A Novel Technique to Align the Intraoral Scans to the Virtual Articulator
Now online in the Journal of Prosthodontics, a report of a digital technique to align intraoral scans to a virtual articulator by using a facial scanner to locate the patient's cutaneous landmarks of the arbitrary hinge axis and the reference plane, and to customize the sagittal condylar inclination of the virtual articulator through a digital protrusive interocclusal record and a dental CAD software program.
Recently, some digital facebow transfer techniques have been proposed to mount intraoral scans on a virtual articulator, however, none of them have introduced the acquisition of patient-specific SCI, which is a crucial setting of the virtual articulator.
The authors describe a technique that can be easily integrated with most virtual articulator systems on the market to allow clinicians and technicians to work in a complete digital workflow and facilitate customized treatment planning and dental prosthesis fabrication.
A 3D facial scanner is required for this workflow, in addition to several software programs and devices which require some additional cost, chairside time, and software operating knowledge.
Future studies are recommended to evaluate methods for measuring the lateral condylar inclination as well as to compare this technique with conventional methods to evaluate its precision and efficiency.
