Detailed Description
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.

Outcome Measures
Primary Outcome Measures
- the accuracy of different virtual articulator mounting procedures [immediately]
the virtual articulator mounting by using JMA is considered as the the gold standard, which can calculate the hinge axis of the temporomandibular joint, compare the hinge axis of the temporomandibular joint of different virtual articulator mounting procedures.
