Description
Summary:Currently, composite materials dominate among the restorative materials used for direct aesthetic filling. Reinforcement of composites with glass fibers allows for the transfer of greater loads and better durability between the tooth tissue and the filling polymer. New approach to bonding liquid materials with composite with glass fillers is to introduce an additional protective barrier to load a higher force that is, compression test. So, the aim of the study was to analyze the structure of composite fillings, their integrity with tooth tissues and evaluation on the influence of the liquid composite layer on the strength of strength in the compression test. Moreover, the influence of thermal shocks on the bonding with the tooth tissues in the compression test was investigated. According to the results obtained in current research, using the flow composite as a combination with the fiber composite leads to a significant increase in mechanical properties, particularly in the compression test. Highlights If flow‐type composite fluid material are, the greater is strength of composite fillings. Glass fibers composite increase the mechanical strength. Compression test in dentistry composite fillings.
