Augmented reality guidance for dental procedures
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.
1. 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 Panorex x-ray image data of at least one anatomic structure of the mandible, at least one anatomic structure of the 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 Panorex x-ray image data,
wherein the at least one processor is configured to register the Panorex 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 Panorex x-ray image data, and
wherein the at least one processor is configured to generate a display of the Panorex 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 Panorex 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.
2. The system of claim 1 , wherein the display of the Panorex 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.
3. The system of claim 1 , wherein the at least one processor is configured to perform a magnification correction of the Panorex x-ray image data.
4. The system of claim 1 , wherein the at least one processor is configured to track the at least one marker in a coordinate system during movement.
5. The system of claim 1 , wherein the dental procedure comprises a root canal procedure or a dental implant procedure.
6. The system of claim 1 , wherein the at least one physical anatomic structure of the mandible or the at least one physical anatomic structure of the maxilla comprises an area between two teeth, an area of a missing tooth, an area of an extracted tooth, a portion of a gum, a gingival tissue, an alveolar bone or a combination thereof.
7. The system of claim 1 , wherein the at least one physical anatomic structure of the tooth comprises the entire tooth, a portion of the tooth, an enamel, a dentin, a pulp, a cementum, a cementoenamel junction, a periodontal ligament, a root, a root canal or a combination thereof.
8. The system of claim 1 , wherein the at least one see through optical head mounted display is registered in a coordinate system.
9. The system of claim 1 , wherein the display of the Panorex x-ray image data by the at least one see through optical head mounted display comprises a virtual axis.
10. The system of claim 9 , wherein the virtual axis is a digital representation indicating a predetermined position, predetermined orientation, or combination thereof 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 a combination thereof for at least one physical dental tool, or wherein the virtual axis is a digital representation indicating a predetermined position, predetermined orientation, or combination thereof in relationship to the at least one anatomic structure of the mandible, the at least one anatomic structure of the maxilla, the at least one anatomic structure of the tooth or a combination thereof in the Panorex x-ray image data for at least one physical dental tool.
11. The system of claim 10 , wherein the at least one physical dental tool comprises a probe or a drill.
12. The system of claim 10 , wherein the at least one physical dental tool is registered in a coordinate system.
13. The system of claim 10 , wherein the at least one physical dental tool is tracked.
14. The system of claim 1 , wherein the marker comprises an active marker, a passive marker, an infrared marker, a radiofrequency marker, a retroreflective marker, an LED, or a combination thereof.
15. The system of claim 1 , wherein the system comprises a surgical navigation system, a camera, an image capture system, a 3D scanner or a combination thereof.
16. The system of claim 1 , wherein the system comprises a user interface.
17. The system of claim 16 , wherein the at least one user interface comprises a graphical user interface, a voice recognition, a gesture recognition, a virtual interface displayed by the at least one see through optical head mounted display, a virtual keyboard displayed by the at least one see through optical head mounted display, a physical keyboard, a physical computer mouse, a physical track pad, or combinations thereof.
18. The system of claim 15 , wherein the camera is head mounted with the stereoscopic optical see-through head mounted display.
19. The system of claim 15 , wherein the at least one camera is separate from the stereoscopic optical see-through head mounted display.
20. The system of claim 1 , wherein the at least one marker comprises a geometric pattern.
