6. The method of claim 1 , wherein the treatment plan has a plurality of dental appliances and wherein the appliances include an aligner and an attachment.
7. The method of claim 1 , wherein determining the desired force parameters include data from at least one of: a patient's mouth, typodont data, and scanned dental appliance data.
8. The method of claim 1 , wherein the dental appliance material properties and characteristics include thickness of the dental appliance, dimples in the dental appliance, reinforcement structures, and strength of material used to construct the dental appliance.
9. A system for virtually identifying force placed on teeth, comprising:
a processor;
memory having instructions executable by the processor to:
receive initial orthodontic data (IOD) of teeth of a patient;
identify a virtual target dental model of the teeth based on the IOD representing a treatment plan;
identify one or more virtually created dental appliances utilized in the treatment plan;
compute one or more desired force parameters of a dental appliance to achieve a particular position of a particular segment of the treatment plan; and
estimate forces generated by the virtually created dental appliance as applied to one or more teeth and verify that the virtually created dental appliance is applying a desired force parameter to the one or more teeth based on a comparison of the desired force parameters and the estimated forces.
10. The system of claim 9 , wherein the desired force parameters and estimated actual forces present include at least one of a relative magnitude of point contact force of the dental appliance, an amount of stress on the dental appliance, and individual contacts of the dental appliance.
11. The system of claim 10 , wherein the relative magnitude of point contact force is displayed on a user interface as force and torque vector arrows showing a direction and magnitude.
12. The system of claim 10 , wherein the amount of stress on the dental appliance is displayed on a user interface as a light number of dots to a heavier number of dots scale.
13. The system of claims 10 , wherein the individual contacts of the dental appliance are displayed as arrows.
14. The system of claim 9 , wherein the estimated forces present on the virtually created dental appliance are displayed on a user interface.
15. The system of claim 9 , wherein the system includes a library of data including at least one of: tooth shapes, appliance shapes, appliance characteristics, mounting material characteristics, tooth structures, and mouth structures.
16. A non-transitory computing device memory having executable instructions that can be executed by a processor to cause a computing device to perform a method of virtually identifying force placed on a tooth, comprising:
