Abstract

Introduction

Nowadays, the training of implant placement has shifted from once entirely instructor–student teaching to the increasing use of computer-assisted simulation. Based on computerized virtual planning, dynamic navigation has been used for implant placement with higher accuracy than the traditional freehand protocol. However, whether dynamic navigation benefits to the training of dental students in implant placement remains controversial. This study aimed to compare the surgical performance of dental students in implant placement using computer-assisted dynamic navigation and freehand approaches.

Materials and Methods

A total of 20 dental students (6 males, 14 females, age: 25.6 ± 0.5 years) were enrolled in this study. With the traditional freehand approach (training 1) as the control protocol, computer-assisted dynamic navigation (training 2) was used in the training of dental students in implant placement. For each training, both the operating time (OT) of students and placement accuracy represented by the linear (at the implant platform, D_pl, and apex, D_ap) and angular (D_an) deviations between the virtually planned and placed implants were recorded. Statistical comparisons were made between the two training protocols as well as male and female surgeons.

Results

OT₂ was around twice of OT₁ (p < .0001), whereas D_an1 was almost three times of D_an2 (p < .0001). D_ap1 and D_pl1 were significantly higher than D_ap2 (p = .014) and D_pl2 (p = .033) respectively. Besides, male students showed statistically higher D_pl1 (p = .033) and D_an1 (p = .002) than females. No significant difference was found between male and female students in OT₁, OT₂, D_pl2, D_ap1, D_ap2 and D_an2.

Conclusions

Within the limitations of this study, the use of computer-assisted dynamic navigation in the preclinical training could improve the surgical performance of the dental students in implant placement. The combination of dynamic navigation with the traditional preclinical surgical training may benefit to dental students and could be applied in dental education.

牙科学生使用计算机辅助动态导航和徒手入路的手术表现。

引言：如今，植入物植入的培训已经从曾经的完全由讲师授课转变为越来越多地使用计算机辅助模拟。基于计算机虚拟规划，动态导航已被用于植入物的放置，其精度高于传统的徒手协议。然而，动态导航是否有利于牙科学生的种植体植入培训仍然存在争议。本研究旨在比较牙科学生在使用计算机辅助动态导航和徒手方法进行种植体植入时的手术表现。材料和方法：共20名牙科学生（6名男性，14名女性，年龄：25.6岁） ± 0.5 年）被纳入本研究。以传统的徒手方法（训练1）为控制协议，将计算机辅助动态导航（训练2）用于牙科学生的种植体植入训练。对于每次训练，记录学生的操作时间（OT）和由实际计划和放置的植入物之间的线性（在植入物平台Dpl和顶点Dap）和角度（Dan）偏差表示的放置精度。对两种培训方案以及男性和女性外科医生进行了统计比较。结果：OT2约为OT1的两倍（p an1几乎是Dan2的三倍（p ap1和Dpl1显著高于Dap2（p = .014）和Dpl2（p = .033）。此外，男性学生的Dpl1（p = .033）和Dan1（p = .002）比雌性大。男女学生在OT1、OT2、Dpl2、Dap1、Dap2和Dan2方面没有发现显著差异。结论：在本研究的限制范围内，在临床前训练中使用计算机辅助动态导航可以提高牙科学生在种植体植入中的手术表现。将动态导航与传统的临床前外科训练相结合，可能有利于牙科学生，并可应用于牙科教育。

期刊介绍： The aim of the European Journal of Dental Education is to publish original topical and review articles of the highest quality in the field of Dental Education. The Journal seeks to disseminate widely the latest information on curriculum development teaching methodologies assessment techniques and quality assurance in the fields of dental undergraduate and postgraduate education and dental auxiliary personnel training. The scope includes the dental educational aspects of the basic medical sciences the behavioural sciences the interface with medical education information technology and distance learning and educational audit. Papers embodying the results of high-quality educational research of relevance to dentistry are particularly encouraged as are evidence-based reports of novel and established educational programmes and their outcomes.
