To investigate chemo-mechanical effects of incorporating alkaline bioactive glass nanoparticles into a light-curable dental resin matrix.An unfilled Bis-GMA/TEGDMA material was infiltrated with up to 20wt% of ultrafine SiO 2 –Na 2 O–CaO–P 2 O 5 –Bi 2 O 3 particles. The unfilled and filled resins were investigated regarding their viscosity before setting...
Light-curable polymers are commonly used in restorative surgery, prosthodontics and surgical procedures. Despite the fact of wide application, there are clinical problems due to limitations of blue light penetration: application is restricted to defects exposed to the light source, layered filling of defect is required.Combining photo-activation and up conversion allows efficient polymer hardening...
