Modern orthodontics can cope with almost all types of dental pathologies. The majority of defects are eliminated using various braces and orthodontic aligners. However, there are deviations, the correction of which requires the use of additional structures and greater effort from the patient.
The Brückle appliance is a removable orthodontic product designed to correct deep mesial bites.
Device and principle of operation
The effect of the device is due to its special design. The classic version of the orthodontic device is a plate that accurately follows the relief of part of the palate and gums.
The plate is equipped with an inclined plane in the form of a semicircular arc, which plays the main corrective role. The arch is located in the area of the anterior group of teeth. The structure is installed using built-in clasps (loops), which are placed on the last molars.

The operating principle of this design is based on the springy properties of the arch and the contractility of the muscles involved in chewing.
The whole correction process is as follows: while wearing it, the front teeth of the upper jaw touch the plate and are placed on it, which causes forceful pressure . Due to this effort, the lower crowns of the front row begin to gradually change their position, moving inward, and the upper ones towards the lips.
To maintain constant pressure, the dentist periodically corrects the acting arch, compressing it or stretching it.
Often, to increase the effectiveness of treatment, the dentist recommends using other orthodontic devices in conjunction with this device : a head cap, an extraoral elastic cord, a chin guard.
The listed additional elements will not only speed up the straightening process, but will also minimize the risk of the teeth returning to their previous position.
Purpose
This device is designed to normalize the position of teeth, both during the period of mixed and permanent dentition. But mainly it is prescribed to correct the bite of permanent teeth.
This is due to the fact that with a mixed bite, the jaw is not yet fully formed and more gentle methods can be used to straighten it .
The main indications for prescribing a Brückle appliance are the following orthodontic deviations:
- Deep bite in the lateral part of the dentition. The use of the device allows you to separate the tight fit of the crowns of opposite jaws.
- Mesial bite (gnathic form).
- Pronounced reverse incisal overlap, more than 3 mm deep.
- Inward displacement of the front row of teeth (palatal position of the crowns).
- Abnormal enlargement of the lower jaw.
- Macrodentia.
- Abnormal bite of neutral type.
- Prognathia of the lower jaw.
The decision on the advisability of using a Bruckle device to correct the bite in these pathologies is made only by the orthodontist.
Contraindications
The use of this device is not possible in all cases, as there are some restrictions. One of the main contraindications is the period of baby teeth. At this stage, the use of the device is considered too aggressive a measure, which may cause disruption of the correct formation of the jaws.
In addition, the device cannot be used to treat incisal overlap, the depth of which is less than 3 ml. The distal type of bite and crowding of the anterior teeth in the lower jaw are also contraindications.
Diseases of periodontal and dental tissue are considered relative contraindications. After they are eliminated, the device can be used.
Also, a temporary obstacle to installation will be the abnormal development of the frenulum of the lips and tongue . In this case, preliminary low-traumatic surgical intervention will be required.
Peculiarities
The design of the orthodontic apparatus is a removable device with a specially shaped plate and clasp fastening and an inclined plane. For manufacturing, durable plastic is used with a special part that is put on the teeth to be corrected. The device is attached to the supports with metal hooks that hold it in place.
This device is designed to correct deep or mesial overbite. The structure is placed on the lower jaw, fixation is carried out only on the molars.
The advantages of using the system are:
- the series is subject to a complex effect;
- installation and removal are simple and do not require special actions;
- correction efficiency is high;
- the arc of the device plays a fixing role;
- the jaw arch lengthens;
- there are no occlusal elements on the side;
- the device can be used during the retention period.
Minuses:
- treatment takes a long time;
- the number of readings is limited;
- additional devices are used;
- the cost is high;
- in the event of a breakdown, the device is manufactured anew, and treatment also begins literally “from scratch”;
- correction is frequent, the patient must visit the dentist at least twice a month.
Advantages and disadvantages
Like any other orthodontic device, this device has its advantages and disadvantages that distinguish it from other corrective devices.
Advantages:
- Unlike other devices, here the arc is not activated, but acts as a fixing element.
- Absence of occlusal type pads in the lateral sections of the device. This allows you to more effectively influence the jaw, helping to lengthen the dental alveolar arch.
- The plate can be removed and stored in a container at any time, so you can make it unnoticeable to others.
- When treating deep bites, this design showed the fastest effect.
- After treatment, the device can be used as a retention plate. To do this, you just need to cut off the inclined plane with a regular cutter and process the resulting sharp edges.
The disadvantages of the device include the following:
- High cost compared to similar designs.
- Duration of treatment.
- The need to use auxiliary elements.
- Constant adjustment. When using the Bruckle apparatus, adjustments are made once every two weeks.
- Also, one of the disadvantages is the fact that if it breaks down, you will have to wait for a new device to be made. And at this time, the dentition remains without pressure and the risk of reducing all effort to zero increases.
Reviews
According to patient reviews, this design does not cause discomfort, has a short period of adaptation and allows you to effectively solve the problem.
We invite patients who have had experience using the Brückle apparatus to share their feedback by leaving it in the comments to this article.

Manufacturing stages
Treatment with this device requires its individual manufacture.
Before this, the dentist conducts an examination to identify all dental problems and a detailed study of malocclusion.
Only after a complete history collection does the orthodontist begin to manufacture the device.
The whole process is divided into several stages:
- Taking an impression using a special material from the lower and upper jaws.
- Casting a working model from the received impressions.
- Manufacturing of the main components: clasps and vestibular arch.
- Strengthening elements on a working plaster model of the jaw. If it is necessary to retract the cuts of the lower row, the model of the jaw is covered with a cement layer on the lingual side in the area of the adjacent crowns. The upper part of the alveolar ridge is covered in the same way.
- Based on the resulting temporary structure, a wax base and a corrective inclined plane are modeled. Modeling is carried out in such a way that the plane overlaps the crowns of the incisors by 1/3 of their height. For this purpose, an impression of the front row of teeth of the upper jaw is used.
- The assembled workpiece is completely plastered in a cuvette, and then the wax is melted, replacing it with plastic.
At the same stage, they often engage in the manufacture of a chin guard. To do this, take a universal wax model, heat it and apply it to the chin.
While the wax has not hardened, the workpiece is pressed firmly against the surface for a minute. After hardening, the mouthguard is ready.
Installation and treatment
After production, the orthodontist invites the patient to install the device. The first installation is carried out directly by the doctor. He explains how the structure should be positioned correctly in the oral cavity and how the patient should feel.
Installation must be done on the lower row of teeth, so that the device does not touch the enamel of the crowns from their inner surface.
As a rule, treatment takes place in several stages:
- At the first stage, the device is used in conjunction with a rubber rod. The duration of treatment at this stage is 30 days for a temporary bite and 38 days for a permanent bite.
- The second stage begins when a neutral bite begins to form. The duration of treatment during this period for replacement teeth is 63 days, for permanent teeth 85 days. At this stage, the device is configured to expand the jaw arch.
- The third stage is final and is of a consolidating nature.
This implies the use not of the classic version of the Brückle apparatus, but of a retention one, that is, with a cut off vestibular plane. The duration of wearing a retention plate depends on the initial diagnosis and is determined by the dentist.
Throughout the treatment, it is necessary to regularly adjust the device. On average, this happens once every 2–3 weeks.
Price
The Bruckle apparatus itself has an affordable price, ranging from 3000-6000 rubles . The price here depends on the material used and the color design of the plate.
But it should be borne in mind that its production requires the use of the services of a dentist, which increases the final cost several times.
On average, the price of treatment using the Bruckle apparatus is 10,000 rubles . This cost does not include repairs to structures that were defective due to the patient’s fault.
Wearing and care
To obtain the desired effect from treatment, the device must be worn at least 20 hours a day .
In the first week after installation, it is not recommended to remove the structure even while sleeping and eating.
The best option would be to wear it constantly around the clock , allowing it to be removed only during meals and oral hygiene procedures.
It is recommended to use extraoral traction for 10 hours.
Throughout the use of the device, do not forget about proper care, because the general condition of the oral cavity depends on this .
Basic rules for caring for the device include the following recommendations:
- Cleaning the plate with a soft toothbrush must be done at least 2 times a day;
- for cleansing you need to use special aseptic gels, one of which is intended for daily use, the other is more powerful for 1 cleansing per week;
- during removal, the structure should be stored only in a special container;
- Once a week, soak the device in dental cleaning concentrate for 6–8 hours.
Price
The cost of the Brückle apparatus depends on the specific clinic, as it is manufactured individually. The average cost of the device itself is between 3 and 6 thousand rubles, but it is also necessary to take into account the costs of dental services.
As a rule, the manufacture and installation of the device costs patients approximately 10,000 rubles. Additionally, the cost of creating a wax impression and plaster cast, work on adjusting the device, and so on is taken into account. Manufacturing materials also affect the cost.
If the structure requires repairs due to improper handling and violation of medical recommendations, this service is paid for separately. It is not included in the total price of manufacturing, fitting and installation work.
