Abstract:
1. A method for designing a customized tooth movement system for eliciting a selected movement of a patient's tooth, the method comprising: receiving, on a computer, a digital model of the patient's tooth; quantifying, using the computer, a desired force system for eliciting the selected tooth movement when applied to the patient's tooth; selecting, using the computer, a first non-custom attachment configured to engage an orthodontic appliance when worn by a patient, wherein the orthodontic appliance comprises a shell aligner; determining, using the computer, a first force system for application to a tooth having the first non-custom attachment and engaged with an orthodontic appliance; and designing, using the computer, a second custom attachment by modifying a configuration of the first non-custom attachment based on one or more patient-specific characteristics comprising tooth morphology, tooth or tooth surface orientation, or a prescribed tooth movement path, such that a second force system would be applied to a tooth having the second custom attachment and engaged with an orthodontic appliance, the second force system more closely corresponding to the desired force system than the first force system.
