Individualized orthodontic treatment index

A non-transitory computing device readable medium having executable instructions that can be executed by a processor to cause a computing device to perform a method of using an individualized orthodontic treatment index, comprising:

• receiving an initial virtual dental model associated with a first scan of a patient's dentition;
• modifying the initial virtual dental model to create a target virtual dental model according to a limited treatment target goal of a dentition that is not ideal with respect to an ideal dentition defined according to a non-individualized treatment index;
• assigning a number of dental references to the target virtual dental model;
• mapping the number of dental references from the target virtual dental model to the initial virtual dental model;
• receiving a treatment outcome virtual dental model associated with a second scan of the patient's dentition;
• mapping the number of dental references from the target virtual dental model to the treatment outcome virtual dental model;
• and
• calculating an individualized treatment index score for the treatment outcome virtual dental model according to one or more differences between the target virtual dental model and the treatment outcome virtual dental model based on the mapped number of dental references, wherein the individualized treatment index score characterizes the treatment outcome virtual dental model relative to the limited treatment target goal.

A system for using an individualized orthodontic treatment index, comprising:

• a processor;
• and
• a memory storing data including:
• an initial virtual dental model associated with a first scan of a patient's dentition;
• a target virtual dental model having a number of dental references assigned thereto;
• and
• a treatment outcome virtual dental model associated with a second scan of the patient's dentition;
• and
• the memory storing instructions executable by the processor to provide:
• a treatment module configured to create the target virtual dental model by modifying the initial virtual dental model based on a limited treatment target goal of a dentition that is not ideal with respect to an ideal dentition defined according to a non-individualized treatment index;
• a correlation module configured to map the number of dental references from the target virtual dental model to the initial virtual dental model and to the treatment outcome virtual dental model;
• and
• a calculation module configured to calculate an individualized treatment index score for the treatment outcome virtual dental model according to one or more differences between the target virtual dental model and the treatment outcome virtual dental model based on the mapped number of dental references, wherein the individualized treatment index score characterizes the treatment outcome virtual dental model relative to the limited treatment target goal.
