This invention concerns a set of three-dimensional markers that should be included in the scanning protocol. These markers together with the scanned information of the dental arches allow the transposition of the terminal hinge axis (for axiography) and the determination of the individual values of the condylar guidance angle and Bennett angle (for virtual articulators) to the virtual articulator. This invention involves a marker () which has three elements: upper element (), intermediate element () and lower element (). These components fit together forming a single piece (), or the elements () () () respectively, in case of edentulous patients that does not allow the attachment, it should be used the spacer (); and markers () (), which are exclusives for individual values determination. 1. Set of three-dimensional markers characterized by:{'b': 1', '10', '14', '11', '14, 'a) upper element () that has a projection () in the upper front area. This projection has two slots () on lateral inner sides. It develops into a depression (), which also presents two slots () on the lateral inner side;'}{'b': 2', '3', '6', '7, 'b) intermediate element () and lower element (), each one having two lateral projections () () on the upper front area;'}{'b': 2', '1', '8', '9', '1', '2', '3', '6', '7, 'c) both intermediate element () and upper element (), have two lateral slots ()() on the upper rear area. This slots allow elements ()()() to set by sliding and fitting projections ()();'}{'b': 5', '12', '14', '13, 'd) marker () has a two-part symmetrical geometry, each one formed by a projection () with two slots () on lateral inner area. This slots also develop into a depression and a second projection () which also has two slots on lateral inner area; or'}{'b': 16', '25', '24', '24', '16', '16', '27, 'e) spacer () shows the groove () at the bottom and has three top grooves () These grooves () have a lower dimension on the outside of spacer () in comparison with the one shown on the ...
