Abstract
Disclosed is a method for determining the geometrical relationship between a patient's dental structure and a reference feature on the head of the patient, the method including obtaining a first digital representation of a facebow including a fiducial marker, an adjustable pin member attached to the facebow and an attachment section of the facebow for placing the facebow in relation to the reference feature, the attachment section having a geometrical relationship with the fiducial marker; obtaining a second digital representation comprising a part of the patient's dental structure, a part of the pin member, and part of the facebow including the fiducial marker; obtaining information about the placement of the attachment section relative to the reference feature; and determining the geometrical relationship between the patient's dental structure and the reference feature based on the first and second digital representations and the placement of the attachment section.
