摘要/Abstract

摘要： 目的: 评价三维数字化微笑设计（three-dimensional digital smile design,3D-DSD）联合双定位冠延长导板在前牙美学修复中的临床效果。方法: 选择需行上前牙美学牙冠延长术和全冠修复的患者20例,随机分为实验组和对照组,每组10例。实验组进行3D-DSD,3D打印双定位冠延长导板,指导美学牙冠延长术,术后3个月进行全冠修复。对照组采用传统美学牙冠延长术和全冠修复。术前、术后3个月、术后6个月进行粉白美学指数（pink esthetic score/white esthetic score,PES/WES）评估,术后6个月、7个月采用视觉模拟评分法（visual analogue scales,VAS）进行2次患者满意度评价,对2次VAS结果进行可重复性评价,并对术后6个月PES/WES评分和整体满意度进行相关性分析。采用SPSS 23.0软件包对数据进行统计学分析。结果: 2组患者术后3个月、术后6个月PES/WES评分均高于术前（P<0.05）。组间比较结果显示,术后3个月PES、术后6个月PES和WES,实验组显著高于对照组（P<0.05）。满意度调查结果显示,2次VAS结果的组内相关系数为0.956（P<0.05）;实验组牙冠长宽比例、微笑曲线、个性特征、患者参与度和整体满意度均优于对照组（P<0.05）。术后6个月PES和WES评分与整体满意度均呈正相关（r_S1=0.905,P<0.001;r_S2=0.460,P=0.041）。结论: 3D数字化微笑设计联合双定位冠延长导板指导前牙美学牙冠延长术和修复治疗,可提高治疗后粉白美学效果及患者满意度。

Abstract: PURPOSE: To evaluate the clinical effect of three-dimensional digital smile design (3D-DSD) combined with double positioning crown extension guide in aesthetic restoration of anterior teeth. METHODS: Twenty patients who needed aesthetic crown lengthening and full crown restoration of upper anterior teeth were selected and randomly divided into the experimental group and control group, with 10 cases in each group. The experimental group carried out 3D-DSD, after confirming the plan, 3D printed double positioning crown extension guides were used to guide aesthetic crown lengthening, and full crown was completed 3 months after operation. The control group used traditional aesthetic crown lengthening and full crown restoration. PES/WES evaluation was performed before operation, three months and six months after operation. Visual analogue scales(VAS) were used to evaluate patient satisfaction 6 and 7 months after surgery, and the repeatability evaluation of VAS was conducted. The correlation between PES/WES score and overall satisfaction was analyzed 6 months after operation. SPSS 23.0 software package was used for statistical analysis. RESULTS: The PES/WES scores of the two groups of patients at 3 months and 6 months after operation were higher than those before operation(P<0.05). The two groups showed that the scores of the experimental group were significantly higher than those of the control group for PES 3 months after operation, PES and WES 6 months after operation(P<0.05).Satisfaction survey results showed that the intra-group correlation coefficient of the two VAS results was 0.956(P<0.05),and crown length-to-width ratio, smile curve, personality characteristics, patient participation and overall satisfaction in the experimental group were better than those of the control group(P<0.05).The results of Speraman correlation analysis showed that PES and WES scores at 6 months after operation were positively correlated with overall satisfaction (r_s1=0.905, P<0.001; r_s2=0.460, P=0.041). CONCLUSIONS: 3D digital smile design combined with double positioning crown extension guide guides the anterior aesthetic crown lengthening and restoration treatment, which can improve the effect of pink and white aesthetics after treatment and patient satisfaction.
