目的

探寻改良E字法口内扫描在口腔正畸数字化印模制作中的应用。

方法

选取2022年3月——2024年3月南京大学医学院附属口腔医院采用数字化印模技术进行口腔正畸的患者120例，根据随机数表法分为试验组（扫描方式为改良E字法口内扫描）和对照组（扫描方式为分段法），各60例。比较两组扫描时间、扫描舒适度、正畸效果及满意度。

结果

试验组扫描时间显著短于对照组，扫描舒适度评分显著高于对照组，差异有统计学意义（P<0.05）。试验组总有效率高于对照组，差异有统计学意义（P<0.05）。试验组满意度高于对照组，差异有统计学意义（P<0.05）。

结论

改良E字法口内扫描能显著扫描效率、患者舒适度、正畸效果、满意度，改善口腔健康问题对生活质量影响，具有积极的临床应用价值。

Objective

To explore the application of improved E-word intraoral scanning in the production of orthodontic digital impression.

Methods

A total of 120 patients who underwent orthodontic treatment with digital impression technology in Nanjing Stomatological Hospital, Medical School of Nanjing University from March 2022 to March 2024 were selected. According to the random number table method, they were divided into the experimental group (the scanning method was modified E-word intraoral scanning) and the control group (the scanning method was segmented method), with 60 cases in each group. The scanning time, scanning comfort, orthodontic effect and satisfaction were compared between the two groups.

Results

The scanning time of the experimental group was significantly shorter than that of the control group, and the comfort score was significantly higher than that of the control group, with statistically significant differences (P<0.05). The total effective rate of the experimental group was higher than that of the control group, with a statistically significant difference (P<0.05). The satisfaction rate of the experimental group was higher than that of the control group, with a statistically significant difference (P<0.05).

Conclusion

The modified E-word intraoral scanning can significantly improve the scanning efficiency, patient comfort, orthodontic effect, satisfaction, and improve the impact of oral health problems on the quality of life.
