Description

Technical Field

[0001] This utility model relates to the field of orthodontic technology, and in particular to an invisible orthodontic appliance with an oblique guide structure. Background Technology

[0002] Traditional orthodontic appliances with angled guidance function use metal brackets and wires for support, which are quite noticeable and easily seen, affecting aesthetics. They may also scratch the oral mucosa, causing pain and discomfort, and may require an adjustment period initially. Due to the presence of brackets and wires, cleaning is relatively difficult, and food debris easily remains, increasing the challenge of oral hygiene.

[0003] Furthermore, traditional orthodontic appliances are manufactured by combining flat guides and inclined channels, resulting in a complex structure.

[0004] Therefore, we designed an aesthetically pleasing and simplified invisible orthodontic appliance that combines both oblique and horizontal guidance functions. Utility Model Content

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: an invisible orthodontic appliance with an oblique guide structure, comprising an appliance body, wherein the anterior teeth of the appliance body are provided with oblique guide blocks, the oblique guide blocks are composed of an oblique surface with specific functions, a connecting transition surface and a supporting surface, the supporting surface being located at the root of the tooth at its lowest point; the oblique guide is at least 1.5mm lower than the anterior teeth, and its oblique angle is between 30 and 45 degrees.

[0006] Preferably, the inclined guide block is a bubble integrally connected to the body of the orthodontic appliance.

[0007] Preferably, the inclined surface of the guide block is located between the two incisors, and the connecting transition surface extends from the lateral incisor through the canine to the root.

[0008] Preferably, the orthodontic appliance body has a transverse jaw bar between its tail ends, which expands or contracts the dental arch.

[0009] Preferably, the transverse jaw bars are integrally formed with the body of the orthodontic appliance.

[0010] The beneficial effects of this utility model are: it is integrated with the invisible aligner, making it almost invisible and aesthetically pleasing; it is relatively smooth, causing less irritation to the oral mucosa; it has a simple structure, is easy to remove and put on by oneself, and facilitates oral cleaning. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0012] like Figure 1As shown, an invisible orthodontic appliance with an oblique guide structure includes an appliance body 1. The anterior teeth of the appliance body 1 are provided with oblique guide blocks 2. The oblique guide block 2 is composed of a functionally specific inclined surface 21, a connecting transition surface 22, and a supporting surface 23. The supporting surface is located at the root of the tooth. The oblique guide is at least 1.5 mm below the anterior teeth, and its inclined surface angle is between 30 and 45 degrees. The oblique guide block 2 is a cavitation structure integrally connected to the appliance body 1. The inclined surface 21 of the oblique guide block 2 is located between the two incisors, and the connecting transition surface 22 extends from the lateral incisors through the canines to the root of the teeth.

[0013] The inclined surface 21 of this invention is a functional surface that contacts the incisal edge of the opposing anterior tooth. It can depress the opposing anterior tooth while simultaneously protruding the mandible to maintain overall mandibular position. It can also accommodate the movement design of the labially inclined opposing anterior tooth to open the occlusal space between the upper and lower jaws. It also possesses the functions of both flat and inclined guidance found in traditional designs.

[0014] The smooth transition design of the connecting surface 22 allows for a smooth transition between the functional surface and the orthodontic teeth, while also providing support and making the force distribution more even and stable.

[0015] The support surface 23 is a vertical support surface, which increases the force on the opposing teeth and can greatly improve the orthodontic effect.

[0016] When using the oblique guide for maxillary placement: The appliance can make more precise contact with the teeth during wear, and the oblique guide structure provides a more stable mandibular labial inclination effect. While the mandibular appliance moves the mandibular anterior teeth labially, it applies external force for labial inclination. It can also protrude the mandible in patients with mild Angle Class II. The third oblique guide structure can also evenly apply intrusive force to the mandibular anterior teeth, avoiding excessive or uneven local pressure that may occur in traditional designs. This effectively prevents problems such as oral ulcers and improves the stability and orthodontic efficiency of the appliance, thus greatly enhancing the wearing experience and accelerating the orthodontic process.

[0017] When using the oblique guide for mandibular retraction: The appliance provides a more stable maxillary labial inclination effect through the oblique guide structure, applying external force for labial inclination while moving the maxillary anterior teeth labially. It can also retract the mandible for mild Angle Class I patients. The third-stage guide structure can also evenly apply intrusive force to the maxillary anterior teeth, avoiding excessive or uneven local pressure that may occur in traditional designs. This effectively prevents problems such as oral ulcers and improves the stability and efficiency of the appliance, thus greatly enhancing the wearing experience and accelerating the treatment process.

[0018] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
