Multi-loop arc - all the pros and cons of the innovative technique

4188

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.

Situations in which filing of teeth is inevitable, and how safe the procedure is.

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.

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.

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.

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.

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.

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.

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.

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.

Installation

The installation procedure takes place in several stages:

1. 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.
2. 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.
3. Fastening the arch is carried out in a standard way using special locking latches with a snap mechanism.

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.

How to get the result

If you decide to visit an orthodontist, follow all the doctor’s recommendations to get the effect. After installing braces with a multi-loop arch, you need to visit the clinic regularly in accordance with the schedule recommended by your doctor. At the beginning of the correction, a thin arch is placed, over time it is changed to a thicker one, which creates more force. This must be done in a timely manner. As teeth shift, it is necessary to adjust the shape and size of the hinges. This is done by the orthodontist at the appointment.

To obtain the result, additionally, elastic bands are used between the upper and lower arches, which control the movements of the jaw, creating additional traction force. These devices speed up correction. They cause discomfort when chewing and talking, but if the doctor recommends wearing them, you should not ignore it.

While wearing braces, pay due attention to oral hygiene. It is difficult to remove food debris from under the wire loops; for this, special brushes are used after eating. If you do not pay attention to brushing your teeth, bad breath, caries, and gum inflammation will appear.

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.

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.

Treatment costs

Doctors at the Colibri Dental clinic apply in practice the progressive solutions offered by modern orthodontics; prices depend on the type of device, its material and the complexity of the clinical case. Fixing a brace system will cost from 60,000 rubles per jaw, monthly activation of braces will cost from 5,000 rubles, manufacturing a full set of Invisalign aligners will cost 365,000 rubles. The doctor will be able to determine the indications and choose the appropriate instrument only after examination and diagnosis.
