Mondial i and Mondial denture teeth from HERAEUS KULZER are made from NanoPearls® filler material, which combines unique micro fillers and nano particles to deliver color stability and resistance to fracture, abrasion and plaque. Independent abrasion studies conducted at the University of Heidelberg and the Charité hospital in Berlin and Tufts University revealed a 50% higher abrasion resistance for NanoPearls materials compared with conventional PMMA acrylic materials.
