Тype II Osteoporosis Pathogenesis as a Result of Secondary Edentulous.

      Аннотация: The main problem of women and elderly people of both sexes nowadays is osteoporosis. The widespread consequence of osteoporosis is cervical hip fracture that brings down quality of life and is difficult to treat especially if old people are affected. According to statistics 10-20% of people with cervical hip fracture die within half a year, 50% never regain full activity of the joint and they cannot walk without help, and 25% demand constant care. Bones of old people are more fragile especially in the places where there is more of spongy substance. With aging the ratio of soluble and non-soluble collagen significantly changes in favour of the last one. As a result old people get fractures more often. We should understand that bones in the adult age reach the peak of bone mass that starts to decrease with age. All these factors bring to decrease of thickness of bone and its destruction doesn’t depend on their combination. Therefore, our objective was to study the changes in the alveolar bones of elderly people in secondary edentulous.
