The orthodontic bracket

 

(57) Abstract:

The invention relates to medicine and can be used in dentistry, in particular orthodontists. The housing has a groove for the orthodontic arch and attached the hook, the axis of which is perpendicular to the axis of the groove and the symmetric axis of the bracket containing the substrate. The groove is egulirovannyh inclusionism, and the monolithic body. The hook is formed of an elongated body portion with a spherical end, and made to commit duchaussoy elastic traction. The result is improved manufacturability and reliability in the up-, and postoperative immobilization periods, you have the option of using braces not only for orthodontic treatment and achieved stillness of the teeth. 1 Il.

The invention relates to medicine and can be used by dentists and in particular orthodontists.

Known orthodontic braces, which is a substrate and two buildings, located parallel to the axis of the tooth, with the working grooves for positioning the orthodontic arch (see A. C. USSR N 1634265, A 61 C 7/00 and U.S. patent N 4681538).

The disadvantages of these devices are low rigidity; when loading is snasti is "Block for the dental arch for the correction of poorly aligned teeth" (French patent N 2680097), consisting of a substrate and two blocks with grooves for positioning the orthodontic arch and a pin mounted on one of the buildings used as a hook for elastic rods.

The main disadvantage of the above-mentioned technical solutions adopted for the prototype is the ability to use only for orthodontic treatment; in addition, it leads to tooth mobility.

The aim of the present invention is to remedy these disadvantages, improving manufacturability and reliability in the up-, and postoperative immobilization periods.

This objective is achieved in that the housing bracket is made of monolithic, single ingalirovanna and inclusionism groove, and the lower or upper part of the body (upper or lower teeth) is elongated and forms a monolithic powerful hook, the axis of which is perpendicular to the axis of the groove and the symmetric axis of the bracket, which allows the use of up-, and postoperative immobilization periods after costaccounting operations.

Conducted patent research and analysis of the known technical solutions allow us to conclude that at present there are no known technical solutions with similar ASS="ptx2">

The drawing shows a bracket containing the substrate 1, the monolithic body 2 with orthodontic groove 3 and cast a hook 4, located on the axis of the housing perpendicular to the groove.

The orthodontic bracket is as follows:

the substrate 1 with a housing 2 mounted on a vertical surface of the teeth, the arc is introduced into the groove 3, fix a ligature to them.

After surgery impose duchaussoy elastic rod fixed to a hook 4.

Braces are used for orthodontic treatment before surgery, immobilization period after costaccounting surgery and in the postoperative orthodontic treatment.

This bracket is used in Russia and in the CIS countries for the first time.

Now used in the treatment wire bus with sazanami hooks (bus Vasiliev), copper alloys, passing between the teeth, causing damage to the soft tissues of the oral cavity (bleeding), and tooth mobility. We offer braces eliminate these shortcomings.

The orthodontic bracket containing a substrate, a housing with a recess for the location therein of the orthodontic arch and fixed to the body of the hook, the axis of which is perpendicular to bus made monolithic, moreover, the hook is formed of an elongated body portion, provided with a spherical end and made to commit duchaussoy elastic traction.

SUBSTANCE: before orthopantomogram performance at the stage of patient examination, a bond is applied preliminary on the dry surfaces of each tooth from the vestibular side of the tooth. Then, thin wire guides with a diameter of 0.1-0.3 mm are laid on the vestibular tooth surface, so that they coincide with the assumed longitudinal axis of the tooth. Bond polymerization in the area of each tooth is performed to temporarily fix the wire guides to the tooth surface. An orthopantomogram is performed, and the accuracy of teeth longitudinal axes determination is evaluated based thereon. If the fixed wire guides and teeth longitudinal axes do not coincide, the angle of deflection of the wire guide from the tooth longitudinal axis is measured, the angle of deflection between the wire guide and the tooth longitudinal axis is measured, and the distance between the sides of the deflection angle is measured in millimeters in the region of the tooth neck in accordance with the size of the tooth crown. Corrections are made to fix the wire guides, moving their gingival part to the required value. After that, impressions are taken from the patient's jaws and diagnostic plaster models are produced that have precise orientations of the wire guides to determine the teeth longitudinal axes. A platform is prepared on the obtained plaster model for brackets fixation, cutting off guide prints in the area of the crown middle and keeping them in the area of the gingival and occlusal edges to guide the direction of the teeth longitudinal axis. Then brackets are fixed to the plaster models, so that the bracket longitudinal axis coincides with the direction of the wire guides prints. After that, mouthguards are made with brackets located therein, which are fixed in the oral cavity according to the standard procedure.

EFFECT: due to precise determination of the tooth longitudinal axis, the method, allows to reduce the number of errors in bracket system fixation, the number of position adjustments of brackets and various compensatory bends at the final stages of treatment.

SUBSTANCE: invention relates to medicine, namely to dentistry and is intended for correction of detected by early diagnostics temporomandibular joint (TMJ) dysfunctions. Anthropometry of face is carried out in order to determine displacement of lower jaw and measure the height of lower third part of face. Displacement of lower jaw is determined in sagittal, transversal and distal directions. In order to determine distal displacement of lower jaw Eshler-Bittner test is applied. To determine lateral displacements occlusography is carried out in habitual occlusion, results are obtained by computer program T-Scan. Orthopantomography is performed and value of joint spaces is determined. If secondary displacements of lower law in sagittal and/or transversal and/or distal directions are determined, joint spaces of various value on orthopantomogram and change of height of lower third part of face are present, dysfunction of TMJ is diagnosed. Lower jaw is installed in neutral state in central occlusion, mouthguard with bite sites for fixation of lower jaw in said position is made. Occlusography is repeated in central occlusion together with mouthguard, difference of initial and blocking contacts is determined and in case if contact is advanced, selective lapping is carried out. Conclusion about elimination of dysfunction is made on the basis of patient's subjective sensations, anthropometric data and holding of lower jaw in position without displacement in sagittal and transversal planes. Final correction of mouthguard is performed in central occlusion under control of OPTG with central position of TMJ head in glenoid fossa, after which mouthguard from silicon is replaced with plastic. Myotherapy is administered and orthodontic treatment and/or dental prosthetics is performed after adaptation in accordance with indications.

EFFECT: method makes it possible to detect and prevent TMJ diseases before development of expressed pathologic joint symptoms due to correction of TMJ dysfunction before clinical symptoms of joint pathology develop.

SUBSTANCE: invention relates to field of medicine, namely to orthodontic dentistry, and is intended for retaining stable result after performed orthodontic treatment. Non-detachable retainers are fixed on upper and lower dentitions after passive fitting. Non-detachable bite sites from composite material, imitating expressed incisive papillae are made on palate surface of incisors 1.1 and 2.1. Retainer on lower dentition is fixed on the segment from 4.4 to 3.4 teeth. Length of retainer on upper dentition depends on initial anomaly of teeth position and method of treatment. In case of initial vestibular position of canines and treatment of deep overbite without extraction of teeth 1.4 and 2.4 retainer is fixed from 1.3 to 2.3 teeth. In case of extraction of teeth 1.4 and 2.4 retainer is continued to 1.5 and 2.5 teeth. In case of absence of vestibular position of canines and treatment of deep overbite without extraction of 1.4 and 2.4 teeth retainer is installed from 1.2 to 2.2 teeth.
