3M™ Filtek™ Z250 Universal Restorative is an esthetic, light-cured, radiopaque composite specifically designed for use in both anterior and posterior direct or indirect restorations. Bonding to the tooth structure is accomplished by using a dental adhesive system, such as 3M™ Single Bond Dental Adhesive or 3M™ Scotchbond™ Multi-Purpose Adhesive Systems.
The material is incrementally placed and cured in the cavity. The maximum cure depth for an increment is 2.5mm for most shades. Each layer is cured for 20 seconds. The exceptions to this are the B0.5, C4 and UD shades that should be placed in increments of less than 2.0mm. Each layer is then light cured for 30 seconds.
