摘要:
目的 对排龈线联合止血剂在前牙美容修复龈下肩台的清晰度进行评价，为临床制取清晰的印模及模型提供参考。 方法 选择2013年10月-2014年10月在解放军81 医院口腔科就诊的行前牙美容修复患者68例（188颗基牙），随机分为对照组（83颗）和观察组（105颗），对照组应用双线排龈法，观察组应用排龈线联合止血剂法。排龈后制取 印模，灌注超硬石膏模型。对基牙的肩台、龈沟止血效果、石膏模型清晰程度进行综合评价。 结果 排龈线联合止血剂组与双线排龈组比较，基牙肩台的清晰度、工作模型肩台及 软硬组织界限的优良率差异均无统计学意义（P＞0.05）；而牙龈止血效果优良率差异有统计学意义（P＜0.05）。 结论 排龈线联合止血剂法和双线排龈法均被证实为较好的排龈 方法，在龈沟止血效果方面，排龈线联合止血剂明显优于双线排龈法。
Abstract:
Objective To evaluate the effect gingival retraction cord combined with hemostatic agent on the definition of subgingival shoulder in cosmetic restoration of anterior teeth, and to provide the reference for the preparation of clinical impression and cast. Methods A total of 188 teeth in 68 patients in the Department of Stomatology,81Hospita of PLA from October 2013 to October 2014 were randomly divided into control group (83) and the test group (105); the control group used double retraction, the test group was treated with gingival retraction cord combined with hemostatic method. After Gingival retraction, impressions were made and superhard gypsum model were finished. The shoulder of the abutment teeth, the hemostatic effects of gingival sulcus, the effect of sulcular opening on the casts were comprehensively observed between the two groups. Results The effects of preparation, impression, casts and restorations between the two kinds of gingival retraction techniques were not significantly different (P>0.05); but significant difference were showed in hemostasis effect (P<0.05). Conclusion The two gingival retraction techniques have been confirmed as a better method, but the gingival retraction cord combined with hemostatic agents has showed significantly better quality in hemostasis effect.
