RESULTS OF APPLYING X-RAY INVESTIGATION METHODS IN PATIENTS AFTER BONE DEFECT RESTORATION BY OSTEOPLASTIC MATERIALS USING CELLULAR TECHNOLOGIES

Abstract

The results of applying X-ray investigation methods to confirm effectiveness of the developed osteoplastic combination including multipotent mesenchymal stromal cells of adipose tissue, which was used to fill bone defects in operated patients, have been elusidated. Participants and methods. The study was conducted at the Department of Surgical Dentistry and Maxillofacial Surgery, Bukovinian State Medical University, Chernivtsi, Ukraine. To determine the density of bone tissue, CT scanning was done for 26 patients when replacing the bone defect with «Kolapan–L» (group A), for 28 people during the augmentation with an osteoplastic combination containing multipotent mesenchymal stromal cells of adipose tissue (group B), and for 25 patients where bone defect healing occurred spontaneously (group C). The study was conducted after the surgical operations (in 3-5-day, 3-, 6-, 12-month follow up period. We have found out the patients of group B who received the preparation «Kolapan–L» to fill bone defects in combination with multipotent mesenchymal stromal cells of adipose tissue and platelet-rich plasma demonstrate completed osteoregeneratis with newly formed bone tissue without granules of osteoplastic material in 6-8 months after the surgical intervention. In the patients of group A, who received the preparation «Kolapan–L» to replace bone defect, a complete osteoregeneration was observed in small and medium defects in 6-8 months, and more pronounced outcomes (more than 2.0 mm) were seen in 12-16 months. In the patients of group C (spontaneous healing), small bone defects were observed after 9-11 months the healing, while significant defects showed no complete tissues regeneration even in 12 month period. The results have demonstrated that in 12 month period, the patients of group B have the average density of osteoregenerate equalled 1036,69±55,53 HU that is 1.5 times and 1.8 times more than those values in the group A, p<0.01, and in the group B, p<0.05, p1<0.01, respectively.
