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.

A method of selecting an implant to be used in an anatomical area of a patient including a bone, the method comprising:
- performing a CT scan of the anatomical area;
- creating a 3D CAD model of the anatomical area utilizing data generated by the CT scan;
- determining properties of the anatomical area based upon data generated by the CT scan;
- assigning the determined properties of the anatomical area to the 3D CAD model;
- selecting a desired location for the implant;
- selecting the implant to be placed into the anatomical area;
- performing a real-time FEA simulation of placing the selected implant in the anatomical area with the 3D CAD model;
- determining a necessary transient torque to seat the selected implant into the anatomical area based on the determined properties of the anatomical area, the selected implant and the desired location via the real-time FEA simulation;
- and
- confirming the selected implant is clinically appropriate based upon the results of the FEA simulation of the 3D CAD model and the necessary transient torque.
A method of creating a protocol for placing an implant in a patient comprising:
- performing a CT scan of an anatomical area of a patient;
- creating a 3D CAD model of the anatomical area utilizing data generated by the CT scan;
- determining properties of the anatomical area based upon data generated by the CT scan;
- assigning the determined properties of the anatomical area to the 3D CAD model;
- selecting a desired location for the implant;
- assigning at least one variable to be optimized by a FEA simulation;
- performing an FEA simulation in real-time of placing the implant into the anatomical area on the 3D CAD model to optimize the assigned variable;
- determining a necessary transient torque to seat the selected implant into the anatomical area based on the determined properties of the anatomical area, the selected implant and the desired location via the real-time FEA simulation;
- and
- choosing a protocol to seat the selected implant based upon results from performing the FEA simulation and the necessary transient torque.
A method of designing an osteotomy to be used in a patient comprising:
- performing a CT scan of an anatomical area of the patient;
- creating a 3D CAD model of the anatomical area utilizing data generated by the CT scan;
- determining properties of the anatomical area based upon data generated by the CT scan;
- assigning the determined properties of the anatomical area to the 3D CAD model;
- selecting a desired location for the implant in the anatomical area;
- assigning at least one variable to be optimized by a FEA simulation;
- performing a real-time FEA simulation of placing the implant in the desired location on the 3D CAD model to optimize the assigned variable;
- determining a necessary transient torque to seat the selected implant into the patient based on the determined properties of the anatomical area, the selected implant and the desired location via the real-time FEA simulation;
- and
- designing the osteotomy for the anatomical area based upon results from performing the FEA simulation and the necessary transient torque.
