The article focuses on designing occlusal surfaces for zero interference (Z I ). Patient and dentist can experience stress-free and pleasant appointment for try-in of symmetrical crown and bridge restoration when occlusal surfaces are designed for Z I. Its ideal design in the three-unit bridge has opposing tooth contacts located on cusp tips and opposing central grooves. Care should be considered to keep the Z I cusp tip moldspacer at minimum thickness. There should be a harmony in degree of cusp steepness between the restoration and the patient's natural dentition.
