3M™ Filtek™ Z250 Universal Restorative Dental Composite

 

Subcategory: Methacrylate; Thermoset

Material Notes:
3M™ Filtek™ Z250 universal restorative is an esthetic, light cured, radiopaque composite specifically designed for use in anterior or posterior direct or indirect restorations. 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 traditional syringes and single dose capsules.

The matrix of this composite is a resin consisting of BIS-GMA (Bisphenol A diglycidyl ether dimethacrylate), UDMA (urethane dimethacrylate), and Bis-EMA (Bisphenol A polyethylene glycol diether dimethacrylate). This light-cured resin is filled with 60% (volume) silica/zirconia. The filler particle size distribution is 0.01 µm to 3.5 µm with an average particle size of 0.6 µm.

Filtek™ Z250 exhibits about 18% less volumetric shrinkage upon curing than 3M™ Z100™. An example from the manufacturer shows shrinkage of 2.0% after 5 minutes and 2.2% after 30 minutes; sample geometry will effect actual values. Wet fracture toughness is 1.5 MN/m. The wear rate in an in-vitro 3-body wear test gives 3.6 µLoss/39,000 cycles.
