Three-dimensional reproducibility of natural head position. DW Weber, DW Fallis, MD Packerc.

Date: May 2013 Source: American Journal of Orthodontics and Dentofacial Orthopedics, Volume 143, Issue 5, pp 738-744. Introduction: Although natural head position has proven to be reliable in the sagittal plane, with an increasing interest in 3-dimensional craniofacial analysis, a determination of its reproducibility in the coronal and axial planes is essential. This study was…

Three-dimensional evaluation of unilateral cleft rhinoplasty results. TK Dixon, BP Caughlin, N Munaretto, DM Toriumi.

Date: April 2013 Source: Facial Plastic Surgery.; 29(2): 106-15. doi: 10.1055/s-0033-1341588. Abstract: Three-dimensional (3D) imaging is a relatively new method of objectively evaluating surgical results, allowing the surgeon to accurately measure postsurgical changes with little inconvenience to the patient. Its accuracy and reliability has been consistently demonstrated in the literature. This article describes updated methods…

3D Facial Morphometry in Children with Oral Clefts. I Bugaighis, CR Mattick, B Tiddeman, R Hobson.

Date: April 2013 Source: The Cleft Palate-Craniofacial Journal Purpose: The aim of this study was to characterize three-dimensional (3D) facial morphological variation of children with cleft lip and palate compared to an age- and sex-matched control group. Materials and Methods: Subjects were 103 children aged 8 to 12 years old with cleft lip and palate—40…

3D Imaging and Informatics Approaches to Diagnose Genetic Conditions. C Deutsch.

Date: April 2013. Source: 2013 Bio-IT World Conference & Expo; Boston, USA. Abstract: With the support of NIH, we have developed the first quantitative normative database to diagnose craniofacial abnormalities. This new informatics resource, combined with novel methods in 3D surface imaging and 3D morphometry, provides the means of defining features of medical genetic conditions.…

Unilateral Condylar Hyperplasia: A 3-Dimensional Quantification of Asymmetry. TJ Verhoeven, JW Nolte, TJJ Maal, SJ Bergé, AG Becking.

Date: March 2013. Source: PLoS ONE.org. Purpose: Objective quantifications of facial asymmetry in patients with Unilateral Condylar Hyperplasia (UCH) have not yet been described in literature. The aim of this study was to objectively quantify soft-tissue asymmetry in patients with UCH and to compare the findings with a control group using a new method. Material…

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…

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…
