Outline of Final Research Achievements |
We examined precision of the orthgnathic surgery simulation using the X-rays CT which we take before and after surgery. The three-dimensional cephalometric analysis and surgery simulation were carried out in SimPlantO & O. We conducted the method to trasfer a Maxilla position at simulation to real surgery by a method to reproduce the distance of the X,Y,Z direction during an operation using an exclusive jig. It was carried out by the ICP method in SimPlantO & O, and the superimposition of both output it in STL file. Using spGauge, we conducted alining it and precision inspection by the best fit method. The surgery precision by the fundamental law was clinically uneventful precision at mean error 0.03mm to 0.43mm.
