title: [MORPHOLOGICAL CHARACTERISTICS OF OSSEOINTEGRATION AFTERAPPLICATION OF TITANIUM IMPLANTS WITH BIOACTIVE COATING AND RECOMBINANT BONE MORPHOGENETIC PROTEIN].
abstract: Experiments were carried out on 22 albino male Wistar rats to study the morphological peculiarities of osseointegration of titanium grafts with bioactive surface stimulated additionally with bone plastic material "Gamalant-paste-FORTE Plus" containing recombinant human bone morphogenetic protein-2 (rhBMP-2). In 9 rats the implants were placed into femoral bones after local treatment of bone canal with rhBMP-2-containing material. Another 9 animals were implanted but received no treatment, 4 rats formed the group of intact control. Zone of osseointegration was studied 4, 8 and 12 weeks after graft placement using histological and morphometric methods as well as immune histochemistry to demonstrate osteonectin, CD68, MMP-9, and TIMP-1. The study showed that preliminary treatment of bone canal with rhBMP-2-containing material preceding implant placement was accompanied by an additional osteoinductive effect. More intense and outrunning bone formation in the area of osseointegration was observed, together with remodeling and compaction of the contiguous cancellous bone, thus providing the necessary balance between MMP-9 and TIMP-1 with a high level of each factor expression.
