Validation of a new three-dimensional imaging system using comparative craniofacial anthropometry.

Background: The aim of this study is to validate a new three-dimensional craniofacial stereophotogrammetry imaging system (3dMDface) through comparison with manual facial surface anthropometry. The null hypothesis was that there is no difference between craniofacial measurements using anthropometry vs. the 3dMDface system.

Submental-Cervical Angle: Perceived Attractiveness and Threshold Values of Desire for Surgery.

Aim: The submental-cervical angle may alter as a result of mandibular orthognathic surgery and/or the ageing process and is therefore an important facial aesthetic parameter for comparative diagnosis and treatment planning. The purpose of this study was to undertake a quantitative evaluation of the influence of the submental-cervical angle on perceived attractiveness and threshold values of desire for surgery.

Study Design: The submental-cervical angle of an idealized profile silhouette image was altered incrementally between 90° and 130°.

Relationship between maxillary central incisor proportions and facial proportions.

Statement Of Problem: No universally accepted parameter exists for selecting maxillary central incisors (MCIs) relative to facial proportions.

Purpose: The purpose of this prospective clinical study was to determine the relationship between MCIs and facial height and width in adults, intersex differences, and measurement differences between right and left MCI.

Material And Methods: A prospective study was undertaken of 149 dental students (F:76; M:73) aged between 18 and 30 years.

Assessing the influence of mandibular prominence on perceived attractiveness in the orthognathic patient, clinician, and layperson.

The purpose of this investigation was to undertake an objective and quantitative evaluation of how mandibular prominence influences perceived attractiveness. The mandibular prominence of an idealized profile image was altered in 2 mm increments from -16 to 12 mm, in order to represent retrusion and protrusion of the mandible, respectively. These images were rated on a 7-point Likert scale by a preselected group of pre-treatment orthognathic patients, clinicians, and laypeople.
