Problems with present methods used to check if there has been sufficient occlusal reduction to accommodate a full coverage crown include disregarding optical scanning, limited vision and difficulties in identifying those areas of the preparation that require further reduction. This paper describes a modification of the commonly used wax wafer technique. After initial reduction, a functionally generated wax wafer is formed. Areas that require further preparation are identified by measuring the residual thickness of the wax with a graduated periodontal probe, and those thinned areas are marked on the occlusal table with a high speed diamond bur. Another less familiar method is illustrated. This shows a photograph of a plastic loop mounted on a handle (occlusal reduction ring) that is pulled over the preparation when the patient is guided into different excursions. Snagging of the loop indicates the need for occlusal refinement.
