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…

Date: September 2015. Source: 8th International Orthodontic Congress 2015, London. Study Aims: To analyse the facial features associated with hypodontia using 3D surface imaging and establish the effect of its severity on facial morphology. Method: A study group of 70 hypodontia patients and a control group of 40 Class I patients were recruited to allow…

Evaluation of Nasal Soft Tissue Changes in a Newborn with Unilateral Cleft Lip and Palate Before and After Nasoalveolar Molding Using a Three-Dimensional System. F Ozturk, E Cakir, SA Ozturk, E Hatunoglu.

Date: September 2015. Source: 8th International Orthodontic Congress 2015, London. Introduction: The pre-surgical nasoalveolar molding (PNAM) treatment protocol for cleft patients has been described by Grayson et al. (1993), Brecht et al. (1995), and Cutting et al. (1998). Pre-surgical nasal molding produces tissue expansion of the columella and nasal lining. The purpose of this case…

Evaluating 3-Dimensional Soft Tissue Changes in Class III Chinese Patients after Orthognathic Surgery. JX Su, M Yow, MT Chew, HC Wong.

Date: September 2015. Source: 8th International Orthodontic Congress 2015, London. Aim: To evaluate facial soft tissue changes in Class III skeletal Chinese patients who have undergone orthognathic surgery. Objective. To determine if there is a correlation between hard and soft tissue movement after orthognathic surgery. Study Design: This is a retrospective study involving 15 Chinese…

Assessment of the effects of different rapid maxillary expansion appliances on facial soft tissues using three-dimensional imaging, S Altındiş, E Toy, FA Başçiftçi.

Date: September 18, 2015. Source: Angle Orthodontist [Epub]. Objective: To determine three-dimensional (3D) effects of three different rapid maxillary expansion (RME) appliances on facial soft tissues. Materials and Methods: Forty-two children (18 boys, 24 girls) who required RME treatment were included in this study. Patients were randomly divided into three equal groups: banded RME, acrylic…

Facial Scanning With a Digital Camera: A Novel Way of Screening for Primary Angle Closure. HKY Choi, W Lin, SC Loon, C Tan, W Wong, J See, Z Gu, CK Kwoh, P Chew.

Date: September 2015 Source: Journal of Glaucoma, Volume 24 – Issue 7 – p 522–526. Purpose: We hypothesize that patients with primary angle closure (PAC) have common significant facial characteristics that set them apart from an age-matched, sex-matched, and race-matched control population. The primary objective of this study was to test whether a 3-dimensional (3D)…
