Abstract:
Dental materials usually contain an organic and inorganic part. The organic phase is a mixtures of mono- and multifunctional monomers called resin. The inorganic part which percentage is about 60 percent shall allow the optimal mechanical properties for the requirements of dental materials. The main problem is the volumetric shrinkage of resins. Nanoparticles with reactive vinyl groups have potential use as dental materials. In this work we have investigated the mechanical properties, volumetric shrinkage and viscosities of NCs. The size of nanoparticles as organofillers in swollen state was determined by dynamic laser light scattering (DLS) method and the dried form by scanning electron microscopy (SEM). Structures and reactivity of polymers were detected by nuclear magnetic resonance. (H NMR)
