Abstract

Introduction: In the last few years, a dramatic development of biometrical recognition systems had evolved, due to increased attention to security. Face scanners are widely used in the medical and dental fields, facial recognition, capturing facial emotions, facial cosmetic planning, and surgical reconstruction. Although various face scanners are available, there is no evidence of a suitable face scanner for practical applications.
Aim of the study: To evaluate the reliability of 3D facial models obtained by different numbers of 2D mobile photogrammetry images on being compared to linear facial 2D point measurements, to be used as viable medical records for the face banking concept.
Materials and Methods: One healthy adult female volunteer participant with a normal face form was selected from those admitted to the prosthodontic department. Using mobile photogrammetry, different counts (60,90, and 120) of 2D images were used to build 3D models which were compared with the real linear face 2D measurements for selected interpoint distances.
Results: Deviation of the anthropometric distances was statistical significance was observed between the real face measurements and all the photogrammetry test groups (P-Value
