Sal de iodônio aumenta a resistência coesiva de uma resina adesiva experimental na presença de solvente

Abstract: Resumo: Este estudo avaliou o efeito da concentração de solvente na resistência coesiva de um adesivo experimental contendo um derivado do difeniliodônio. Uma blenda monomérica baseada em Bis-GMA, TEGDMA e HEMA foi utilizada como resina adesiva modelo. Foram avaliados dois sistemas de fotoiniciação: um sistema binário[canforquinona (CQ) e etil 4-dimetilamino benzoato (EDAB)] e um sistema ternário [CQ, EDAB e hexafluorfosfato de difeniliodônio (DPI)]. Nestas resinas foram adicionadas diferentes concentrações de… Show more

“…The conversion of methacrylate monomers is an important parameter to determine the final properties of the resin material. The presence of unpolymerized monomer can make the material more susceptible to hydrolytic degradation, leading to a poor durability [3,7,8]. In addition, higher polymerization rates decrease the time required for photo-activation during clinical application.…”

“…Although simplified adhesives have lower sensibility-technique, incomplete volatilization of the solvent can trigger a poor polymerization [19][20][21]. The excess solvent residual during the in situ polymerization may compromise the mechanical properties of polymer and therefore, the quality of the bonding interface [7,21]. Figures 2 and 3 demonstrates the effect of the solvent as a retarding agent for the polymerization reaction in photoinitiation binary systems.…”
