Abstract: Method for extracting an implant installed in a bone, which comprises the application of a torque on an extraction tool in order to thread it in the interior of the implant until the implant-bone connection is broken, with the specific feature that the torque is applied in phases. In each phase a torque that is increasingly greater than in the previous phase is applied and the application of torque is then eased. This method brings about a gradual and controlled deformation of the head of the implant, with the result that the extraction tool is inserted more deeply into the implant. As a result, higher breakage torques may be applied without damage being caused to the extraction tool.
