| description | Objectives: To evaluate the effects of the abutment material and the connection type on the
implant-abutment connection rigidity.
Methods: The study evaluated eighteen implants with three different types of connections:
external-hexagon, tri-channel, and conical connection. Half of the implants were connected
to titanium abutments, and the other half to zirconia abutments, forming six study groups
(n=3). The implants were submitted to 1,200,000 load cycles with a force amplitude of 90 N.
During load application, the implant-abutment connection rigidity was determined in each
cycle. The values obtained were analyzed with the two-way ANOVA test according to the
abutment and connection types.
Results: Rigidity tended to increase during loading cycles. The abutment material did not
influence rigidity (p=0.883). The external-hexagon connection presented lower rigidity than
the internal connections, with statistically significant differences (p=0.013).
Conclusions: The abutment material does not influence the implant-abutment connection’s
rigidity. The external-hexagon connection proved to be less rigid and stable than the internal connections. |
