Abstract

The comparative experimental study of osseous tissue regeneration in the createdforaminous mandibular defects being implanted with bioceramics Kergap T-300 and osteoplastic material Osteopor, as well as justifying the possibility ofusing the developed reparative material in the maxillofacial surgery clinics based on the analysis ofhistomorphological research results for are the paper objectives. 78 nonlinearwhite male rats weighing 240-300 g withforaminous mandibular defects were used as models for studying impact on the reparative osteogenesis processes made by the bonegraft material. Reparative changes in the implantation sites were studied in real time with the help of histological drugs under the optical microscopy. The graft components were the morphometry object calculated at the percentage ratio per the graft space unit in three cuts from each section. In 27.7% cases the rats'mandibular defects repair under the natural environment conditions of osseous tissue regeneration achieved with a blood clot was complicated by purulence, the surgical wound dehiscence with pyorrhea or perimandibular abscess. In other cases regeneration caused the development of heterogeneous graft made of chondroid-fibroblastic and osteoid tissues ...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
