Evaluation of compressive strength and void content of resin based dental composites

Mesoporous, nanometric silica particles that can serve both as carrier and filler for fluoride were synthesized, and their release properties were later investigated. The flexural and compressive strengths performances of organic matrix and composite materials were evaluated using the tests defined in BS EN ISO 4049. From the Brunauer–Emmett–Teller results of the synthesized mesoporous silica particles, mesoporous SiO2 particles‐6 (MSP‐6) was preferred because it fits the MSP‐6 Type V isotherm model and has a highly mesoporous structure. The saturation points of MSP‐6 and R709 silica particles in terms of fluoride were determined as 180 min for MSP‐6 and 120 min for R709, respectively. The strength of composites prepared after the treatment of surface‐modified R709 silica particles with fluoride solution decreased, an increase was observed in the composites prepared after MSP‐6 particles were treated with fluoride solution. The porous silica particles caused a slight increase in the compressive strength of the composites. The standard deviations of the compression values of the fluorine‐containing composites F/R709 and F/MSP‐6 are quite low. The microhardness values of R709, F/R709, MSP6 and F/MSP6 samples were determined as 82.1 ± 8.59, 247.67 ± 12.32, 131.03 ± 10.98, and 218.8 ± 11.24, respectively. Especially considering the effect of chewing force the surface hardness of the composite is also directly related to the compressive strength. The increase in the compressive strength of the samples treated with fluoride confirms this result. A high rate of mesoporous structure silica particles was synthesized and could serve both as a carrier for fluoride and as a filler required by the material.

“…They then showed that polymerization shrinkage was reduced from 15.2% for compositions without filler to 8.2% for compositions with 9% inorganic filler by weight. 136 Moreover polyhedraloligomericsilsesquioxane (POSS) is a filler that is increasingly being used to improve the mechanical properties of such composites (POSS). The addition of POOS to the organic matrix can significantly reduce the risk of microleakage and secondary caries.…”

“…Dental composite materials mainly consist of the resin matrix, filler, coupling agent, and photoinitiator. Mechanical properties of dental composite material are greatly affected by filler, its size, and distribution in the matrix component [62, 71–77]. All the mechanical properties increased with an increase in filler concentration till they reached a threshold limit of filler concentration, and beyond this limit, the mechanical properties decreased due to a reduction in matrix‐particle adhesion strength [78].…”

Nowadays, there is a large variety of dental restorative composite materials on the market, making it difficult to select the proper one. The mechanical properties of various dental materials determine how long they endure when used in the mouth. On the other hand, the therapeutic efficiency of these restorative materials cannot be predicted solely based on their mechanical properties. These features, on the other hand, help with the examination of the impact of changes in their composition. As a consequence, these tests can help the clinician choose the right material. The various mechanical properties can be investigated using a variety of laboratory experiments. The common laboratory tests used to evaluate the mechanical characteristics, composition, and classification of dental composite materials, as well as the factors that influence mechanical qualities, are discussed in this study.
