Because Ribbond also bonds to acrylic and bis-acryl, it is commonly used for making
reinforced provisional bridges. For longer-term bridges, multiple
layers of Ribbond make a strong stress bearing laminate structure
to act as a framework. For simple provisionals, one piece is commonly
used to prevent cracks from propagating through the resin past the
Ribbond. Although a crack may start, the Ribbond prevents catastrophic
failure and maintains the integrity of the bridges.
