Statement of problem:
Screw loosening has been attributed
to many factors including decrease in optimum preload
value.
Material and method:
Eighteen implant supported cement
retained framework were fabricated from base metal alloy
using conventional casting technique on eighteen straight
abutments (Implantium). Abutments were fastened by
titanium screws to implant body (Implantium) by 30 Ncm 5
minutes later. Detorque by 30 Ncm torque and re-tightened
to 30 Ncm 5 minutes later. Detorque values were measured
10 minutes later. Spacemens were divided to three group’s
randomly. In group B and S after separating abutments from
implants, abutment-implant interface were contaminated
with blood and saliva respectively and in control group (C)
no contamination was created. All abutment screws were
tightened to 30 Ncm for third time. After cyclic loading test
(one million cycles) detorque values for three groups were
measured. Data were analyzed by one way ANOVA test.
Result:
there was significantly decrease in detorque value
before and after cyclic loading for all groups (P<0.001)but
the differences between three groups after cyclic loading
were not significant (P=0.221).
Conclusion:
Within the limitation of this study the difference
of preload values and preload loose in clean, blood and
saliva contaminated implant-abutment interfaces were not
significant
