Figure 9. The angulation errors between the cylinders 1 and 3 in degrees for the three intra-oral scanners.

Figure 9

The angulation errors were small and ranged from −0,1447° (CEREC) to 1,0456° (CEREC). The iTero showed the smallest mean angulation error. The Lava COS showed the smallest variations. The Lava COS showed only positive errors, while the iTero showed only negative errors. Only the Lava COS showed consistent positive errors in all cases, this could be regarded as an offset which may be compensated.
