  • Process for making an expansion screw for orthodontics and screw thus made
    Patent number: 6644967
    Abstract: The present invention refers to a process for making an expansion screw and a screw thus made; the expansion screw (100, 100′) has two bodies (1, 2) that can be spaced apart by acting on the driving portion (6) of a double screw (3) housed within threaded central bores (30) provided in the two bodies (1, 2); each of the bodies (1, 2) has at least one bore (5, 50) parallel to the threaded bore; also provided is at least a hollow cylindrical guide (9) housed within a corresponding pair of parallel bores (5, 50) disposed on the two bodies (1, 2) in facing relationship; inserted in each guide (9) is a pin (4) for sliding therein; each guide (9) is fixed to one of the bodies, while the relevant pin (4) held therein is fixed to the other body, and the sliding of the pin (4) relative to the guide (9) takes place with friction owing to the force exerted upon assembly.
