Description

Technical Field

[0001] The utility model relates to the technical field of teeth, in particular to an orthodontic appliance suitable for maxillary front teeth. Background Art

[0002] The eruption of maxillary incisors has an inducing effect on the development of the maxillary bones. The central incisor is located in the premaxilla. After impaction, the development of the maxilla is hindered. Due to long-term growth disorders, the development of the upper and lower jaws shows a tendency to skeletal crossbite. The upper and lower jaw anterior teeth show compensatory phenomena, with the upper teeth labially inclined and the lower teeth lingually inclined, showing a concave shape. After the incisor is impacted, the development of the premaxilla is inhibited. Impacted teeth are a common type of dental deformity in orthodontic clinics, with an incidence rate of about 1% to 2% in the population. Epidemiological studies have shown that the prevalence of impacted teeth in Chinese people is approximately 7.39% to 8.56%, among which the prevalence of maxillary canines is as high as 3.31%.

[0003] In clinical practice, the devices commonly used to pull impacted maxillary anterior teeth are removable appliances and fixed appliances. Common methods include Nance arch, removable appliances with finger springs or implant anchorage. When the above appliances are used in conjunction with elastic wires or rubber chains to pull the labial anterior teeth, they will compress the adjacent mucosa, causing abrasion marks on the mucosa. If too much force is applied, it may also cause mucosal hyperplasia to wrap around the elastic wires or rubber chains, resulting in mucosal scars.

[0004] To this end, we design an orthodontic appliance suitable for maxillary anterior teeth to provide another technical solution to the above technical problem. Utility Model Content

[0005] Based on this, it is necessary to provide an orthodontic appliance suitable for maxillary anterior teeth to solve the technical problems raised in the background technology.

[0024] Reference Figure 1-Figure 3 , an orthodontic appliance suitable for maxillary anterior teeth, comprising an impacted tooth 1, a mesial adjacent tooth 2 and two cast band rings 8, wherein the impacted tooth 1 is located at the inner side of the bottom of the mesial adjacent tooth 2, and the cast band rings 8 are located at two ends of one side of the impacted tooth 1, and then the two cast band rings 8 are respectively arranged on the maxillary bilateral posterior teeth, and a Nance palatal support 6 is welded between the two cast band rings 8, so as to enhance the support of the posterior teeth, prevent the molars from twisting during unilateral traction, and maintain the width between the molars, and the ends of the two cast band rings 8 that are away from each other are welded with a double-tube buccal tube 5, so that the upper tube of the double-tube buccal tube 5 can be conveniently used for further aligning the teeth in the later stage, and a loop 4 is welded at the bottom of the double-tube buccal tube 5, so that the end of the loop 4 is inserted into the lower tube of the double-tube buccal tube 5 and welded;

[0025] A bending piece 7 is fixed on the inner side of the Nance palatal support 6, and the shape of the bending piece 7 is Ω-shaped. The Nance palatal support 6 is bent using 0.9mm stainless steel wire, so that the self-curing resin base wraps the "Ω"-shaped bending piece 7 and is close to the maxillary palatal mucosa, and the remaining part of the steel wire is about 2mm away from the palatal vault mucosa. A single-curved lip bow 3 is fixed on one side of the Nance palatal support 6, and the single-curved lip bow 3 is bent using 0.9mm stainless steel wire, so that the tail end of the single-curved lip bow 3 is embedded in the Nance support self-curving resin base, located on the labial side of the traction tooth, about 2mm away from the mucosa, and connected to the traction tooth by an elastic line or rubber chain and other devices, so that the traction tooth moves away from the adjacent tooth.

[0026] The loop 4 is located at one end of the mesial adjacent tooth 2, so that the loop 4 can be set at a position far from the mesial adjacent tooth 2. The loop 4 is bent with 0.9 mm stainless steel wire, one end of the loop 4 is welded to the single-curved labial bow 3, and the other end of the loop 4 is welded to the casting band ring 8, so that the loop position of the loop 4 is determined according to the position of the impacted tooth 1, and can be set between the first and second premolars, or in the mesial of the second molar. After the impacted tooth 1 is completely exposed from the labial mucosa, it is connected to a device such as an elastic line or a rubber chain to pull the impacted tooth 1 downward and backward until it is basically in place. The stainless steel wire needs to be 2 mm away from the mucosa and tooth surface to facilitate oral cleaning.

[0027] When using the braces provided by the present embodiment, first check whether the maxillary first molar has caries, tartar and occlusion, then remove the soft plaque and food residues on the tooth surface, then place glass ionomer cement on the inner side of the band ring to bond the braces, push the band ring into place with the thumb, check whether the Nance palatal support 6 is in close contact with the maxillary palatal mucosa, and then after the braces are completely in place, let the patient bite the cotton roll for 10 minutes to wait for the glass ionomer adhesive to solidify, and then wear the braces, so that the maxillary anterior teeth that are impacted on the labial side and close to the adjacent teeth can be pulled when used; at the same time, the positioning single-curved lip bow 3 is used to first pull the impacted tooth 1 toward the labial side, directly pull and apply force to avoid compressing the oral mucosa, and weld and connect it to the single-curved lip bow 3 through the loop 4, the loop is located at the maxillary premolar, and after the impacted tooth 1 is basically exposed to the labial mucosa, the impacted tooth 1 can continue to be pulled backward and downward until it is basically pulled into place, and because of its simple structure, it also helps oral cleaning.
