简要总结
The objective of this study is to assess the survival rate and the biological and technical outcomes of onlays and single crowns made out of different restorative materials on vital and non-vital teeth. The onlays are made either out of a lithium-disilicate glass ceramic (E.max CAD, Ivoclar Vivadent), hybrid ceramic (VITA ENAMIC, VITA Zahnfabrik) or out of a lithium aluminosilicate glass ceramic reinforced with lithium disilicate (N!ce, Straumann). The crowns are made either out of lithium aluminosilicate glass ceramic reinforced with lithium disilicate (N!ce, Straumann), hybrid ceramic (VITA ENAMIC, VITA Zahnfabrik) or lithium-disilicate glass ceramic (E.max CAD, Ivoclar Vivadent).
