The Facial Profiling of Malocclusions: The Promise of Emerging 3-Dimensional Technologies. C Wholley and M Walters

Date: 10-14 February 2012. Source: Australian Society of Orthodontists’ 23rd Congress 2012, Perth, Australia. Abstract: The assessment of facial profile, bite and underlying dental-skeletal discrepancies are critical in the diagnosis and treatment planning of malocclusions. In addition to the clinical evaluation, other records such as facial photography, dental impressions and cephalometry are routinely taken to…

Relation Over Time Between Facial Measurements and Cognitive Outcomes in Fetal Alcohol-Exposed Children. T Foroud, L Wetherill, S Vinci-Booher, ES Moore, RE Ward, HE Hoyme, LK Robinson, J Rogers, EM Meintjes, CD Molteno, JL Jacobson, SW Jacobson.

Date: September 2012. Source: Alcoholism: Clinical and Experimental Research, Volume 36, Issue 9, pages 1634–1646, September 2012. Background: The identification of individuals exposed prenatally to alcohol can be challenging, with only those having the characteristic pattern of facial features, central nervous system abnormality, and growth retardation receiving a clinical diagnosis of fetal alcohol syndrome (FAS).…

Airway Growth and Development: A Computerized 3-Dimensional Analysis. SA Schendel, R Jacobson, S Khalessi.

Date: September 2012. Source: Journal of Oral and Maxillofacial Surgery, Volume 70, Issue 9, Pages 2174–2183. Purpose: The present study was undertaken to investigate the changes in the normal upper airway during growth and development using 3-dimensional computer analysis from cone-beam computed tomography (CBCT) data to provide a normative reference. Methods: The airway size and…

Three-dimensional evaluation of changes in lip position from before to after orthodontic appliance removal. L Eidson, LHS Cevidanes, L Koerich de Paula, HG Hershey, G Welch, PE Rossouw.

Date: September 2012. Source: American Journal of Orthodontics & Dentofacial Orthopedics; Volume 142, Issue 3 , pp 410-418. Introduction: Our objectives were to develop a reproducible method of superimposing 3-dimensional images for measuring soft-tissue changes over time and to use this method to document changes in lip position after the removal of orthodontic appliances. Methods:…

Methods of Measuring the Three-Dimensional Face. NM Souccar, CH Kau.

Date: September 2012. Source: Seminars in Orthodontics; Volume 18, Issue 3, pp 187-192. Abstract: Three-dimensional surface imaging is a popular technique among orthodontists and maxillofacial surgeons. It allows the capture of the face in 3 dimensions and the measurement of distances, surfaces, and volumes. Many devices and analyses have been developed to reconstruct and accurately…

Application of Virtual Surgical Planning with Computer Assisted Design and Manufacturing Technology to Cranio-Maxillofacial Surgery. L Zhao, PK Patel, M Cohen.

Date: July 2012. Source: Archives of Plastic Surgery; Volume 40, Issue 3. Abstract: Computer aided design and manufacturing (CAD/CAM) technology today is the standard in manufacturing industry. The application of the CAD/CAM technology, together with the emerging 3D medical images based virtual surgical planning (VSP) technology, to craniomaxillofacial reconstruction has been gaining increasing attention to…

No evidence for sexual dimorphism of facial width-to-height ratio in four large adult samples. CE Lefevrea, GJ Lewisb, TC Batesc, M Dzhelyovaa, V Coetzeed, IJ Dearyc, DI Perretta.

Date: June 2012. Source: Evolution & Human Behavior. Volume 33, Issue 6 , Pages 623-627. Abstract: Sexual dimorphism in physical appearance may be an important cue in both intra- and intersex competition. Recently, the facial width-to-height ratio (fWHR) has been proposed as a novel sexually dimorphic morphologic measure, with men suggested to have a higher…

Computation of an average cranial shape of three to twelve months old infants using 3D stereophotogrammetry. T Maal, L Verhamme, E van Lindert, W Borstlap, S Berge.

Date: June 28, 2012. Source: 26th International Congress of Computer Assisted Radiology 2012 (CARS) in Pisa, Italy. Purpose: The goal of this study was to create an average cranial shape using an automated process for a control population. This model includes the variation of growth and allows for an easy comparison between patient and average…
