It promotes a rapid cure in thin set applications. Polymer Concrete, which is concrete with Concrete Polymer Liquid added, is designed to combat the shortcomings of regular concrete particularly its low flexural strength and thin section fragility. When added to Portland cement, sand and water in specified proportions it creates a new flexible, adhesive cementitious compound which can be used to repair and protect a variety of surfaces. Within the limitations of this in vitro study, the incorporation of glass fibers and the presence of a foundation restoration were found to increase the fracture resistance and can favorably influence the fracture mode.Concrete Solutions Concrete Polymer Liquid is a special formulation of water-based resins specifically designed to be mixed with water, cement and sand mixtures.
Eight vertical root fractures occurred in group FR-NFRC, six in group NFR-NFRC, four in group NFR-FRC, and none occurred in group FR-FRC. Statistically significant differences were detected between the pairs NFR-NFRC/FR-FRC (p = 0.001), NFR-FRC/FR-FRC (p = 0.001), and FR-NFRC/FR-FRC (p = 0.001). The least fracture-resistant group was NFR-FRC, exceeded by FR-NFRC, NFR-NFRC, and FR-FRC, in that order, with FR-FRC being the most fracture-resistant group. The level of significance was set at ɑ = 0.05.Īll specimens successfully completed the fatigue test. Differences in means were compared using two-way ANOVA and Tukey's test. All specimens were subjected to mechanical loading in a computer-controlled masticator and then the fracture resistance was evaluated. NFR-NFRC and FR-NFRC groups were restored with composite resin overlays, whereas NFR-FRC and FR-FRC groups were restored with fiber-reinforced composite resin overlays.
In the NFR-NFRC (no foundation restoration, no fiber-reinforced composite) and NFR-FRC (no foundation restoration, fiber-reinforced composite) groups, only a 5-mm-thick composite resin layer sealed the pulp chamber floors, whereas in the FR-NFRC (foundation restoration, no fiber-reinforced composite) and FR-FRC (foundation restoration, fiber-reinforced composite) groups, a 3.0-mm foundation restoration was used. To evaluate the fracture strength and the failure mode of endodontically treated teeth restored with composite resin overlays with and without glass-fiber reinforcement.Ī total of 32 extracted molars were divided into four equal groups.
