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…

Measuring Symmetry in Children With Cleft Lip. Part 2: Quantification of Nasolabial Symmetry Before and After Cleft Lip Repair. J Wu, S Liang, L Shapiro, R Tse.

Date: December 2015. Source: The Cleft Palate-Craniofacial Journal. Objective: The first part of this study validated an automated computer-based method of identifying the three-dimensional midfacial plane in children with unrepaired cleft lip. The purpose of this second part is to develop computer-based methods to quantify symmetry and to determine the correlation of these measures to…

Correction of nasal deformity in infants with unilateral cleft lip and palate using multiple digital techniques. Y Zheng, DP Zhang, T Qin, GF Wu.

Date: December 2015. Source: Journal of Prosthetic Dentistry. Abstract: Presurgical correction of severe nasal deformities before cheiloplasty is often recommended for infants with cleft lip and palate. This article describes an approach for the computer-aided design and fabrication of a nasal molding stent. A 3-dimensional photogrammetric system was used to obtain the shape information of…

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…
