Background : Performance of the counter-torque technique in the explantation of nonmobile dental implants
Although presenting high and acceptable survival rates [1, 2], dental implants fail as a consequence of infection (periimplantitis), excessive biomechanical stress, or improper positioning. Different techniques have been described to remove a failed dental implant that include block resection, buccal bone osteotomy, trephine osteotomy, and piezosurgery [3, 4]. The application of counter-torque to break the implant-bone interface has been proposed as a safe, efficient, and atraumatic strategy to remove nonmobile implants [4]. As a minimally invasive technique, Solderer et al. have recommended the counter-torque technique as the first option for the removal of failed nonmobile dental implants [5]. Nevertheless, there is a need of studies with a larger sample size to confirm the efficacy and safety profile of this strategy. This study aims to assess the performance of the counter-torque strategy for the removal of a large number of nonmobile dental implants.
