Abstract
The present invention relates to a ligating device (1) for arch wires or orthodontic wires, having a bondable base (2), for coupling to a tooth, and a main body (3), where the main body (3) has a slot (4), suitable for receiving a metal arch wire (5). The slot (4) has its entrance on one of its gingival or occlusal sides. The invention relates also to a method for the application of an arch wire or an orthodontic wire (5), by insertion of the arch wire or orthodontic wire (5) in a plurality of ligating devices (1) for arch wires or orthodontic wires, along a gingival-occlusal, or occlusal-gingival direction of insertion.
Claims11
A ligating device (1) for arch wires or orthodontic wires, comprising a bondable base (2), for coupling to the tooth, and a main body (3), said main body having a slot (4), suitable for receiving a metal arch wire or orthodontic wire (5), said device (1) being characterized in that said slot (4) has an entrance on a gingival or occlusal side where said slot (4) is made accessible or closable by a clip (6;
- 6′), said body (3) having, along a vestibular-lingual axis, an opening (10) said opening (10) being accessible from, and being suitable for receiving said clip (6;
- 6′), from, the vestibular side or from outside the tooth on which the ligating device is installed and in that said clip (6;
- 6′) opens and closes said slot (4) sliding along said vestibular-lingual axis wherein said clip (6;
- 6′) is substantially “U”-shaped, having one first arm (11) which faces and closes or opens said entrance of said slot (4) and a second arm (12) opposite to said slot (4) with respect to the first arm (11), said first arm (11) having flaps (14) which prevent said clip from passing through grooves (17) in a vestibular arm (9) on said main body (3) said first arm (11) having a second slit (13) and said second arm (12) having a first slit (15;15′).
A ligating device (1) for arch wires or orthodontic wires, comprising a bondable base (2), for coupling to the tooth, and a main body (3), said main body having a slot (4), suitable for receiving a metal arch wire or orthodontic wire (5), said device (1) being characterized in that said slot (4) has an entrance on a gingival or occlusal side where said slot (4) is made accessible or closable by a clip (6;
- 6′), said body (3) having on the plane parallel to the tooth on which the device installed, an opening (10), suitable for receiving said clip (6;
- 6′), wherein said body (3) has a substantially “U”-shaped section, defined on both sides of said slot (4) by a first lingual arm (8) and a second vestibular arm (9) and in that said clip (6;
- 6′) opens and closes said slot (4) sliding along a vestibular-lingual axis wherein said clip (6;
- 6′) is substantially “U”-shaped, having one first arm (11) which faces and closes or opens said entrance of said slot (4) and a second arm (12) opposite to said first arm (11), said first arm (11) having flaps (14) which prevent said clip from passing through grooves (17) of said second vestibular arm (9), said first arm having a second slit (13) and said second arm having a first slit (15;15′) wherein said device is adapted to allow the use of an external tool (20), equipped with a handle (22) and a tip (21), suitable for coupling itself with a first slit (13), in order to exert on a clip (6;
- 6′) a force in the lingual-vestibular direction, where said force is sufficient to make said slot (4) move from a closed position to an open position.
