Description

Technical Field

[0001] This utility model relates to the field of orthodontic devices, specifically a dental traction device that also functions as a temporary crown. Background Technology

[0002] In orthodontic and restorative treatment, for cases where the tooth root is in good condition but the crown is severely damaged, or where the tooth is completely or partially subgingival due to trauma or caries, orthodontic traction techniques are often used to slowly pull the residual root or low-positioned tooth to a suitable occlusal position for subsequent permanent restoration.

[0003] How to effectively protect the teeth being tractioned, maintain their spacing and aesthetic appearance, and ensure that the traction device functions stably are key issues faced in clinical practice.

[0004] Currently, fixed orthodontic appliances (metal archwires) are mainly used in clinical practice, with adjacent teeth serving as anchorage teeth, and traction is used to assist in root fracture. The metal archwire is metallic in color and not aesthetically pleasing; in addition, the anterior teeth are still in a damaged state, resulting in poor aesthetics, affecting the patient's social life, and the wearing comfort is also poor. Utility Model Content

[0005] The purpose of this invention is to provide a tooth traction device that also functions as a temporary crown, capable of conforming to the shape of the damaged part of the tooth and providing traction force to pull the broken root of the tooth, and is comfortable to wear and aesthetically pleasing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tooth traction device that also functions as a temporary crown, comprising a main crown, an accessory crown, and a metal buckle. The main crown and the accessory crown are integrated. The main crown has a traction hole on the lingual side. An elastic rope is provided between the traction hole and the metal buckle. The metal buckle has a barb. The elastic rope passes through the traction hole and is hooked onto the barb.

[0007] Furthermore, the main crown and accessory crown are made of PMMA resin, ceramic, or a resin-ceramic composite material.

[0008] Furthermore, both the primary crown and the accessory crown are contour-following structures.

[0009] Furthermore, the side of the main crown and accessory crown facing away from the lingual side is provided with a coloring layer.

[0010] Furthermore, the lingual side of the main crown and accessory crown is the bonding surface.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: it can conform to the shape of the damaged part of the tooth and provide traction force to pull the broken root of the tooth, and the overall wearing is comfortable and aesthetically pleasing.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example:

[0018] Please see Figure 1-3 A tooth traction device that also functions as a temporary crown includes a main crown 1, a secondary crown 2, and a metal buckle 3. The main crown 1 and the secondary crown 2 are integrated. The main crown 1 has a traction hole 101 on the lingual side. An elastic rope 4 is provided between the traction hole 101 and the metal buckle 3. The metal buckle 3 has a barb. The elastic rope 4 passes through the traction hole 101 and is hooked on the barb.

[0019] The main crown 1 and accessory crown 2 are made of PMMA resin, ceramic or resin-ceramic composite material, and the wearing comfort of the main crown 1 and accessory crown 2 is relatively good.

[0020] Both the primary crown 1 and the accessory crown 2 are contour-like structures, which are easy to wear and provide better bonding.

[0021] The lingual side of the main crown 1 and accessory crown 2 is covered with a coloring layer. According to the color of the patient's own teeth, pigment is applied to the main crown 1 and accessory crown 2 to make the visual effect more natural after wearing.

[0022] The lingual side of the primary crown 1 and accessory crown 2 is the bonding surface. When bonding, adhesive is applied to the bonding surface before bonding.

[0023] The working principle of this utility model is as follows: During installation, the metal buckle 3 is bonded to the root of the broken tooth. After applying adhesive to the bonding surfaces of the main crown 1 and the accessory crown 2, it is attached to the tooth. The main crown 1 is used to repair the broken tooth. At this time, there is a gap between the traction hole 101 of the main crown 1 and the broken tooth. After the main crown 1, accessory crown 2 and metal buckle 3 are bonded and cured, the elastic rope 4 is passed through the traction hole 101 and tied into a knot, then hooked onto the barb of the metal buckle 3 to keep the elastic rope 4 in a stretched state, ensuring the traction effect. This utility model combines traction and repair functions into one, simplifies the clinical operation process, and can provide physical protection for the patient's broken tooth, preventing further damage. The overall wearing effect is more aesthetically pleasing.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
