The objective of this study was to assess the accuracy of image registration of the optical scan to 3D CBCT reconstructions with different thresholds of grey values of segmentation in partial edentulous jaw conditions. The null hypothesis was that the threshold of the gray value of segmentation in CBCT and the number of residual teeth would not result in a different image registration accuracy between the optical scan and the CBCT 3D reconstruction model. Thus, based on the findings of this study, the proposed null hypothesis, the thresholds of gray value of segmentation in CBCT, and the number of residual teeth would not influence the accuracy of image registration of the optical scan to the CBCT data, was rejected.	./cache/cord-032625-u8qces3r.txt	./txt/cord-032625-u8qces3r.txt
