By Dr Yassine Harichane, Canada Imagine the following scenario: your patient arrives, both relaxed and calm, at your practice. Although the patient is visiting the practice for the ﬁrst time, he is familiar with it and knows its interior well. Without fur- ther introduction, the patient takes a seat in the dental chair, and the orthodontic procedure is performed quickly and comfortably with pa- tient compliance. There are no com- plications or tension, and the treat- ment is easily achieved. Imagine such a soothing and comfortable en- vironment in which to treat patients. Now imagine this very same scenar- io through the eyes of the patient. One can see that it could actually be a comfortable experience. This is not some hypothetical futur- istic utopia; this is actually happen- ing now, and the aforementioned points are some of the many beneﬁts of virtual reality (VR). VR is a process that entails immersing the viewer in a 360° environment. By turning his head left, right, up or down, the patient can visualise a real or an ar- tiﬁcial environment. The spectator could be immersed in the Caribbean Sea surrounded by corals or in a Ca- nadian forest (Fig. 1). The operation is simple: the participant wears a light- weight and comfortable headset in which a smartphone is inserted (Fig. 2). Owing to the gyroscopic sen- sors, the smartphone will project a matching image corresponding to the movements. If the patient raises his head, he will see the sky or the ceiling, and if he lowers his head he will see his feet. This technique is made possible by a 360° shot using a dedicated camera (Fig. 3) and sim- ple editing software (Fig. 4). The re- sult is simply astonishing as we ﬁnd ourselves projected into a place that may vary from actual tourist sites to virtual scenarios as in video games. The applications in orthodontics are numerous and at present we are exploiting only a tiny part of its po- tential functions. The possibilities might be endless. Hence, it might become possible for the patient to visit the dental ofﬁce from his home, where he can visualise the front desk, admire the treatment rooms or view the cleanliness of the sterilisation room (Fig. 5). The aim is to offer a vir- tual visit of the practice to allow the patient to choose a quality clinic, as well as familiarise himself with the space before his ﬁrst appointment. Once physically seated in the chair, the patient can wear the VR headset during the treatment and visualise a restful environment of his choosing. From here on, it is solely a matter of preference as the patient might en- joy the beach, a VR video of Honolu- lu, or maybe even climbing a moun- tain. Any VR video is acceptable, as long as it achieves its purpose: calm- ing the patient during a treatment session. Thus, everything becomes less tense, and the patient is relaxed. This might also be convenient for the dentist, as he can then execute whatever treatment is necessary as quickly and efﬁciently as possible. ÿPage E6
