The purpose of the present study was to evaluate the accuracy of various virtual articulator mounting procedures. For this purpose, 7 kinds of virtual mounting procedures were investigated:(1) indirect virtual mounting in MS VA by using an average facebow; (2) virtual mounting in MS VA by using average values; (3) virtual mounting in MS VA by using professional facial scanner; (4) virtual mounting in MS VA by using smartphone facial scanner; (5) virtual mounting in MS VA by using CBCT located in Bergstrom's point; (6) virtual mounting in MS VA by using CBCT located in the medial poles of the condyles; (7) virtual mounting in CA VA by using JMA，as the group to compare with the other mounting procedures. The null hypothesis is that no difference would be found in the static measurements taken virtually when comparing these 7 procedures for virtual mounting.
the aim of this study was to evaluate the accuracy of the various virtual articulator mounting procedures.
