摘要:
The invention relates to a method for producing a bent orthodontic arch or a bent retaining arch for orthodontic treatment, comprising the bending of portions of a metal wire. The invention is characterised in that it comprises the use of an apparatus of the type intended for the production of springs, comprising bending tools and means allowing the continuous movement of the wire to be bent. The invention also relates to the device used to perform the aforementioned method, to the resulting orthodontic arch or retaining arch and to an orthodontic appliance comprising same.

An orthodontic assembly includes a self-ligating attachment having a groove for receiving an orthodontic arch. An elastic clip can be reversibly moved between an open position and a closed position sealing the groove. A base including an external surface and an occlusal surface, said external surface of the base supporting the attachment and said occlusal surface of the base being intended to rest on one of the patient's teeth. The aforementioned clip can be moved in an at least partially rotational manner between the open position and the closed position. Moreover, the area of the above-mentioned base that supports the attachment comprises a depression at least partially in the form of a cup and the clip is inserted into the depression when in the closed position.

An assembly of a self-ligating bracket intended to be part of an orthodontic apparatus. The bracket having in the longitudinal direction thereof an outer face and an occlusal face and being provided on the outer face thereof with a groove for holding an orthodontic arch wire. An elastic clip that can be moved in a reversible manner between an open position, leaving a free passage for the insertion of the arch wire into the groove or the extraction of the arch wire from the groove, and a closed position closing off the groove. The clip being moveable between said positions by a rotational movement, without the clip sliding in translation.
摘要:
A method of producing a customized orthodontic appliance for treating a patient where the appliance includes at least one orthodontic arch and a plurality of elements each including a bracket provided with at least one slot in which said orthodontic arch can be inserted. Each bracket being configured to be placed on a base intended to be placed on a posterior face of a tooth. The method includes individual numerical design of said bases after forming a model representing the dental arch and the faces of the teeth to which said bases are to be fixed in the corrected position. At least some of said bases are numerically designed and manufactured using rapid prototyping. A mass-produced bracket is fixed to each of said bases. An orthodontic arch is numerically designed and manufactured so that it follows the curvature of the dental arch in the corrected position.

A self-ligating attachment intended to form part of an orthodontic appliance, the external surface of said attachment being provided with a groove for receiving an orthodontic arch. A elastic clip that can be reversibly moved between an open position forming an open passage allowing the insertion of the arch into the groove and a closed position sealing the groove. A base including an external surface that supports the attachment and an occlusal surface which is intended to rest on one of the patient's teeth, so as to hug the surface of the tooth. In addition, the base comprises a support for the attachment and said base assists in the guiding of the clip, cooperating with the attachment, as the clip moves between the open and closed positions.

The invention relates to a customised jig for an orthodontic appliance, to an assembly formed by the jig, a base and a bracket, and to the associated design methods. The customised jig is used to install a bracket-bearing base on a tooth, said base forming part of an orthodontic appliance. The invention is characterised in that: the jig is a cap that covers the tooth, covering the free edge thereof and at least portions of the front and rear surfaces of same; and the shape of the jig is such that it matches that of the base in at least one portion of at least one of the edges thereof. The invention also relates to an assembly formed by a customised base bearing a bracket and a customised jig of the type mentioned above, and to methods for designing one such jig.
