COMPARATIVE CHARACTERISTICS OF THE MORPHOMETRIC PECULIARITIES OF THE STRUCTURE OF BONE TISSUE OF THE DENTOALVEOLAR SEGMENTS OF MAXILLARY PREMOLARS

The morphometric parameters of bone tissue structure were studied in 168 dentoalveolar segments of maxillar premolars relative to the conventional median vertical median line. It was found that height, width and area indices were not significantly different in the 1st and the 2nd premolar dentoalveolar segments. At the same time, the dependence of the thickness of compact and cancellous bone on the side (vestibular, palatal) and part (upper, middle, base) of the segment was detected. It was also found that while the thickness of the compact substance increased from the upper part of the segments toward the base independently on their part, the thickness of the cancellous substance, conversely, was significantly decreased on vestibular side, and was increased on the palatal side.
