CLINICAL EFFICACY OF A METHOD FOR REPLACING BONE DEFECTS IN THE JAWS WITH THE POSSIBILITY OF TEMPORARY DENTAL PROSTHETICS FOR THE PERIOD OF INTEGRATION OF DENTAL IMPLANTS

The article is devoted to the clinical testing of the developed protocol of dental implantation surgery, including guided bone regeneration and temporary prostheses, for patients with complete edentulism and atrophy of the alveolar bone. The clinical testing of the proposed prosthetics technology involved 24 patients aged 55 to 72 years with complete absence of teeth and atrophy of the jaw bones. All patients underwent surgery according to the developed protocol. At the same time, 18 patients underwent dental implantation on the lower jaw on the day of surgery for installation of an individual titanium mesh for guided bone regeneration with the possibility of temporary prosthetics. A total of 260 dental implants were installed, 144 in the upper jaw and 116 in the lower jaw. The meshes were loaded with temporary non-removable orthopedic structures on the day of surgery. The effectiveness of dental implantation was assessed using cone beam computed tomography and resonance frequency analysis on the day of installation, during temporary and permanent prosthetics, and one year after surgery. As a result of the conducted research, it was found that the average increase in bone tissue in height and width of the upper jaw was 4.3 and 4.1 mm, respectively, and the lower jaw was 3.8 and 4.1 mm. The high stability of dental implants was noted both immediately after installation and under conditions of functional load. The assessment of the quality of life of patients in the study group was carried out both before surgery and during the postoperative period of 14, 30, 90 and 180 days. The results of the study showed that temporary dental prosthetics using non-removable structures based on individual titanium meshes made using 3D printing technology significantly improves all parameters of the quality of life of patients with complete edentulism.
