Description

Technical Field

[0001] The utility model relates to the technical field of oral medical devices, in particular to a removable vertical activator. Background Art

[0002] Activators are mainly applicable to the correction of oral teeth. Their function is to promote jaw development and craniofacial growth by changing the functions of orofacial muscles, mainly relying on growth potential to cause remodeling of the TMJ, jaws, and alveolar processes.

[0003] Existing activators generally consist of a labial bow and a resin baseplate. The labial bow is placed outside the upper anterior teeth and can effectively inhibit the protrusion of the upper anterior teeth. The resin baseplate is placed inside the oral cavity, with convexities on both the upper and lower sides and a tooth bite mark groove in the middle. However, the groove as a whole moves forward. During chewing, the orofacial muscles drive the entire mandible forward to align with the tooth groove mark under the guidance of the convex part of the baseplate, which can effectively improve mandibular retrusion.

[0004] Currently, when correcting maxillary protrusion, a headgear activator is generally used for correction. Under the action of the backward traction force of the extraoral traction device, the upper anterior teeth are forced to contract inward, better inhibiting the protrusion of the upper anterior teeth.

[0005] However, during the treatment process of the above activator, the control of the vertical height of the lower posterior teeth is a difficult point. If the height of the lower posterior teeth can be depressed to achieve reverse rotation of the mandible, the small chin appearance of the patient can be improved, further enhancing the correction effect. However, the current headgear activator cannot achieve this effect.

[0006] In the prior art, in a patent for an arch-expanding activator for correcting class II malocclusion (publication number: CN105726143A), although vertical wing plates are provided at the palatal baseplate in the palatal part of the oral palate and at the position on the lingual side of the lower dentition, it cannot effectively control the vertical height of the lower posterior teeth and cannot achieve reverse rotation of the mandible and the effect of improving the small chin appearance of the patient. Summary of the Utility Model

[0007] Aiming at the problems existing in the background art, a removable vertical activator is proposed.

[0008] The present utility model provides a removable vertical activator, which includes a resin base, a labial bow and fixed clasps. The labial bow is arranged on the resin base and is used to prevent the anterior teeth from further protruding forward. The fixed clasps are arranged on the resin base, are arranged in pairs and symmetrically, and are used to fix the entire activator on the teeth. An alveolar ridge is arranged on the resin base and is used for the stability when a single tooth bites with the resin base, so as to prevent the resin base from moving in the oral cavity. Two buccal tubes are arranged on the resin base, and an extraoral traction device is arranged on the resin base. The extraoral traction device is connected to the two buccal tubes. A part of the extraoral traction device extends to the outside of the oral cavity, and the extraoral traction device is in a detachable state. The extraoral traction device is used to pull the resin base to press down the lower posterior teeth and control the height of the lower posterior teeth.

[0009] Preferably, the fixed clasps are buckled on the molars.

[0010] Preferably, a palatal arch is arranged on the inner side of the resin base and is used to play an anchorage role to prevent the labial bow from contracting inward.

[0011] Preferably, the alveolar ridge of the part of the resin base in contact with the mandibular teeth is arranged in an inclined plane. During chewing, the facial muscles drive the whole mandible to move forward under the guidance of the alveolar ridge of part of the resin base, so as to improve mandibular retrusion.

[0012] Preferably, an installation groove is formed in the alveolar ridge corresponding to the posterior lower teeth facing the mandible. A fixing frame is arranged in the installation groove, a lower pressing plate is slidably installed in the fixing frame, a part of the lower pressing plate extends outside the fixing frame, a pressing spring is arranged in the fixing frame, the pressing spring is connected to the lower pressing plate, and a resin plate is arranged on the side of the lower pressing plate away from the fixing frame.

[0013] Preferably, the retractable length of the lower pressing plate in the fixing frame is 1-2 mm, and a downward pressure is applied to the posterior lower teeth through the lower pressing plate.

[0014] Preferably, palatal beads can be added at the palatal arch to increase the exercise of the tongue muscles and correct bad tongue habits.

[0015] Compared with the prior art, the present utility model has the following beneficial technical effects:

[0016] This activator has the function of being used both day and night and can effectively shorten the treatment time. At the same time, the existing fixed extraoral traction device is replaced with a removable extraoral traction device. When there is no chewing at night, the extraoral traction device can also drive the resin base to press down the lower posterior teeth through the acting force at the connection with the buccal tube, so as to achieve the effect of mandibular counterclockwise rotation and shorten the treatment time.

[0017] This activator adds a palatal arch, which can form an anchorage role and effectively prevent the labial bow from narrowing due to the inward contraction under force.

[0018] The present activator is provided with a lower pressing plate and a resin plate in the alveolar socket of the lower posterior teeth, so as to form a convex point in the corresponding alveolar socket. When the teeth bite the resin base, a downward pressure can be given to the lower posterior teeth, achieving an effect similar to that of installing an extraoral traction device. When using the activator during the day, the lower posterior teeth can also be pressed down to achieve the effect of mandibular retroversion, shortening the orthodontic time.

Detailed Embodiment

[0024] As Figures 1-4 shown, a removable vertical activator proposed by the present utility model includes: a resin base 1, a labial arch 6, a fixing clasp 3, an alveolar socket 2, a buccal tube 4 and an extraoral traction device 5.

[0025] As Figures 1-4 shown, the labial arch 6 is arranged on the resin base 1 and is used to prevent the anterior teeth from further protruding forward. The fixing clasp 3 is arranged on the resin base 1. The fixing clasps 3 are arranged in pairs and symmetrically, and are used to fix the entire activator on the teeth. The fixing clasp 3 is buckled on the molars. Generally, the molars in the teeth are relatively strong, ensuring the installation stability of the entire activator; the alveolar socket 2 is arranged on the resin base 1 and is used for the stability when a single tooth bites the resin base 1, avoiding the resin base 1 from moving in the oral cavity; two buccal tubes 4 are arranged on the resin base 1, and an extraoral traction device 5 is arranged on the resin base 1. The extraoral traction device 5 is connected to the two buccal tubes 4. A part of the extraoral traction device 5 extends to the outside of the oral cavity, and the extraoral traction device 5 is in a detachable state. Rubber caps 8 are arranged at both ends of the extraoral traction device 5 outside the oral cavity, and the connection stability between the extraoral traction device 5 and the headgear can be improved through the rubber caps 8.

[0026] As Figure 1As shown, a palatal arch 7 is provided on the inner side of the resin base 1 to serve as an anchorage to prevent the labial arch 6 from contracting inward. Palatal beads can be added at the palatal arch 7 to increase tongue muscle exercise and correct bad tongue habits.

[0027] As Figures 1-2 shown, the alveolar part 2 where the resin base 1 contacts the mandibular teeth is provided with an inclined surface. During chewing, the facial muscles drive the entire mandible to move forward under the guidance of the resin base 1 and the alveolar part 2 to improve mandibular retrusion.

[0028] As Figures 2-4 shown, an installation groove 9 is formed in the alveolar part 2 corresponding to the posterior lower teeth facing the mandible. A fixing frame 10 is arranged in the installation groove 9. A lower pressing plate 11 is slidably installed in the fixing frame 10. A part of the lower pressing plate 11 extends outside the fixing frame 10. A lower pressing spring 13 is arranged in the fixing frame 10. The lower pressing spring 13 is connected to the lower pressing plate 11. A resin plate 12 is arranged on the side of the lower pressing plate 11 away from the fixing frame 10. The retractable length of the lower pressing plate 11 in the fixing frame 10 is 1 - 2 mm. Through the telescopic setting of the lower pressing plate 11, with the cooperation of the lower pressing spring 13, the resin plate 12 can better contact the posterior lower teeth, thereby better applying a downward pressure to the posterior lower teeth.

[0029] As Figures 1-2 shown, the A surface of the resin base 1 faces the maxillary teeth, and the B surface faces the mandibular teeth.

[0030] In this embodiment, the activator is divided into two modes: daily use and night use. In the daily use state, the extraoral traction device 5 can be not installed. The specific usage operation is as follows: The resin base 1 can be installed on the maxillary teeth of the oral cavity through the fixing clasp 3, and the labial arch 6 is used to prevent the anterior teeth from further protruding forward to achieve a tooth correction effect;

[0031] During use, the extraoral traction device 5 can be installed on the buccal tube 4 on the resin base 1. Then, a headgear and a traction belt can be worn outside, and the headgear is connected to the extraoral traction device 5 through the traction belt. The headgear pulls the traction belt obliquely upward and obliquely backward, and the traction belt pulls the extraoral traction device 5, thereby pulling the entire activator to pull the maxillary anterior teeth, inhibiting the forward development of the maxilla, moving the protruding maxilla backward to achieve the correction effect; at the same time, since the activator is worn on the maxillary teeth, the connection position between the buccal tube 4 and the resin base 1 can apply a downward reaction force to the posterior lower teeth under the action of the resin base 1 when the patient closes the mouth and bites, pressing down the posterior lower teeth at the connection between the resin base 1 and the lower posterior teeth. By pressing down the posterior lower teeth, the mandible can be reverse rotated to control the height of the posterior lower teeth, thereby improving the correction effect and shortening the correction time at the same time;

[0032] Meanwhile, during daily use, when biting the resin base 1, the lower pressing plate 11 and the resin plate 12 contained in the alveolus 2 of the resin base 1 facing the lower posterior teeth come into contact with the lower posterior teeth. During this process, the biting force of the oral teeth is received on both sides of the resin base 1. Due to the protrusion of the lower pressing plate 11 and the resin base 1, the biting force received by the lower posterior teeth is increased, so that a relatively separate downward pressure can be given to the lower posterior teeth, achieving the effect of pressing down the lower posterior teeth. It has the same effect as installing the extraoral traction device 5, causing the mandible to rotate counterclockwise, achieving the control of the height of the lower posterior teeth, thereby improving the orthodontic effect and shortening the orthodontic time at the same time.

[0033] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to this. Various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those skilled in the art.
