About Study Course

Objective

To develop competence of the students of the Faculty of Dentistry in the field of biomaterial science, providing theoretical knowledge and skills that will be acquired during lectures and practical classes and will be necessary for the acquisition of other study disciplines and dental practice.

Preliminary Knowledge

Knowledge of mathematics, physics and biology within the scope of a secondary school course.

Learning Outcomes

Knowledge

1.Students will acquire theoretical knowledge about the structure and physical properties of crystalline substances, metal alloys, polymers and composites; about the resistance of materials, biomechanical properties of biological tissues and methods for the determination of physical properties of biomaterials.

Skills

1.Students will be able to use: concepts of biophysics and regularities in solving medical and biological tasks; regularities of deformation theory for comparative characterisation of mechanical properties of various biomaterials, as well as predict behaviour of biomaterials under influence of various factors (at static and dynamic load, change of external factor parameters).

Competences

1.Will acquire theoretical and practical knowledge in biomaterial science, will be able to apply these methods in study, professional and research practice.
