Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of orthodontic device related field, more particularly to a kind of maxillary traction corrector. BACKGROUND

[0002] Maxillary traction corrector is a kind of orthodontic device for treating skeletal class III malocclusion, mainly for patients with maxillary hypoplasia or mandibular hyperplasia. This corrector stimulates the growth and movement of the maxilla by applying external force, thereby improving the occlusal relationship and facial profile of the patient. Traditional extraoral forward traction corrector is composed of intraoral part and extraoral part. The intraoral part is usually a fixed or bonded maxillary expansion appliance with outwardly extending hooks. The extraoral part is a face mask with cushion support for chin and forehead. The hooks of the expansion appliance are connected to the support rods of the face mask by rubber bands, generating forward and downward force to pull the maxilla forward.

[0003] The existing double-bar and single-bar maxillary traction correctors usually adopt metal frame structure. Although the design can provide stable traction force, it has significant limitations. The hard contact points of the metal frame can cause compression to the wearer's head and face, especially when resting or sleeping. This hard contact significantly increases discomfort and may even affect the normal sleeping posture of the wearer. In addition, the weight of the metal frame further reduces the comfort of wearing, especially for children. Therefore, developing a corrector that can eliminate the metal frame and improve the comfort and convenience of wearing is an important direction in the current technical field.

[0004] For example, the utility model patent with application number 201720717248.9, a double-bridge misaligned maxillary canine corrector, is used for the correction of maxillary canine mesial misalignment eruption. The corrector includes bilateral maxillary premolar rings, bilateral maxillary molar rings, bilateral bridges, maxillary canine brackets, stainless steel correction arch wires, and elastic chain rings. The bridge is quadrangular, with the bottom edges of the bridge welded to the buccal surfaces of the bilateral maxillary premolar rings and maxillary molar rings, and the top and bottom edges welded with buccal tubes. The maxillary canine bracket is provided with a groove, and the stainless steel correction arch wire is connected to the buccal tubes on the top or bottom edges of the bilateral bridges. The stainless steel correction arch wire can pass through the groove, and the elastic chain ring is connected to the maxillary canine bracket on one end and to the stainless steel correction arch wire or to the buccal tube on the same side of the maxillary canine bracket on the other end. This corrector can pull the maxillary canine erupted mesially to the distal side of the same side incisor and then vertically to the distal side, finally aligning it in the dental arch without causing trauma to the patient.

[0026] The utility model will be further described below in connection with the drawings and examples;

[0027] As shown in the figure, the mask 1 structure, with rubber pad 10 and correction piece; wherein, rubber pad 10, made of silica gel material, the whole is oval, its edge thickness gradually changes to adapt to the face curve. The inner side surface of the rubber pad 10 is provided with a flexible flange, which is used for closely fitting the face and nose area (including upper lip, ala nasi and below zygomatic bone), forming a sealed space covering the mouth and nose. The outer periphery of the rubber pad 10 is provided with an annular reinforcing rib to enhance the structural stability.

[0028] It should be noted that the rubber pad of the mask is made of oval silica gel material, and the design of gradually changing edge thickness enables it to closely fit the face and nose area. The flexible flange on the inner side surface covers the upper lip, ala nasi and below zygomatic bone, forming a stable sealed space to avoid air leakage or displacement. The softness of silica gel material reduces the pressure on the skin, and the annular reinforcing rib on the outer periphery improves the overall structural strength to prevent deformation. This sealing design not only ensures the effective transmission of traction force, but also avoids the infiltration of unfiltered air from the edge, while the oval contour adapts to the face curve, reducing the displacement of the mask caused by facial activity during sleep.

[0029] The correction piece is fixed to the outer side of the rubber pad 10 (away from the face side), including a protective plate 11 made of medical grade ABS plastic, which is arc-shaped in cross section matching the contour of the mouth and nose, and the arc top protrudes outward. The protective plate 11 is fixedly connected with the outer edge of the rubber pad 10 by ultrasonic welding, and the two together form a closed space. The traction ring 12 is a metal ring, which is welded and fixed to the inner concave side (close to the face side) of the protective plate 11, and two pairs of stainless steel hooks 14 are symmetrically arranged on the inner side of the circumference for connecting the elastic traction belt. The breathing hole 13 is provided on the left and right sides of the protective plate 11, and the breathing hole 13 is embedded with a detachable filter element (such as a melt-blown cloth filter core) for filtering particulate matter and viruses in the air.

[0030] It should be noted that the protective plate of the correction piece is made of medical grade ABS plastic in arc shape, which matches the curvature of the contour of the mouth and nose, and the arc top expands outward to form a containing space. The protective plate is fixed with the outer edge of the rubber pad by ultrasonic welding, and the closed space formed by the two can avoid the direct entry of external air into the mouth and nose through the breathing hole. The traction ring is welded and fixed to the inner concave side of the protective plate, which adopts a metal ring structure to ensure the stability of the traction force, and the stainless steel hooks on the inner side are symmetrically designed to disperse the tension applied by the traction belt, preventing local stress concentration from causing deformation of the protective plate. The breathing hole is provided on the left and right sides of the protective plate, and a plurality of holes with appropriate diameter are provided on each side, and the detachable melt-blown cloth filter core is embedded in the breathing hole, which can filter viruses and particulate matter in the air while ensuring air permeability, reducing the risk of inhaling contaminated air during sleep.

[0031] The fixing member 2 comprises a connecting member, specifically a connecting plate 22, which is a hard plastic plate and is fixedly connected with the outer periphery of the rubber pad 10 through buckling at one end. An extrusion plate 23 is arranged at the other end of the connecting plate 22, and the surface of the extrusion plate 23 is covered with a soft silica gel pad to reduce the compression feeling. An adjusting ring 24 is rotatably connected with the extrusion plate 23 through a rotating shaft, and the surface of the adjusting ring 24 is provided with anti-skid lines. The main belt 20 is two elastic woven belts, and the two ends of the main belt 20 are respectively wound and passed through the two adjusting rings 24, and the length of the main belt 20 is adjusted through a sliding buckle, so that the main belt 20 is used to wrap around the back of the head. The auxiliary belt 21 is a nylon buckle belt, which is transversely connected with the middle sections of the two main belts 20, and the tightness of the auxiliary belt 21 can be adjusted to adapt to different head circumferences.

[0032] It should be noted that the connecting plate of the fixing member is connected with the outer periphery of the rubber pad through buckling of a hard plastic, so that the force transmission path between the mask and the fixing belt is stable. The end of the extrusion plate is covered with a soft silica gel pad, and the adjusting ring connected with the rotating shaft can be rotated to adjust the winding angle of the main belt, so that the hard component does not directly press the face or head. The main belt is made of elastic woven belt material, and the two ends of the main belt are wound around the adjusting ring and then the length of the main belt is adjusted through a sliding buckle. The elastic property of the main belt enables the main belt to adapt to the change of the head posture during sleep, thereby reducing the feeling of being bound. The auxiliary belt is transversely connected with the middle sections of the two main belts through a nylon buckle, thereby forming a stable triangular fixing structure, which disperses the pressure on the back of the head and at the same time adapts to the individual needs of users with different head circumferences. The cooperation of various structures is reflected in the adaptability during night use: the flexible sealing of the rubber pad and the rigid support of the protection plate are combined to make the respiratory airflow concentrate through the filter for processing, thereby avoiding the invasion of viruses; the elastic main belt and the adjustable auxiliary belt ensure the fixing effect while allowing the head to move naturally; the low-resistance design of the breathing hole cooperates with the multi-layer protection of the filter to ensure smooth and safe breathing during sleep. The symmetrical hook design of the traction ring further reduces the probability of deviation of the mask during traction, so that the correction force continuously and stably acts, thereby realizing the dual functions of correction and protection during the whole night wearing.

[0033] In use, the rubber pad 10 of the mask 1 is attached to the face, the main belt 20 of the fixing belt is wrapped around the back of the head, the auxiliary belt 21 is fixed to the top of the head, and the main belt 20 is tightened to an appropriate pressure by rotating the adjusting ring 24. The hook 14 of the traction ring 12 is connected with the teeth inside the oral cavity through an elastic rubber band, and a forward and upward traction force is applied to correct the position of the maxilla. The filter of the breathing hole 13 can be replaced regularly to ensure the functions of ventilation and protection.

[0034] Based on the ideal embodiments of the present application, the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
