| 摘 要： | 目的：探讨金属烤瓷修复后修复体颈缘的情况。方法：对55例患者制作65个单位的金属烤瓷修复体，冠边缘位置分别在牙龈上方（21例）、齐牙龈（21例）和牙龈下（23例）。修复完成后2年进行随访，采用牙龈指数、颈缘退缩及颈缘适合性作戴冠前后指标分析。结果：龈上和齐龈肩台组龈炎反应轻，分别有2例和3例；龈下肩台龈炎有6例，龈上肩台与齐龈肩台龈炎差异无统计学意义（P〉0．05），龈下肩台与龈上肩台龈炎比较差异有统计学意义（P〈0．05）。结论：龈上或齐龈肩台设计能较好的避免基牙龈炎。

| Abstract: | Objective: The aim of this article was to evaluate the effects of three tooth preparations of PTM restoration. Methods: This design was assigned into 3 groups according to different gingival margin location. After two year restoration, we randomly analysed gingival index and margin fit. Results:The undergingival margin preparation of tooth has a highest incidence of gingivitis in three groups. 6 gingivitis were found in under-gingival margin. The up-gingival margin has 2 gingivitis. The level-gingival margin has 3 gingivitis. Conclusion: The up-gingival margin and level-gingival of configuration may prevent gingivitis. |
