Lingual braces are installed not from the external, but from the lingual surface of the teeth, due to which they are absolutely not visible. There is only one indication for using this type of braces - the patient’s desire to make the conducted orthodontic completely imperceptible to others. Necessary condition - age must be over 12 years.

In Russia, the following lingual braces are mainly represented -
- braces "Stb" - manufacturer "Ormco", USA,
- brackets "In-Ovation-L" - manufacturer "Dentsply-GAC", USA,
- brackets "Incognito" - manufacturer "3M", Germany.
Lingual braces: benefits
1) The main advantage of lingual braces is only that your braces are not visible. Those. they give perfect aesthetics. This is important because Many people are complexing to wear traditional braces and feel psychological discomfort from them. Such invisible braces perfectly solve this problem.
2) A plus is a great safety in contact sports, the possibility of using musicians who play wind musical instruments. It is not unimportant that the risk of caries on the front surface of the teeth is reduced, which, even in the case of subsequent treatment and filling of these teeth, still worsens their aesthetics.

Comparison of lingual braces systems -
1. Lingual braces "Stb" -
Stb braces are ligature, i.e. The metal arc is attached to the bracket using special rubber ligatures. This is a very simple and universal system, unlike the "In-Ovation-L" and "Incognito" unligated brackets, in which the arc is fixed with the help of a complex locking mechanism on the surface of the bracket.
Stb braces are made of cobalt-nickel alloy, have standard shapes and sizes. Their thickness is only 1.5 mm, and the length is 4, 57 mm. Can be used in children from 12 years. Very simple and versatile system, more affordable than other lingual braces.
Recommendations for using Stb braces -
- It is recommended only for small and medium crowded teeth (with terms of treatment up to 24 weeks). When expressed crowding can not be used!
- Cannot be used if the jaw is too narrow or if there are problems with the temporomandibular joints.
- Can not be used with a low clinical height of the crowns of the teeth. In this situation, it will be possible to use only braces with fixation on the front surface of the teeth, or lingual braces "Incognito".
2. Lingual braces "In-Ovation-L" -
These braces are unligated (self-ligating). Those. On the surface of each bracket there is a snap lock that securely holds a metal arc in the bracket bracket. These braces are suitable for patients who plan to shift teeth up to 6 mm. They are made of a cobalt-nickel alloy, have standard sizes and shape.
Their main difference from Stb braces is that the In-Ovation-L lingual braces do not require the use of special rubber bands, with the help of which the metal arc is fixed to the metal plates. It seems to be convenient, but in fact, unligated braces are less versatile than regular ligature braces ...
Difference between Stb ligature braces and In-Ovation-L ligature-free braces:
The fact is that the fixation of the metal arc in the bracket bracket can be -
- active (when the contact is very tight, and the arc barely slips in the groove of the bracket),
- passive (when the arc can slide freely in the groove of the bracket, and fixing is to prevent the arc from simply falling out of the groove).
When using a ligature type of fixation with elastic bands or orthodontic wire, a doctor can very easily change the type of fixation from active to passive and vice versa, simply by relaxing or tightening the ligature. But at the castle anchorage unligated braces this option is not a ride, because they initially had only one type of fixation of the arc in the bracket groove: either active or passive.
Why is it important: The fact is that different types of fixation are more optimal for correcting various violations. For example, in order to correct the inclinations of the teeth, incorrect occlusion, one fixation is needed, for rotation of the teeth, expansion of the dental arch - another. Moreover, in the process of treatment the doctor repeatedly changes the types of fixation.
In traditional ligature braces, this is done elementary, but ligature braces with locks are completely deprived of such an opportunity. and the doctor has to use the type of fixation that was originally incorporated into the design of a specific model of braces. This leads to the fact that the treatment at some stage will not be carried out by the optimal type of load and will simply stall, plus the risk of complications will increase.
3. Incognito Lingual Braces -
These braces are ligature, i.e. elastic bands are still used to fix the arc to the braces. However, the manufacture of these braces is very different from the manufacture of any other bracket systems. If all other braces are standardized and are taken by orthodontists from special sets, then each bracket is made specifically for your tooth, on which it will be fixed.
Incognito braces are made for each patient individually using CAD / CAM technology (three-dimensional milling with a computer-controlled machine), and they are made of gold-bearing alloy. By production of metal arches for braces also robotized bending is used.
An interesting detail: making incognito braces is too complicated and cannot be done in Russia, so your impressions will be sent to Germany to the manufacturer of this braces system (to 3M). In 2-3 months courier mail will deliver individually made braces to the clinic, and you will be invited to install them.
Key properties of Incognito braces -
- Making braces will last about 2-3 months,
- treatment takes an average of 1.5-2 years,
- can be placed with a low clinical height of the crowns of the teeth.
Braces Incognito: reviews ...
- Problems in case of need of repair -
The fact that they are made in Germany according to your individual impressions means that in the event of any smallest breakdown it will be necessary to send the impressions again to Germany, and to wait several months until the restored parts arrive. In addition, the cost of repairs will be very large, and the treatment time will increase by at least another six months. Yes, and a break in treatment will not benefit.
Lingual braces - the most vulnerable to damage from all types of braces. But the situation is aggravated if you are not equipped with standardized braces, but individually made according to your teeth. After all, then it will not work - just get a new bracket from the box and replace it with the broken one.
Some orthodontists, having installed Incognito braces, in the event of a breakdown then simply refuse to treat this patient, leaving him to fend for themselves. Therefore, if you choose this type of braces - ask for a contract, which clearly states the obligations of the clinic and the guarantee, the terms of the repair.
Lingual braces: patient reviews
The main problem with this type of braces is that it is harder to get used to them and harder to wear than traditional braces on the outside of the teeth. The degree of discomfort will directly depend on the thickness of the plates of the lingual braces, which is completely different for different systems. The very first lingual braces had a thickness of 3.5 mm, whereas now the best samples of this type of braces can be only 1.5 mm thick.
In addition, manufacturers are constantly working to make the plates braces more rounded and smooth shape, which reduces the irritation of the language and the difficulty with speech. Nevertheless, if we compare even the best systems of lingual and traditional metal braces, the latter will be much more comfortable, and getting used to them will be more rapid.
The main problems you may encounter are:
- Longer duration of treatment -
The treatment process with lingual braces takes longer than the treatment with traditional braces fixed on the outside of the teeth. Be prepared for 3-4 months to wear these braces longer, and if a breakdown happens and repairs are required, then a few more months longer.
- Speech Difficulties -
it will be difficult for you to speak as you did before (at least initially). Many patients have a whistling sound when talking. The latter occurs because the tongue cannot touch the back surface of the front teeth when it makes certain sounds. However, gradually the speech is still normal.
- Soreness of the tongue -
curiosity (the desire to feel each braces tongue), as well as the constant friction of the tongue on the braces when talking can at first lead to redness of the mucous tongue, as well as pain. At first, salivation can also be observed.
- Hygiene Difficulties -
wearing lingual braces makes it even harder to maintain good oral hygiene, because Braces are also inaccessible for sight. The level of hygiene should be one order higher than when using traditional braces.
Feedback from patient surveys -
In 2005, a study was conducted among patients undergoing orthodontic treatment with lingual braces (by Caniklioglu). The survey showed that in 77% of patients speech returns to normal within 1 month, but 23% of patients experienced difficulties with speech and after 3 months of wearing braces.
The second survey showed that internal braces bring patients much more discomfort than conventional braces attached to the front surface of the teeth. 90% of patients spoke of high discomfort (especially at first). For comparison, only 27% of patients wearing traditional braces report discomfort.

Lingual braces: price 2019
The price range is very large. For internal braces - the price in different clinics may differ by almost 1.5 times, so it is worth spending a little time searching. The cost of braces depends not only on the pricing policy of the clinic, but also on the qualifications of the doctor, as well as on which list of works is included in the price.
1) Cost of consultation and diagnostics -
- Orthodontist consultation - usually free of charge
- diagnostics (removal and manufacture of impressions, analysis of diagnostic models, calculation of TRG, analysis of orthopantomogram, drawing up a treatment plan) - 1 600 rub.
2) Lingual braces: cost
below, we calculated the average cost of lingual braces in Moscow, which already includes installation of braces on 2 jaws, wire retainer, all work on fixation and removal (error of ± 10,000 rubles).
- Stb braces - price from 190,000 to 230,000 rubles.
- In-Ovation-L brackets - price from 250 000 rub.
- Incognito braces - price from 300,000 to 400,000 rubles.
- Monthly correction sessions usually cost another 2500 rubles, but Incognito braces correction costs more - about 7000 rubles.
Interesting fact: The cost price of one Stb bracket for a dental clinic is only 1000 rubles, the In-Ovation-L bracket is 2000 rubles (usually 20 braces are needed). The rest is the cost of the services of the doctor and the clinic surcharge.
Alternatives to lingual braces -
The best alternative to lingual braces is traditional braces, which are fixed on the front surface of the teeth. If you want to make them not too noticeable, then choose braces from ceramics or artificial sapphires. Another alternative may be detachable transparent kappa "Invisalign", but they are less effective than braces, and also not for all patients.
