Apparatus for the treatment of deep bite

 

(57) Abstract:

The invention relates to medicine, namely to orthodontics.com devices. The inventive apparatus for the treatment of deep bite contains a removable base plate 1 with 2 clasps on the first molars, which in the front part contains the springs, made in the form of T-shaped wire loops with 3 bends in the horizontal and vertical planes of elastic material, the bending of which invest removable transparent Kappa 5 for blades undergoing dentoalveolar intrusion.

The invention relates to medicine, and more particularly to orthodontic devices, and is intended for treatment of deep bite, mainly due to dentoalveolar lengthening in the region of the incisors.

Deep bite is one of the more common dental anomalies in children and adults, which is difficult to fix the known devices.

Known apparatus for the treatment of deep bite, containing basic plastic plate on the upper jaw with Nakonechny ground for the introduction of lower incisors and clasps in the posterior teeth.

Disadvantages:

the device does not spolia, led to the formation of a deep bite;

the apparatus causes the overload and injury of the lower incisors, especially in children with unformed roots;

the duration of orthodontic treatment (more than two years).

There is also known a device for the treatment of deep bite, containing a removable base plate with nakonechnyi sites in the field of dairy molars.

Its disadvantage is that the apparatus does not contribute dentoalveolar implementation in the area of the anterior teeth.

As a prototype of the selected device for the treatment of deep bite - plate Katz containing base plate on the upper jaw of the inclined plane and toggle clasps in the area of the incisors, which are used for the treatment of distal deep bite.

The disadvantages of the prototype:

the device does not provide dentoalveolar implementation in the area of the upper and lower incisors;

causes injury cutters toggle clasps and erasing enamel;

causes of vestibular deviation of the lower incisors on an inclined plane;

the duration of treatment (two years or more).

The aim of the invention is to increase the efficiency of treatment of deep bite, dostizeni goal is achieved by the apparatus for the treatment of deep bite, contains a removable base plate with clasps on the first molars, which in the front-tooth region supplied with springs made in the form of T-shaped wire loops with curves in horizontal and vertical planes of elastic material providing dentoalveolar intrusion in the area of the cutters in the bend which invest removable transparent Kappa for cutters. Eliminating direct contact with the enamel of incisors with loops-springs attained such a design of the device, eliminates their injury, and at the same time, the T-shaped spring provides constant pressure on the teeth, covered with Kappa, thereby contributing to the transformation and normalization occlusion and treatment.

In Fig. 1 shows a device, a General view of Fig. 2 - the same, lateral view (arrows indicate the direction of dentoalveolar intrusions and direction of activation of the springs), and Fig. 3 is a view from the side of the oral cavity (separate trays for upper and lower teeth).

The proposed device for the treatment of deep bite contains a base plate 1 with 2 clasps on the molars, with T-shaped hinges-spring 3 along cutters, putting pressure in the vertical direction, the bends.

Operating part of the apparatus are springs on cutters that are coming out of the base plate are one knee spring in the middle of the tooth crown with palatal side, cross cutting edge and climb the height of the cutter, forming over the neck of the tooth T-shaped curve, then down the second knee down on the tooth, repeating the first knee of the wire, then form a bend in the transversal plane and the spring and end in the base plate.

The spring apparatus is activated twice a week yourself sick over the top of the T-curve, and when the testimony and oral direction for curves in the transversal plane. The device is worn continuously, except for meal times.

The use of this apparatus provides an opportunity dosed dentoalveolar introduction in the anterior upper and/or lower jaw, excludes injury to the teeth and periodontium, abrasion cutters, provides good fixing apparatus, increases the efficiency of treatment of deep bite, reducing its terms.

Clinically proven realignment and normalization of occlusion while wearing the apparatus of this construction with reduction of terms of treatment is the area of the incisors in patients with deep bite, due to dentoalveolar lengthening in the region of the incisors, which was affected by the T-shaped springs. On average, four weeks can cause dentoalveolar shortening the height in the area of the incisors 1,5 mm

A comparison of the proposed device with the prototype showed the following advantages are presented in the table.

In addition, the claimed apparatus eliminates the vestibular deviation of the lower incisors, as the design of the device there is an inclined plane, and does not cause abrasion of the enamel of incisors, due to their isolation Kappa from active-active T-shaped springs.

FIELD: medicine.

SUBSTANCE: method involves opening palatine suture to normal palate shape with slight width hypercorrection of superior dentoalveolar arch. Device having cap covering parietooccipital area, rubber braces, facial arch composed of intraoral arch and two lateral extraoral parts. Intraoral arch ends are fixed on the sixth maxillary teeth. The device is applied for acting with forth directed upwards and backwards towards the crown of head. A force is applied to the sixth maxillary teeth arranged symmetrically relative to the palatine suture. Force of 300 to 400 g is applied to each side of the maxilla for 12-14 h per day to reach occlusion normalization in sagittal and vertical plane.

EFFECT: accelerated treatment course; improved cosmetic results.

SUBSTANCE: method involves carrying out gingiva retraction, forming L-shaped notches on central incisors medial surface and cutting edges. L-shaped reinforcing members produced in advance in conformance with the notches are arranged in the notches filled with fluid composite. The reinforcing members are set 1-1.5 mm below incisor cutting edges level. Guided polymerization of vestibular, oral and cutting surfaces being over, diastem is eliminated by coating medial surface of incisors layer-by-layer with composite material selected for being applied to frontal teeth group. The central incisors are polished and cutting edge is adjusted to recreate anatomical shape.

EFFECT: enhanced effectiveness of treatment.

SUBSTANCE: method involves carrying out X-ray examination and determining longitudinal axis tilt of retained tooth and computer tomography. Maxillary computer tomography is carried out in three-dimensional Descartes coordinates with central occlusion being preliminarily fixed with individual silicon gumshield. The gumshield has 2-4 mm thick bilateral occlusion surface. Calculated free space value being found greater than thickness (vestibulo-oral size) of the retained tooth, positive prognosis for successful moving out is determined by building geometrical model, carrying out mathematical analysis of received data. The calculated free space value being found equal to retained tooth thickness, prognosis for difficult moving out is produced. The calculated free space value being found less than retained tooth thickness, unfavorable prognosis for moving out is produced.

EFFECT: high accuracy in predicting orthodontic correction results in three-dimensional space.
