Abstract

Methods for accommodating dental implants in treatment planning. Methods may include generating a treatment plan to treat a dentition using a series of dental appliances, where a position of a digital implant in a digital dental model is identified. At least one dental appliance of the series of dental appliances may be created, where the at least one dental appliance may be shaped to implement at least one stage of the treatment plan and include an offset portion that is shaped to provide a space between the offset portion and an actual implant to avoid impingement of the at least one dental appliance on the actual implant and allows for osseointegration of the actual implant.

First claim

What is claimed is:

1. A method comprising:
scanning a dentition and surrounding soft tissue and bone structure;
creating a digital dental model based on the scan; and
generating a treatment plan to treat the dentition using a series of dental appliances,
wherein generating the treatment plan comprises:
identifying a position for a digital implant in the digital dental model, wherein the position corresponds to a desired position for an actual implant in the bone structure; and
providing instructions to place the digital implant at the position of the digital dental model; and

creating at least one dental appliance of the series of dental appliances, the at least one dental appliance shaped to implement at least one stage of the treatment plan, the at least one dental appliance including an offset portion that is shaped to provide a space between the offset portion and the actual implant to avoid impingement of the at least one dental appliance on the actual implant and allows for osseointegration of the actual implant.

2. The method of claim 1 , wherein scanning the dentition comprises taking a computerized tomography (CT) scan of the dentition.

3. The method of claim 1 , wherein scanning the dentition comprises using x-rays of the dentition.

4. The method of claim 1 , wherein identifying the position for the digital implant in the digital dental model comprises optimizing a dental occlusion of the dentition during one or more stages of the treatment plan.

5. The method of claim 4 , wherein optimizing the dental occlusion comprises arranging a bite relationship between lower and upper jaws of the digital dental model such that resulting forces on the actual implant are favorable for long-term success of the actual implant.

6. The method of claim 1 , wherein identifying the position for the digital implant in the digital dental model comprises avoiding one or more of nerves, blood vessels and adjacent tooth roots.

7. The method of claim 1 , wherein identifying the position for the digital implant in the digital dental model comprises considering aesthetic results.

8. The method of claim 1 , further comprising generating output for forming the series of dental appliances according to the treatment plan.

9. The method of claim 1 , wherein the series of dental appliances is shaped to apply forces to provide a vacancy for the actual implant between adjacent teeth of the dentition.

10. The method of claim 1 , further comprising forming a virtual indicator in the digital dental model that indicates the position for the digital implant in the digital dental model and for the actual implant in the dentition.

11. The method of claim 10 , wherein the virtual indicator includes an abutment feature.

12. The method of claim 1 , further comprising forming a tooth-like object in the digital dental model at the position for the digital implant.

13. A method comprising:
creating a digital dental model based on a scan of a patient's dentition including teeth, surrounding soft tissue and bone structures;
generating a treatment plan to move the teeth of the patient's dentition through a series of tooth arrangements using a series of dental appliances, wherein generating the treatment plan comprises:
identifying a position for a digital implant in the digital dental model, wherein the position corresponds to a desired position for an actual implant in the bone structure; and
modifying a position of one or more teeth of the digital dental model as part of the treatment plan to provide a vacancy at the position of the patient's dentition for the digital implant; and

creating a dental appliance of the series of dental appliances, the dental appliance shaped to implement a corresponding stage of the treatment plan, the dental appliance including an offset portion that is shaped to provide a space between the offset portion and the actual implant to avoid impingement of the dental appliance on the actual implant and allows for osseointegration of the actual implant.

14. The method of claim 13 , wherein the scan of the patient's dentition comprises a computerized tomography (CT) scan of the patient's dentition.

15. The method of claim 13 , wherein the scan of the patient's dentition comprises an x-ray scan of the patient's dentition.

16. The method of claim 13 , wherein identifying the position for the digital implant in the digital dental model comprises optimizing a dental occlusion of the patient's dentition during one or more stages of the treatment plan.

17. The method of claim 13 , wherein identifying the position for the digital implant in the digital dental model comprises avoiding one or more of nerves, blood vessels and adjacent tooth roots.

18. The method of claim 13 , wherein modifying the position of the one or more teeth comprises widening a space between adjacent teeth.

19. A method comprising:
creating a digital dental model from a scan of a patient's dentition including teeth, surrounding soft tissue, and bone structures; and
generating a treatment plan to treat the patient's dentition using a series of dental appliances, wherein generating the treatment plan comprises:
identifying a position for a digital implant in the digital dental model, wherein the position corresponds to a desired position for an actual implant in the bone structure; and

creating a dental appliance of the series of dental appliances, the dental appliance shaped to implement a corresponding stage of the treatment plan, the dental appliance including an offset portion that is shaped to provide a space between the offset portion and the actual implant to avoid impingement of the dental appliance on the actual implant and allows for osseointegration of the actual implant.

20. The method of claim 19 , wherein generating the treatment plan comprises modifying a position of one or more teeth of the digital dental model as part of the treatment plan to provide a vacancy at the position of the patient's dentition for the digital implant.
