Methods and systems for dental procedures
A device including a coded pattern for use in dental procedures is provided. Related methods and systems are also provided.
1. A device for use in dental scanning procedures of a patient, the device comprising:
a bite plate for securing the device in a mouth of a patient during an optical scan of exposed teeth of the patient; and
an outer structure having a coded pattern integrated therein and being coupled to the bite plate at an angle, the coded pattern for aligning scanned 3D model data of the exposed teeth of the patient, the outer structure and the bite plate being arranged in order to capture the coded pattern in the scanned 3D model data of the exposed teeth.
2. The device of claim 1 , wherein the angle between the outer structure and the bite plate is adjustable around an axis formed by the coupling of the outer structure and the bite plate.
3. The device of claim 1 , further comprising a lip displacement attachment configured to move a lip of the patient so as to expose at least some of the patient's teeth and allow scanning of the coded pattern in relation at least some of the patient's teeth.
4. The device of claim 1 , wherein the coded pattern comprises a plurality of bars oriented in the coded pattern at predetermined distances from each other, intersecting at predetermined angles, or both.
5. The device of claim 1 , wherein the coded pattern comprises horizontal bars intersecting vertically oriented bars disposed at different angles with respect to the horizontal bars.
6. The device of claim 1 , wherein the coded pattern comprises bars in a radial pattern, a crosshatch pattern or a honeycomb pattern.
7. The device of claim 1 , wherein the coded pattern comprises at least one portion that comprises a lengthwise portion forming a reference line for aligning images acquired during the scanning procedure.
8. The device of claim 1 , wherein the device further comprises at least one extension portion capable of being aligned with the sagittal plane of the patient, a plane orthogonal to the sagittal plane, or both.
9. The device of claim 8 , wherein the extension portion is fixedly connected to the coded pattern.
10. The device of claim 1 , wherein the outer structure comprises an oval, circle, square, or rectangular shape.
11. The device of claim 1 , wherein the outer structure comprises an open ring structure.
12. The device of claim 1 , wherein the outer structure comprises a closed ring structure.
13. The device of claim 1 , wherein the coded pattern is formed within the outer structure.
14. The device of claim 1 , wherein the outer structure is positioned in front of the exposed teeth when the device is positioned in the mouth of the patient.
15. The device of claim 1 , wherein the coded pattern further comprises an alignment feature configured to facilitate orienting the coded pattern with a reference on the patient.
16. The device of claim 15 , wherein the reference comprises one or more teeth of the patient.
17. A system for digitally aligning a patient's teeth with a reference portion of the patient, the system comprising:
a device comprising a bite plate for securing the device in a mouth of a patient during an optical scan of exposed teeth of the patient and an outer structure having a coded pattern integrated therein and being coupled to the bite plate, the coded pattern for aligning scanned 3D model data of the exposed teeth of the patient, the outer structure and the bite plate being arranged in order to capture the coded pattern in the scanned 3D model data of the exposed teeth, the device further comprising at least one extension portion capable of being aligned with the reference portion;
a scanner for acquiring a first image of at least the portion of the patient's teeth and a second image of the coded pattern and at least the portion of the patient's teeth; and
a computer comprising storage media comprising instructions that, when executed, cause the computer to determine a spatial relationship between at least some of the patient's teeth and the reference portion associated with the patient by calculating a first spatial relationship between the device and at least the portion of the patient's teeth and a second spatial relationship between the device and the reference portion.
18. The system of claim 17 , further comprising a lip displacement attachment configured to move a lip of the patient so as to expose at least some of the patient's teeth and allow scanning of the coded pattern in relation to at least some of the patient's teeth.
19. The system of claim 17 , wherein the coded pattern comprises a plurality of bars oriented in the coded pattern at predetermined distances from each other, intersecting at predetermined angles, or both.
20. The system of claim 17 , wherein the coded pattern comprises at least one portion that comprises a lengthwise portion forming a reference line for aligning images acquired during the scanning procedure.
21. The system of claim 17 , wherein the reference portion comprises the sagittal plane of the patient, a plane orthogonal to the sagittal plane, or both.
22. The system of claim 17 , wherein the scanner is an optical scanner.
23. The system of claim 17 , wherein the optical scanner comprises confocal optics.
24. The device of claim 1 , wherein the angle between the outer structure and the bite plate is substantially orthogonal.
