Description

Technical Field

[0001] This utility model relates to the field of orthodontic appliance technology, and in particular to an orthodontic appliance that is easy to retain. Background Technology

[0002] In orthodontic treatment, orthodontic appliances are one of the commonly used tools. Traditional appliances typically rely on the mechanical interlocking between the archwire and brackets for retention. Their function is to apply appropriate force to the teeth, guiding them to move to the ideal position, thereby correcting problems such as malocclusion and occlusion. However, traditional orthodontic appliances have many shortcomings in terms of retention.

[0003] Traditional orthodontic appliances rely primarily on friction with the tooth surface and the adhesive strength of the bonding agent for retention. However, the relatively smooth surface of teeth can affect the friction and adhesive strength between the appliance and the teeth, resulting in less than ideal retention. Therefore, developing an orthodontic appliance with better retention is of significant clinical importance. Utility Model Content

The front side of the appliance base has multiple grooves and multiple protrusions fixedly connected to the front side of the appliance base. The back side of the appliance base has an appliance support block fixedly connected to it, and the side wall of the appliance support block has an archwire groove for placing the orthodontic archwire.

[0007] Preferably, the plurality of grooves and the plurality of protrusions are arranged in an alternating vertical arrangement on the front side of the orthodontic base.

[0008] Preferably, the shape of the protrusion includes, but is not limited to, hemispherical, cylindrical, and prismatic shapes, the height of the protrusion is 0.1-1 mm, and the depth of the groove is 0.1-1 mm.

[0009] Preferably, the elastic buckle is made of medical-grade silicone material, and one edge of the elastic buckle is hook-shaped.

[0010] Preferably, the sidewall of the bow wire groove is threaded with bolts.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This device, through the synergistic effect of the protrusions and grooves on the base of the orthodontic appliance and the elastic buckles, forms a mechanical fit with the tooth surface, greatly enhancing the retention force between the appliance and the teeth, effectively reducing the loosening and displacement of the appliance in the oral cavity, and improving the stability and accuracy of the orthodontic treatment.

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described in more detail below by way of example with reference to the accompanying drawings. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] Please see Figures 1-4 In this embodiment of the present invention, an orthodontic appliance that is easy to retain includes an orthodontic archwire 1, on which multiple appliances are mounted. Each appliance includes an appliance base 3. Elastic buckles 4 are fixedly connected to both sides of the appliance base 3. The elastic buckles 4 are made of medical-grade silicone material. One side edge of the elastic buckle 4 is hook-shaped. Multiple grooves 7 are provided on the front side of the appliance base 3. Multiple protrusions 8 are fixedly connected to the front side of the appliance base 3. An appliance support block 2 is fixedly connected to the back side of the appliance base 3. An archwire groove 5 for placing the orthodontic archwire 1 is provided on the side wall of the appliance support block 2. A bolt 6 is threadedly connected to the side wall of the archwire groove 5.

[0024] Multiple grooves 7 and multiple protrusions 8 are arranged vertically and alternately on the front side of the orthodontic appliance base 3. The shape of the protrusions 8 includes, but is not limited to, hemispherical, cylindrical, and prismatic shapes. The height of the protrusions 8 is 0.1-1 mm, and the depth of the grooves 7 is 0.1-1 mm. The alternating vertical arrangement of multiple grooves 7 and multiple protrusions 8 ensures that they are evenly distributed on the front surface of the orthodontic appliance base 3. The grooves 7 and protrusions 8 on the front side of the orthodontic appliance base 3 form a uniform mechanical interlocking effect with the tooth surface. The grooves 7 and protrusions 8 can increase the contact area and friction between the orthodontic appliance base 3 and the teeth, improve the bonding strength, and thus significantly improve the retention effect.

[0025] The working principle of this utility model is as follows:

[0026] First, the adhesive is evenly applied to the front of the aligner base 3 and the elastic clips 4. Then, the front of the aligner base 3, with the adhesive applied, is accurately placed in the predetermined position on the tooth. The grooves 7 and protrusions 8 on the front of the aligner base 3 can increase the contact area and friction between the aligner base 3 and the tooth, improve the bonding strength, and thus significantly improve the retention effect. During placement, the hook-shaped edge of the elastic clips 4 can firmly hook the edge of the tooth, providing additional retention force. After the adhesive is cured by light or chemical curing, the dentist sequentially inserts the orthodontic archwire 1 along the archwire grooves 5 on the back of multiple aligner bases 3, and bends and adjusts the orthodontic archwire 1 as needed to accurately apply orthodontic force to the tooth and guide the tooth to move in the predetermined direction. After the orthodontic archwire 1 is installed, bolts 6 are screwed onto the threaded sidewall of each archwire groove 5. The bolts 6 can limit the orthodontic archwire 1 to prevent it from shifting during the orthodontic process and ensure the stable transmission of orthodontic force.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
