The aim of the work is to study barrier properties of collagen membrane “Osteoplast” (“Vitaform”, Russia) in closing critical bone defect in an experiment.
Materials and Methods. The experiments have been carried out on 20 rabbits of “chinchilla” breed.
Results. “Osteoplast”, a membrane made on the basis of bone collagen, is reabsorbed and serves as a safe barrier for fibroblasts migration into bone defect area. Its application enables to protect the defect area from fibrous tissue penetrating and initiate bone regeneration. Osseous tissue beneath a membrane goes few differentiation stages, has classical structure including all structural elements (osteons, lacunes, blood vessels) that provides its perfect strength characteristics.
