Method for selecting implant components
View Patent ↗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.
1. 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.
2. The method of claim 1 , wherein determining properties determines the properties of the bone present in the anatomical area.
3. The method of claim 1 , wherein determining properties determines a magnitude of bone density of the anatomical area.
4. The method of claim 1 , wherein selecting the implant selects a 3D CAD model of the implant from a CAD library and adds the implant to the 3D CAD model.
5. The method of claim 1 , wherein confirming is based upon optimizing initial implant stability while utilizing the necessary transient [a] torque to seat the implant in the bone.
6. The method of claim 1 , wherein confirming is based upon verifying that a maximum stress level is not surpassed in the bone surrounding the implant.
7. A method of optimizing 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 osteotomy variable to be optimized by a FEA simulation;
performing a real-time FEA simulation of placing the implant in the desired location within the 3D CAD model to optimize the assigned osteotomy 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
optimizing the osteotomy for the anatomical area based upon results from performing the FEA simulation and the necessary transient torque.
8. The method of claim 7 , wherein determining properties determines the properties of the bone present in the anatomical area.
9. The method of claim 7 , wherein determining properties determines a magnitude of bone density of the anatomical area.
10. The method of claim 7 , wherein optimizing the osteotomy includes determining at least one osteotomy dimension from the FEA simulation.
11. The method of claim 7 , wherein the osteotomy variable includes at least one of length, diameter, or tap type.
12. The method of claim 7 , wherein the anatomical area is a patient's mouth and the implant is a dental implant.
