Methodology for the use of realistic dento-models of the jaws for modeling dental treatment by the method of dental implantation, preparation for its stages and the development of methods for monitoring the stability of implants

The aim of the study is to develop a methodology for using realistic dento-models of the jaws, on which it is possible to reproduce specific clinical situations for teaching and modeling the stages of treatment by the method of dental implantation, as well as for preparing for implant treatment. A sample of a realistic dental model of the jaw was developed, made by 3D printing on the basis of a preliminary scan of diagnostic models of the jaws of real patients. The dento-model contains a bone fragment obtained from a pig's jaw by milling. The fragment is located in the area of the defect in the dentition in the alveolar process and thus imitates the bone tissue of the alveolar process of the human jaw. A study was carried out with the use of dento-models with the participation of 3 patients at the dental clinic of Ryazan State Medical University. To fully recreate clinical situations, the density of the bone tissue of the jaws of patients in the areas of dentition defects was determined in order to select the desired type of bone tissue from the pig's jaw for fixing its fragment in the models. All stages of dental implantation and further prosthetics with clinical and frequency-resonance control of the stability of the implants were implemented on the denture models. The study made it possible to establish that the bone tissue of the pig's jaw demonstrates a high similarity with the human jaw bone in composition and mineral density, which makes the use of the developed dento-models in training realistic. The presented denture models open up opportunities for testing various other innovative materials that simulate human bone and soft tissues, as well as provide clarity of physical, mathematical and mechanical methods for determining the stability of dental implants and their suprastructures, which can be a testing ground for the development of these technologies.
