Influence of biological relatedness on human palatal form and shape
Vilímková, Eva ; Velemínská, Jana (advisor) ; Borský, Jiří (referee)
This diploma theses deals with the effect of biological relatedness on the morphology of the human palate. So far, the effect of heredity on the morphology of the palate has been studied mainly in connection with clefts, there are not many studies dealing with the morphology of a healthy palate. Within this work, two goals were set. The first was to evaluate the variability of the palatal morphology of biologically related individuals compared to the variability of the palatal morphology of unrelated individuals. The second goal was to evaluate the effect of biological relatedness on palatal morphology. The material for this theses were two samples - a sample of biologically related individuals and a sample of unrelated individuals as a control group. The genealogically documented sample consists of 65 plaster casts of the upper jaw of mutually related individuals of the Czech population. This sample includes 33 men and 32 women. The average age in the sample is 37,65 years. The sample of unrelated individuals includes 52 virtual 3D models of a hard palate. This sample consists of 23 men and 29 women. The average age in this sample is 19,27 years. This theses combines methods of geometric morphometrics and linear regression models. The plaster casts of the upper jaws were first scanned with a 3D...

Modelling of human palate surface development from 7 years to adulthood
Moravec, Tomáš ; Bejdová, Šárka (advisor) ; Zemková, Daniela (referee)
The diploma thesis deals with the differences in the development of the palate in girls and boys within five age groups in the age range of 7 to 19 years, using methods of geometric morphometry. Furthermore, the work deals with the monitoring of sexual dimorphism in the development of the palate. Understanding palate growth, knowledge of differences in its development and changes related to sexual dimorphism are very useful, as the results of this study will serve as a comparative standard for palate defects in the Czech population, but also for appropriate planning of orthodontic procedures. The material consists of 228 gypsum castings of palate without any pathologies, 112 of which belonged to boys and 116 girls of the Czech population. Thus, transverse data are used in our study. The subjects were divided into five age groups 7, 10, 12, 15 and 19 with respect to gender. Age changes of the entire palate surface were modeled using geometric morphometry methods (Coherent point drift - Dense correspondence analysis, Per vertex T- test and Principal component analysis). To visualize the results, superprojection color maps, maps of significance and superprojection. The results show the greatest variability in the form of palate in girls of groups 10 and 12 years and in boys of groups 10 years, and...
