(a) The overall surface deviation of three-dimensional models ranged from 2.5 to 3.4 mm. (b) Surface deviation color maps in 3D models showing the smallest deviation (syCBCT 3). (c) Surface deviation color maps in 3D models show the largest deviation (syCBCT 2). CBCT, cone-beam computed tomography; syCBCT, synthetic CBCT.
