Date: April 2016 Source: Biology of Sex Differences. Background: Although craniofacial sex differences have been extensively studied in humans, relatively little is known about when various dimorphic features manifest during postnatal life. Using cross-sectional data derived from the 3D Facial Norms data repository, we tested for sexual dimorphism of craniofacial soft-tissue morphology at different ages.…

Date: March 2016 (Online ahead of print) Source: The Cleft Palate-Craniofacial Journal. Objective: Quantitative measures of facial form to evaluate treatment outcomes for cleft lip (CL) are currently limited. Computer-based analysis of three-dimensional (3D) images provides an opportunity for efficient and objective analysis. The purpose of this study was to define a computer-based standard of…

Date: February 2016. Source: PLOS | One. Objective: 1) To determine the accuracy and reliability of an automated anthropometric measurement software for the oropharyngeal airway and 2) To compare the anthropometric dimensions of the oropharyngeal airway in skeletal class II and III deformity patients. Methods: Cone-beam CT (CBCT) scans of 62 patients with skeletal class…

Facial soft-tissue changes after rapid maxillary expansion analyzed with 3-dimensional stereophotogrammetry: A randomized, controlled clinical trial. A Baysal, MA Ozturk, AO Sahan, T Uysal.

Date: February 2016 (ONLINE AHEAD OF PRINT). Source: Angle Orthodontist Objective: To evaluate three-dimensional (3D) soft tissue facial changes following rapid maxillary expansion (RME) and to compare these changes with an untreated control group. Materials and Methods: Patients who need RME as a part of their orthodontic treatment were randomly divided into two groups of…

Date: February 2016 (ONLINE AHEAD OF PRINT). Source: Angle Orthodontist Objective: To evaluate the intraexaminer repeatability and interexaminer reproducibility of soft tissue landmarks on three-dimensional (3D) stereophogrammetric images. Materials and Methods: Thirty-four stereophotogrammetric images were taken and 19 soft tissue points were identified. The images were obtained using the 3dMDface (3dMD, Atlanta, USA) system. Two…

Date: January 2016 (Online) Source: The European Journal of Orthodontics. Objective: The shiny vestibular surfaces of teeth make it difficult to match digital dental casts to 3D stereophotogrammetric images of patient teeth. This study tested whether reducing this shininess by coating the teeth with titanium-oxide powder might improve the accuracy of the matching procedure. Methods:…
