В развитии асептического некроза головки бедренной кости большую роль играет совокупность факторов, включающие в себя как нсйрососудистыс нарушения, особый гормональный фон, влияние окружающей среды, так и особенности строения тазобедренного сустава в биомеханическом плане. Процесс перестройки, лежащий в основе любых изменений формы и строения кости, зависит не только от состояния кровоснабжения, но и от условий функциональной нагрузки. Эти два фактора совместно приводят к активизации процессов перестройки кости.
Переломы бедренной кости у детей относятся к тяжелым повреждениям, встречаются довольно часто и лечение их представляет до сих пор нелегкую задачу. Поэтому изучение этого вопроса имеет большое социально -экономические значение.
Дизайн поверхности имплантатов эволюционировал для решения проблем реабилитации полости рта как в здоровой, так и в нарушенной кости. Например, чтобы победить наиболее распространенные осложнения, связанные с зубными имплантатами, периимплантит и последующую потерю имплантата, поверхности имплантатов были модифицированы, чтобы придать зубному имплантату желаемые свойства и тем самым повысить процент успешного приживления имплантата и расширить показания к их применению. Биоактивные покрытия имеют потенциал для улучшения костной интеграции механически нагруженных ортопедических керамических имплантатов. Есть гипотеза о том, что биоактивное покрытие будет способствовать интеграции отменной кости. Биоактивное покрытие замедлить скорость коррозии сплавов и ускорить процесс заживления кости. Основная Цель биоактивных покрытий - усилить прямое прикрепление живых тканей и тем самым способствовать остеокондукции.
Челюстно-лицевой рост - представляет собой комплекс процессов, состоящий из достаточно большого количества взаимодействий различных типов кости, которые составляют череп, кроме этого твердых и мягких тканей. Процессы, которые контролируют рост и развитие челюстнолицевого комплекса не вполне изучены и в настоящее время являются областью интенсивного исследования во всем мире.
