Description

Technical Field

[0001] This utility model relates to the field of orthodontic technology, specifically to an invisible aligner that works in conjunction with anterior tooth retraction and corrects bad lip habits. Background Technology

[0002] Early childhood dentofacial deformities are mainly caused by poor oral habits or functional abnormalities, manifesting as abnormalities in the shape of the dental arch or the positional relationship between the jawbones. In the field of orthodontic treatment, functional orthodontic treatment is a routine treatment for malocclusion symptoms in children and adolescents during the primary and mixed dentition stages. During childhood growth and development, poor oral habits are one of the main causes of malocclusion. Long-term habitual sucking and biting of the lower lip can lead to protrusion of the maxillary anterior teeth, inward tilting and crowding of the mandibular anterior teeth, restricted development of the mandibular arch and mandible, and mandibular retrusion.

[0003] Invisible aligners, also known as bracketless clear aligners, are mostly molded in one piece using compression molding. If functional components need to be added, doctors need to manually install them in conjunction with the aligner, which is troublesome and there is a risk that the functional components may fall off. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section above, some embodiments of this application provide an invisible orthodontic appliance that facilitates anterior tooth retraction and corrects malocclusion, including an upper appliance, a lower appliance, an upper correction mechanism, and a lower correction mechanism on the lower appliance; the upper appliance is in close contact with the upper teeth; the lower appliance is in close contact with the lower teeth.

[0006] Specifically, the upper correction mechanism includes multiple maxillary protrusions.

[0007] Specifically, the lower correction mechanism includes multiple mandibular protrusions.

[0008] Specifically, the maxillary protrusion includes a first occlusal surface, a first end surface, a first corrective surface, and a first annular surface.

[0009] Specifically, the mandibular protrusion includes a second occlusal surface, a second end surface, a second corrective surface, and a second annular surface.

[0010] The beneficial effects of this utility model are:

[0011] (1) The upper and lower orthodontic appliances are respectively equipped with a maxillary protrusion and a mandibular protrusion. The maxillary protrusion and the mandibular protrusion are respectively equipped with a first orthodontic surface and a second orthodontic surface. When the mouth is closed, the first orthodontic surface of the maxillary protrusion is in contact with the labial surface of the maxilla. The labial surface of the maxilla pushes the maxillary protrusion through the first orthodontic surface, accelerating the retraction of the maxillary anterior teeth and increasing the distance between the labial surface and the teeth. The second orthodontic surface of the mandibular protrusion is in contact with the labial surface of the mandible. The labial surface of the mandible pushes the mandibular protrusion through the second orthodontic surface, accelerating the retraction of the mandibular anterior teeth and increasing the distance between the labial surface and the teeth, thus correcting the bad habit of biting the lips with the anterior teeth.

[0012] (2) Existing orthodontic appliances and bubble are molded separately and then assembled by doctors. This manufacturing method is inefficient and the connection is not stable enough. The connection is prone to breakage. The orthodontic appliance and bubble described in this utility model are molded in one piece, which is easy to demold. The connection strength between the bubble and the orthodontic appliance is high and the manufacturing efficiency is high. Attached Figure Description

[0023] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1-3 As shown, the present invention discloses an invisible orthodontic appliance that combines anterior tooth retraction and correction of bad lip habits, comprising an upper orthodontic appliance 1, a lower orthodontic appliance 2, an upper correction mechanism 3, and a lower correction mechanism 4 on the lower orthodontic appliance; the upper orthodontic appliance is closely attached to the upper teeth; the lower orthodontic appliance is closely attached to the lower teeth; the upper correction mechanism is used to correct bad upper lip habits and simultaneously retract the upper anterior teeth; the lower orthodontic appliance is used to correct bad lower lip habits and simultaneously retract the lower anterior teeth.

[0025] Specifically, the upper correction mechanism includes multiple maxillary protrusions 31; the maxillary protrusions are fixed to the anterior teeth portion of the upper orthodontic appliance and are integrally formed during the fabrication of the upper orthodontic appliance. Compared with existing upper orthodontic appliances and maxillary protrusions, it is not necessary to fabricate them separately and then connect them, which improves production efficiency. At the same time, the integral molding increases the connection strength between the maxillary protrusions and the upper orthodontic appliance, preventing the connection from breaking or falling off.

[0026] Specifically, the lower orthodontic mechanism includes multiple mandibular protrusions 41; the mandibular protrusions are fixedly located on the anterior part of the lower orthodontic appliance and are integrally formed during the fabrication of the lower orthodontic appliance. Compared with the existing lower orthodontic appliances and mandibular protrusions, it is not necessary to fabricate them separately and then connect them, which improves production efficiency. At the same time, the integral molding increases the connection strength between the mandibular protrusions and the lower orthodontic appliance, avoiding breakage or detachment at the connection point.

[0027] Specifically, the maxillary protrusion includes a first occlusal surface 311, a first end face 312, a first orthodontic surface 313, and a first annular surface 314. The first occlusal surface is the part that occludes with the upper orthodontic appliance. The first orthodontic surface is an arc-shaped slope. The side of the first orthodontic surface closer to the upper tooth root is narrower, and the side farther from the upper tooth root is wider. From the side view, the side closer to the upper tooth root is shorter, and the side farther from the upper tooth root is wider. This structure facilitates the molding and demolding of the upper orthodontic appliance and the maxillary protrusion in one piece. After the upper orthodontic appliance and the maxillary protrusion are worn, when the mouth is closed, the first orthodontic surface of the maxillary protrusion fits together with the maxillary labial surface, with face-to-face contact. The maxillary labial surface pushes the maxillary protrusion through the first orthodontic surface, accelerating the retraction of the maxillary anterior teeth, while increasing the distance between the labial surface and the teeth, correcting the bad habit of biting the upper lip with the lower anterior teeth.

[0028] Specifically, the mandibular protrusion includes a second occlusal surface 411, a second end surface 412, a second orthodontic surface 413, and a second annular surface 414; the protrusion includes a first occlusal surface 311, a first end surface 312, a first orthodontic surface 313, and a first annular surface 314; the second occlusal surface is the part that occludes with the lower orthodontic appliance; the second orthodontic surface is an arc-shaped slope, with a narrower width on the side closer to the lower tooth root and a wider width on the side farther from the lower tooth root. From the side view, the side closer to the lower tooth root is shorter and the side farther from the lower tooth root is wider. This structure facilitates the molding and demolding of the lower orthodontic appliance and the mandibular protrusion in one piece; after the lower orthodontic appliance and the mandibular protrusion are worn, when the mouth is closed, the second orthodontic surface of the mandibular protrusion fits together with the mandibular labial surface, with face-to-face contact. The mandibular labial surface pushes the mandibular protrusion through the second orthodontic surface, accelerating the retraction of the mandibular anterior teeth, while increasing the distance between the labial surface and the teeth, correcting the bad habit of biting the lower lip with the upper anterior teeth.

[0029] During the manufacturing process, the patient's digital dental model is first reconstructed. Then, the maxillary and mandibular protrusion models are placed on the upper and lower jaw surfaces of the digital dental model. Multiple maxillary and mandibular protrusion models can be set according to the orthodontic needs. The shape, position, and height of the protrusion models can be adjusted according to the orthodontic needs. Boolean processing is performed between the maxillary protrusion model and the maxillary digital dental model to create the contact surface between the maxillary protrusion mold and the maxillary digital dental model. Then, the maxillary protrusion mold is exported and printed as a 3D dental model following the maxillary digital dental model. Boolean processing is performed between the mandibular protrusion model and the mandibular digital dental model to create the contact surface between the mandibular protrusion mold and the mandibular digital dental model. Then, the mandibular protrusion mold is exported and printed as a 3D dental model following the mandibular digital dental model. Through thermoplastic molding, the aligner is pressed onto the 3D dental model of the upper and lower jaws. After a series of processes such as cutting, polishing, and disinfection, the invisible aligner is finally completed.
