Efficiency of use of bone augmentation materials based on multipotent mesenchymal stromal cells of adipose tissue before dental implantation in patients of study groups

Abstract

Objective. To determine the effectiveness of bone augmentation materials based on multipotent mesenchymal stromal cells of adipose tissue, which were used to fill bone defects during dental operations before dental implantation in patients of the study groups.Materials and methods. Examination and treatment with dental implants were performed on 140 patients who had previously undergone surgery to increase the bone volume of the alveolar processes of the jaws with the use of various bone augmentation materials. All patients were divided into three groups: I (main) group – 49 people (35.0%), in whom the material “Colapan–L” was used to restore the bone tissue of the alveolar processes; II (main) group – 62 patients (44.29%), in whom the augmentation of bone defects was performed using our proposed composition: the drug “Colapan–L”, multipotent mesenchymal stromal cells of adipose tissue and platelet-rich plasma; group III (control) – 29 patients (20.71%) in whom wound healing occurred under a blood clot (spontaneous).Results. It was found that in patients in whom a combination based on multipotent mesenchymal stromal cells of adipose tissue, the drug “Colapan–L”and platelet-rich plasma was used to fill bone defects, peri-implant tissues were completely restored after dental implantation.Conclusions. The effectiveness of our proposed osteoplastic combination based on multipotent mesenchymal stromal cells of adipose tissue, the drug “Colapan–L” and platelet-rich plasma in patients was confirmed by the positive dynamics of the periodontal index PMA, Schiller–Pissarev test. The use of bone augmentation materials based on multipotent mesenchymal stromal cells of adipose tissue during dental operations improves the regenerative and reparative properties of the bone tissue of the jaws, facilitates the postoperative course and reduces the duration of inpatient treatment of patients.
