Influence of occlusal thickness on the fracture resistance of chairside milled lithium disilicate posterior full‐coverage single‐unit prostheses containing virgilite: A comparative in vitro study

This is the authors' abstract. We don't add key points for this paper.

To evaluate the fracture resistance of chairside computer-aided design and computer-aided manufacturing (CAD-CAM) lithium disilicate mandibular posterior crowns with virgilite of different occlusal thicknesses and compare them to traditional lithium disilicate crowns.
