Purpose: The application of polymeric materials for medical purposes is growing very fast. Polymers have found applications in such diverse biomedical fields as tissue engineering, implantation of medical devices and artificial organs, prostheses, ophthalmology, dentistry, bone repair and many other medical fields. The requirements for materials used in the construction of removable dentures are becoming more and more demanding. The introduction of improved flexible materials has been a considerable advance. The aim of this work was to determine how the properties of thermoplastic materials change over time in terms of weight changes and artificial saliva sorption. Purpose of this paper was to evaluate the influence of the ageing process on mechanical properties of polyamide - glass composites applied in dentistry. Design/methodology/approach: Polyamide samples about the diversified content of the glass fibre were produced with method of the injection moulding. Denotation of the absorbency of artificial saliva was performed on standardized samples according to the norm. Samples were dried up to fixed mass, and then they were soaked in artificial saliva. Two temperatures of examination were applied 23°C and 30°C. Findings: An influence of the absorbability on mechanical properties of composites was determined. Examinations allowed to show that the absorbency of artificial saliva through composite is dependent on the temperature. Research limitations/implications: To fully evaluate the influence of the ageing process on mechanical properties of polyamide - glass composites applied in human body environment it is planned to continue described research. Simultaneous influence of the ageing process on mechanical properties of polyamide - glass composites shall be tested. Originality/value: Applying strengthened thermoplastics with glass fibre on dentures is a new look at materials applied in dentistry.
