A comparison of the tensile strength of four prosthodontic adhesives.
OBJECTIVE
This study compared the in vitro tensile bond strength of four prosthodontic adhesives to sandblasted base-metal alloy.


METHODS
Alloy cylinders were bonded end-to-end with the various adhesives, thermocycled, stored for 28 days, and subjected to a tensile load.


RESULTS
Mean tensile bond strengths obtained were: Panvia = 42.3 MPa, Metabond = 31.1 MPa, All-Bond = 28.06 MPa, and F21 = 18.5 MPa. Statistical analysis showed significant differences (P < .05) in mean bond strengths between the adhesive systems.


CONCLUSIONS
Under the conditions of this study, the Panavia system showed the strongest mean tensile bond strengths.
