Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a cutting end hook retainer. Background Art

[0002] In the field of orthodontics, Halley retainers, as a classic tooth retention tool, have been widely used due to their stable structure, easy operation, and significant effects. However, in actual applications, although ordinary Halley retainers can effectively maintain the correction effect of teeth in most cases, in certain specific cases, such as patients with slightly protruding maxillary anterior teeth, their effects are not satisfactory.

[0003] Specifically, for patients with slightly protruding maxillary anterior teeth, although ordinary Halley retainers can maintain the overall stability of the teeth, due to the lack of a special control mechanism for the maxillary anterior teeth, the anterior teeth continue to grow without any obstruction, making it difficult to maintain the correction effect in the long term. This not only affects the patient's oral aesthetics, but may also have adverse effects on chewing function, pronunciation, etc., causing unnecessary troubles to the patient. Utility Model Content

[0004] The utility model aims to provide an incisal hook retainer to solve the problem that although the Halley retainer proposed in the above background technology has achieved the correction effect when used, the maxillary front teeth are slightly protruding, resulting in the teeth continuing to grow without obstruction.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a cutting end hook retainer, including a resin base, a retaining clip, and a hyperbolic lip bow, the two ends of the hyperbolic lip bow are symmetrically arranged, and the two ends extend to the inside of the resin base for fixed connection, the retaining clip is provided with two, and are respectively arranged at the rear end positions on both sides of the resin base, and are respectively welded and fixedly connected to the two ends of the hyperbolic lip bow, the end of the retaining clip away from the hyperbolic lip bow extends to the inside of the resin base for fixed connection, the hyperbolic lip bow is symmetrically provided with U-shaped curves near the two ends, and a number of cutting end hooks are welded and fixedly connected at the middle section of the hyperbolic lip bow.

[0020] See also Figure 1 and Figure 2 A cutting end hook retainer comprises a resin base 1, a retaining clasp 2, and a hyperbolic lip bow 3. The two ends of the hyperbolic lip bow 3 are symmetrically arranged, and the two ends extend to the inside of the resin base 1 for fixed connection. There are two retaining clasps 2, which are respectively arranged at the rear ends of both sides of the resin base 1, and are respectively welded and fixedly connected to the two ends of the hyperbolic lip bow 3. One end of the retaining clasp 2 away from the hyperbolic lip bow 3 extends to the inside of the resin base 1 for fixed connection. The hyperbolic lip bow 3 is symmetrically provided with U-shaped curves 4 near the two ends, and a plurality of cutting end hooks 5 are welded and fixedly connected at the middle section of the hyperbolic lip bow 3.

[0021] By adopting the above technical solution, the retaining clasp 2 is placed on the molar to ensure the stability of the retainer, the hyperbolic labial bow 3 is located on the outside of the teeth to stabilize the teeth and prevent displacement, and the tooth gap is reduced by adjusting the U-shaped curve 4. The resin base 1 is located on the inside to fix the components and assist in maintaining the stability of the teeth. The incisor 5 is connected to the hyperbolic labial bow 3 and is placed on the first 4 teeth to effectively prevent the growth of the maxillary anterior teeth. The entire retainer has a simple structure and clear functions, and can effectively maintain the tooth correction effect. The steel wire with a diameter of 0.8-1.0mm has high strength and toughness, which can ensure the stability and durability of each component of the retainer. This steel wire can resist the effects of various forces in the oral environment and is not easy to deform or break, thereby ensuring that the retainer effectively maintains the tooth correction effect for a long time. Secondly, the diameter of the steel wire is within this range, which not only ensures sufficient strength, but also avoids discomfort to the patient due to excessive diameter. The appropriate steel wire diameter can ensure that the retainer is highly comfortable when worn, reduce friction and stimulation to the patient's mouth, and improve the patient's wearing experience. In addition, the retaining clasp 2 can be firmly placed on relatively strong and solid teeth (i.e. molars) through the strength and toughness of the steel wire, thereby stabilizing the entire retainer. The hyperbolic labial bow 3 and the incisal hook 5 also rely on the excellent performance of the steel wire to achieve the functions of stabilizing teeth, preventing tooth displacement, and effectively preventing the growth of maxillary anterior teeth. These components work together to ensure the durability of the tooth correction effect.

[0022] The U-shaped curve 4 is set in a U shape, the resin base 1 is made of transparent plastic, and the thickness of the resin base is not less than 2mm, the retaining clasp 2, the hyperbolic lip bow 3, and the cutting end hook 5 are all made of steel wire with a diameter of 0.8-1.0mm, and the retaining clasp 2 is respectively arranged on the molar positions on the left and right sides, and four cutting end hooks 5 are arranged, and the top end of the cutting end hook 5 is clamped on the incisor to achieve effective control of the front teeth.

[0023] By adopting the above technical solution, the thickness of the resin base 1 is a key factor in ensuring its structural stability. Sufficient thickness can provide stronger support, so that the base can stably fix the teeth and other components in the oral environment to prevent displacement or falling off. This is crucial to the long-term effectiveness of the retainer and the oral health of the patient. Secondly, the resin base 1 also helps to improve the durability of the retainer. During daily oral activities such as chewing and talking, the teeth and retainers are subjected to various forces. Thicker resin bases can better resist the effects of these forces and reduce deformation or damage caused by external forces, thereby extending the service life of the retainer.

[0024] According to the working principle of the utility model, although the Halley retainer has achieved the correction effect when used, the maxillary anterior teeth are slightly protruding, resulting in the continuous growth of the teeth without obstruction. The incisal hook retainer is composed of two retention clasps 2, a hyperbolic lip bow 3, four incisal hooks 5 and a resin base 1, wherein the retention clasp 2, the hyperbolic lip bow 3 and the incisal hook 5 are all made of bent steel wires. The retention clasp 2 is generally placed on relatively strong and solid teeth (i.e. molars) to maintain the stability of the teeth and the entire retainer. The hyperbolic lip bow 3 is placed on the outside of the teeth to stabilize the teeth and prevent the teeth from shifting, and the U-shaped curve 4 is adjusted to achieve the effect of reducing the tooth gap. The resin base 1 is placed on the inside of the teeth to fix the retention clasp 2 and the hyperbolic lip bow 3, and can also assist in maintaining the stability of each tooth. The incisal hook 5 is connected to the hyperbolic lip bow 3 and is placed on the front 4 teeth, which can effectively prevent the growth of the maxillary anterior teeth.
