Abstract: В работе проведён сравнительный анализ отечественного антропоморфного стоматологического робота (АСР) и международных аналогов. Предложены направления модернизации АСР: применение методов фотограмметрии для повышения точности оценки результатов выполненного студентом лечения, использование компактных вычислительных модулей nVidia Jetson для уменьшения габаритов установки и способ модификации пластиковых зубов для имитации эмали зубов человека. Достигнутые результаты модернизации позволяют организовать более качественную отработку клинических сценариев студентами-стоматологами. Introduction. Robotic simulators have become an integral component of contemporary dental education. To enhance training effectiveness, a domestic anthropomorphic dental robot was developed. To identify the required improvements to this platform, the capabilities of its foreign counterparts were examined. Comparative analysis made it possible to determine which additional functions should be incorporated into the anthropomorphic simulation robot (ASR) to improve the realism of dental-visit simulation. For each desired function, potential engineering solutions were identified and corresponding prototype models were developed. Objectives.The study aims at conducting a comparative assessment of the ASR relative to modern international analogs, to evaluate its competitive advantages, and to define scientifically grounded pathways for modernization. Methods. The research relied on theoretical analysis. The first part presents a comparative review of several medical robotic systems. The second part evaluates materials used for manufacturing dental phantom teeth. The third part analyzes camera-based measurement methods and assesses the feasibility of applying these techniques in the given setup. Findings. The analysis revealed core limitations of the ASR platform, primarily insufficient simulation of tooth preparation and limited accuracy of the assessment subsystem. To address these issues, several structural enhancements were introduced, including a water-collection system and a moisture- and contamination-protection system. Further evaluation showed that the existing object-measurement method was not optimal with respect to accuracy. As a result, components of a laser-scanning subsystem were integrated, and the required software was developed. Conclusion. The simulator’s performance improved, and user interaction became more consistent with treatment of an actual patient. Measurement accuracy increased from 0.5 mm in the previous system to 0.1 mm in the modernized design. The realism of simulation also improved due to the implementation of water cooling during tooth preparation, mirroring standard clinical practice.
