Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a combined flat-guided Nance support and correction device. Background Art

[0002] The flat guide appliance is the most commonly used simple functional appliance in clinical practice. It is usually worn on the upper jaw and is usually used for deep overbite during the deciduous dentition, replacement dentition, and permanent dentition periods. It is used in conjunction with a fixed appliance to open the bite and flatten the dental arch.

[0003] The shape and structural structure of existing similar products are mainly composed of a zero-space hook made of 4 steel wires bent on both sides and a resin base. The base is a flat guide plate with a general thickness of 3mm-4mm. When worn on the upper jaw, the mandibular anterior teeth bite into the horizontal guide surface, raising the entire occlusal posterior teeth separation by 3-4mm. When worn for a long time, the upper and lower molars will gradually grow, inhibiting the eruption of the mandibular anterior teeth and even depressing the lower anterior teeth, which plays a role in improving the vertical height and sagittal relationship of the maxillofacial region. The zero-space hook plays the role of a fixed orthodontic appliance.

[0004] The Nance support commonly used in the market is an effective and reliable method to enhance support. It is mostly used in the alignment and leveling stages of cases with severe maxillary tooth crowding to maintain the length of the dental arch so that the extraction space is not used by crowded teeth. The shape and structural structure of existing similar products are mainly composed of 2 orthodontic bands on both sides, 1 Nance palatal support, 2 connected steel wires and 10 wire buckles. The orthodontic band plays a role in fixing the position of 7 teeth. The palatal support is a small resin base that contacts the front of the hard palate to prevent the posterior teeth from moving forward and enhance support. Steel wire 1 acts as a lever to withstand the support force of the orthodontic band and the palatal support. 10 wire buckles are pasted on the teeth and strung together by steel wire 2. When the two ends of steel wire 2 are subjected to tension, the distance between the teeth can be adjusted by adjusting the distance between each buckle and the steel wire.

[0005] However, when patients suffer from both crowded teeth and deep overbite, the flat guide appliance and Nance tray cannot effectively treat both symptoms at the same time. Utility Model Content

[0006] The purpose of the utility model is to provide a combined flat guide Nance support brace to solve the problem proposed in the above background technology that when a patient suffers from the symptoms of dental crowding and deep overbite at the same time, the flat guide appliance and the Nance support cannot effectively treat the two symptoms at the same time.

[0007] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a combined flat-guide Nance support corrector, including a resin base, a resin palatal support, a wire buckle, a steel wire one, an orthodontic band ring and a steel wire two, the two ends of the resin base are symmetrically arranged, the resin base is fixedly connected to the teeth through the wire buckle, two orthodontic band rings are provided, and are respectively arranged at the rear end positions on both sides of the steel wire one, the orthodontic band ring is fixedly connected to the steel wire one through the wire buckle, the orthodontic band rings are fixedly connected with the steel wire two, the middle section of the steel wire two is fixedly connected with the resin palatal support, the resin base is fixedly connected with the steel wire three and the steel wire four, and the other ends of the steel wire three and the steel wire four are fixedly connected with the resin palatal support.

[0008] The utility model is further configured such that the portions where the steel wire three and the steel wire four are connected to the resin base are bent in a goat horn shape.

[0009] The utility model is further configured that a fixing ring is provided at one end of the steel wire three and the steel wire four connected to the resin palate support.

[0010] The utility model is further configured that the resin base is made of transparent plastic, and the thickness of the resin base is 3mm-4mm.

[0011] The utility model is further configured that the portion where the second steel wire is connected to the resin palate support is wavy.

[0012] The utility model is further configured such that the orthodontic band rings are respectively arranged on the molar positions on the left and right sides.

[0013] The utility model has the following beneficial effects:

[0014] 1. The resin base is used as a flat guide plate. When worn, the mandibular anterior teeth bite the guide surface, raising the occlusal separation of the posterior teeth, improving the maxillofacial height and sagittal relationship, and the orthodontic band fixes the tooth position. The resin palatal support contacts the hard palate to prevent the posterior teeth from moving forward. The steel wire is used as a lever to bear the support force, and the buckle is attached to the teeth. The distance between the teeth is adjusted by adjusting the distance between the buckle and the steel wire. It is an integrated dual-function orthodontic appliance with a simple structure, beautiful appearance and good correction effect.

[0015] 2. The upper parts of the steel wires three and four connecting the resin base and the resin palatal support are bent into goat horn shapes, and the lower fixing rings are bent into small circles by steel wires, which can effectively prevent debonding and enhance the connection strength. They can effectively fix the resin base and strengthen the supporting effect of the palatal support and have a simple and beautiful shape. The steel wire two is bent into a wavy shape to make the connection between the two orthodontic band rings and the resin palatal support tighter, making the entire appliance more solid and firm. Compared with the prior art, four zero-space hooks are removed, which can effectively reduce the burden on the front teeth. BRIEF DESCRIPTION OF THE DRAWINGS
