Abstract
Background
The
application of the counter-torque technique has been proposed as a
conservative and atraumatic alternative for the explantation of
nonmobile dental implants. The objective of this report is to assess the
performance of this technique in a large number of patients.
Results
Three
hundred and fifty-five patients were treated for the explantation of
749 nonmobile dental implants. The explantations were performed by the
application of counter-torque to break the bone-implant interface.
Successful implant explantation was achieved in 98.4% of the implants.
The frequency of complications was 1.3%, most commonly related to the
appearance of fissure lines at the implant neck.
Conclusions
The counter-torque technique has a high success rate but is not exempt from complications, although at a very low rate.
