3M™ Z100™ restorative is an all purpose, esthetic, light cured dental composite. 3M Restorative Z100 features a translucency and opalescence similar to that of natural teeth and is used for porcelain repair and metal masking. Bonding to tooth structure is accomplished by using a dental adhesive system, such as 3M™ Single Bond or 3M™ Scotchbond Multi-Purpose Adhesive Systems. The restorative is available in a variety of shades and is packaged in syringes or capsules. The matrix of this composite is a resin consisting of BIS-GMA (Bisphenol A diglycidyl ether dimethacrylate) and TEGDMA (tri{ethylene glycol] dimethacrylate). This light-cured resin is filled with 66% (volume) silica/zirconia. The filler average particle size is 0.6 µm. Filtek P60 exhibits higher volumetric shrinkage upon curing than 3M™ Filtek™ P60 or Filtek™ Z250. An example from the manufacturer shows shrinkage of 2.4% after 5 minutes and 2.6% after 30 minutes; sample geometry will effect actual values. Wet fracture toughness is 1.3 MN/m. The wear rate in an in-vitro 3-body wear test gives 2.2 µLoss/39,000 cycles. Compared to other dental composites, it has a medium-high diametral tensile strength, medium-high compressive strength, high compressive modulus, medium-high flexural strength and a high flexural modulus.
