Ivocerin is a new germanium-based light-initiator developed by Ivoclar Vivadent and used exclusively in Tetric EvoCeram Bulk Fill. This new initiator allows Tetric EvoCeram Bulk Fill to cure faster and deeper than other composite materials without increasing translucency or reducing working time. The absorption spectrum of Ivocerin fills the “gap” between traditional light-initiators (e.g., Lucerin TPO, PPD, Camphorquinone) used in today’s most popular composite materials. It not only cures fast, but it cures well beyond the 2 mm limit of traditional initiators, achieving an efficient depth-of-cure at 4 mm.
With Ivocerin, Tetric EvoCeram Bulk Fill can be cured in layers of up to 4 mm in just 10 seconds (using a light with minimum output > 1,000 mW/cm2). Additionally, because Tetric EvoCeram Bulk Fill contains a shrinkage stress reliever, the shrinkage stress distributed along cavity walls and surfaces, and shrinkage volume experienced during polymerization, are exceptionally low.
Tetric EvoCeram Bulk Fill also features layered silicates for a smooth consistency that adapts well to cavity walls and can be applied and contoured easily with conventional dental instruments. No additional equipment is required. Restorations are polished quickly and easily due to the material’s well-balanced filler composition. The three universal shades (IVA for slightly reddish teeth; IVB for slightly yellowish teeth; and IVW for quick deciduous fillings or light-colored teeth) demonstrate an enamel-like translucency of 15%, so restorations blend seamlessly with natural dentition. Yet, the material demonstrates high radiopacity for easy detection on dental x-rays.
