Method to visualize and manufacture aligner by modifying tooth position

A non-transitory computing device readable medium storing instructions executable by a processor to cause a computing device to perform a method, the method comprising:

• determining a target position for at least one tooth of a patient’s teeth as part of an orthodontic treatment plan;
• accessing a database comprising overcorrection data, wherein the overcorrection data comprises discrepancies between force systems applied during an orthodontic treatment and actual teeth positions achieved as a result of the orthodontic treatment;
• determining an overcorrection position for the at least one tooth, wherein the overcorrection position is determined based at least in part on the overcorrection data, and wherein the overcorrection position is determined to facilitate movement of the at least one tooth towards the target position;
• determining a geometry of a dental appliance, wherein the geometry comprises a plurality tooth of receiving cavities, and wherein the geometry is determined to urge the at least one tooth towards the overcorrection position;
• and
• generating instructions for fabrication of the dental appliance in accordance with the determined geometry.
