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…

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…

Date: November 2012 Source: Angle Orthodontist; 82(6): pp 985-92. Abstract: Objective: To determine the linear, volumetric, and cross-sectional area measurements in a large sample of subjects seeking treatment in a university clinic of orthodontics. Materials and Methods: Cone-beam computed tomography (CBCT) scans from 387 patients were analyzed retrospectively. All scans were loaded into the 3dMDvultus…

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…

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…
