Elastic modulus of dental filling composites: Different determination methods.
Original language description
Materials for dental cavity filling such as amalgam and alloy were replaced by composite filling and ceramic inlay. Our team-work was focused on dental filling composites investigation with a view to prolong lifetime and minimize probability of failure.The most common failure types were filling fractures, secondary caries and losses of filling. Main reason for failure was stress incidence in filling and adhesive layer causing failure of tooth-adhesive-composite interface. Magnitude of the stress depended on many factors such as shrinkage of composite during polymerization, occlusal loading, cavity shape and method of cavity filling. Stress value could be mathematically analysed using finite element program. This analyses required knowledge of exact material properties. The goal of work was to determine values of composites Young's modulus by different experimental method: simple tensile test, three-point bending test, nanoindentation test and ultra-sonic test.
