摘要

研究目的本研究旨在比较临床医生对 3D 打印排牙、商业排牙和人类拔牙的切割反应的触觉感知:方法:要求 20 名临床医生对商用类型牙、3D 打印类型牙和人类拔出的牙齿进行 I 级龋齿预备,并通过三轴称重传感器记录受力情况。临床医生的触觉感知也通过一份问卷进行了评估,问卷中对商用类型牙和 3D 打印类型牙进行了比较:研究发现,临床医生在切割 3D 打印的排畸牙齿(1.37 牛顿)和人类拔出的牙齿(1.44 牛顿)时使用的力相似(p = 0.53),但切割商用排畸牙齿(3.71 牛顿)时需要更大的力。调查问卷显示,临床医生对三维打印类型矫正牙齿的评价高于商用牙齿。三维打印的牙本质得到了临床医生的好评,三维打印的牙釉质与商用牙釉质相比得到了更高的评价:研究结果表明,3D打印的类型牙具有与人类拔牙相当的触觉感受,可作为临床前牙科学习的有效工具。此外,该研究还强调了三维打印排牙在触觉感知方面比商用排牙更有优势。

An evaluation by dental clinicians of cutting characteristics and haptic perceptions in 3D-printed typodont teeth: A pilot study.

Objectives: This study aimed to compare the haptic perception of clinicians to the cutting response of 3D-printed typodont teeth and commercial typodont teeth and human extracted teeth.

Methods: Twenty clinicians were asked to perform a Class I cavity preparation on commercial typodont teeth, 3D-printed typodont teeth, and human extracted teeth, while the forces were recorded via a three-axis load cell. The haptic perception of clinicians was also evaluated through a response questionnaire comparing commercial and 3D-printed typodont teeth.

Results: The study found that clinicians used similar forces (p = 0.53) to cut both the 3D-printed typodont teeth (1.37 N) and the human extracted teeth (1.44 N), but more force was needed to cut the commercial typodont teeth (3.71 N). The response questionnaire indicated that clinicians rated the 3D-printed typodont teeth highly compared to the commercial teeth. The 3D-printed dentine received favorable feedback from clinicians, and the 3D-printed enamel was rated higher compared to the commercial equivalents.

Conclusions: The results of the study suggest that 3D-printed typodont teeth offer a comparable haptic perception to human extracted teeth and can be used as an effective tool for preclinical dental learning. Moreover, the study highlights the advantages of 3D-printed typodont teeth over commercial typodont teeth in terms of haptic perception.

期刊介绍: The Journal of Dental Education (JDE) is a peer-reviewed monthly journal that publishes a wide variety of educational and scientific research in dental, allied dental and advanced dental education. Published continuously by the American Dental Education Association since 1936 and internationally recognized as the premier journal for academic dentistry, the JDE publishes articles on such topics as curriculum reform, education research methods, innovative educational and assessment methodologies, faculty development, community-based dental education, student recruitment and admissions, professional and educational ethics, dental education around the world and systematic reviews of educational interest. The JDE is one of the top scholarly journals publishing the most important work in oral health education today; it celebrated its 80th anniversary in 2016.
