The use of mixed reality in dentistry.

Augmented reality (AR) was first described in the literature in the 1990s. It has been shown as a futuristic concept in television, film and media, and now in the twenty-first century has become a reality. AR is defined as an interactive experience of a real-world environment where the object that resides in the real world is enhanced by computer-generated perceptual information.Microsoft HoloLens is a mixed reality device which has the capability to provide a real-time, three-dimensional platform using multiple sensors and holographic processing to display information and even simulate a virtual world. With rapidly evolving technology and virtual learning on the increase, the HoloLens technology can be used as a vital tool for dental education and surgical planning. However, within dentistry at present, there is limited research regarding its benefits and potential.The authors would like to demonstrate the use of HoloLens in three common oral surgery procedures and how it can be used to distinguish anatomy and benefit surgical planning, aid in patient communication and play a role in dental education.
