Belarusian scientists working over 3D jaw model for correct implant placement

Scientists from the Belarusian State University (BSU) and the Belarusian State Medical University (BSMU) are developing a biomechanical 3D model of a lower jaw, a temporomandibular joint, and an upper jaw for correct implant placement, prevention of the consequences of bruxism, and other pathologies, sb.by reports with reference to the educational institution’s press service

The research is conducted by Sergei Bosyakov, the Dean of the BSU Faculty of Mechanics and Mathematics, and Dmitry Nazarenko, a junior researcher at the BSU Research Laboratory of Applied Mechanics. In addition, BSMU Rector Sergei Rubnikovich and the Head of the BSMU Department of Orthopaedic Dentistry and Orthodontics, Arseny Grishchenko, are engaged into the work.

In early 2023, the first results of the development of a 3D lower jaw model were obtained, and the models of an upper jaw, a temporomandibular joint, upper and lower teeth, and periodontal ligaments are ready now – thus creating a virtual digital double.

“A 3D model is a revolution in the field of dentistry, and it has no analogues,” the source reported. “The unique development will enable medical professionals to adjust implantation indicators, determine implant stresses in various pathologies, plan surgical operations, and prepare recommendations for practicing surgeons.”

As informed, a virtual model will help create a personalised model of the patient's jaw based on the tomography results. In addition, the development will make it possible to carry out preliminary calculations for implant placement in order to avoid its subsequent instability or other disorders. The introduction of a 3D model will also contribute to the development of approaches to the treatment of various defects of the upper and lower jaws.

“BSU scientists have performed mathematical calculations that revealed the effect of the thickness of the mucous membrane on the load of dental implants,” the source added. “The load, the conditions of the study and the obtained indicators are analysed together with medical specialists for compliance with the real chewing load.”

The influence of the location of food products during chewing on different areas of a lower jaw has been studied as well, and the obtained results will make it possible to prepare recommendations for doctors and patients.

As reported, it is planned to automate the model generation and personalise it for patients, and tests are currently being carried out to study the effect of the action of various muscle groups in bruxism and other deviations from the norm.
