Orthodontic systems and methods including parametric attachments
First Claim
1. A computer-implemented method for designing a customized tooth movement system for eliciting a selected movement of a patient'"'"'s tooth, the method executed by a physical processor of a computer, the method comprising:
- determining, using instructions executed by the physical processor, a targeted force system configured to elicit the selected movement when applied to the patient'"'"'s tooth;
selecting, using instructions executed by the physical processor, a digital model of a generic tooth attachment configured to engage an orthodontic shell appliance;
determining, using instructions executed by the physical processor, a first force system that would be applied to the patient'"'"'s tooth by engagement of the generic tooth attachment with the orthodontic shell appliance; and
modifying, using instructions executed by the physical processor, one or more parameters of the generic tooth attachment to form a custom tooth attachment, wherein the custom tooth attachment is configured to engage the orthodontic shell appliance so as to apply a second force system to the patient'"'"'s tooth, the second force system more closely corresponding to the targeted force system than the first force system.

Abstract
Orthodontic systems and related methods are disclosed for designing and providing improved or more effective tooth moving systems for eliciting a desired tooth movement and/or repositioning teeth into a desired arrangement. Methods and orthodontic systems of the invention include tooth attachments having improved or optimized parameters selected or modified for more optimal and/or effective application of forces for a desired/selected orthodontic movement. Attachments of the present invention can be customized to a particular patient (e.g., patient-customized), a particular movement, and/or a sub-group or sub-set of patients, and configured to engage an orthodontic tooth positioning appliance worn by a patient, where engagement between the attachment and orthodontic appliance results in application of a repositioning force or series/system of forces to the tooth having the attachment and will generally elicit a tooth movement.

10. A system for designing a customized tooth movement system for eliciting a selected movement of a patient'"'"'s tooth, the system comprising:
-
one or more physical processors; and memory comprising instructions that, when executed by the one or more physical processors, cause the system to; determine a targeted force system configured to elicit the selected movement when applied to the patient'"'"'s tooth; select a digital model of a generic tooth attachment configured to engage an orthodontic shell appliance; determine a first force system that would be applied to the patient'"'"'s tooth by engagement of the generic tooth attachment with the orthodontic shell appliance; and modify one or more parameters of the generic tooth attachment to form a custom tooth attachment, wherein the custom tooth attachment is configured to engage the orthodontic shell appliance so as to apply a second force system to the patient'"'"'s tooth, the second force system more closely corresponding to the targeted force system than the first force system. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
