Evolutionary analyses suggest that the difference in nose shape between EUR and EAS populations is caused by a directional selection, due mainly to a local adaptation in Europeans. Our results illustrate the underlying genetic basis for facial differences across populations.
The aim of this work is to evaluate the facial asymmetry in a group of patients with Class II subdivision, compared to patients in Class I without evident asymmetry, by using 3D photographs of the face.
The authors analyzed a number of metrics measured using 3D stereophotogrammetry following ESCH, an imaging alternative that is free of ionizing radiation and can be performed on awake children.
..the broad autism phenotype observed among first-degree relatives of autistic people is expressed not only in behaviour and cognition but also in facial characteristics.
The objective is to quantify the effect of sex on adult facial size and shape through an analysis of three-dimensional (3D) facial surface images.
Results show a significant improvement…and encourage the clinical use of 3D photogrammetry to reduce exposure to radiation of children.
Results of this study show that 3dMD photography is a valid alternative to CT for evaluation of head shape in MCS. Its use will provide an objective, quantifiable means of assessing outcomes in a rigorous manner while decreasing radiation exposure in this patient population.
Smile analysis in horizontally angled views is indispensable for esthetic assessment and could reveal teeth-to-lip disharmony, which might escape discovery in the frontal and profile views.
Complete denture and implant-supported fixed partial denture cause facial soft tissue changes, which may help to improve the facial esthetic.
Sixty volunteers (aged 18-45 years) were included, and standardized frontal view images were obtained by three-dimensional photogrammetry. Each image sequence frame was referenced and superimposed onto the neutral image.
