ENHANCING DENTAL VIDEO TO CT MODEL REGISTRATION AND AUGMENTED REALITY AIDED DENTAL TREATMENT

摘要

Disclosed herein methods and systems for registering intraoral frames of a patient to a dental CT model of the patient, comprising receiving a dental 3D visual model of a patient created based on an intraoral scan of the patient captured after one or more teeth of the patient are marked with intraoral markers located inside the patient's mouth, registering the 3D visual model to a 3D CT model of the patient, receiving intraoral frames captured during a dental treatment to the patient, each frame depicts at least some of the intraoral markers, registering each frame to the 3D visual model based on the intraoral markers, registering each frame to the 3D CT model based on its registration to the 3D visual model registered to the 3D CT model, and creating a plurality of fused frames each merging a respective frame with a corresponding segment of the registered 3D CT model.
