The point-based surface registration method involves the manual selection process of paired matching points on the data of\ncomputed tomography and optical scan. The purpose of this study was to investigate the impact of selection error and\ndistribution of fiducial points on the accuracy of image matching between 3-dimensional (3D) images in dental planning\nsoftware programs. Computed tomography and optical scan images of a partial edentulous dental arch were obtained. Image\nregistration of the optical scan image to computed tomography was performed using the point-based surface registration\nmethod in planning software programs under different conditions of 3 fiducial points: point selection error (0, 1, or 2 mm),\npoint distribution.............................
