Augmented Kinematic Feedback from Haptic Virtual Reality for Dental Skill Acquisition

Abstract

We have developed a haptic virtual reality system for dental skill training. In this study we examined several kinds of kinematic information about the movement provided by the system supplement knowledge of results (KR) in dental skill acquisition. The kinematic variables examined involved force utilization (F) and mirror view (M). This created three experimental conditions that received augmented kinematic feedback (F, M, FM) and one control condition that did not (KR-only). Thirty-two dental students were randomly assigned to four groups. Their task was to perform access opening on the upper irst molar with the haptic virtual reality system. An acquisition session consisted of two days of ten trials of practice in which augmented kinematic feedback was provided for the appropriate experimental conditions after each trial. One week after, a retention test consisting of two trials without augmented feedback was completed. The results showed that the augmented kinematic feedback groups had larger mean performance scores than the KR-only group in Day 1 of the acquisition and retention sessions (ANOVA, p<0.05). The apparent differences among feedback groups were not signiicant in Day 2 of the acquisition session (ANOVA, p>0.05). The trends in acquisition and retention sessions suggest that the augmented kinematic feedback can enhance the performance earlier in the skill acquisition and retention sessions.

Novel Coronavirus (COVID-19) and Dentistry–A Comprehensive Review of Literature

“…Research has shown that a VR simulation facility alongside an experienced instructor providing real-time feedback is the most productive method of teaching in a simulation environment. It improves students' hand-eye coordination, fine motor skills and reflection skills and becomes especially effective in the very early stages of skill acquisition leading to a conservative preparation approach and better skill retention [84][85][86]. Thus, it can be proposed that VR simulation technology is a useful supplementary tool to conventional dental training approaches, and its effective and safe use possibly with some modifications to allow distance learning can be considered during COVID-19 pandemic.…”

Feedback and motor skill acquisition using a haptic dental simulator

“…Additionally, learners with low visual‐spatial ability seem to benefit more from simulation training than conventional training . The role of feedback in dental pre‐clinical training has also been investigated in conventional , computer‐assisted and VR environments . In conventional pre‐clinical operative training (phantom head simulators), the effect of providing continuous concurrent feedback from an instructor has been found to result in significant performance improvements relative to presentation of terminal KR feedback alone .…”

Virtual Reality as a novel educational tool in pre‐clinical paediatric dentistry training: Students’ perceptions

“…The most distinguishing feature of haptic simulators (Simodont ® ) is the science of creating a sense of real touch in a virtual environment to allow the user to realistically 'feel' what they are working on. 9 It was introduced by Moog (Nieuw-Vennep, the Netherlands) and named as Simodont ® Dental Trainer (Figure 1). The device teaches the user to drill in a representative and virtual manner.…”
