Date: July/August 2018. Source: American Journal of Human Biology, Volume 30, Issue 4. Objective: We compared digital 3D stereophotogrammetry to more traditional measurement methods (direct anthropometry and 2D scanning) to capture digit lengths and ratios. Methods: The length of the second and fourth digits was measured by each method and the second‐to‐fourth ratio was calculated.…
Date: July 2018. Source: Cornell University Library – arXiv.org, Computer Science, Computer Vision. Abstract: Objects that undergo non-rigid deformation are common in the real world. A typical and challenging example is the human faces. While various techniques have been developed for deformable shape registration and classification, benchmarks with detailed labels and landmarks suitable for evaluating…
Date: July 2018. Source: Journal of Oral and Maxillofacial Surgery, Volume 76, Issue 7, pp 1563.e1-1563.e18. Objective: Orthognathic surgery with simultaneous condylectomy under digital guidance has been proved to be a feasible method to treat hemimandibular hyperplasia (HH). The objective of this study was to evaluate the effects and precision of correction of HH by…
Date: June 2018. Source: Clinical Oral Investigations. Objective: To assess the influence of involuntary facial expressions on 3D facial stereophotogrammetry reproducibility in children with and without unilateral cleft lip, alveolus and palate (UCLP) aged 3–18 months. Methods: Three to eight 3D facial images per time point were acquired within 10 min of 31 children with…
Date: June 2018 Source: Respirology, Volume 23, Issue 6, pp 560-561. Abstract: Craniofacial structure is an important anatomical determinant of obstructive sleep apnoea (OSA). While obesity is the major attributing risk factor for OSA, it is well established that a restricted craniofacial bony skeleton also contributes to a more collapsible upper airway, which is a…
Date: June 2018. Source: Journal of Cranio-Maxillofacial Surgery, Volume 46, Issue 6, pp 974-978. Abstract: This study was carried out on 26 unilateral cleft lip and palate (UCLP) cases with mean age 3.6 ± 0.7 months. 3D facial images were captured for each infant 2–3 days before the repair of cleft lip and at 4…
Date: June 2018. Source: Journal of Cranio-Maxillofacial Surgery, Volume 46, Issue 6, pp 987-993. Objective: In the first months of life, any deviation from a physiological growth pattern can cause skull deformity. As there has not been any longitudinal three-dimensional (3D) study investigating the physiological growth of the infant skull, the aim of the present…
Date: June 2018. Source: Digital Technologies in Craniomaxillofacial Surgery, pp 55-65. Abstract: Current treatment planning and reconstruction of craniofacial trauma has been advanced greatly due to the increase in the use of software to convert medical image files in the form of Digital Imaging and Communications in Medicine (DICOM) to 3D reconstructions and ultimately files…
Date: June 2018. Source: Journal of Turkish Orthodontics; 31: 32-6. Objective: : The aim of this study was to use three-dimensional images to determine the presence of upper lip asymmetry at rest and during smiling in a group of individuals with no history of orthodontics or facial cosmetic surgery. Methods: Standardized three-dimensional frontal resting and smiling…
Date: May 2018. Source: Dentistry Journal, Volume 6, Issue 2, 16. Background: Three-dimensional (3D) images could provide more accurate evaluation for facial attractiveness than two-dimensional (2D) images. The 3D facial image could be simplified into gray scale 3D contour lines. Whether female facial attractiveness could be perceived in these simplified 3D facial contour lines should…
