TOOTH MODELING SYSTEM

摘要

Systems and methods are disclosed for treating teeth to correct for malocclusions. This may be accomplished by applying a series of labels to a digital dental model and applying a rolling ball process to identify tooth boundaries separating one tooth from a neighboring tooth and to also determine the crown/gum margin. The user may further assign regions to the dental model to indicate hard regions and soft regions. With the dental model labeled and defined, the user may then generate a treatment plan for moving the labeled and defined tooth or teeth relative to one another to correct for any malocclusions. Upon approval of the treatment plan, a series of 3D printed dental appliances or aligners to be worn in series by the patient may be fabricated to ultimately move the tooth or teeth to a desired position.

主权项

1. A method for planning a treatment for correcting malocclusions, comprising:
receiving a scanned dental model of a subject's dentition; applying a label to one or more teeth within the dental model; simulating a rolling ball process along an exterior of the one or more teeth and gums within the dental model; determining a boundary between each of the one or more teeth and gums based on a path or trajectory of the rolling ball process; assigning a hard or soft region to each of the one or more teeth and gums within the dental model; moving a position of the one or more teeth within the dental model to correct for malocclusions in developing a treatment plan; and fabricating one or more aligners to move the one or more teeth according to the treatment plan.
