ABSTRACT


Objective: The
purpose of this study was to assess and contrast the shear bond strength of a
veneer composite resin bonded to cobalt-chromium (CoCr) dental alloys produced
by different techniques.


Material-Method:
Ninety cylindrical specimens (10mm in
diameter, 8mm in height) made of CoCr dental alloys were prepared by casting
(C), milling (M), LaserCUSING with and without annealing (CL+, CL), and direct
metal laser sintering (DMLS) with and without annealing (EL+, EL). Veneer
composite cylinders (5mm in diameter, 3mm in height) were built on metal
specimens using a silicone jig. After storage in water for 24 hours, the
specimens were assessed for bond strength with a shear force test at a
crosshead speed of 0.5 mm/min. The shear bond strengths (SBSs) were
statistically analyzed using the Kolmogorow-Smirnow test and Tukey-HSD multiple
comparison test (α=.05).


Results: When
the SBS values of the groups were compared, significant differences were found
among the groups (P<.05). While statistically significant differences were
found between the CL+ group (9.36∓2.62)
and the M group (13.34∓2.53)
(P .05).
The debonded surfaces of the specimens exhibited mostly mixed failure types.


Conclusions: The
CoCr alloy fabrication technique has an effect on the SBSs between the veneer
composite resin and the metal used. LaserCUSING casting, a new technology,
seems to have the lowest metal-resin bond strength among all the techniques
tested.
