Trueness and Precision of Economical Smartphone-Based Virtual Facebow Records.

ABSTRACT:

Purpose

To investigate the trueness and precision of virtual facebow records using a smartphone as a three-dimensional (3D) face scanner.

Material and methods

Twenty repeated virtual facebow records were performed on two subjects using a smartphone as a 3D face scanner. For each subject, a virtual facebow was attached to his/her maxillary arch, and face scans were performed using a smartphone with a 3D scan application. The subject's maxillary arch intraoral scan was aligned to the face scan by the virtual facebow fork. This procedure was repeated 10 times for each subject. To investigate if the maxillary scan is located at the right position to the face, these virtual facebow records were superimposed to a cone-beam computed tomography (CBCT) head scan from the same subject
