SYSTEMS AND METHODS FOR GUIDING DENTAL TREATMENT UTILIZING MIXED REALITY

Dental treatment can be provided by a system that overlays a treatment template on a patient's arch in mixed reality, enabling a practitioner to view a schematic of the dental treatment while administering the treatment itself. The system employs a physical guide which includes stabilizing pieces to hold the guide steady with respect to the area of the arch where treatment is being administered. When the physical guide is scanned, a virtual guide is produced, in relation to which the treatment template can be defined. When the physical guide is installed on the patient, the virtual guide is aligned with the physical guide, thus aligning the template with the physical arch. With the physical guide firmly in place, the guides provide abundant feature points for reliable alignment which can be maintained even while practitioners and patient's readjust their positioning throughout a treatment, or in situations where the oral anatomy may not be visible to a mixed reality device.
