Modern methods of 3D diagnostics and prototyping in temporomandibular joint reconstruction

This is the authors' abstract. We don't add key points for this paper.

This study presents the result of work using an optimized approach to preoperative planning and prototyping during TMJ replacement. The purpose of the study was to substantiate the need for the use of 3D technologies at the planning stage of surgical joint reconstruction. To achieve this goal, we analyzed the treatment data of 90 patients, who were divided into 2 groups. In the first group (n = 60), patients underwent preliminary planning followed by the manufacture of individual endoprostheses and templates, while the data in the second group (n = 30) were obtained through a retrospective analysis of medical records (no planning was carried out, stock endoprostheses were used). Pain, mouth opening, and quality of life scores were used for comparison. Data analysis supports the use of three-dimensional planning and manufacturing of individual endoprostheses and templates when performing temporomandibular joint replacement.
