The LuxaFlow System is the first composite formulated specifically for use as an add-on resin for Luxatemp and other bisacryl provisional materials. LuxaFlow is ideal for blocking out undercuts and as a solution for enamel defects. It is also effective in creating a seal in the gingival interfaces. So you can use LuxaFlow to fill, build-up or repair almost any bisacryl provisional. Available in A1, A2, A3.5 and B1 shades.
