摘要/Abstract

摘要： 目的: 评价3D打印双定位冠延长导板联合3D打印临时冠对前牙红色美学修复的临床效果。方法: 将20例（70颗前牙）需行前牙美学修复的患者随机分为 3D打印组（9例,共 36颗前牙）和传统修复组（11例,共34颗前牙）。3D打印组行数字化设计,3D打印制作双定位冠延长导板,指导冠延长手术,术后佩戴3D打印的临时冠;传统组行诊断蜡型设计,传统压膜制作冠延长导板,冠延长术后制作3D打印临时冠。在佩戴临时冠后1、3、6个月,从牙龈乳头指数（PIS）、红色美学指数（PES）、白色美学指数（WES）及患者满意度等方面评价临床修复效果。采用SPSS 28.0软件包对数据进行统计学分析。结果: 3D打印组6个月时的PIS评分显著优于传统修复组（P<0.05）,3D打印组1、3、6个月时的PES评分显著高于传统修复组（P<0.05）,3D打印组1个月和6个月时的WES评分显著高于传统修复组（P<0.05）。3D打印组患者的总满意度评分高于传统修复组。结论: 应用数字化设计3D打印方法制作的双定位冠延长导板和临时冠,指导前牙美学冠延长术和修复治疗,可以提高美学修复效果,使患者有更佳的美学修复体验。

Abstract: PURPOSE: To evaluate the clinical effect of 3D printing double positioning crown extension guide combined with 3D printing temporary crown in red aesthetic restoration of anterior teeth. METHODS: Twenty patients (70 teeth in total) who needed aesthetic restoration were randomly divided into 3D printing group (9 cases, 36 teeth) and traditional restoration group (11 cases, 34 teeth). The 3D printing team performed digital design, 3D printing double positioning crown lengthening guide to help crown lengthening operation, and 3D printed temporary crown was used after operation. The traditional group underwent diagnostic wax design, traditional film compression to make crown extension guide, 3D printed temporary crown after crown extension, and scored at 1 month, 3 months and 6 months after wearing the temporary crown. The clinical effect was evaluated from papilla index score(PIS), pink esthetic score(PES), white esthetic score(WES) and patient satisfaction. SPSS 28.0 software package was used for statistical analysis of the data. RESULTS: The PIS score of the 3D printing group at 6 months was significantly better than that of the traditional restoration group(P<0.05). The PES scores of 3D printing group at 1, 3 and 6 months were significantly higher than those of traditional restoration group(P<0.05). WES scores at 1 month and 6 months in the 3D printing group were significantly higher than those in the traditional restoration group(P<0.05). The overall satisfaction score of patients in the 3D printing group was higher than that in the traditional restoration group. CONCLUSIONS: The application of digital design, 3D printing double positioning crown extension guide and temporary crown to guide aesthetic crown lengthening and restoration of anterior teeth can improve the effect of aesthetic restoration and make patients have better aesthetic restoration experience.
