A new approach for atraumatic implant explantation and immediate implant installation

Objective. This study reports a new approach for implant extraction in a convenient, fast, and atraumatic way and allowing a new implant placement at same surgical time. Study Design. The Biotechnology Institute extraction kit consists of a wrench that allows a 200 N-cm countertorque force, an internal connection extractor, an extractor for external connection, and a set of ratchet handle extension pieces. In this study, a total of 91 implants installed in 42 patients were explanted. Results. Extraction torques ranged from 80 to 200 N-cm. In those cases in which implant removal torques exceeded 200 N-cm, a 2-3-mm depth incision was done using a set of atraumatic trephines to avoid too high countertorque forces. Conclusions. The possibility of extracting osseointegrated implants opens new doors in oral implantology. The extraction kit allows dentists to re-treat cases and improve the final results, achieving the best outcomes for patients. (Oral Surg Oral Med Oral Pathol Oral Radiol 2012;113:e19-e25)
