DETAILED DESCRIPTION OF THE INVENTION

[0024] The following description includes the preferred best mode of one embodiment of the present invention. It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting. While the invention is susceptible to various modifications and alternative constructions, it should be understood, that there is no intention to limit the invention to the specific form disclosed, but, on the contrary, the invention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the invention as defined in the claims.

[0025] As used herein, the singular forms “a”, “an” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0026] In reference of FIG. 1, the present invention relates to a method of producing an orthodontic transpalatal arch having multiproperties. It includes the steps of: [0027] taking a sterile electrical wire (01) wherein the electrical wire (01) is pushed to follow the palatal contour, opposite to the area of the upper first right and left side molars with the help of a band pusher to record all texture and contour of the palatal area from upper left first molar to upper right first molar, [0028] arranging a twistflex (02) inside a plastic tube (04) piece, [0029] fixing the plastic tube (04) with twistflex (02) to the wire in a similar shape of the wire recorded for the palatal area by a plurality of hair clamps (05), [0030] pouring a resin material inside the plastic tube (04) based on the required properties of the transpalatal arch. [0031] setting the resin material along with the twistflex (02), and [0032] cutting the plastic tube (04) to release the set resin material with the twistflex (02).

[0033] In a preferable example, the size of the sterile electrical wire (01) is 2*1.5 (semeins Co, Germany) and length of the wire is about 12 cm as shown in FIG. 2. FIG. 2 represents an electrical wire (01) which has been pushed to follow the palatal contour of the patient's mouth, opposite to the area of the upper first right and left side molars with the help of a band pusher to record all texture and contour of the palatal area from upper left first molar to upper right first molar.

[0034] FIG. 3 represents the plastic tube (04) which is fixed to the electrical wire (01) by the hair clamps (05). The plastic tube (04) used is for example is an intravenous giving device (I.V. giving fluid device), preferably the length is about 12 cm. The plastic tube (04) is used to adhere or fix to the wire by using the hair clamps (05) (hair grips or bobby pins). The plastic tube (04) is fixed to the wire as such that it follows all the curvature of the wire. Therefore, the tube acts as a mold for the later step of preparing the TPA.

[0035] FIG. 4 represents a step of the method in which the plastic tube (04) is filled with the resin cement through a tube of the resin cement, orthodontic braided wire of steel (twistflex (02)), was inserted inside the plastic tube (04) as reinforcement for the TPA according to the required properties of the TPA.

[0036] The properties of the TPA in the present invention depend on the properties of the resin which is injected inside the tube, so the material engineering plays a role in determination of the properties of the TPA. For example one of the suitable materials is fibre reinforced composite to provide more rigid TPA. Additionally, hard stain less steel and/or orthodontic braided wire of steel—twistflex (02) gauge preferably of 0.032 inch may be added inside the tube to increase the rigidity. In other case, addition of plasticizer to fiber reinforced resin is used for maxillary expansion to provide flexible TPA. In other case normal light cure of resin is done or duel cure resin cement arranged inside the tube in addition to one or two of braided wire of steel—twistflex (02).

[0037] Now, the resin material or other material is set inside the plastic tube (04) through a light cure device (08), usually the resin is light or duel cure. FIG. 5 represents a step to set the resin by curing light providing through a light cure device (08). The light passes through the transparent material of the tube to the resin inside, while the plastic tube (04) has been holded through the hair clamps (05) or bobby pins with the electrical wire. There is no need of light cure in case of the chemical cure of the resin.

[0038] FIG. 6 represents a step of cutting the plastic tube (04) to separate the plastic tube (04) from the rigid and set resin cement through a surgical blade (06). The longitudinal cut has been done in plastic tube (04) to release the set resin from inside the tube which provides the TPA.

[0039] FIG. 7 represents the plastic cut as shown in FIG. 6 at left side and a TPA produced through the present method which is ready for cementation. The set resin core once peeled acts as the TPA that contains all the curvature details of the palatal area, and is ready for cementation inside patient mouth.

[0040] TPA inside the patient mouth is fixed by the help of acid etch technique. FIG. 8 represents the TPA after cementation, finishing and polishing inside the patient's mouth TPA prepared according to the present invention is without bands and thus it can easily remove any time without interfering with arch wire in the fixed appliance.

[0041] This saves time and effort. Further, it solves the problem which occurs through the conventional TPA with bands such as periodontal problem and bacteremia, patient discomfort, white spot lesions that might develop underneath the bands and residual space after band removal.

[0042] Although the invention has been described with reference to specific embodiments, this description is not meant to be construed in a limiting sense. Various modifications of the disclosed embodiments, as well as alternate embodiments of the invention, will become apparent to persons skilled in the art upon reference to the description of the invention. It is therefore contemplated that such modifications can be made without departing from the spirit or scope of the present invention as defined.
