Ali N. Тhe peculiarity of chewing pressure distribution in post systems.

The dissertation is devoted to questions of the peculiarity of chewing pressure distribution in post systems. For the first time is investigated the hardness characteristics of roots teeth hard tissue on Brilo and Vickers by the device ТК-2, and is determined that, the hardness and durability of the multiroot teeth approximately on 12,5% are less than one-root teeth. For the first time is investigated the peculiarity of chewing pressure distribution in post systems by determined the inertia and resistances on chewing pressure. The development of technical designs method for post systems constructors, which gave optimum clinical efficiency in created the new post designs. For the first time has been offered the chewing pressure classification, which make possibilities to optimum choose of post. The offered systematic help us to improvement the diagnostics, and choice of the most rational methods of treatment. On the basis of the concept and results of researches, designed the new variant of post, whichis introduced in practice after proving the efficiency by mathematical modeling. Designed the special nib drill for tissue teeth preparation for using the new post.
