Researchers used mechanical testing and computer modelling to assess how the location of proximal box tooth preparation affects the fracture resistance of single-retainer resin-bonded fixed prostheses made from zirconia, finding that incisal placement of the proximal box improved predicted fracture resistance compared with other locations.
