Abstract

Methods, devices, systems, and series of appliances are provided for dental implant positioning. One method for positioning an implant with dental treatment includes determining an implant location based on a virtual model of an optimized dental occlusion, moving one or more teeth using a first number of a series of dental appliances, from a first orientation to a second orientation, the second orientation exposing the implant location, placing an implant at the exposed implant location using a landmark included in at least one of the series of dental appliances, repositioning one or more teeth using a second number of the series of dental appliances, from the second orientation to a successive orientation.

Claims

1. An appliance, comprising:

a plurality of cavities shaped to receive and reposition one or more teeth in a dentition from a first arrangement to a second arrangement different than the first arrangement, the dentition including a vacancy due to one or more misaligned teeth;

an implant-receiving region adjacent to at least one of the plurality of cavities and shaped to be positioned in the vacancy of the dentition, the implant-receiving region configured to cooperate with the plurality of cavities to adjust a shape of the vacancy for accepting a dental implant;

a radiopaque indicator configured to direct placement of the dental implant into the vacancy of the dentition; and

an attachment mechanism to attach the radiopaque indicator to the appliance.

2. The appliance of claim 1, wherein the attachment mechanism comprises one or more of:

a self-adhesive;

a curable adhesive;

a snapping mechanism;

a hook and loop mechanism;

a suction mechanism; and

a clip-on mechanism.

3. The appliance of claim 1, wherein the radiopaque indicator includes a marking device that marks an area of tissue to identify to a clinician a desired position to place the dental implant.

4. The appliance of claim 1, wherein the radiopaque indicator includes a feature to facilitate identifying a tissue area for a clinician to identify a desired position to place the dental implant.

5. The appliance of claim 1, wherein the attachment mechanism is releasable to allow adjustment of the positioning of the radiopaque indicator.

6. The appliance of claim 5, wherein the radiopaque indicator includes a locking mechanism to lock the radiopaque indicator in an adjusted position after adjustment of the positioning in order to verify the adjusted position for placement of the dental implant.

7. The appliance of claim 1, wherein a length dimension of the radiopaque indicator is adjustable.

8. The appliance of claim 7, wherein the radiopaque indicator includes a locking mechanism for locking the length dimension to secure the radiopaque indicator for placement of the dental implant.

9. The appliance of claim 1, wherein at least a portion of the radiopaque indicator is telescopic.

10. The appliance of claim 1, wherein the radiopaque indicator comprises a pointing device, an aperture, or a surgical guide configured to direct placement of the dental implant.

11. The appliance of claim 1, wherein the implant-receiving region comprises an open space adjacent to the at least one of the plurality of cavities.

12. The appliance of claim 1, wherein the implant-receiving region is configured to adjust a position of one or more teeth away from the vacancy.

13. The appliance of claim 1, wherein the implant-receiving region comprises an artificial tooth.

14. The appliance of claim 1, wherein the radiopaque indicator is attached to the implant-receiving region.

15. A method of adjusting a dentition for a dental implant, comprising:

sequentially placing a number of dental appliances to the dentition according to a treatment plan, wherein each of the dental appliances comprises a plurality of cavities shaped to receive and reposition one or more teeth of the dentition from a first configuration to a second configuration different than the first configuration, wherein the dentition includes a vacancy due to one or more misaligned teeth, at least one dental appliance including an implant-receiving region adjacent to at least one of the plurality of cavities and shaped to be positioned in the vacancy of the dentition, the implant-receiving region configured to cooperate with the plurality of cavities to adjust a shape of the vacancy for accepting the dental implant, wherein the at least one dental appliance includes a radiopaque indicator attached to the at least one dental appliance by an attachment mechanism, the radiopaque indicator configured to direct placement of the dental implant into the vacancy of the dentition.

16. The method of claim 15, wherein:

the indicator includes a number of different lines and end points to provide a reference location for the dental implant; and

wherein the method includes placing the dental implant at the reference location via the number of different lines and end points.

17. The method of claim 15, wherein:

the indicator is a pointer configured to provide a directional orientation for the dental implant; and

wherein the method includes placing the dental implant using the directional orientation via the pointer.

18. The method of claim 15, wherein:

the indicator is a U-shape configured to provide a directional orientation for the dental implant; and

wherein the method includes placing the dental implant using the directional orientation via the U-shape.

19. The method of claim 15, wherein the indicator is a circle and reference line configured to provide a reference location for the dental implant.

20. The method of claim 19, wherein the method includes:

marking an area of tissue at the reference location via the circle to identify to a clinician the reference location to place the dental implant; and

placing the dental implant at the reference location.

21. The method of claim 19, wherein the method includes placing the dental implant through the circle at the reference location.

22. The method of claim 19, wherein the method includes placing the dental implant at the reference location using the reference line.

23. A plurality of dental appliances for repositioning one or more teeth of a dentition, the plurality of dental appliances comprising:

at least one dental appliance including;

a plurality of cavities shaped to receive and reposition the one or more teeth in the dentition from a first arrangement to a second arrangement different than the first arrangement, the dentition including a vacancy due to one or more misaligned teeth;

an implant-receiving region adjacent to the at least one of the plurality of cavities and shaped to be positioned in the vacancy of the dentition, the implant-receiving configured to cooperate with the plurality of cavities to adjust a shape of the vacancy for accepting a dental implant;

a radiopaque indicator attached to the implant-receiving region, the radiopaque indicator configured to direct placement of the dental implant into the vacancy of the dentition; and

an attachment mechanism to attach the radiopaque indicator to the at least one dental appliance.

24. The plurality dental appliances of claim 23, wherein:

the radiopaque indicator includes at least one of a rotating joint and pivoting joint; and

wherein the at least one rotating joint and pivoting joint is configured to adjust the radiopaque indicator to a reference location for placement of the dental implant.

25. The plurality dental appliances of claim 23, wherein:

the radiopaque indicator includes at least one of a telescoping and locking telescoping mechanism; and

wherein the at least one of the telescoping and locking telescoping mechanism is configured to adjust the radiopaque indicator to a reference location for placement of the dental implant.

26. The plurality of dental appliances of claim 23, wherein the radiopaque indicator comprises a pointing device, an aperture, or a surgical guide configured to direct placement of the dental implant.

27. The plurality of dental appliances of claim 23, wherein the implant-receiving region comprises an open space adjacent to the at least one of the plurality of cavities.
