A fixing device (1: 20) for orthodontic devices which includes a screw (2; 40) complete with an operating head (3; 42) with longitudinal slots (4; 45) for the insertion of orthodontic devices and a threaded shank (5) designed to be screwed inside the patient's oral cavity; apparatus for fixing orthodontic devices contained inside the operating head (3; 42). The fixing apparatus includes a shaped body (6) engaging inside a recess (7, 47) in the operating head (3; 42) and revolvable inside the recess (7; 47). The shaped body (6) has a through opening (8) for the insertion of the orthodontic device and opposing apparatus that anchor the orthodontic device to the operating head (3; 42) when the shaped body (6) is rotated inside the recess (7; 47) after the orthodontic device has been inserted in the through opening (8) and in the longitudinal slots (4; 45).

1. An orthodontic fixing device, comprising: a screw, said screw including an operating head with a longitudinal slot for receiving at least one orthodontic device, said screw also including a threaded shaft suitable for screwing into an oral cavity, said operating head including a recess; anda shaped body, coupled inside a said recess and rotatable in said recess, said shaped body including a through hole for the insertion of one of said at least one orthodontic device, said shaped body also including a shaped slot for retaining said one of said at least one orthodontic device inside said operating head when said shaped body is rotated inside said recess after inserting said one of said at least one orthodontic device in said through hole and in said longitudinal slot, said shaped slot including two opposing surfaces;wherein said shaped slot is located inside said shaped body and is in communication with said at least one through hole, said shaped slot lying on a plane substantially orthogonal to the longitudinal axis of said screw; andwherein one of said two opposing surfaces is inclined relative to the other surface of the two opposing surfaces, defining between said two opposing surfaces a profile for said shaped slot that converges towards a bottom of said slot, said bottom being defined between said two opposing surfaces, said two opposing surfaces being capable of retaining said one of said at least one orthodontic device inside said operating head by each contacting said at least one orthodontic device when said shaped body is rotated inside said recess. 2. The fixing device according to claim 1, wherein a lateral surface of said shaped body has one or more projections designed to engage inside corresponding ring-shaped cavities prepared located on an inner surface of said recess for containing said shaped body. 3. The fixing device according to claim 2, wherein said one or more projections consist of a single ring-shaped projection. 4. The fixing device according to claim 1, wherein said operating head includes a base for attaching the head to the shaft of said screw. 5. The fixing device according to claim 4, wherein, said fixing device includes a narrowed section in said base of the head. 6. The fixing device according to claim 5, wherein said fixing device includes at least one through hole disposed in said narrowed section. 7. The fixing device according to claim 1, wherein said at least one orthodontic device is an orthodontic wire. 8. The fixing device according to claim 1, wherein said at least one orthodontic device is a part of one of the group consisting of a grid, a flask, and a plate. 9. The fixing device according to claim 3, wherein said fixing device has at least one ring-shaped cavity disposed on an external surface of said head of said screw for containing orthodontic wires. 10. The fixing device according to claim 1, wherein said two opposing surfaces are positioned to clamp said at least one orthodontic device. 11. A multi-component orthodontic fixing device comprising: a screw having an operating head and having a threaded shaft that extends longitudinally;the operating head including a recess;a shaped body rotatably mountable the recess, the shaped body including first and second slots;the first slot extending across and through the operating head, and downward into the shaped body toward the threaded shaft;the second slot being generally transverse to and intersecting the first slot, the second slot including first and second opposed surfaces;wherein the first and second opposed surfaces are spaced apart but inclined toward each other;wherein the shaped body is rotatable between first and second positions within the recess of the operating head such that at least one orthodontic device can be inserted into the first slot when the shaped body is in the first position;wherein the first and second opposed surfaces each is configured to engage the at least one orthodontic device in the second slot when the shaped body is rotated to said second position.
