To evaluate the influence of cementation on fracture load of anterior crowns made of CAD/CAM-resin-blocks (ART), leucite-reinforced glass-ceramics (LRG), lithium disilicate ceramics (LIT), veneered zirconia (ZRO) and veneered alloy (DEG). Each crown group (n=15/subgroup) was cemented on the metal abutment as follows: i. using glass ionomer, ii. using self-adhesive resin cement, and iii. not cemented. Crowns were tested and analyzed with 2-way and 1-way ANOVA (Scheffé test), and Weibull statistics (p<0.05). Within LRG, self-adhesive cemented subgroup showed higher fracture load compared to other groups (p<0.001). Among DEG, lower results were measured for non-cemented crowns than for cemented (p<0.001). For ART, LIT and ZRO no influence of cementation was observed. For fracture load test methodology, metal ceramic crowns should be generally cemented. Glass-ceramic crowns should be cemented using adhesive cement. Cementation and cement type did not have an influence on the fracture load results for resin, zirconia or lithium disilicate crowns.
