Support and guide for dental drill - comprises arm articulated to fixed support and provided with device maintaining drill turbine orthogonal to working plane

摘要

The device comprises a movable arm (3) which can be attached to a fixed support (4) and provided with an attachment (88) for a tail (20) of the drill (2). The arm (3) includes a restraint (40) operable to maintain the axis of rotation (A) of the turbine orthogonal to a predetermined working plane (pi). The arm (3) can include a first portion (10) which can be attached to the fixed support (4), a terminal; portion (13) provided with the attachment (88) for the drill, and an intermediate portion (11). The first portion (10) and the end portion (13) of the arm (3) may be articulated to the intermediate portion (11) by means of first and second pivot couplings (12, 14) operable to permit relative rotation about respective first axes (B, B') parallel to one another and orthogonal to the working plane.
