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…
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 Aim: To evaluate the possible soft tissue changes after the debonding of orthodontic fixed attachments using the 3dMDface System (3dMD, Atlanta). Method: Three dimensional images of 20 subjects were taken in natural head position before and after the debonding procedure with the 3dMD system.…
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…
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…

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…
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…
Date: August 2015. Source: Angle Orthod. [Epub ahead of print] Objective: To assess the range of social smile reproducibility using 3-D stereophotogrammetry and reverse engineering technology. Materials and Methods: Social smile images of white adolescents (N=15, mean age = 15.4 ±1.5 years; range = 14-17 years) were obtained using 3dMDflex (3dMD, Atlanta, Ga). Each participant was asked…
Date: July 2015. Source: Health Monitoring and Personalized Feedback using Multimedia Data. Springer. Abstract: Craniofacial researchers have used anthropometric measurements taken directly on the human face for research and medical practice for decades. With the advancements in 3D imaging technologies, computational methods have been developed for the diagnoses of craniofacial syndromes and the analysis of…
Date: July 2015 Source: Medicine Science | International Medical Journal. Abstract: The facial morphologies of identical twins were compared using the 3dMD three-dimensional (3D) photogrammetry system. 3D images of the faces of 27-year-old identical twins were acquired and then superimposed. The differences were shown in a color histogram generated using 3dMD Vultus software. The faces…
