The combinations of variants of the structure of the bony palate with different forms of the skull in the context of age-related dynamics of craniometric parameters

The bonal palate is an anatomical structure that provides the strength of the force buttresses of the facial skull and allows the pressure created in the chewing apparatus to be evenly distributed across the gums. At the same time, its shape is interrelated with the configuration of the dentition and is closely involved in the formation of anomalies of the teeth-jaw system, and, first of all, the occlusion. The study of the relationship of various forms of the skull with the forms of the bony palate and the age-related dynamics of cranio-metric parameters at different ages is one of the important tasks facing clinicians and morphologists. The aim of the study was to study the age-related dynamics of craniometric parameters and options for combining the anatomical forms of the skull with the anatomical forms of the bony palate. Age parameters were studied on 120 skulls of people of different ages from the craniological collection of the fundamental museum of the Department of Human Anatomy and Medical Terminology of the Azerbaijan Medical University. A comprehensive study was carried out, the essence of which was to measure the craniometric and morphometric parameters of the skull and bony palate and to comparing evaluate them. The superscript of the face, the transverse-longitudinal index of the fornix and base of the skull, and the transverse-longitudinal index of the bony palate were studied. The original method was used to study the dimensions between non-standard points. The non-standard points were the inner edges of the maxillary alveolar ridge at the level of the upper canines, as well as at the level of the second premolars and molars. Analysis of the data obtained showed that age-related changes are not always detected in the parameters of the cranial vault. The coefficients of variation of the cranial width and upper face height were higher than those of the cranial length and zygomatic diameter. Mesocranes and mesobasillaries prevailed in all forms of the bony palate. Leptenes were more often combined with leptostaphily, and eurenas with brachistaphily. Eurenas are not found in leptostaphily, and leptens in brachistaphily. Compared to brachycrans, brachybasillaries were found to be more compatible with leptostaphily. The results of the study indicate the presence of a certain relationship between the shape of the skull and bony palate with age-related dynamics of craniometric parameters.
