Abstract
Aspects of the present disclosure relate to systems, devices and methods for performing a surgical step or surgical procedure with visual guidance using an optical head mounted display. Aspects of the present disclosure relate to systems, devices and methods for displaying, placing, fitting, sizing, selecting, aligning, moving a virtual implant on a physical anatomic structure of a patient and, optionally, modifying or changing the displaying, placing, fitting, sizing, selecting, aligning, moving, for example based on kinematic information.
Claims20
A system for preparing a patient for a dental procedure, the system comprising:
- at least one processor,
- at least one see-through optical head mounted display, and
- at least one marker,
- wherein the at least one marker comprises a radiopaque portion and is configured to be attached to a mandibular tissue, a maxillary tissue, a dental tissue or combination thereof of the patient,
- wherein the at least one processor is configured to receive X-ray image data of at least one physical anatomic structure of a mandible, at least one physical anatomic structure of a maxilla, at least one anatomic structure of a tooth or a combination thereof,
- wherein the radiopaque portion of the at least one marker is included in the X-ray image data,
- wherein the at least one processor is configured to register the X-ray image data with the at least one physical anatomic structure of the mandible, the at least one physical anatomic structure of the maxilla, the at least one physical anatomic structure of the tooth or a combination thereof using the radiopaque portion of the at least one marker included in the X-ray image data, and
- wherein the at least one processor is configured to generate a display of the X-ray image data by the at least one see-through optical head mounted display, and is configured to superimpose or align the display of the X-ray image data at a predetermined position, orientation or position and orientation with at least a portion of the at least one physical anatomic structure of the mandible, at least a portion of the at least one physical anatomic structure of the maxilla, at least a portion of the at least one physical anatomic structure of the tooth, or a combination thereof,
- wherein the display of the X-ray image data at the predetermined position, orientation or position and orientation is parallel, tangent, or intersecting in relationship to the at least one physical anatomic structure of the mandible, the at least one physical anatomic structure of the maxilla, the at least one physical anatomic structure of the tooth, or the combination thereof.
