RESUMO
Aim:
To evaluate the occurrence of microstrain around morse taper implants in straight configuration under axial load in a cast monoblock framework.Methods:
Three implants were inserted in a polyurethane block and microunit abutments were installed on the implants with 20 Ncm torque. Plastic and machined copings were adapted on the preset waxing to fabricate the framework (n=5). Four strain gauges were attached on the upper surface of the block and then each framework was tightened on the abutments and a vertical load of 30 kg was applied to five points of the framework.Results:
The data obtained in the strain gauge analysis were subjected to twoway ANOVA and Tukeys test (=0.05). There was statistically significant difference (p=0.0222) for the factor application point and the mean microstrain values were application point B 402,04µ, point A 401.21µ, point E 390.44µ, point D 341.76µand point C 309.19 µ.Conclusions:
There was no microstrain difference between plastic and machined copings during axial loading. Difference in the application point was observed, but remained within bone physiological limits.
