3-Dimensional Facial Simulation in Orthognathic Surgery: Is It Accurate? SA Schendel, R Jacobson, S Khalessi.

Date: Aug 2013. Source: Journal of Oral and Maxillofacial Surgery, 71(8):1406-14. Purpose: The purpose of this study was to measure the accuracy of 3D computer simulation of soft tissue changes after orthognathic surgery. Materials and Methods: Consecutive patients who underwent orthognathic surgery were studied by photogrammetric facial scanning and cone-beam computed tomography before and after…

Cardiff Scientists and 3dMD Enter a New Dimension in 3D/4D Facial Imaging.

Anaheim, California (23-July-13): A team of Cardiff University clinicians and computer scientists can, for the first time, carry out facial movement research and transform the way patients needing facial surgery are assessed and monitored thanks to a new state-of-the-art 3D surface motion imaging system from 3dMD (3dMD exhibiting at #SIGGRAPH2013 Booth 226). Working alongside the…

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…

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…

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…

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…

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…

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…
