Set of motor-driven instruments to aid the fixing of dental implants that combines drills (1, 2) and motor-driven osteotomes (4A, 4B, 4C, 4D) of progressive diameters. These have a threaded conical section (9), followed by a threaded cylindrical section (8) and another area (7) to fit the connectors (14, 17) to the surgical motor or a manual extractor. |
