summary A novel test procedure was developed that provides the basis for a standard plain strain fracture toughness test to evaluate fracture resistance of resin‐based materials. This procedure utilizes a notched disc specimen. Using this technique, a new concept of‘Torque to initiate fracture (T)’was suggested. Also, fracture resistance can be assessed by means of critical stress intensity factor ( K 10 ). Using this method, the fracture resistance of direct restorative materials, resin‐based inlay/onlays and luting cements can be evaluated.
