Assisted Removal of Impacted Supernumerary Teeth Using HoloLens 2 and Mixed Reality.

This technological innovation introduces a mixed reality-based system using HoloLens 2 for surgical removal of impacted supernumerary teeth. The technology superimposes 3-dimensional virtual models reconstructed from cone-beam computed tomography and intraoral scan data onto the actual surgical field, providing real-time visual guidance for precise localization. This innovative approach enables minimally invasive procedures while eliminating the expenses and limitations associated with traditional surgical guides. Although implementation faces challenges, including hardware costs, operational learning curve, and environmental lighting requirements, the method demonstrates significant potential for reducing surgical trauma and improving outcomes. With anticipated advancements in hardware accessibility and protocol standardization, clinical adoption is projected within 12 to 24 months. The technique also shows promising applications in localizing deep-seated tumors and foreign bodies.
