Twin Block device: features, indications, principle of operation, results

11335

Bite pathologies bring enough trouble to all their “owners.” They can not only deprive a person of an attractive smile, but also cause psychological problems.

Very often, such a complication is speech defects, which are perceived by a person as especially painful.

Some suffer less, others more, but, in any case, regardless of the patient’s age (and bite deviations are considered to be a diagnosis), such anomalies require mandatory treatment.

One of the methods to solve the problem is special devices. Twin Block is a modern orthodontic design for bite correction. This will be discussed in this article.

Indications

The use of the Twin Block device is indicated in the following cases:

incorrect angle of inclination of individual fragments of the jaw row of one of the jaws;
inadequate closure of teeth, especially the frontal part, as well as the presence of sagittal spaces between organs;
pronounced overlap of one incisor with another;
in situations where the bone organs located in the central part of the jaws are in poor or no contact with each other.

Contraindications

When it comes to contraindications, experts point to their indirect nature.

So, in essence, the patient’s age group does not exclude the use of this correction method, however, the result will be weak or absent altogether.

The greatest effectiveness of the device was noted in adolescence.

The design should be used with particular caution if the patient suffers from gum disease or other dental diagnoses.

In this case, the affected area of the oral cavity is first treated, and then correction is prescribed.

Design features

The standard design of the device consists of the following elements:

base plates are the basis of the product, and it is they who undertake all the work to eliminate bite deviations. They are manufactured individually, taking into account the anatomical structure of the maxillofacial apparatus and the characteristics of the clinical picture of the pathology;
Leveling arcs are metal devices that set the plates in motion. They provide the necessary tension force, the level of which is adjusted as the treatment progresses;
screws - perform a fastening function and control the degree of compression of the plates. The specialist manually adjusts their location several times during the course of treatment.

It is also possible to develop and manufacture atypical Twin Block systems, taking into account individual characteristics and the goals set for the device.

Tooth-supported device MSE (Maxillary Skeletal Expander)

A non-removable structure supported by teeth will allow you to quickly expand the upper palate and eliminate anomalies in the structure of the dental system. The expander consists of four orthodontic rings attached to the molars or premolars, a palatal bar and an expansion screw. The retention period ranges from three to six months. Among the indications:

respiratory dysfunction;
congenital defects of facial bones;
lack of space for teeth in the upper jaw arch;
open bite.

The treatment is an excellent alternative to surgical expansion of the jaw and shows high effectiveness in children. In combination with braces it is successful in adult patients.

How the device works

The principle of equalizing bite deviations is based on mechanical pressure on the necessary zones of the jaw row.
In this case, the pressure must be constant and a certain force load. This is provided by screw elements and leveling arches, and the direction is set by a specialist - an orthodontist.

Over time, teeth begin to change their growth trajectory, gradually taking on the correct position.

Treatment can last for many months with periodic adjustment of the tension of the arcs and correction of the screw mechanism in order to achieve the most precise impact on the desired areas.

Advantages

If we compare the treatment process with this device and analog models, Twin Box is in a more advantageous position - a positive result comes much faster.

The main advantages of the device are highlighted:

the ability to use it constantly without removing it while eating;
a minimum period of physiological and psychological adaptation, during which the functionality of the tongue, cheeks and lips will remain fully intact;
the transition after wearing structures to using non-removable devices is much easier than if they were installed initially;
During the correction process, third-party interference in the work of the dentofacial organs is minimal.

Benefits of an orthodontic appliance

Twinblock is an orthodontic device that is in great demand. This comes with a number of advantages, including:

high aesthetics. The design is equipped with thin vestibular arches (in some cases, the arches are completely absent). She is practically invisible to others;
comfort and ease of wearing. The design can be used constantly, without removing it while eating food. In addition, chewing load enhances the effect of therapy;
minimal third-party interference in the work of the dental organs;
accelerated physiological and psychological adaptation by maintaining normal mobility of soft tissues (cheeks, lips and tongue). After a few days, a person can chew food without problems, without experiencing discomfort or pain;
relatively quick achievement of positive results;
easier transition to non-removable orthopedic structures.

Features of wearing and caring for the twin block device

During the first days, during which you continue to get used to the device, you are allowed to remove it while eating. However, this should not be done in the future, since chewing processes enhance efficiency. Twin block does not interfere with lateral and vertical movements of the jaw. When you first start wearing the device, you may experience slight discomfort and increased salivation. Over time they will go away on their own.

In order for the results to meet expectations, the orthodontic appliance should be used regularly. It is recommended not to stop using it even for a short period. Due to the special design, which reduces the level of discomfort during therapy, a person gets used to it very quickly. To avoid damage to the structure, it is recommended to remove it only before engaging in contact sports (wrestling, boxing).

Caring for orthodontic structures is not difficult. When brushing your teeth, it is important to pay attention to it, thoroughly cleaning it with a toothbrush. It is recommended to irrigate the oral cavity once a day with a fluoride solution. It is important to use a special hard case for storage. In the rare cases where it is not in the oral cavity, it needs to be properly stored. If the device is damaged, it is important to contact your doctor immediately.

In some situations, to consolidate the results obtained from the use of a twin block, the help of a non-removable orthodontic structure – braces – may be required. The duration of their wearing is determined individually. On average, it takes about 6 months.

Kinds

Twin blocks, depending on their design features, are classified according to class and subclass affiliation according to the Engle system:

Second class 1 subclass therapy is carried out for pronounced incisal overlap and arc narrowing to the desired position.
For this purpose, the device is mounted so that each time a control inspection is carried out by a specialist, the screw is turned a little.
So, gradually, the dental arch expands, regulating the positions of incorrectly developing organs.
The second class, subclass 2 , is justified when it is necessary to eliminate the pathology of too short teeth in the lower jaw or excessive crowding of the frontal organs. In such situations, the arc tension is adjusted quite often, usually once every 4-5 days.
Class 3 is acceptable for correcting the pathology of crowding of dental fragments with shortened growth anomalies. The best results are obtained when work is required on a vertical plane.

Treatment with braces

After correcting the position of the lower jaw, metal Victory braces (3M) were installed. The installation of braces is carried out in two stages - first on the upper jaw, and after two weeks - on the lower jaw. This makes it easier to get used to braces, and the process of installing braces is quite labor-intensive and time-consuming. To maintain the required bite height, overlays, which are made of the same material as fillings, are installed on the distal chewing lower teeth. As treatment progresses, the overlays are gradually removed.

Braces are installed on the upper jaw:

Braces are installed on the lower jaw:

One month after installing braces:

Three months from the start of treatment with braces:

Situation six months after fixing braces:

One year from the start of treatment with braces:

Treatment with braces took 13 months. The teenager visited the orthodontist once a month. During visits, the doctor changed the arches, introduced additional elements, and monitored the treatment process.

With the help of braces, gaps between teeth are eliminated, teeth are aligned, and the upper and lower teeth are properly connected.

Preparation

Any therapeutic manipulations require careful preliminary preparation; the success of further treatment of the disease largely depends on this.

Clinical stage

The initial stage in correcting malocclusions is an initial visit to the dentist, when the oral cavity undergoes a thorough examination.

Based on the results of the examination, a final diagnosis is made and a plan for eliminating a particular problem is developed.

This stage is called clinical. After obtaining an objective picture of the condition of the oral cavity and determining the degree of development of the pathology, anatomical templates are made - impressions .

Working copies are made, on the basis of which wax models of the future structure are cast.

Laboratory stage

At the laboratory stage, according to the developed scheme for the course of therapy and the specifics of the anatomical structure of the oral cavity, the production of a medical device is carried out.

First, a working version is made, and after trying on and adjusting the design, a permanent device is made that will be installed on the patient.

The installation procedure itself requires only one visit and takes no more than 10-15 minutes, including preparatory procedures.

After installing the Twinblock, the doctor gives additional advice and recommendations on caring for the structures and the specifics of the treatment.

The purposes for which the device is used and its design features are discussed in the video.

How to correct a bite using Twin Block: treatment stages

What to do if you are not sure that after changing teeth the child’s bite is formed correctly? The first step is to come for a consultation with an orthodontist.

Then proceed according to the following scheme:

The doctor carefully examines the condition of the dental system and determines the type of abnormal bite.
If Twin Block is indicated, the dentist takes impressions of both jaws.
In a dental laboratory, a wax model of the apparatus is made from impressions, and the location of the arches is modeled on it.
After fitting, the wax base is replaced with plastic plates.
The dentist installs the finished Twin Block device for the patient, adjusts the design if necessary, and fixes it on the jaws. The installation procedure lasts 20 minutes.
The patient comes back a week later for adjustment of the device. Typically, adjusting the plates and arches takes 10–15 minutes.

How often you need to go for correction depends on the type of structure: for example, if an apparatus is used to eliminate crowding of teeth, the blocks need to be adjusted once every 4-5 days, in other cases - less often. The schedule of further visits will be drawn up by the orthodontist.

You need results - follow the rules

There are no major difficulties in using Twin Block for the patient; the main thing is to follow the orthodontist’s recommendations regarding how to wear the plates and care for the device.

How to use twin blocks:

Recommendations for wearing and care

The positive dynamics from the use of Twin Block depends not only on the professionalism of the doctor, but also on the efforts of the patient, and his compliance with the necessary requirements for wearing and caring for the device.

The following recommendations must be strictly adhered to:

The product must be used constantly. Do not allow yourself to remove the device even for a short period of time;
remove the system only when it is necessary to brush your teeth, or during sports training;
if there is some discomfort, increased secretion of salivary fluid, it is important to understand that this is a short-term phenomenon that will disappear spontaneously;
In order for positive dynamics to manifest themselves as soon as possible, you should try to stay in a state of closed jaws as much as possible. If you do this regularly, you will subsequently be able to talk in this position;
the structure must be cleaned regularly according to the same principle as standard treatment of the oral cavity;
store the product in a special container;
In order for the result to be permanent, after treatment with Twin Block, it is advisable to undergo a course of therapy using braces;
It is advisable to irrigate the oral cavity once a day with a fluoride solution.

Difficulties of treatment using the Twin block device

At the beginning of treatment, using the device causes inconvenience to the patient. At the same time, in order to get the planned result, you need to wear it at least 20 hours a day (in fact, it is recommended to remove the device only when eating and brushing your teeth).

The device changes diction, so the child may have difficulties in school. To correct diction, it is recommended to read poetry and tongue twisters aloud.

A contraindication to treatment with a Twin block is an allergic reaction to the plastic from which it is made.

In general, this device may not be suitable for all patients, so the details of treatment are discussed in advance with parents and an informed decision is made together with the doctor.

However, if the difficulties are surmountable, the result is worth the inconvenience.

Orthodontic treatment with braces, at a later age, can correct the position of the teeth, but not the position of the lower jaw, which means the profile will not change: the chin will remain behind and the mental fold will be noticeable.

Effect of use

The greatest effect from using the device is achieved with regular use and compliance with all doctor’s recommendations.

In this case, it is possible to correct pronounced malocclusions, correct the correct growth of organs, and also achieve complete closure of the jaws.

It is best to use structures when correcting deviations in children’s bite.

Price

If we talk about the cost of such treatment, it is quite difficult to say for sure how much it will cost. This depends on the status of the medical institution, the design features of the device, and the degree of neglect of the pathology.

On average, the price for Twin Block correction will be from 30 to 60 thousand rubles.

Of course, this is expensive, but eliminating the troubles that persistent malocclusion can cause will cost much more. And no one canceled the aesthetic side.

How often should you visit the orthodontist during treatment and then what?

You need to come to the clinic for device correction on average once every 6 weeks. The correction consists of freeing up space in the plates for the eruption of permanent teeth.

After completing treatment, it is recommended to visit the orthodontist for the first time after six months.

Whether the patient will need orthodontic treatment in the future depends on the stability of the result obtained, which is influenced by many factors, one of which is a possible growth spurt in the child.
