Multi-loop arch – aesthetic and individual orthodontic treatment

4172

Modern methods of correcting bite defects are technologies of a completely new, innovative format.

With them, not only the course of treatment is significantly shortened, but the process of wearing the structures itself is no longer associated with discomfort. And their effectiveness is many times higher than standard braces.

Design features. Action

The standard device with a straight arch does not take into account the anatomical specifics of the teeth of a particular person, and in a number of clinical cases it is simply impossible to put the jaw row in a normal position.

MDP has broad capabilities in terms of individual correction of the direction of growth of each individual fragment of the row, leveling the abnormal position of the teeth.

Horizontal loops easily move the organ simultaneously in three projections. This is the main difference from the correction method using a straight arch, when a specialist fixes braces on the teeth and installs an arch between them.

As treatment progresses, designs change from thin products to thicker counterparts. If necessary, the number of arcs can vary, but their shape will only be straight.

The MTD technique consists of only two tension systems, in which one is standard, and the second has several loops. The design is formed by the orthodontist independently, based on the patient’s diagnosis.

The arc remains in the cavity until the end of the correction, while the doctor simply periodically bends the loops as the organ changes its position. This technology works much faster, and the course of treatment on average is reduced by 6–7 months.

The fundamental difference between these two methods is the preservation of four organs - premolars, while traditional bite correction almost always involves their removal.

At this address https://orto-info.ru/sistemyi-vyiravnivaniya-zubov/breketyi/dlya-podrostka-skolko-stoyat-i-tsena-lecheniya.html we will discuss which braces are best for a teenager.

Advantages and disadvantages of the meaw technique

The advantages of a multi-loop arch over classical types of brace systems for the correction of dentoalveolar anomalies are:

Possibility of use in the most difficult cases.
Reduction of treatment time by 6-7 months compared to using a straight arc.
Ensuring the displacement of each dental unit along its own trajectory in three planes, which a straight arch cannot provide.
Adjustment and control of tooth movement by changing the pressure force of orthodontic equipment.
Significantly lower need for premolar extractions.
The ability to straighten lateral teeth by activating the posterior portions of the IVD.
High efficiency and stable correction results. When using the MEAW technique, the use of retention devices is not necessary.

Among the disadvantages of the Sadao Sato system, orthodontists note the complexity of manufacturing and maintaining the structure, as well as its obvious unaesthetics, even when using transparent braces and lingual systems. However, when the MEAW technique serves as the only alternative to surgical intervention, these disadvantages recede into the background.

Indications

Indications for correction using IVD are the following clinical anomalies:

Class III occlusion with both low and high angles;
open bite of the first and second degree;
deep vertical ceiling class 2;
mandibular deviation;
crowding of the dentition or its fragments;
TMJ dysfunction, regardless of the side and degree of displacement;
increase in the height of the upper jaw;
increasing the vertical gap with pronounced pathological steepness of the molars;
eliminating too much forward rotation of the mandible.

Why is it important to correct your bite?

The correctness of the bite determines not only how a person’s smile will look, but also the state of his health as a whole, since everything in the body is interconnected.
Constant or systematic headaches, as well as hearing loss, can often be a consequence of malocclusion. Often in people with dental anomalies, in addition to headaches and hearing problems, spinal curvature can be observed. Crunching, clicking and painful sensations when yawning or simply opening the mouth can be a consequence of bite pathologies. It is statistically known that people with correct occlusion live on average 20-25% longer. This may be due, for example, to the fact that in some pathologies the lower jaw moves slightly back. As a result, the airway narrows and there is a deficiency of oxygen reaching the heart.

Advantages

The method of correcting malocclusion pathologies discussed in the article has a number of advantages, which have been repeatedly confirmed by its practical application:

load reduction - minimizing the pressing force is carried out by exerting a weak but continuous orthodontic force on the jaw row;
optimization of movement of control of each individual organ - in some cases it is possible to achieve displacement of not only fragments of teeth, but also the entire jaw;
facilitating the process of straightening and introducing teeth that are abnormally protruding from the normal position. At the same time, the integrity of the tissues is preserved, and their abrasion in the joint area is minimized;
reconstruction of dental closure is achieved at any stage of deviation of the occlusal plane;
shortening the treatment period by accelerating the period of corrective force;
stable positive dynamics are achieved due to prolonged and softer pressure of the structure.

In addition to the listed advantages, the design discussed in this article has an additional advantage.

It consists in the absence of the need to use orthodontic implanting devices or multiplates, as well as other analog devices, without which correction in a standard way is not possible.

General overview

The development of the concept began at the end of the last century, and took into account all the negative aspects associated with the use of wire elements in bite correction. Sadao Sato studied the features of the anatomical structure of the facial contour, and compared the results obtained with indicators of the functionality of the TMJ, applying to the results obtained auxiliary factors that influence the development of the dentition. The result of the research was the emergence of a new technology involving the use of elements with horizontal hinges, thanks to which it became possible to control the displacement of each individual unit, shortened the duration of correction, and also reduced the likelihood of repeated displacement of teeth to their original position during the retention period.

Flaws

The main, and perhaps the only drawback of a multi-loop wire arch is its unaesthetic quality - the product is too noticeable and not very attractive in appearance. This minus is more than compensated by its high efficiency.

There is also a unique opportunity to avoid surgical intervention during the treatment process, even in the most complex pathologies and advanced clinical cases.

It is worth noting that positive dynamics, a pronounced result and its lasting effect are achieved only in the case of cooperation between the patient and the specialist, based on the patience and mutual understanding of both.

This does not always happen, and a negative result is often attributed not to the imperfections and disadvantages of the system, but rather to a human and moral factor that has nothing to do with the functionality of the MTD.

How to install a multi-loop arch

Before installing the arch, the orthodontist examines the patient’s oral cavity and identifies clinical indications for subsequent treatment. If the patient has a history of caries, tartar or any inflammatory processes, the doctor carries out sanitation of the oral cavity.

After this, using the classical system, braces are made, which are attached to the patient’s teeth. The doctor places a multi-loop arch under the braces. When carrying out corrective measures, the arcs are replaced. At first they are thin, and then they become thicker. After a successful correction, the doctor removes the arch and installs a wire made of biocompatible metal on the inner surface of the dentition.

It is important to know. The MEAW technique helps eliminate the most complex malocclusions without surgery.

At the Saint-Dent Clinic dental clinic in Moscow, patients will be able to receive high-quality orthodontic treatment for a variety of problems associated with malocclusion.

What braces is used with?

The variety of bracket systems compatible with the use of this technology allows you to expand the range of its use and select the optimal model.

The design is selected based on the clinical picture of the pathology, as well as the degree of its neglect, age and financial level of the patient.

The designs fit perfectly:

with vestibular systems fixed on the outer surface of the jaw row;
with lingual ones – they are attached inside, which makes them more invisible;
with self-ligating modern devices that make the correction process more comfortable and less time-consuming.

The material from which braces are made is not particularly important. These can be products made of metal, ceramics, sapphire, or have combined components.

Features of the Multiloop Edgewise ArchWire Design

The MEAW technique involves the use of ligature braces, in which a straight arch connecting the bases is replaced or supplemented with a multi-loop one. Braces can be vestibular or lingual, made of metal, plastic, sapphire and composite polymers.

The material for the arch is a rectangular steel wire with a cross-section of 0.016 x 0.022 or 0.017 x 0.025 inches, and has on each side five horizontal loops located in the spaces between the teeth, starting from the incisors to the molars. The multi-loop arch made it possible to provide a tighter fixation of the system, to influence each dental unit with different forces, tilting and rotating them, and also to regulate the overall displacement of the entire dentition.

The MEAW system is manufactured manually, individually for each patient. The tools for modeling a multi-loop arch are: a calibrated turret arch shaper, distal nippers, dental forceps De La Rossa, Kim, Tweed, Nance.

Installation

The installation procedure takes place in several stages:

Preliminary consultation with a specialist - an anamnesis is drawn up, the most complete information is collected about the stage of the pathology, the absence of contraindications, and the optimal scheme, correction course is selected, and a specific brace system is selected.
Formation of the arch - the procedure is performed by the doctor himself, for which an impression of the jaw row to be corrected is initially made. After the plaster copy is ready, the orthodontist begins to bend the hinges so that the trajectory of the tooth changes according to a given algorithm.
Fastening the arch is carried out in a standard way using special locking latches with a snap mechanism.

What type of brace systems do we install?

Our clinic offers the installation of vestibular type braces. These are classic designs that are fixed to the outer (vestibular) side of the dentition.

They cope with any bite pathologies.
You can get braces at an affordable price.
It’s easier to maintain hygiene and maintain.

Rigid miniature wires or elastic bands - ligatures - are used as fastenings. Therefore, such braces are called ligature. This is the most affordable way to get braces; their price will be the most affordable.

They require careful care and frequent visits to the clinic. However, it is ligature systems that are most effective, so we recommend them for correcting complex defects.

Wearing and care

The basic rule to follow is to be careful with the arches. They can easily be damaged by foods that are too hard, tough, or sticky . Dishes containing such consistencies should be completely excluded from the diet for the entire course of treatment.

In order not to disrupt the integrity or the specified position of the structure, it is necessary to care for and perform hygienic procedures using devices specially designed for this purpose - a single-tuft brush, a special brush and a brush.

It is recommended to use rinses that maintain an optimal acid balance and have an antiseptic effect. They are used after meals and also before going to bed.

In addition, you should try to avoid active sports that can injure the maxillofacial apparatus and lead to damage to the device.

If there is any external deformation of the arch, you should immediately contact the clinic. The doctor will adjust the tension force, and treatment can continue.

Getting Results

If you are one of those who decide to visit an orthodontist, do not forget to follow the recommendations of your doctor. Installation of a bracket system with IVD requires regular visits to the clinic and supervision of a specialist. This is due to the fact that as treatment progresses, the thin arch changes to a thicker one in order to increase the level of effort of this very arch and the impact of bone tissue.

The need for

Based on the data collected during the preliminary examination, the specialist will decide whether intervention makes sense. Most often it is prescribed for patients with an open bite.

Its peculiarity is that after the cast is made and the model is made from plaster, the wire part is placed on the cast. During this process, the doctor manually makes loops that correspond to the impression models of the location of the teeth.

Often, MTD is combined with the straight arc technique. If the doctor insists on combining or the impossibility of using one technique, you should listen to him.

results

Correcting the bite using this technique allows you to achieve positive, stable results: the teeth will be fixed in the required position for 20-30 years.

Long-term practice of orthodontists using MEAW indicates the possibility of correcting even complex malocclusions. IVD also makes it possible to solve problems with jaw displacement.

The advantage of IVD is the possibility of individually influencing each tooth in a row in the required direction, which gives control over the treatment process.

To install or not to install

Definitely yes. Traditional methods - installing braces with an even arch - are in many ways inferior to the considered technique. When using the first method in practice, the result is often far from ideal. And despite the fact that MTD is an order of magnitude more expensive, it guarantees effect.

If an open bite is diagnosed, we recommend that you contact a specialized clinic whose doctors work with IVD (MEAW). You should not postpone a visit to the dentist, since delaying treatment aggravates the development of pathology.

Forecast

As for the timing of correction, as well as the predictability of the pronounced positive dynamics from the treatment provided, everything is individual.

This is explained by the anatomical features of the structure of the organs, the clinical picture, as well as the degree of its neglect, and, of course, the age of the patient. The duration of wearing the structure varies from one to two years.

In most cases, the first results will become noticeable after 4-5 months.

In a state of retention, when the IVD is removed and a thin wire is installed in its place, the organs are still relatively mobile and susceptible to force load.

The time they need to stabilize a positive result is on average about 10 months. Once the retainer is removed, treatment can be considered complete.

Application of MTD

Whether it is necessary to use multi-loop arches in your case, the orthodontist will tell you after the examination. Typically, structures are indicated for patients with an open bite.

First, an impression is made, based on which a plaster model of the patient’s jaw is made. It is necessary to create MEAW according to individual parameters. The doctor places the wire on the impression and manually creates loops that correspond to the location of each tooth. This allows you to target each unit and regulate the force.

The braces are attached with special glue. The structure made by the doctor is secured with locks. It gently guides the teeth into the desired position.

As the teeth shift, the doctor bends the hinges. If it is necessary to create more force, the wire is changed to a thicker one. At a certain stage of treatment, elastics are used - rubber bands between the upper and lower jaws. They should be worn all day, taking off only when brushing your teeth. If you do not follow the recommendations, treatment may be delayed and may not produce results.

In most cases, during correction, the use of multi-loop arches is alternated with straight ones. The doctor knows when to replace the structure. Listen to his recommendations.

Price

The cost of the structure is determined by the number of arcs required for correction and includes:

cast - from 550 rubles
diagnostic copy of the model – from 380 rubles;
arc manufacturing - from 700 rubles per unit.

The price for standard, straight designs will be about 150 rubles per unit.

Braces materials

Metal

A traditional option that is characterized by maximum strength and efficiency. Allows you to correct defects of any complexity. Our orthodontists work with MEAW metal multi-loop arches, which allow you to correct the position of each tooth individually. The cost of installing metal braces is the most reasonable.

Ceramics

Such systems belong to the aesthetic type. The material is ceramics or artificial sapphires. The color of the elements is selected exactly to match the patient’s teeth, so the overlays are minimally noticeable when smiling or talking. There is less bacterial plaque formation on the ceramic surface. However, this option is not suitable for all clinical cases. The material is hypoallergenic and does not irritate mucous membranes. However, this option is also not suitable for patients with complex defects. We also note that the cost of installing ceramic braces will be higher than metal ones.

Combined

Within one system, ceramics can be installed on the front teeth, and metal on the chewing teeth. This will provide high strength in the side areas and aesthetics in the front. In addition, this option allows the patient to save significantly, since the price of ceramics and sapphires is much higher.
