Soft-Tissue Volumetric Changes Following Monobloc Distraction Procedure: Analysis Using Digital Three-Dimensional Photogrammetry System (3dMD). FC Chan, HK Kawamoto, C Federico, JP Bradley.

Date: March 2013. Source: Journal of Craniofacial Surgery, Volume 24, Issue 2, pp 416-420. Abstract: We have previously reported that monobloc advancement by distraction osteogenesis resulted in decreased morbidity and greater advancement with less relapse compared with acute monobloc advancement with bone grafting. In this study, we examine the three-dimensional (3D) volumetric soft-tissue changes in…

Multimodal registration of three-dimensional maxillodental cone beam CT and photogrammetry data over time. N Bolandzadeh, W Bischof, C Flores-Mir, P Boulanger.

Date: February 2013. Source: Dentomaxillofacial Radiology, Volume 42, Issue 2. Objectives: In recent years, one of the foci of orthodontics has been on systems for the evaluation of treatment results and the tracking of tissue variations over time. This can be accomplished through analysing three-dimensional (3D) orthodontic images obtained before and after the treatments. Since…

Trisomy 21 and Facial Developmental Instability. JM Starbuck, TM Cole III, RH Reeves, and JT Richtsmeier.

Date: February 2013. Source: American Journal of Physical Anthropology, Volume 151, Issue 1, pp 49-57. Abstract: The most common live-born human aneuploidy is trisomy 21, which causes Down syndrome (DS). Dosage imbalance of genes on chromosome 21 (Hsa21) affects complex gene-regulatory interactions and alters development to produce a wide range of phenotypes, including characteristic facial dysmorphology. Little is known about how…

The facial evolution: looking backward and moving forward. G Baynam, M Walters, P Claes, S Kung, P LeSouef, H Dawkins, D Gillett, J Goldblatt.

Date: January 2013. Source: Human Mutation; 34(1): pp 14-22. Abstract: Three-dimensional (3D) facial analysis is ideal for high-resolution, nonionizing, noninvasive objective, high-throughput phenotypic, and phenomic studies. It is a natural complement to (epi)genetic technologies to facilitate advances in the understanding of rare and common diseases. The face is uniquely reflective of the primordial tissues, and…

Three-Dimensional Assessment of Facial Development in Children With Unilateral Cleft Lip With and Without Alveolar Cleft. M Krimmel, S Kluba, M Breidt, M Bacher, S Müller-Hagedorn, K Dietz, H Bülthoff, S Reinert.

Date: January 2013. Source: Journal of Craniofacial Surgery, Volume 24, Issue 1, pp313-316. Abstract: Children with cleft lip or cleft lip and alveolus represent a minor group in the cleft population. The aim of this study was to analyze the faces of these children. In a prospective, cross-sectional study, 344 healthy children and 30 children…

Development and reproducibility of a 3D stereophotogrammetric reference frame for facial soft tissue growth of babies and young children with and without orofacial clefts. S Brons, ME van Beusichem, TJJ Maal, JM Plooij, EM Bronkhorst, SJ Bergé, AM Kuijpers-Jagtman.

Date: January 2013 Source: International Journal of Oral and Maxillofacial Surgery; 42(1):2-8. Abstract: The aim of this study was to develop a reference frame for three dimensional (3D) facial soft tissue growth analysis in children and to determine its reproducibility. Two observers twice placed the reference frame on 39 3D-stereophotogrammetry facial images of children with…

3D comparison of average faces in subjects with oral clefts. I Bugaighis, B Tiddeman, CR Mattick and R Hobson

Date: November 2012 Source: European Journal of Orthodontics Abstract: This prospective cross-sectional, case-controlled morphometric study assessed three dimensional (3D) facial morphological differences between average faces of 103 children aged 8-12 years; 40 with unilateral cleft lip and palate (UCLP), 23 with unilateral cleft lip and alveolus (UCLA), 19 with bilateral cleft lip and palate (BCLP),…

Application of 3dMD Photogrammetric System for Classification of Hemifacial Microsomia: a Pilot Study. SY SHEN, PF XIN, JW DAI XD WANG, GF SHEN.

Date: November 2012. Source: Journal of Oral and Maxillofacial Surgery; 22(4): pp 261-264. Objective: To introduce a new type of measurement and diagnosis system for classification and treatment planning for hemifacial microsomias. Methods: 14 hemifacial microsomia patients were recruited in this study. Their measurement of volume captured and calculated by 3dMD photogrammetric system were evaluated.…
