In the work the ef cacy of the adhesive dental restoration with different composites at monoaxial compression is tested. Deformation behavior of composite materials (SDR, Filtek P60, Filtek Ultimate Flowable, Filtek Ultimate) is compared in adhesive recording to a dentine at monoaxial compression. It is shown that mechanical properties of the composite materials are different because of their properties, but it is possible to predict their behavior in teeth after composite adhesive restoration. The highlled composites (to Filtek Ultimate and Filtek P60) are closer to dentine mechanical properties whereas the behavior of the lowlled composite materials (SDR and Filtek Ultimate Flowable) signi cantly differs from deformation behavior of a dentine.
