title: The axiopulpal line angle and its relationship to fracture resistance of three dental alloy systems.
abstract: Under the circumstances of this experiment, the following conclusions may be drawn: The fine-cut alloy system (Velvalloy) has a higher resistance to fracture than the spherical alloy system (Spheraloy) or the dispersed-phase alloy system (Dispersalloy). The class II preparation for posterior teeth should contain a round axiopulpal line angle. Further studies to evaluate other modifications of preparation design are justified.
