mean successful rates, and that of resin composite VRs (both direct and indirect) decreased with the time. Nowadays, acrylic veneers are scarcely used in clinical practice.
