According to this method, one makes a three-dimensional solid reproduction (12) of the anatomical zone of implantation and, from this reproduction, a drill assistance device (30) comprising a rigid base (35) provided with at least one drill guide (34, 38). According to the invention,—the three-dimensional solid reproduction (12) consists of a reproduction of an internal and peripheral portion of said bone structure, exempt, at least in the vicinity of each implant hole, from the surrounding non-osseous tissues and mucosa,—said rigid base (35) having at least one surface, called contact surface, adapted to be able to bear in contact with an external surface portion of the three-dimensional solid reproduction (12), and therefore also later in contact with a peripheral surface portion of said bone structure.
