Clinical Effect of Feldspar Glass Ceramics and Lithium Disilicate Reinforced Glass Ceramics
The clinical effect of feldspar ceramics and lithium disilicate reinforced glass ceramics was studied. 57 affected teeth with complete root canal treatment and computer aided design/computer aided manufacturing (CAD/CAM) endocrown restoration were reviewed 24‐36 months aftercompletion of the restoration. These dimensions including anatomical morphology,
