Extraoral facial scanning using a mobile phone has emerged as a viable, cost-effective option for certain applications not requiring high precision, such as patient education and 3-dimensional (3D) digital smile design. This technological development is particularly promising for general practitioners (GPs) who may not be able to invest in expensive,complex digital impressioning devices. This article describes and illustrates a relatively simple and accessible workflow that avails digital 3D facial scanning benefits to GPs.

Department of Orthodontics, Sivas Cumhuriyet University Faculty of Dentistry, Sivas, Turkey. Electronic address:
Introduction: This study aimed to evaluate maxillary dental midline shifts and mandibular asymmetries created in different amounts and directions on photographs taken from 7 different angles by different groups and to determine acceptable esthetic limits.
Methods: Photographs of a female model in a social smile position were taken from 7 different angles (0° [frontal], 15°, 30°, and 45° on the right and left sides) and digitally modified for maxillary dental and mandibular midline deviations at specified degrees using Adobe Photoshop. To enable participants to evaluate the photographs sequentially, the photographs were transformed into videos using Adobe Premiere Pro software.

The desire for an attractive smile is a major reason people seek orthodontic and other forms of cosmetic dental treatment. An understanding of the features of a smile is important for dental diagnosis and treatment planning. The common methods of smile analysis rely on the visual analysis of smile aesthetics using posed photographs, and videos and gathering information about smiles through patient questionnaires and diaries.
