Design and multidimensional analysis of dental orthopedic prosthetics quality

The purpose of the research is a multidimensional analysis of the "quality of life" of patients before and after dental prosthetics. It is necessary to assess the quality of life of patients after prosthetics, depending on the type of prostheses, gender, and age of patients and give recommendations on the choice of prosthetics method. Methods. Dental prosthetics was performed at the clinic of the Moscow State Medical University named after A. I. Evdokimov, four types of prostheses were tested - the classic traditional prosthesis (TR) and three types of digital prostheses (D1, D2, D3). Based on the developed OHIP-20 DG questionnaire, the quality of life of patients was assessed before prosthetics, immediately after prosthetics and six months later. The quality of life of patients after prosthetics was determined within the framework of the theory of latent variables. Using a four-factor analysis of variance, the impact on the quality of life of the type of prostheses, the duration of adaptation after prosthetics, gender and age of patients was assessed. Results. Within the framework of the theory of latent variables, it is shown that the developed questionnaire can be used as a measuring tool to analyze the influence of the studied factors on the quality of life of patients after prosthetics. Due to the use of four-factor analysis of variance, the accuracy of statistical analysis has been improved and the statistical significance of four sources of variance has been revealed. Based on the results of statistical analysis, recommendations on the choice of prosthetics method have been developed. Conclusion. A multidimensional analysis of the studied factors affecting the quality of life of patients after dental prosthetics was carried out. The quality of life of patients increases statistically significantly after prosthetics. Due to the use of a four-factor model of variance analysis, the precision of assessments of the quality of life of patients has been improved. The prosthetics method (D1) is recommended for women, the prosthetics method (D3) is recommended for men. The obtained results are recommended to be used in practice.
