1. A method of selecting an implant to be used in a patient comprising:
- performing a CT scan of the patient'"'"'s mouth;
creating a 3D CAD model of the patient'"'"'s mouth utilizing data generated by the CT scan;
determining properties of the patient'"'"'s mouth based upon data generated by the CT scan;
assigning the determined properties of the patient'"'"'s mouth to the 3D CAD model;
selecting a desired location for the implant;
selecting the implant to be placed into the patient;
performing a real-time FEA simulation of placing the selected implant in the patient'"'"'s mouth with the 3D CAD model;
determining a necessary transient torque to seat the selected implant into the patient based on the determined properties of the patient'"'"'s mouth, the selected implant and the desired location via the real-time FEA simulation; and
confirming the implant chosen by the act of selecting is clinically appropriate based upon the results of the FEA simulation of the 3D CAD model and the necessary transient torque.

Abstract
Methods of selecting or designing an implant to be used in a patient are provided. A CT scan of a patient'"'"'s mouth is performed. A 3D CAD model of the patient'"'"'s mouth is created utilizing data generated by the CT scan. Properties of the patient'"'"'s mouth are determined based upon CT scan data and assigned to the 3D CAD model. A desired location for an implant is selected. A FEA simulation is performed on the 3D CAD model to choose an implant or to design an implant that optimizes a selected variable.
