Crowns were designed with\/without occlusal vent holes and produced from monolithic zirconia blocks by the CAD\u2010CAM technique. The two crown types were divided into two groups and cemented with resin and zinc\u2010polycarboxylate cement under 5 kg weight. A universal testing machine applied compressive forces to the crowns until fracture.
