3种排龈方法对排龈效果影响的对比研究

摘要

270 patients underwent single crown prosthodontics were randomly divided into 3 groups(n =90)and received gingival retraction with single-cord,double-cord and gingival retraction paste respectively.The prosthesis quality of the 3 groups was not statistically significant (P =3.209).The patient satisfaction was more and the gingival retraction time of the paste group was shorter than those of the cord groups(P<0.05).%为对比临床常用3种排龈方法的排龈效果，将270例需预备龈下肩台的单冠修复者随机分成3组（n ＝90），在制取印模前分别进行单线法、双线法及排龈膏法排龈，随后从印模、模型质量，牙龈出血、患者主观感觉及排龈时间方面，综合评价三者的优劣。三者在修复体质量方面无统计学差异（P ＝3．209），在排龈时间及患者满意度方面，排龈膏组优于排龈线组（P ＜0．05）。
