Evaluation of the effectiveness of orthopedic treatment with fixed prostheses made using digital and traditional technologies

Abstract

The aim of the study was to conduct a clinical assessment of the effectiveness of orthopedic treatment with fixed prostheses made using digital and traditional technologies. The clinical study involved 103 patients (52 men and 51 women) aged from 29 to 70 years. The patients were divided into two groups. The first group consists of 54 patients (28 men and 26 women) aged from 29 to 70 years, whose orthopedic treatment was carried out with non-removable metal-ceramic prostheses made using digital technologies. The second group consists of 49 patients (24 men and 25 women) aged 33 to 70 years, whose orthopedic treatment was carried out with non-removable metal-ceramic prostheses made using traditional technologies. The evaluation of the results of orthopedic treatment was carried out 1 year after the reinforcement of the prostheses with cement based on the criteria of the modified USPHS test for the clinical assessment of the condition of non-removable prostheses. The results obtained allow us to conclude that the technologies of intraoral laser scanning, computer modeling and automated production, in comparison with traditional technology, allow us to obtain fixed orthopedic structures with a shorter period of getting used to the prosthesis, better edge fit quality, preventing the development of secondary caries, and prevent the cementation of prostheses (p<0,005).
