Deviations in the development of occlusion, as a rule, are detected in patients of a younger age group - and already during this period it is possible to carry out therapeutic measures aimed at eliminating a specific anomaly. The Andresen-Goipl activator is prescribed in situations where correction of a mixed or permanent bite is required, and is a removable structure that is fixed on the upper and lower rows and forms a single active block that affects the jaw region. The device is created taking into account the individual anatomical features of the structure of the oral cavity, and is allowed for installation starting from the second stage of the formation of the primary occlusion, helping to eliminate cross and mixed occlusion by changing the relative position of the elements.
Description of design and principle of operation
The Andresen-Goipl activator is a removable appliance that is usually worn after the second period of occlusion of primary teeth. Correction is recommended for various jaw deformities. It is used in permanent and mixed dentition to correct dental anomalies.
The Andresen-Goipl apparatus consists of two plates, which are the base, and a Coffin spring, with which they are connected. At the top of the device there are special wings adjacent to the palate and surface of the tongue. And also the design is complemented by cavities for teeth to ensure reliable fixation during use.
A thin wire is placed on the top plate, which only touches the top of the teeth. In the lower part, special recesses are made to cover the cutting surfaces of the row. Because of this, the chewing parts of the bite are moved back by 2 mm.
The operating principle of the design may differ depending on the nature of the violation. For this reason, the device is manufactured individually for each patient. There are several options for restoring your bite:
- Fixation of the extended lower jaw in the required position. After installation, the device begins to stimulate bone growth in the right direction.
- Preventing growth of the maxillary row.
- Resumption of the work of muscle fibers that are involved in the chewing process.
- Changing the location of the dentition using special elements of the apparatus. Correction can be carried out in several directions simultaneously.
The desired result is achieved due to the fact that the jaw adapts to the position of the activator parts.
Complications of open bite
Like any other dental pathology, an open bite can cause a number of complications. In addition to aesthetic defects, which can be expressed in a constantly open mouth, deformation of the jaw, chin and other parts of the face, this also concerns the functioning of internal organs. Especially in this case, the gastrointestinal tract suffers. Since a person with an open bite cannot fully chew food, especially hard food, it ends up in the stomach in this form. As a result, gastroenterological diseases may develop that will require serious and long-term treatment.
Another common complication is distortion of a person's speech. Since an open bite eliminates the barrier to the tongue, the opportunity for full articulation also disappears. In this regard, it becomes simply impossible to pronounce some sounds.
Important! It is necessary to remember that without correcting the malocclusion itself, it will not be possible to improve speech. Therefore, you should not waste time on speech therapists and other specialists, but it is better to immediately contact a professional orthodontist.
Activator manufacturing process
Since each Andresen-Goipl monoblock is produced individually, the doctor must take a plaster cast of the jaw. The resulting model indicates the location of the apparatus body and the cutting path. Depending on the indications, the dentist may also mark locations for levers, springs and other additional elements.
Before manufacturing the activator, the doctor must make sure that all parameters are taken into account. Namely:
- the anterior border of the plates covers the cutting and chewing surfaces of the teeth;
- the rear border of the template is located parallel to the line of connection of the lateral parts of the teeth.
Bite blocks are also added to the test model. If sized correctly, the bottom of the cast will touch the sublingual area, and the wax will occupy up to 35% of the coronal part of the structure.
The final structure contains a lot of wire, differing in diameter. So, depending on the location, it is used:
- Coffin spring - about 1.3 mm;
- base parts - 0.7 mm;
- outer part - 0.8 mm;
- internal - 0.65 mm.
In order to complete the template, the clinician must determine the occlusal tangents. In the process, the lower jaw is moved to the correct position and then fixed. The resulting model is covered with heated wax on the surface of the palate and the closure of the teeth.
Next comes the installation of clamps, which will later be included in the activator design. Before insertion into the wax model, the fixing elements are preheated.
Monoblock with Coffin spring
The free space between the occlusal surfaces is filled with wax. After placing the bite ridges, both impressions are combined for final manipulations. The dentist makes final changes to the design of the device and thickens the blank in the sublingual area. After this, the doctor can begin creating a plaster model.
The final form is filled with plastic. The frozen activator is sharpened and polished. The last step is sawing the base along the line that the doctor designated at the very beginning of the creation of the device. Before handing over the product to the patient, the specialist must make sure that all parts of the structure are functioning correctly.
Design features
Bionators are divided into the following groups:
- By location - on one of the jaws, on both at the same time (i.e. monoblocks).
- By fixation - removable, non-removable, combined.
- In terms of functionality - for preventive or therapeutic purposes.
Structurally corrective devices combine elements of 2 types - active, passive:
- arcs;
- expansion parts (screws, springs);
- orienting loops;
- inclined planes.

At this address https://orto-info.ru/sistemyi-vyiravnivaniya-zubov/individualno-izgotovlennyie-apparatyi/vo-vremennom-prikuse-haasa.html we will discuss the purpose of the Haas apparatus in orthodontics.
Scheme and duration of treatment
The treatment program will largely depend on the type and complexity of the problem. The most common problems and uses of the activator include:
- In case of disorders that manifest themselves in the form of an uncharacteristic narrowing of the jaw, the vestibular arch will be located on the front teeth of the upper row. And it is also necessary to fix the Coffin spring in the center of the surface of the palate.
- If there is a noticeable protrusion of the lower jaw forward, it is recommended to use an Adresen-Goipl monoblock with an expansion screw. In this case, the vestibular arch should be positioned along the front teeth.
- If the upper canines are not positioned correctly, the curves of the arch are set at the medial edges. All elements must be well tightened to create strong pressure.
Since the structure of the dentition is different for each person, there is no universal solution to the problem. Only a specialist can select the final treatment format.
Just like the specific treatment regimen, the duration of wearing the device will depend only on the complexity of the correction. In addition, other problems may be discovered during treatment, the correction of which will take some more time. More accurate forecasts can be made only after the first results appear. Correction can take from 2 months to 4 years. Most often, children wear a two-jaw appliance for about 1 year. If you wear the product for a long time, some parts may need to be replaced.
Most children find it inconvenient to use the device during the day, so they put it on before bed so that it does not interfere with conversation. This is also one of the reasons for the long treatment period, because the child does not wear the device all the time.
Treatment period
It was noted above that the treatment regimen is determined by the characteristic disorders. When correcting a distal bite, characterized by a narrowing of the jaw row, a vestibular arch is installed on the upper front teeth. The Coffin spring is attached to the middle part of the palatal suture.
For mesial occlusion, wearing an activator with an expansion screw is recommended. The vestibular arch runs along the mandibular anterior teeth. To eliminate violations associated with the location of the upper row of canines, the bends that relate to the specified arch are placed on the medial edges. These elements are then tightened to create additional tension.
The duration of treatment with the activator depends on the individual characteristics of the patient. On average, restoration of the bite takes about 1.5 years. In some cases, treatment is completed several months after installation of the device.
The design makes communication difficult, which is why it is usually used at night.
This is interesting: Types of vestibular braces
The use of the design is extremely contraindicated for patients who have problems with nasal breathing.
Advantages and disadvantages
The cost of producing a monoblock and the duration of treatment make parents doubt the proposed solution to the problem. When weighing all the features of the device, one should take into account not only the speed and effectiveness of such correction, but also possible discomfort and complications for the child. The device has a lot of positive qualities:
- The activator can be removed and put on independently, which simplifies the process of brushing teeth and eating. In addition, the child will not feel embarrassed because of a foreign object in the mouth, which prevents him from communicating with peers throughout the day.
- The product is easy to clean, so the child can wash the device independently at a convenient time.
- Simple operating rules.
Despite the fact that the activator has obvious positive characteristics, it should be noted that this type of treatment also has its disadvantages:
- Due to the fact that the device can be removed at any time, the child may not follow the operating instructions. If the product is not worn for the prescribed number of hours, the treatment results may not be noticeable.
- The device must not be used if breathing through the nose is impaired, as it completely blocks the ability to breathe through the mouth. Therefore, before starting the course, you should undergo an examination by an otolaryngologist.
Negative aspects can be avoided if parents take control of the entire process of correcting the bite and monitor compliance with the doctor’s instructions.

Similar orthodontic appliances
The Andresen-Goipl activator refers to closed two-jaw orthodontic devices. However, there are also open monoblocks that do not cover the palate and the front parts of the teeth. Open ones include:
- Janson Bionator. Often used for prognathic distal occlusion. Restrains the growth of the upper row, due to which the bite is corrected.
- The Klammt activator is prescribed to correct the uncharacteristic arrangement of the anterior teeth, as well as for sagittal anomalies. The device has a lighter design compared to other devices. Due to the fact that there is no plastic on the roof of the mouth, the device does not impede speech and can therefore be used throughout the day.
- The Balters bionator is used to correct narrowing of the dentition, protrusion of the anterior teeth and deep bite, open bite and malocclusion of the lower jaw.
Considering that modern dentistry offers a wide range of options for solving the problem of malocclusion in children, parents will be able to give their child a beautiful smile.
Diagnosis of open bite
Often, diagnosing an open bite does not require much time. Usually, the doctor can point out this pathology during the first examination of the patient. To confirm the diagnosis, he can schedule an additional visit to the orthodontist, who can more competently determine the causes of malocclusion and prescribe comprehensive treatment.
If malocclusion was identified at an early age, the doctor may recommend taking an X-ray of the jaw. It is needed to determine the condition of permanent teeth that have not yet appeared on the surface.
Application of the Andresen-Goipl apparatus
Many bite pathologies and anomalies of individual teeth can be corrected in childhood if you choose the right correction program. In different clinical cases, certain types of orthodontic appliances are used.
Quite often they resort to the Andresen-Goipl apparatus, which has been used in orthodontic practice for more than 50 years. During this time, the design was improved, but its essence did not change.
Let's take a closer look at the design features and operation of this device.
Features and principle of operation
The Andresen-Goipl activator means a removable device consisting of two bases; they are made for each jaw separately. The parts are connected in a special way to achieve protraction of the lower jaw. This is necessary in order to slow down the development of the upper jaw and accelerate the development of the lower jaw.
The design is complemented by other auxiliary components: screws, retraction arc, Coffin springs. The orthodontist determines which elements to use in the design based on the characteristics and complexity of the clinical case. Thus, the design is adjusted individually to each patient and can be modified depending on the specific situation.
The device works by moving the lower jaw forward and fixing it in this position. This provides favorable conditions for its growth, and also regulates the work of the facial muscles responsible for chewing and facial expressions. This device is used primarily during the period of mixed dentition to correct various pathologies and disorders due to influence in three planes at once.
In what cases is it used?
Action in three planes provides a fairly wide range of application of this device in orthodontic practice. As already mentioned, the device is most effective during the period of mixed dentition, when dental pathologies are most easily corrected. The Andresen-Goipl monoblock is used for treatment in one of the following cases:
- signs of distal bite;
- preventing tooth displacement;
- stimulating the growth of the lower jaw or inhibiting the development of the upper;
- correction of the width of the dentition;
- abnormal arrangement of individual teeth;
- very wide interdental spaces.
The period of mixed dentition usually lasts in children until approximately 12 years of age. The dental system of a child at this age is not yet fully formed, so its development can still be influenced, which significantly reduces the time for correction.
Pros and cons of the device
Before agreeing to treat their child, parents carefully weigh the advantages and disadvantages of each correction method. They care not only about efficiency and the final result, but also about the degree of comfort for the child. Based on this, we can highlight several pros and cons of this design. The advantages include the following.
- Possibility to remove the device during meals and brushing teeth. The device is worn mainly during sleep, since it is impossible to talk to it, so the child will not feel embarrassed in front of his peers.
- Easy maintenance of the structure compared to braces. Even the child himself can cope with it.
- There is no need to spend a long time in the dental chair. The device is manufactured in a laboratory and then given to the patient’s parents. The first installation is carried out by a doctor.
Thus, the treatment is quite comfortable for the child and at the same time effective. But some disadvantages cannot be ignored.
- Since the device is removable, parents cannot always ensure that the child wears it for the required time. And this greatly affects the results of treatment.
- The Andresen-Goipl device is contraindicated for wearing if you have problems with nasal breathing. It completely blocks the ability to breathe through the mouth.
You should always listen to the opinion of a specialist if he believes that a particular orthodontic device will most effectively solve a child’s bite problem. You can always discuss all your concerns with the orthodontist and find a compromise that will be comfortable for the patient and effective in terms of treatment.
How long do you need to wear the device?
This question is asked by all patients or their parents if it turns out that it is necessary to use a not very convenient design that will limit them in some way. But at the initial stage of treatment, even an experienced orthodontist with experience can only give an approximate answer.
1 – bed for teeth; 2 – plastic monoblock; 3 – vestibular wire arch
The duration of treatment is very individual. The timing is affected by the characteristics of the patient’s dental system, his age, the severity of the pathology and its nature.
Only some time after the start of the correction, when the doctor sees the first changes, will he be able to approximately say when the treatment will be completed. The full course of treatment can end in just a few months or last up to two or even three years.
In most cases, treatment lasts about one and a half years, so you can focus on this period.
On average, you need to see an orthodontist every two weeks to activate the device and adjust the retraction arch and, if necessary, add plastic to the areas of the teeth being moved. Other adjustments may be made to the original design to achieve a better treatment result.
As already mentioned, it is recommended to wear the device mainly at night, when there is no need to talk or breathe through the mouth.
Depending on the complexity of the pathology, daytime wear may be recommended. The timing of correction depends on the number of hours per day that the child spends with the device in the oral cavity.
You can see what elements the structure consists of in the photo above.
How is the device made?
Proper manufacturing of the structure, taking into account the problem and all the features of the patient’s dental system, is a guarantee of effective and shortest possible treatment. The device is manufactured in the laboratory in several stages.
- Impressions of the patient's teeth are taken and models of both jaws are made from plaster.
- Templates with occlusal ridges are created from wax.
- The orthodontist determines the contact of the teeth of opposite jaws and their location relative to each other.
- The resulting models are installed in a special device that simulates the movements of the lower jaw.
- Next, select and manufacture all the auxiliary elements that will be used in a particular case. First of all, this is an arc, springs and screws.
- An exact reproduction of the future design is made from wax.
- Based on the results of the work done, a device is made that fully corresponds to all the individual characteristics of the patient and the tasks to be solved.
An individual approach and precision of all actions performed allow you to minimize treatment time and achieve good results, so you should contact only qualified specialists. If the doctor recommended your child to wear the Andresen-Goipl activator, then you will probably be interested in seeing this design in the final video.

Andresen-Goipl apparatus
Anomalies in the development of bite are detected at an early age. Modern technologies make it possible to begin treatment at the initial stages, correcting defects and ensuring the aesthetics of the smile and restoration of the normal functioning of the jaw. One of the effective correction tools is the Andresen-Goipl apparatus.
Description and principle of operation
The Andresen-Goipl orthodontic activator is a structure of two bases connected to each other using a Coffin spring, for the manufacture of which a wire with a cross-section of 1.5 mm is used.
Thanks to two “wings” located at the top of the product, a tight fit of the system to the sky is achieved.
Fastening to the teeth is ensured by recesses that touch the cutting surfaces, which allows the rows to be separated by a distance of two millimeters.
Based on the specifics of the anomaly, the operation scheme of the device is determined. The following methods are possible:
- extension of the lower jaw with subsequent fixation in a given position;
- change in the position of the dentition in perpendicular planes.
As a result of treatment, the basic functions of the masticatory muscles are restored, the bite is leveled and defects in tooth growth are corrected.
Activator manufacturing process
Preparing the system includes several stages. At the preliminary stage, a plaster cast is formed, which is the basis for creating a model of the jaw. Based on the obtained sample, the doctor marks the boundary of the base, and also indicates the placement points of auxiliary structures and the cutting trajectory.
During the manufacturing process, specific factors are taken into account:
- the front border of the apparatus should lie along the cutting surfaces of the top row;
- the posterior border is determined by the line of closure of the lateral units;
- the lower part should cover the sublingual area.
The design is modeled based on the characteristics of the jaw structure.
The space between the surfaces is filled with a wax mass, after which bite ridges are installed, combined with the upper model.
The finished device is filled with plastic, polished and ground. The bases are sawed in accordance with the originally intended line, after which the functional operation of the system is checked.
Scheme and duration of treatment
As already mentioned, the treatment regimen depends on the specifics of the defect being corrected.
In cases where the distal bite, which is characterized by a narrowing of the jaw row, is subject to correction, the arch is placed on the frontal upper incisors, and the Coffin spring is attached in the middle of the palate.
To treat mesial occlusion, technology with an expanding screw is used; the structure is secured to the lower units. Correction of canine anomalies involves medial placement of the vestibular arch.
The duration of treatment is determined by the physiological characteristics of the patient, and on average ranges from 12 to 18 months. Considering the difficulties associated with the difficulty of realizing speech function when the activator is installed, it is recommended to use it during sleep.
Advantages and disadvantages
The method under consideration has a number of advantages, confirmed by reviews of specialists and patients. These include:
- the ability to remove the structure for eating and performing routine hygienic procedures for oral care;
- ease of care of the device, especially in comparison with braces;
- quick completion of procedures in the dental office, which is especially important for young patients.
Treatment with the Andresen-Goipl activator is a comfortable and painless procedure that is easily tolerated by children of any age. It is important to follow a number of rules to ensure that the desired result is achieved:
- due to the ease of dismantling the removable structure, it is necessary to organize monitoring of the child’s actions, observing the duration and frequency of wearing recommended by the dentist;
- in case of problems with the respiratory system, in particular, with difficulty passing air through the nasopharynx, it is recommended to stop using the device, since its installation eliminates the possibility of breathing through the mouth.
