Биомеханическое описание структуры костных тканей зубочелюстной системы человека

Abstract

The influence of variable biomechanical pressure on shape of the human mandible is considered in this paper. it is shown that bone tissue structure of the maxillodental system responds to changed conditions of loading as a result of both functional trauma and parodontosis. the age-related changes of cancellous and compact bone tissues of the body of the mandible determined by biomechanical pressure are investigated. the fabric tensor H is used for quantitative description of cancellous bone structure. the example of its construction is given. it is concluded about necessity of construction of a kinetic equation for the fabric tensor H at statement of the biomechanical boundary problems of the maxillodental system.

В работе рассмотрено влияние изменяющегося биомеханического давления на форму нижней челюсти. показано, что структура костных тканей зубочелюстной системы реагирует на измененные условия нагружения как при функциональной травме, так и при заболевании пародонта. изучены возрастные изменения трабекулярной и компактной костных тканей тела нижней челюсти, определяемые биомеханическим давлением. для количественного описания структуры трабекулярной костной ткани использован тензор структуры (fabric tensor) H. приведен пример его построения. сделан вывод о необходимости формулирования кинетического уравнения для тензора H при постановке краевых задач биомеханики зубочелюстной системы.
