Objective: to evaluate the efficiency of a resorbable membrane «Bio-Gide» in combination with chitosan for guided bone regeneration during the degradation under the experimental conditions. Material and Methods. The histological methods provide the study of tissue samples from 6 adult rabbits from artificial mandible through 14, 28 and 42 days after surgery. In group 1 the treatment was carried out without the use of additional materials, by a blood clot. In group 2 closing of the damaged area was produced by xenopericardial plate «Bio-Gide» in combination with chitosan. Results. It has been established that the conduct of bone wound under a blood clot causes inflammatory response on the 14th day after the operation, to the 28th day inflammation disappears and it practically does not appear on the 42nd day. Closure of the bone defect using xenopericardial plate «Bio-Gide» with chitosan causes lesser inflammatory response. In the long-term period after the surgery inflammatory changes in the implantation can not be detected. Conclusion. Xenopericardial plate «Bio-Gide» in combination with chitosan has a positive impact on the recovery process of the bone defect. Neoplasm of bone occurs, the stage of development of cartilage is shortened. At the end of the experiment period xenopericardial plate is not detected indicating the high rate of its biodegradation.
