Facial soft-tissue changes after rapid maxillary expansion analyzed with 3-dimensional stereophotogrammetry: A randomized, controlled clinical trial. A Baysal, MA Ozturk, AO Sahan, T Uysal.

Date: February 2016 (ONLINE AHEAD OF PRINT). Source: Angle Orthodontist Objective: To evaluate three-dimensional (3D) soft tissue facial changes following rapid maxillary expansion (RME) and to compare these changes with an untreated control group. Materials and Methods: Patients who need RME as a part of their orthodontic treatment were randomly divided into two groups of…

Reproducibility and reliability of three-dimensional soft tissue landmark identification using three-dimensional stereophotogrammetry. A Baysal, AO Sahan, MA Ozturk, T Uysal.

Date: February 2016 (ONLINE AHEAD OF PRINT). Source: Angle Orthodontist Objective: To evaluate the intraexaminer repeatability and interexaminer reproducibility of soft tissue landmarks on three-dimensional (3D) stereophogrammetric images. Materials and Methods: Thirty-four stereophotogrammetric images were taken and 19 soft tissue points were identified. The images were obtained using the 3dMDface (3dMD, Atlanta, USA) system. Two…

Facial morphology in children and adolescents with juvenile idiopathic arthritis and moderate to severe temporomandibular joint involvement. YJ Hsieh, TA Darvann, NV Hermann, P Larsen, YF Liao, J Bjoern-Joergensen, S Kreiborg.

Date: February 2016 Source: American Journal of Orthodontics & Dentofacial Orthopedics. Volume 149, Issue 2, Pages 182–191. Highlights: • We evaluated lateral facial morphology of juvenile idiopathic arthritis patients with moderate and severe TMJ involvement. • Differences in their lateral facial morphologies between unilateral and bilateral TMJ involvement were also assessed. Introduction: The aims of…

Does powdering of the dentition increase the accuracy of fusing 3D stereophotographs and digital dental casts. FA Rangel, YT Chiu, TJJ Maal, EM Bronkhorst, SJ Bergé, AM Kuijpers-Jagtman.

Date: January 2016 (Online) Source: The European Journal of Orthodontics. Objective: The shiny vestibular surfaces of teeth make it difficult to match digital dental casts to 3D stereophotogrammetric images of patient teeth. This study tested whether reducing this shininess by coating the teeth with titanium-oxide powder might improve the accuracy of the matching procedure. Methods:…

A Pilot Study on the Influence of Facial Expression on Measurements in Three-Dimensional Digital Surfaces of the Face in Infants With Cleft Lip and Palate. NV Hermann, TA Darvann, P Larsen, P Lindholm, M Andersen, S Kreiborg.

Date: January 2016. Source: The Cleft Palate-Craniofacial Journal. OBJECTIVE: Three-dimensional surface imaging is an increasingly popular modality for face measurements in infants with cleft lip and palate. Infants are noncompliant toward producing specific facial expressions, and selecting the appropriate moment of acquisition is challenging. The objective was to estimate amount and spatial distribution of deformation…

Regional facial asymmetries and attractiveness of the face. AE Kaipainen, KR Sieber, RM Nada, TJ Maal, C Katsaros, PS Fudalej.

Date: December 2015 Source: The European Journal of Orthodontics. Objective: Facial attractiveness is an important factor in our social interactions. It is still not entirely clear which factors influence the attractiveness of a face and facial asymmetry appears to play a certain role. The aim of the present study was to assess the association between…

Facial asymmetry assessment in adults using three-dimensional surface imaging. Patel et al. 2015.

Date: October 2015. Source: Progress in Orthodontics 201516:36. Background: The use of three-dimensional (3D) surface imaging is becoming more popular and accepted in the fields of Medicine and Dentistry. The present study aims to develop a technique to automatically localise and quantify soft-tissue asymmetry in adults using 3D facial scans. This may be applied as…
