Three-dimensional assessment of the relative contribution of genetics and environment to various facial parameters with the twin method

Alternatives to Radiation Investigations in Orthodontics

“…There is now a fast moving trend towards 3D imaging and indeed the lateral cephalometric may phase out in years ahead. In orthodontics there is a strong association between form and function 110 . This has been studied extensively and proved with strong correlation that exists between the soft tissue and underlying osseous foundation.…”

Analyzing Facial Esthetic and Divine Proportion From Orthodontics Perspective

“…Achieving esthetics is the most important objective of the modern orthodontics; thus, analyzing the divine proportion on the soft ratio can be a good standard to assess an orthodontic treatment, because in many cases analyzing the hard tissue may reflect some deviations from the normal form, but it has been covered with the soft tissue (15,16 The age group of subjects in this study was 19 to 26 years, whose growth age has been almost completed, because as we know the adolescence and puberty time would be associated with many changes in the facial proportion, especially in nose and lower jaw. Only female subjects were selected to limit the scope of the variables in the study and also decreased the dilution of results.…”

Who Do I Look Like? Determining Parent-Offspring Resemblance via Gated Autoencoders

“…Although humans can perform this job at a rate higher than chance, it is not clear how they do it [2]. However, recent studies in anthropology [24] have determined which features tend to be the most discriminative. In this study, we aim to not only create an accurate system for resemblance detection, but bridge the gap between studies in anthropology with computer vision techniques.…”

“…Anthropologists have tried to answer this question with quantifiable measurements for years. In [24], Naini and Moss claim to have cracked the code finding the most meaningful genetic features in determining relatedness. Further studies [2,5,6], claim to have correlated visual resemblance between parents and their offspring of varying ages.…”

“…Past anthropological studies have not only analyzed familial relationships, but more specifically the relationship between twins [7,8,20]. Naini and Moss [24] specifically compare facial features across 3D scans of dyzogotic and monozygotic twins. This twin method allows finding which features are genetic vs. environmentally influenced.…”
