Retention Strength after Compressive Cyclic Loading of Five Luting Agents Used in Implant-Supported Prostheses

Table 2

Mean tensile retention strength of tested cement types before and after cyclic compressive loading.

Resin composite; (Multilink Implant)	443.15; (69.41)	352.02; (76.05)	0.055	20.56
Glass ionomer; (Fuji I Capsule)	100.41; (33.55)	50.35; (30.37)	0.007	49.86
Compomer; (Stay Bond)	161.13; (53.34)	75.12; (72.63)	0.005	53.38
Resin urethane-based; (Premier Implant Cement)	174.76; (45.59)	71.25; (73.86)	0.005	59.23

Values of retention in Newton; . Standard deviation in brackets. The Tukey test: statistically significant differences with respect to glass ionomer cement; statistically significant differences with respect to the other four cement types; statistically significant differences with respect to glass ionomer and resin urethane-based cement types.
