--- The purpose of this study is to compare compressive strength and nanohíbridas microhybrid composite resins. The compressive strength is an important mechanical property of the resin due to the large load to be borne chewing during mastication, ie can withstand both compression to the point of fracture, so ideally find high compression values under technology advances filling resins, currently not fully clarified the issue because although most research states that there is a relationship between the type of filler composite resins and mechanical properties there is no clear explanation of how they might be related. The comparative analytical study is cross. The sample consisted of 15 cylinders each type resin (TPH Spectrum micro-hybrid 1, 1 Z250 microhybrid resin, resin 1 and 1 TPH3 nanohíbrida nanohíbrida resin Z250 XT) of 4 mm in diameter and 8 mm in height, being A total of 60 samples, before being taken to the universal testing machine AMSLER where they measured the compressive strength. The results are organized in tables using descriptive statistics, finding averages, medians, maximum and minimum, plus the Student t test statistics and Mann-Whitney test to compare the compressive strength between groups microhybrid resin and resin between nanohíbrida , all with a confiance level of 95%. Concluded that if there are significant differences in compressive strength resin TPH microhybrid microhybrid SPECTRUM with resin and with Z250 and Z250 TPH3 nanohíbridas XT. Obtaining as a result that the compressive strength of the TPH microhybrid resin was higher than SPECTRUM microhybrid TPH3 nanohíbridas Z250 and Z250 and XT, whereas the last 3 groups mentioned above showed compressive strength like. -- Keywords: compressive strength, micro-hybrid composite, composite nanohíbrida.
