摘要

目的研究数字扫描结合逆向工程技术在全冠牙预备演示中的效果:将 31 名学生随机分为两组。对照组学生使用眼动测量法进行传统演示。实验组的学生通过使用带有三维测量数据的数字化口内扫描进行改进示范。两组学生都获得了两颗树脂牙,在头模牙科模拟器上进行全冠牙预备。按照中华口腔医学会团体标准对演示前后的牙齿预备情况进行评分,总分为 100 分。对两组牙面和收敛角的相关评分进行协方差分析比较:对两组准备好的两颗牙齿(11 号牙和 16 号牙)进行的分析表明,对照组和实验组的平均得分差异有统计学意义(11 号牙,P = 0.0039)(16 号牙,P = 0.0120)。0205)和近端面(P = 0.0023)在对照组和实验组之间存在统计学差异;颊舌面收敛角相关评分在对照组和实验组之间存在统计学差异(P = 0.0265):数字化方法能有效提高牙体预备的质量,对于操作难度较大的后牙具有教学优势。

Investigation on the Effectiveness of Digital Scanning Combined with Reverse Engineering Technology in Demonstrating Full-Crown Tooth Preparation.

Purpose: To investigate the effect of digital scanning combined with reverse engineering technology in the demonstration of full-crown tooth preparation.

Materials and methods: A total of 31 students were randomly divided into two groups. The students in the control group conducted traditional demonstration using eye-measurement methods. The students in the experimental group carried out improved demonstration using digital intraoral scans with 3D-measurement data. The students in both groups were provided with two resin teeth to conduct full-crown tooth preparation on head model dental simulators. The teeth prepared before and after demonstration were scored according to Chinese Stomatological Association Group Standards with a total score of 100 points. Analysis of covariance (ANCOVA) was performed to comparatively analyze the scores related to the tooth surfaces and the convergence angle between the two groups.

Results: Analysis of two prepared teeth (a maxillary right central incisor and first molar) in two groups showed that there was a statistically significant difference in the mean score between the control group and experimental group (central incisor, P = .0039; first molar, P = .0120). The demonstration of the first molar showed that there were statistically significant differences in the scores related to the buccolingual surface (P = .0205) and proximal surface (P = .0023) between the control group and experimental group. There was a statistically significant difference in the score related to the convergence angle of the buccolingual surface between the control group and experimental group (P = .0265).

Conclusions: The digital method can effectively improve the quality of tooth preparations and has a pedagogic advantage for posterior teeth, which present greater operational challenges.
