METHODOLOGY FOR CONSISTENT COPYING OF THE OVERDENTURE RESTORATION PARAMETERS FOR DENTAL IMPLANT PROSTHESIS IN THE TREATMENT OF TOTAL EDENTIA

THE AIM OF THE STUDY: Development of a technique for transferring the parameters of a temporary removable prosthesis to a permanent prosthesis based on dental implants. Examination and complex treatment of 55 people with complete loss of teeth were carried out. In the I-study group of patients (n = 30), the treatment was carried out according to the developed prototyping method, in the control group II (n = 25), the patients were treated using the standard method: after the implants were opened, the central ratio of the jaws and the setting of the teeth were re-determined. The transfer of the parameters of the removable prosthesis to the temporary crowns was carried out using an individual tray made by 3D printing. One-jaw prosthetics were performed in 45 patients, and 10 patients received prosthetics on both jaws. In the study group, where prosthetics were performed according to the developed prototyping technique, the number of visits for the manufacture and subsequent corrections of temporary crowns was significantly less than in the control group, and the number of days of adaptation of the patient to temporary crowns also decreased. Treatment of patients with complete absence of teeth using the developed prototyping technique made it possible to increase the accuracy of the manufacture of temporary prostheses based on dental implants, made it possible to shorten the time of prosthetics, reduce the time of adaptation to the prosthesis and achieve high aesthetic results, which makes this technique promising.
