Description

Technical Field

[0001] This utility model relates to the field of oral medical device technology, and in particular to an adjustable wire loop gap maintainer. Background Technology

[0002] Premature loss of primary teeth during childhood due to various reasons may cause adjacent teeth to tilt towards the gap and opposing teeth to elongate, which may affect the normal eruption of the permanent teeth and cause malocclusion. Similarly, for children who are growing and developing, early loss of permanent teeth may also cause adjacent teeth to shift, leading to malocclusion.

[0003] Currently, the main method commonly used in pediatrics to prevent changes in edentulous space caused by premature loss of primary teeth is the fabrication of a coil-type space maintainer. For example... Figure 6 The diagram shows the structure of an existing wire-coil gap retainer, which consists of a band and a blocking wire. The band serves a retention function, while the blocking wire supports the edentulous space. The existing method for bending and placing the blocking wire is as follows: a 0.8mm stainless steel wire is bent into a concave shape using pliers. The center of the concave shape is then placed against the mesial adjacent tooth of the edentulous space. Next, the wires on both sides of the concave shape are bent towards the distal abutment tooth of the edentulous space using pliers, forming a uniform arc 0.5mm away from the tissue surface during its movement. After contacting the buccal-lingual angle of the band of the abutment tooth, the wire is welded.

[0004] However, the aforementioned coil-type space maintainers have certain drawbacks and shortcomings: First, fabrication requires a certain period of time. If the successor tooth fails to erupt soon, the continued growth of the two adjacent teeth will cause the gap to narrow. The curvature of the retaining wire in the fabricated coil-type space maintainer is fixed and difficult to adjust, which means the maintainer cannot be properly positioned and must be remade, prolonging the tooth loss period. Second, there will always be some degree of error in taking and casting the model, affecting the accuracy of the model. The maintainer fabricated based on the model is difficult to adjust, which in turn affects the support of the edentulous space. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable wire loop gap retainer, which solves the problem mentioned in the background art that the existing wire loop gap retainer requires a certain period of time to manufacture. If the successor tooth fails to erupt in the near future, the gap becomes smaller, or there are errors in the manufacturing process, the manufactured wire loop gap retainer cannot be successfully positioned.

[0006] The present invention adopts the following technical solution:

[0007] This utility model discloses an adjustable wire loop gap retainer, including a belt ring, a blocking wire fixedly connected to one side of the belt ring, the blocking wire including a support part for supporting adjacent teeth, a deformation adjustment arm provided between the support part and the belt ring, and a connecting part provided at both ends of the deformation adjustment arm, one of the connecting parts being fixedly connected to the belt ring, and the other connecting part being fixedly connected to the support part.

[0008] Furthermore, the support portion is an arc-shaped structure that fits into adjacent teeth.

[0009] Furthermore, the deformation adjustment arms are configured as two, and the two deformation adjustment arms are respectively arranged on the inner and outer sides of the jawbone.

[0010] Furthermore, the deformation adjustment arm is U-shaped.

[0011] Furthermore, the U-shaped opening of the deformation adjustment arm faces upward.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] This invention adds a U-shaped curved adjustment arm to the buccal and lingual sides of the blocking wire of a coil-type gap maintainer. The arm's width can be adjusted to accommodate gaps in the missing teeth, making installation smoother. This avoids problems caused by the gap narrowing due to the immediate failure of the successor tooth to erupt, the continued growth of adjacent teeth, or manufacturing errors that could prevent installation.

[0022] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 5 As shown, this embodiment discloses an adjustable wire loop gap retainer, including a belt loop 1, which is fixed on the abutment tooth 3 of the edentulous gap. A blocking wire 2 is fixedly connected to the side of the belt loop 1 facing the edentulous gap. The blocking wire 2 is used to abut against the mesial adjacent tooth 4 of the edentulous gap.

[0024] The blocking wire 2 includes a support part 2-1 for supporting the mesial adjacent tooth 4. A deformation adjustment arm 2-2 is provided between the support part 2-1 and the belt ring 1. Both ends of the deformation adjustment arm 2-2 are provided with connecting parts 2-3. One connecting part 2-3 is fixedly connected to the belt ring 1, and the other connecting part 2-3 is fixedly connected to the support part 2-1.

[0025] The support part 2-1 is an arc-shaped structure that fits against adjacent teeth. Two deformation adjustment arms 2-2 are provided, and the two deformation adjustment arms 2-2 are respectively arranged on the inner and outer sides of the jawbone. The deformation adjustment arms 2-2 are U-shaped. The U-shaped bending direction of the deformation adjustment arms 2-2 is vertical, and the U-shaped opening faces upward. The design of the U-shaped deformation adjustment arms 2-2 allows for adjustment of their width to accommodate edentulous gaps, ensuring smooth installation of the device.

[0026] The manufacturing method of this utility model is as follows:

[0027] First, band 1 is fabricated. A dental model is taken from the patient's mouth and the model is trimmed. Then, the maximum circumference of the abutment tooth 3 is measured with copper wire, and band 1 is fabricated on the abutment tooth 3 model.

[0028] Next, the blocking wire 2 is fabricated by bending a 0.8mm stainless steel wire into a concave shape. The center of the concave shape is then placed against the proximal surface of the mesial adjacent tooth 4 in the edentulous space to complete the support part 2-1. The wires on both sides of the support part 2-1 are then bent towards the abutment tooth 3 in the edentulous space. When the wire crosses the middle of the buccal and lingual sides of the edentulous space, a U-shaped bend is added at this point using trapezoidal pliers to create the deformation adjustment arm 2-2. The deformation adjustment arm 2-2 is evenly separated from the mucosa, forming an arc that is evenly separated from the tissue surface by 0.5mm, contacting the buccal and lingual corners of the band 1. The blocking wire 2 is welded to the buccal and lingual corners of the band 1, then ground and polished. The clinician then tries the fabricated device in the patient's mouth to check the contact between the wire loops and the teeth and mucosa. Finally, it is bonded to the teeth with adhesive, completing the fitting process.

[0029] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
