The invention relates to medicine, in particular to orthodontic dentistry, and can be used to hold a stable result after orthodontic treatment vertical malocclusion in adult patients with deep cutting occlusion and deep cutting of disocclusion, which are United by the term - deep tool overlap (SRC).

When deep cutting overlap observed functional impairment, namely reduced chewing efficiency, often injured mucosa in contact with the cutting edges of the cutters, which causes an overload of periodontal and contributes to the onset and/or progression of periodontal disease.

To obtain long-term results of treatment of deep cutting overlapping difficult in connection with the etiology of its formation, a variety of morphological and functional disorders of the maxillofacial region.

Criteria completion of the orthodontic treatment of deep miracolosa overlap is to achieve optimal occlusion from the point of view of not only aesthetics, but function. At the end of orthodontic treatment need time to reorganize the gingival and periodontal tissues, which had the effect of orthodontic tooth movement. Therefore, after the removal of the device, the teeth may have Itsa in an unstable position, so the pressure from the soft tissues creates a constant threat of relapse.

Morphological abnormalities in the maxillofacial region are eliminated faster than functional, and therefore it is necessary to ensure the sustainability of the achieved results to the full normalization of the function of the masticatory and facial muscles. In this regard, after the treatment requires a reliable retention of the obtained cutting overlap, which will withstand the usual effects of soft tissue and articulation.

Closest to the proposed is a popular method of retention of the orthodontic treatment of hydraulic fracturing, according to which the lower and upper teeth fixed removable retainers made of neproportionala rod wire, which is bent in the form of the dental arch from the lingual or palatal surfaces of the teeth of the lower and upper range, respectively, and fixed to a corresponding set of teeth by bonding the adhesive after passive prepisovanie and subsequent etching, with the retainer on the lower dentition fix for 3.3. 4.3. tooth, and at the upper teeth retainer is fixed for 1.3. to-2.3. or 1.2. to 2.2. the tooth. In addition, the upper jaw is fixed removable nakonechnyy plate (Cardboard E.A., Lindenholt ZH.A., PE is blue PS The retention and relapse, Moscow, 2006; Proffit WR Modern orthodontics, Moscow: Medpress-inform, 2006, 473, 523).

The disadvantage of this method consists in the following. The fixation of the retainer on the lower dentition for 3.3. 4.3. tooth does not exclude the possibility of the intrusion of the premolars and the extrusion of anterior teeth of the lower jaw. When fixing the retainer to the upper teeth for for 1.3. to-2.3 tooth or 1.2. to 2.2. the tooth does not take into account the initial anomaly of the dentition and the method of treatment that can lead to relapse.

The use of removable Nakonechny plate does not provide continuous monitoring of vertical overlap and prevent slippage of the lower incisors and their extrusion because of the possibility of occasional use removable Nakonechny plate ("forgot", "broke", "once") generates a recurrence of the pathology of hydraulic fracturing. As a result, the use of removable Nakonechny plates leads to a dependence of the retention of the subjective factor, because it puts the result of retention in dependence on the patient's responsibility.

All of the above reduces the effectiveness of retention. In addition, the presence of removable devices uncomfortable for an adult as it closes (is) area of the sky that causes discomfort and leads to disruption of diction. This reduces fiziologicr is any known method.

The claimed invention solves the problem of creating a method of retention of the orthodontic treatment of deep cutting overlap, which ensures the achievement of the technical result, which involves improving the efficiency of retention by providing opportunities simultaneous control of tooth position and occlusion in a vertical plane through a fixed retention, as well as in increasing the physiology of the method.

The essence of the claimed invention is that the method of retention of the orthodontic treatment of deep cutting overlap, whereby the upper and lower dentition after passive prepisovanie fixed removable retainers made of neproportionala rod wire, which is bent in the form of the dental arch from the lingual or palatal surfaces of the teeth of the lower and upper range, respectively, and fixed to a corresponding set of teeth by bonding with adhesive, the newis that the retainer on the lower dentition fix for 4.4. to 3.4. teeth, and the length of the retainer on the upper tooth row is selected depending on the anomalies of tooth position of the dentition, which was originally, and treatment method, in addition, on the palatal surfaces of the incisors 1.1. 2.1. perform fixed Nacu the intramural fields, simulating expressed cutting bumps, so as not to inflate the occlusion and to keep a tight fissure-occupied and cutting contacts. However: if you originally had vestibular position of teeth and the treatment of deep cutting overlapping performed without the removal of teeth 1.4. and 2.4., the retainer is fixed from to 2.3 tooth; if the treatment of deep cutting overlapping performed extractions 1.4. and 2.4., the retainer extend to 1.5. and 2.5 teeth; in the absence of vestibular position of the canines and in the treatment of deep cutting slabs without extractions 1.4. and 2.4. retainer set from 1.2. to 2.2 tooth. In addition, nakonechnyi pad made of a composite material during installation of the retainer or correct remaining after treatment nakonechnyi site.

The technical result is achieved in the following way. As mentioned above, the criterion for the end of orthodontic treatment is to achieve optimal occlusion from the point of view of not only aesthetics, but function. At the end of orthodontic treatment need time to reorganize the gingival and periodontal tissues, which had the effect of orthodontic tooth movement. Therefore, after the removal of the device, the teeth may be in an unstable position because the pressure from the soft tissues creates a permanent ASO is the possibility of relapse. In addition, morphological abnormalities in the maxillofacial region are eliminated faster than functional, and therefore it is necessary to ensure the sustainability of the achieved results to the full normalization of the function of the masticatory and facial muscles. In this regard, after the treatment requires a reliable retention of the obtained cutting overlap, which will withstand the usual effects of soft tissue and articulation.

After the correction of hydraulic fracturing required retention of interalveolar height is observed between the jaws, a permanent control of the vertical overlap of the incisors, that is, opposition to the main pathogenetic mechanisms of development of deep cutting overlap: deepening the sagittal occlusal curve of Spee (Spee), molar intrusion, shortening of the lower dentition and the lengthening of the upper dentition, protrusion, and extrusion of the upper incisors, retrosi and extrusion of the lower incisors, rotation and crowding of the lower incisors, the formation of the three upper tooth row.

Especially unstable after treatment, the intrusion of incisors and extrusion of the molars, which according to D.Brothag, A.Zentner often suffer recurrence.

The features of the invention: "Method of retention of the orthodontic treatment of deep cutting overlap, whereby the upper and lower dentition after passive Priazovye which I fixed with a removable retainers, made of neproportionala rod wire, which is bent in the form of the dental arch from the lingual or palatal surfaces of the teeth of the lower and upper range, respectively, and fixed to a corresponding set of teeth by bonding with adhesive,..." are an integral part of the claimed process and ensure its viability, and consequently, achieve the stated technical result.

In the proposed method retainers fixed on the dentition by gluing the adhesive after passive prepisovanie, which increases the physiology of the claimed method, as it considers the individual characteristics of the patient's jaw. This retainer on the lower dentition fix for 4.4. to 3.4. teeth. As experience has shown, an increase in comparison with the prototype, the length of the retainer on the lower set of teeth to the teeth 4.4. and 3.4. do not allow the formation of intrusions premolars and extrusion of anterior teeth of the lower jaw, which ensures the fixation of treatment results.

Due to the fact that at the upper teeth fixed, non-removable retainer, the length of which depends on the anomalies of the dentition, which was originally, and method of treatment, taking into account specific features of the dentition of the patient before treatment and features used in the orthodontic appliances. This allows you to choose the optimal length of the retainer, while minimizing the number prepariruetsya teeth for the installation of the retainers, which increases the physiology of the claimed method. In addition, it provides a reliable position control of all teeth, previously shaped anomaly of the dentition and accepted physiological position upon removal of the anomaly.

As a result of experience obtained from the following options length of a non-removable retainer on the upper dentition:

1) in the presence of vestibular position of teeth and the treatment without extractions 1.4. and 2.4. the retainer is fixed to the 1.3. up to 2.3 tooth. In this case, provide the possibility of controlling the position of the canines;

2) when treatment with extractions 1.4. and 2.4 retainer extend to 1.5. and 2.5 teeth. In this case, provide the ability to control the disclosure of three;

3) in the absence of vestibular position of the canines and in the treatment of deep cutting slabs without extractions 1.4. and 2.4. retainer set from 1.2. to 2.2 tooth. In this case, control only the right incisor position reached as a result of treatment.

For control of vertical overlap and prevent slippage of the lower incisors and their extrusion using a fixed nakonechnyi sites that perform on the palatal surfaces of the incisors 1.1. 2.1. top subrogated. Fixed nakonechnyi pad is formed using a composite material and silicone molds for making Nakonechnyj braces (sites), for example, from a set of Mini mold starter kit firm Ortho technology, or amend existing nakonechnyi sites that remained after treatment, simulating expressed tool tubercles. This nakonechnyi pad is formed in such a way as not to inflate the occlusion and to keep a tight fissure-papulose contacts to ensure positive outcomes after treatment, and also ensures that the physiology of the claimed method. In addition, since the fixed nakonechnyi sites perform on the palatal surfaces of the incisors 1.1. 2.1. the upper dentition, the sky remains free. As a result, disappears associated with this discomfort, there is no violation of diction. This increases the physiology of the claimed method. The choice of material for the manufacture Nakonechnyj sites due to the fact that it is made of a composite nakonechnyi sites have an advantage over metal in that their size and shape can be adjusted individually for each patient, achieving the desired result, which also increases the physiology of the claimed method.

From the above it follows that the claimed method proposes the use without removal the retention, simply install on both jaws of the patient population of fixed retainers: retainers on the upper and lower jaw and fixed Nakonechna Playground on the palatal surfaces of the incisors 1.1. 2.1. It takes into account the need for lifelong retention after treatment of deep cutting overlap and provides the possibility of its implementation. While the claimed method allows through a non-removable retention to provide simultaneous control of tooth position and occlusion in the vertical plane. Moreover, due to the use of the proposed method of performing non-removable retention, the proposed method operates around the clock, with the result of retention does not depend on subjective factors that, together, provides effective retention. The use of fixed retainers in conjunction with fixed Nakonechny platform reduces discomfort, relieve the patient of reminders on the use of the apparatus does not depend on cooperation with the patient, purposefully and constantly affected by pathogenic and etiological components of the development of pathology and provides long-term retention, not only preventing the crowding after correction of rotations, but keeping occlusion in the vertical plane. This avoids the possible causes of relapse, POSCO is ICU method takes into account the anomalies of tooth position of the dentition, which was originally, and also considers the treatment of this anomaly. As a result, maintaining the teeth in their new position for quite a long period of time allows the body to adapt to a new situation dentoalveolar apparatus that guarantees the stability of treatment results.

As experience has shown, the claimed method ensures that the optimal occlusion achieved after orthodontic treatment of deep cutting overlap, namely: the preservation of the normal cutting overlap (up to 3 mm) with Reztsova contact the upper and lower incisors, with possible values miracolosa angle within 1255, with tight fissure-ugarkovic contacts, flattened or direct occlusal line (up to 2 mm), cutting and cleavage doing occlusion.

Thus, from the above it follows that the claimed method of retention of the orthodontic treatment of deep cutting overlap in the implementation ensures the achievement of the technical result, which involves improving the efficiency of retention by providing opportunities simultaneous control of tooth position and occlusion in the vertical plane through the use of fixed retention, as well as to improve physiology of the method.

The method is performed as follows. On the upper and lower dentition after passive prepisovanie fixed removable retainers made of neproportionala rod wire, which is bent in the form of the dental arch from the lingual or palatal surfaces of the teeth of the lower and upper range, respectively. Retainers fixed by gluing the adhesive. This retainer on the lower dentition fix for 4.4. to 3.4. teeth. The length of the retainer on the upper tooth row is selected depending on the anomalies of tooth position of the dentition, which was originally, and treatment. In addition, not what Noah surfaces of incisors 1.1. 2.1. perform fixed nakonechnyi ground, imitating expressed cutting bumps, so as not to inflate the occlusion and to keep a tight fissure-occupied and cutting contacts. In addition, if the abnormality of the teeth of the dentition was expressed in the presence of vestibular position of teeth and the treatment of deep cutting overlapping performed without removal of the teeth, the retainer is fixed to the 1.3. up to 2.3 tooth; if the treatment of deep cutting overlapping performed extractions 1.4. and 2.4., the retainer extend to 1.5. and 2.5 teeth; in the absence of vestibular position of the canines and in the treatment of deep cutting slabs without extractions 1.4. and 2.4. retainer set from 1.2. to 2.2 tooth. This nakonechnyi sites perform or of composite material, or adjust remaining after treatment nakonechnyi site.

In the examples perform the inventive method after the treatment was removed from the corrected teeth apparatus with the help of tongs for removing the braces, rings (if necessary), removed the adhesive using a dedicated hog.

Then perform complex professional hygiene of the oral cavity without covering fluoride preparations.

Next passively prepassivate wire on the lower jaw for 4.4. to 3.4. teeth and the upper teeth of different length, Kotor is dependent on the anomalies of the teeth and dentition, originally, and the method of their treatment.

Options length of a non-removable retainer on the upper dentition:

1) in the presence of vestibular position of teeth and the treatment without extractions 1.4. and 2.4. the retainer is fixed to the 1.3. up to 2.3 tooth. In this case, provide the possibility of controlling the position of fangs.

2) when treatment with extractions 1.4. and 2.4 retainer extend to 1.5. and 2.5 teeth. In this case, provide the ability to control the disclosure of three.

3) in the absence of vestibular position of the canines and in the treatment of deep cutting slabs without extractions 1.4. and 2.4. retainer set from 1.2. to 2.2 tooth. In this case, control only the right incisor position reached as a result of treatment.

The thickness of the retainer and its section on the upper and lower jaws are different. To prevent rotation, usually used on the lower jaw Respond.0175 or Tripleflex.0,175 (when expressed initially crowding of the teeth on the upper jaw - Respond.0195,.0215, Tripleflex.0.0175,.0195 or D-Rect.0175*.0125 (for torque control incisors).

After drying the teeth were treated enamel in the most flat part of the palatal (lingual) surfaces of the crowns of incisors and canines (for the most snug fit of the retainer) 37% gel phosphoric acid for 30 seconds. Then washed for 1 minute and dried processed zu the s.

Then were treated with an adhesive (for example, the adhesive OrthoSolo) potraviny the surface of the teeth in a thin layer with the inflating air from the gun, polymerizable for 20 seconds (or instructions to the material) light-curing lamp.

After this was done fixing passively priazovskogo retainer flowable composite material (Filtek Ultimate Flowable Restorative, 3m ESPE) using orthodontic scaler. As a rule, in fissures 3.4. and 4.4. retainer recorded with the use of invasive techniques (i.e. preliminary preparation fissures spherical boron at a distance of about 2 mm to a depth of about 0.5 mm). Increase the length of the retainer to the teeth 3.4 I..4 provides control intrusion premolars and extrusion of anterior teeth of the lower jaw.

To control vertical overlap and prevent slippage of the lower incisors and extrusion on the palatal surface 1.1. 2.1. using the same composite and silicone molds for making Nakonechnyj sites from a set of Mini mold starter kit company Ortho - technology installed or adjust existing nakonechnyi ground, imitating expressed tool tubercles, but in such a way as not to inflate the occlusion and to keep a tight fissure-papulose contacts. The polymerization of the material was performed using curing lights is within 20 seconds on each tooth.

Made of composite nakonechnyi sites have an advantage over metal in that their size and shape can be adjusted as needed.

Using articulation paper "Bausch" monitored and presledovanie of super contacts in case (correction of occlusal contacts). Final polishing was performed with a paper disks of different abrasiveness, then silicone heads. After which he was assigned fluoridation of enamel.

Example 1. The example explained in figure 1 figure 5.

Patient B. O., 23 years has made a complaint to the incorrect position of teeth, "retraction" of the tooth 1.1., aesthetic dissatisfaction, crackle in the parotid region with a wide mouth opening with 2 sides.

After clinical and radiological examination diagnosed-dental: distal occlusion, deep traumatic Burin disocclusion, narrowing of the upper dentition, retrose upper incisors, extrusion of the lower incisors, the close position of the teeth of the lower jaw, the rotation of the teeth;

musculoskeletal: skeletal class 2, retopologize both jaws, normatively, BINETRUY incisors, increased miracolosa angle, reducing nasolabial angle.

Orthodontic treatment is carried out with full fixed appliances in combination with a removable functional apparatus, which was then replaced by a bore is mnie nakonechnyi site. The duration of treatment was 24 months.

After the treatment equipment was removed. According to the claimed method installed removable retainers on the lower jaw for 4.4. to 3.4. teeth. As before treatment had vestibular position of teeth and the treatment is performed without removing teeth 1.4. and 2.4., the upper jaw was set, non-removable retainer from 1.3. up to 2.3 tooth. To perform Nakonechnyj sites available used after treatment on teeth 1.1. and 2.1., which were corrected with imitation expressed on compound curves, so as not to inflate the occlusion and to keep a tight fissure-occupied and cutting contacts.

The patient was observed in the retention period at intervals of 1 every 6 months. Now, 2 years after the end of treatment the result is stable in all planes, which allows to conclude that the proposed method of retention not only keeps the teeth in the new position, but also control the change of vertical that need to consolidate the results of treatment of deep cutting overlap.

Example 2. Example of installation on the teeth of the upper jaw fixed retainers and perform fixed Nakonechnyj sites on the palatal surfaces of the teeth 1.1. 2.1. in the treatment with extractions 1.4. and 2.4 is shown in Fig.6.

Two-leaf kappa // 2327434

FIELD: medicine; stomatology.

SUBSTANCE: kappa applied for detection of parodentium and jaw bone tissute state is made of non-radiopaque flexible plastics and contain measuring element inside. Kappa is monolithic two-leaf isolated between dentures within first antagonistic molars, filled with plastics along isolation lengthwise. Measuring element is designed as graduated orthodontic wire and installed within kappa body in first antagonistic molars area. Within anterior teeth group inside of kappa body there is a cavity for attachment or strip rigidly mounted to orthopantomograph. Invention enables to provide accurate detection of bone tissues within first and subsequent X-ray examination (orthopantomogram, panoramic radiograph) with equally fixed position of jaws, increased efficiency of oral therapy.

EFFECT: improved objective diagnostics of facial bone state associated with oral therapy in dynamics under orthopantomogram results by means of simple device.

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.

EFFECT: method makes it possible to increase retention efficiency due to possibility of simultaneous control of teeth position and occlusion in vertical plane by means of non-detachable retention.

SUBSTANCE: removable individual replaceable myogymnastic element (RIRME) representing an individually curved orthodontic wire having a many-sided bead is fixed for 2 hours a day and for a period of logopaedic treatment into closed canals of the palatal plate of the removable appliance. A patient moves his/her tongue: touches the bead and displaces it in different directions along the wire trajectory. As the range of motions increases, the RIRME is changed by a new one with the complex trajectory and a smaller bead. The lessons are continued until the tongue functions are recovered completely.

EFFECT: method enables shortening the rehabilitation period that is ensured by orthodontic treatment in a combination with functional correction and use of the myogymnastic element that is complicated in the process of treatment.
