COMPUTER PROGRAM FOR SELF-ASSESSMENT OF PERI-IMPLANT TISSUE

Abstract

The subject of the study is a method for assessing the quality of implant prosthetics. The goal is to develop a method for patient self-assessment of the condition of peri-implant tissues. Methodology. Two computer programs developed at the Department of Orthopedic Dentistry of the First St. Petersburg State Medical University served as an analogue and prototype for the development of a visual analogue scale (VAS). acad. I.P. Pavlova: “KULOS” “Comprehensive assessment of the tissues of the prosthetic bed and the quality of dental and jaw prostheses” (Trezubov V.N. et al., 2008) and “PARMIT” “Automated portable visual analogue scale (VAS)” (Trezubov V.N. et al., 2023).Clinical testing of the developed scale was carried out. The study involved 48 people (11 men, 37 women) aged from 48 to 65 years (average age 58.2 ± 4.8 years). Statistical processing of materials was carried out using SAS v9.4 software. Results. This scale is intended for patients to self-assess the condition of peri-implant tissues. Completed by us as a questionnaire, it actually represents a six-step visual analogue scale – VAS. Successful initial clinical validation of the method was carried out. Parallel use of the questionnaire by Wolfart S. (2006) and Mericske-Stern R. et al. in the same patients. (2009), “PARMIT” (Trezubov V.N. et al., 2023) demonstrated a reliable general direction and an average degree of closeness of these questionnaires with the author’s method (respectively: r_1 = 0.468; r_2 = 0.573; r_3 = 0.698). Conclusions. A method for patient self-assessment of the condition of peri-implant tissues has been developed. The proposed method can be used in expert assessment of the quality of implant prosthetics.
