“…The biggest difference between virtual surgery and traditional methods practised on phantom heads is that virtual surgery not only provides a clean and non-polluting training environment, but also allows users to receive realistic force feedback akin to practice on real teeth [1][2][3][4]. Traditional training methods are limited due to a decrease in the availability of extracted teeth for preclinical 1 Dangxiao Wang and Siming Zhao contributed equally to the paper.teaching uses.…”

“…Traditional training methods are limited due to a decrease in the availability of extracted teeth for preclinical 1 Dangxiao Wang and Siming Zhao contributed equally to the paper.teaching uses. Additionally, the dust generated by drilling teeth during the training process may pollute the environment and be harmful to the students [2]. The emergence of haptic-based virtual dental training systems provides an alternative new way for dental drilling training.…”

“…The Simodont Dental Trainer (MOOG Inc. & ACTA (Academic Centre for Dentistry Amsterdam), Netherlands) could simulate dental drilling, the removal of tooth decay, the filling of cavities, crown and bridge preparation as well as mirror reflection [5]. The HapTEL system (The Kings College London & University of Reading, UK) allows users to learn and practice procedures such as dental drilling, caries removal and cavity preparation for tooth restoration [2]. The Forsslund system (Forsslund Systems AB, Sweden) has been designed to provide virtual reality training and practice in dental drilling and wisdom tooth extraction [3].…”

“…The results showed that the skills were transferred successfully, and students and teachers were satisfied with the various aspects of the Simodont. Jonathan et al [2,8] evaluated the hardware and software of the HapTEL impact on teaching and learning, and concluded that the finger rest, dental tools, software, and collocation among hand, eye and tool should be merited high priority. Forsslund et al [9] implemented a subjective evaluation of the Forsslund System to verify design decisions and collect input for modifications of future iterations.…”

Abstract.To evaluate the fidelity of the iDental system and investigate its utility and performance on simulated drilling operations, user studies consisting of objective and subjective evaluations were performed. A voxel-based drilling simulation sub-system in the iDental system was employed for evaluation. Twenty participants were enrolled to take part in the experiments and were divided into two groups: novice and resident. A combined evaluation method including objective and subjective methods was employed. The objective evaluation included two dental drilling tasks: caries removal operation and pulp chamber opening operation. In the subjective method, participants were required to complete a questionnaire to evaluate the fidelity of the system after the operation task. Based on the structured global assessment scales in the questionnaire, the average subjective evaluation scores of the proposed metrics were greater than 4.5, demonstrating that the system operated above medium fidelity. Dentists expressed great interest and positive attitudes toward the potential of the iDental system. The objective evaluation data including time spent and the volume of removed healthy and carious tissue were obtained. Although no significant differences could be found between the two groups, the volume of removed caries and the depth of pulp chamber insertion manifested small standard deviations. Evaluation results illustrated that dentists were willing to use the virtual reality training system. Several future research topics were identified, including increasing the task difficulty, improving the system fidelity and introducing appropriate finger rest points.

“…1,2 These discussions are particularly timely as they come at a point when virtual reality simulators (often relying on 3D stereo-projected images to create 'realistic' dental environments) are becoming increasingly popular in the education of tomorrow's dentists. [3][4][5] Such devices have raised questions about whether stereoprojected images are a necessary feature of simulators. [6][7][8] This relates to the larger issue of whether an ability to perceive the information that arises specifically from a binocular view should be a prerequisite for surgical training.…”

Objectives Administering anesthesia to the inferior alveolar nerve is 1 of the most stressful processes in dental training. Most studies using virtual reality (VR) for dental training have used non‐immersive technologies. The purpose of this work is to assess the impact of immersive technologies on skills training. Methods On May 2019, an experimental study was conducted with 163 clinical dental students, divided into 4 groups across 2 phases (preceptorship and training) with haptic feedback either On or Off. The participants trained on the inferior alveolar dental anesthesia procedure in a haptic VR simulator. Their technical skills were evaluated in terms of needle insertion features which were computed from a haptic device providing kinematic data. Also, the participants reported their subjective experience with syringe handling and simulator sickness. A machine learning method was implemented to automatically evaluate the needle insertion point performance of the student. Results Groups receiving immersive preceptorship and/or immersive training showed more accuracy and confidence in administering the anesthesia. Participants perceived a high sense of realism with the haptic feedback when handling the syringe. The machine learning method was validated, with an accuracy of 84%, as a good classifier to assess a student's needle insertion point performance. Conclusions The immersive VR simulator allows the practice of the inferior alveolar nerve block under near real conditions and with immediate feedback to the dental student with respect to the needle insertion point. This machine learning based automatic evaluation provides a method to improve technical skills, contributing to dental training.
