Fatigue behavior of resin-modified monolithic CAD–CAM RNC crowns and endocrowns

Fatigue behavior of resin-modified monolithic CAD–CAM RNC crowns and endocrowns

Highlights • No significant differences were found in terms of fatigue resistance between crowns and endocrowns. • Monolithic crowns performed better than the buccal-occlusal veneered counterparts. • Endocrowns fractured predominantly with a mesio-distal wedge-opening fracture (82%). • Partial cusp...

Zusammenfassung:Highlights • No significant differences were found in terms of fatigue resistance between crowns and endocrowns. • Monolithic crowns performed better than the buccal-occlusal veneered counterparts. • Endocrowns fractured predominantly with a mesio-distal wedge-opening fracture (82%). • Partial cusp fractures were observed above all in crowns (70%).
