Comparative Evaluation of Different Occlusal Surface Designs of Artificial Crown
In Brief
A clinical study evaluating FGP and AVR for Dental Crown and Prosthesis. Completed, enrolled 12 participants across 1 site.
Detailed Summary
The purpose of this study is to compare among different designs of the occlusal surface of artificial crowns, trying to determine a guidance of fabricating artificial crowns with better mimesis of the original tooth crown in terms of morphology.
Study Details
Timeline
Interventions
To execute FGP technique, the occlusal surface of the interim should be back cut to leave at least 1mm occlusal space. Then apply the recording resin. Ask the subjects to close the mouth to maximum intercuspal position then perform right lateral, left lateral and protrusive movements in succession ending in maximum intercuspation position. Excessive resin then should be trimmed off and Bausch articulating paper would be used to mark the intercuspal contacts. Zinc oxide is then applied to check eccentric occlusion, trimmed off resin if there're interferences. Then the interim would be used as a copy to design the occlusal surface of the crown. (CAD/CAM)
the crowns in this group would be designed by setting virtual articulator to average mode (CAD/CAM)
