Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to a vertical control device for orthodontic treatment of children in dentition period.
Background
The high angle of the mandibular plane angle of children is a misjaw deformity with abnormal development of mandible in the vertical direction, and is often accompanied with a sagittal bone type II misjaw. The high-angle infant has the advantages that the mandible grows excessively in the vertical direction, the front face is higher than the rear face, the mandible plane rotates clockwise to cause overlong lower parts, the appearance of the jaw face is affected due to the fact that the hyoid bone and the tongue body are located at the rear, the upper airway is easy to narrow, sleep breathing disorder is caused, and the general health of the infant is adversely affected.
In orthodontic clinic, if a bone type II patient is accompanied with high angle deformity, the treatment difficulty is obviously increased. For patients with permanent dentition, the vertical control technology of the implant nails is often used for camouflage treatment, or combined treatment of orthodontic-orthognathic surgery is relied on after the adult. For patients in the growth and development peak or the pre-peak period, the treatment is mainly to correct the sagittal imbalance of the jawbone and simultaneously change the growth direction of the mandible, namely, the vertical control technology reduces the severity of high angles and reduces the later treatment difficulty.
However, the prior art has limited orthodontic treatment means and has very little general effect on the group II osseous children with high angles in the dentition period. When the functional appliance is worn, teeth elongation of different degrees can occur at the same time of correcting sagittal development disorder of the jawbone, so that the jawbone rotates clockwise, the angle of the plane of the jawbone is increased, and the angle of the jawbone is worsened, so that serious angle of the jawbone is a relative contraindication of the functional appliance. In addition, the existing dentition period vertical control device is an extraoral device, such as an extraoral arch-head cap, has larger volume and poor comfort, needs to rely on the cooperation of patients, and is difficult to achieve the expected effect if the compliance of the patients is not high.
Disclosure of Invention
The invention aims to overcome at least one of the defects in the prior art and provide a vertical control device for orthodontics for children in dentition period, which can greatly reduce the difficulty of late stage camouflage treatment and reduce the probability of adult orthognathic surgery. After the device is worn on the affected side, the upper jaw front teeth are actively depressed, the first molar teeth are elongated, the upper jaw running-in plane rotates anticlockwise, the lower jaw front teeth are controlled to grow vertically, and the vertical growth of the lower jaw bone is changed.
The aim of the invention can be achieved by the following technical scheme:
a vertical control device for orthodontics of children in dentition period comprises an upper jaw vertical control component and a lower jaw vertical control component;
the maxillary vertical control assembly comprises:
a connecting body;
casting crowns arranged at two ends of the connecting body and fixed on the breast teeth of the patient;
a buccal tube disposed on the buccal side of the cast crown;
the traction hook is arranged on the casting crown and extends to the maxillary anterior tooth area;
the mandibular vertical control assembly includes:
a base which is abutted with the lingual side;
the arrow clamps are arranged at the two sides of the base and clamped in the mandibular teeth grinding areas at the two sides, so that the retention is realized;
a labial arch arranged in the middle of the base, wherein the labial arch is used for preventing the labial inclination of the anterior mandible;
and the adjacent hooks are arranged in the middle of the base, prevent the extension of the anterior mandible and strengthen retention.
In one embodiment of the invention, the connector is a palate support or an expander, which can fix and strengthen the overall resistance of the upper jaw.
Preferably, the expander is a spiral expander.
In one embodiment of the invention, the thickness of the casting crown is 0.3-1mm.
In one embodiment of the invention, the towing hook is a stainless steel wire with a cross-sectional circle diameter of 0.8-2 mm. The traction hook is connected with an arch wire in the dental arch through an elastic rubber chain to have integral depression effect on the upper front teeth, the occlusion is opened due to the thickness of the casting crown in the wearing process, the first molar is elongated, and then the effect of enabling the maxillary dentition plane to rotate anticlockwise is achieved.
In one embodiment of the invention, the cast crown is welded to the buccal tube.
In one embodiment of the invention, the buccal tube is provided with a hollow tube through which the corrective archwire may be secured for ease of passage of the corrective archwire.
More specifically, buccal tubes (brackets) welded to the buccal sides of the double-sided cast crown may allow the corrective archwire to pass through the hollow tube thereof, thereby serving to secure the corrective archwire.
In one embodiment of the invention, the arrow-shaped clip is annular, and the retention is achieved by a clip on a bilateral mandibular molar area.
In one embodiment of the invention, a bending adjusting part is arranged at one end of the labial arch, which is close to the base, and the bending adjusting part is positioned at the outer side of the base.
In one embodiment of the invention, both ends of the adjacent hooks and the arrow cards are embedded in the base, and the hook cards of the adjacent hooks and the hitching parts of the arrow cards are positioned at the outer sides of the corresponding base.
Compared with the prior art, the invention has the following advantages:
(1) The existing dentition period vertical control device is an extraoral device, such as an extraoral arch-head cap, has larger volume and poor comfort, is generally worn only at night, needs to rely on the cooperation of patients, and is difficult to achieve the expected effect if the compliance of the patients is not high. The device designed by the invention is an intraoral device, can be worn all day, can ensure the treatment effect,
(2) The existing vertical control device for the dentition period does not relate to correction of anterior teeth, has no correction effect on deep occlusion of the anterior teeth, and has limited left and right rotation on the upper jaw plane and the lower jaw plane. The invention can depress the upper anterior teeth, control the growth of the lower anterior teeth, improve the deep dental occlusion and achieve obvious effects of contra-rotating dental occlusion surface and mandibular plane.
(3) Serious high angles are relative contraindications of the functional appliance, and a large number of patients needing functional correction can only be treated in a suspending way due to the high angles, wait for the treatment of the permanent dentition period to be disguised by using the implanted nail anchorage technology, and even treat the adult posterior orthognathic surgery. The device designed by the invention is reversely screwed on a plane, so that the growth of the lower jaw is changed, the difficulty of orthodontic treatment in the dentition period can be obviously reduced by the later-stage combined functional appliance treatment, and the risk of orthognatic operation is reduced.
