Summary

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.

Conditions

  • Dental Occlusion
  • Crowns

Interventions

PROCEDURE

Digitized Mounted Articulator Scan

Conventional articulator facebow mounting will be digitized using extraoral digital 3d scanner and used to position the maxillary cast on the virtual articulator. This positioning will be utilized during design of the occlusal surface of the restoration.

PROCEDURE

Average Positioning on Virtual Bonwill Triangle

Virtual Bonwill triangle will be used to position the maxillary cast on the virtual articulator. This positioning will be utilized during design of the occlusal surface of the restoration.

PROCEDURE

Digital Face Scan

Digital face scan will be used to position the maxillary cast on the virtual articulator. This positioning will be utilized during design of the occlusal surface of the restoration.
