Augmented reality: a new perspective in dental education

INTRODUCTION The Microsoft HoloLens is a mixed reality device with the capability to provide a real-time 3D platform using multiple sensors and holographic processing to display information, and even to simulate a virtual world. With rapidly evolving technology and virtual learning on the increase, the HoloLens can be used as a vital tool for education and surgical planning. The aim of this pilot study was to ascertain its benefit in dental education and in the surgical planning of complex oral surgery procedures. METHODS A cohort of postgraduate dentists working at the Eastman Dental Hospital in London were shown two holographic videos. Participation was voluntary and an email invitation was sent to all non-consultant grade dental staff across multiple dental specialties. The cases demonstrated were a mandibular third molar in close association with the inferior alveolar nerve and an impacted tooth. Each video had a narration and explanation by a consultant oral surgeon. After having watched the videos, participants were asked to rate seven statements using a Likert scale. RESULTS Eighty-two per cent of participants reported improved comprehension of orientating anatomical structures. All participants (100%) noted improved confidence in surgical planning. Ninety-four per cent believed that the technology was an invaluable surgical tool in postgraduate training. CONCLUSIONS Augmented reality has the potential to change the face of surgery in the 21 st century. This technology can be used to improve surgical training, especially in an environment where hands-on training is limited and virtual learning is promoted.
