Regardless of the fabrication workflow occlusal adjustments seem to be inevitable during delivery of indirect fabrication of the restoration. This has been attributed to snowballing of discrepancies due to multiple procedures for information transfer between the clinician and the laboratory. Current digital workflows minimize these discrepancies due to digital acquisition technology which eliminates drawbacks from physical materials which would alter the dimensions and morphology of the final restoration. Utilizing 3D face scanning technology is by far the least invasive and the least time consuming of available virtual facebow techniques and thus it's utilization could offer the benefit of saving time during occlusal adjustment and enhanced strength of the restoration by not subjecting it to the heat generation and subsequent crack initiation which occurs during occlusal adjustment. This study aims to compare the effect of a face scan to alignment of the maxillary cast on the volume and time of occlusal adjustment compared to conventional articulator digitization to align the maxillary cast.

Clinical Occlusal Adjustment Time
Timeframe: Immediately after verification of restoration acceptability but prior to occlusal adjustment. Time will be measured until occlusal contacts of the crown have been harmonized during the delivery clinical visit.
