摘要
目的:比较不同排龈取模技术对固定修复模型质量效果的影响。方法:在对门诊金属烤瓷全冠修复患者107例144颗牙中,随机分为3组,分别采用不同排龈取模技术,制取印模,完成修复体。对排龈止血效果、牙预备体肩台、模型清晰程度进行评价。结果:备牙前排龈组与备牙后排龈组的牙体预备有显著性差异,备牙前排龈组印模质量明显高于备牙后排龈组。结论:正确应用排龈技术可减少牙体预备对牙龈组织的损伤及出血,能帮助取得清晰的印模。
Objective： To compare the effectiveness of three gingival distraction methods in fixed prosthetics procedure. Methods： 144 teeth from 107 patients were divided into three groups randomly for porcelain-fused-metal crowns, different gingival distraction methods were applied in different groups, impressions were taken. The effectiveness of gingiva-prepara- tion, bleeding, shoulder shape and sharpness of cast were compared among the three gingival preparation groups. Results： Gingiva retraction group has shown significantly better quality of teeth preparation than group without gingival retraction. Conclusion： The application of gingival retraction can prevent the gingival trauma and bleeding during teeth preparation for fixed prosthetics, and help to make accurate impression.
