A digital technique to adjust the disc-condyle relationship based on CBCT-MRI fused 3D images

A digital workflow that can adjust the disc-condyle relationship rapidly and precisely is described. Cone beam computed tomography (CBCT), magnetic resonance imaging (MRI), and an intraoral scan at maximal intercuspal position are superimposed depending on the anatomic structure, and the disc-condyle relationship is adjusted on the fused display of the articular disc and condyle in the CBCT-MRI 3-dimensional spatial environment. An occlusal device is then directly designed and fabricated on the achieved maxillomandibular position, and the occlusal device is finely adjusted intraorally to improve function as needed. This technique can also be seamlessly integrated into the virtual environment to allow clinicians and dental laboratory technicians to design prostheses or treatment planning devices in a fully digital workflow.
