Fixed braces in Cologne – brackets for children & teens
From classic metal brackets to nearly invisible, self-ligating ceramic brackets: in Cologne we treat children, teens and adults with modern fixed braces – precise, gentle and made in our own in-house master dental laboratory.


Fixed braces (multi-bracket appliances) correct misaligned teeth and bite discrepancies with precision. Small brackets are bonded to the teeth and gently moved via a wire – for children, adolescents, and adults.
At our practice in Cologne, we treat with fixed braces – from simple corrections to pronounced misalignments. Which bracket system fits is determined in advance through careful diagnostics.
How do fixed braces work?
Fixed braces (multi-bracket appliances) move teeth precisely within the jawbone — with similar precision to an aligner system (e.g., Invisalign). The brackets are attached to the outside of the teeth, either made of metal or — less visible — tooth-colored ceramic. If it’s particularly important to you that the treatment is barely noticeable, clear aligners are usually the better solution.
Fixed braces are a proven and effective method for correcting misaligned teeth. They consist of brackets that are bonded to the teeth and archwires that move the teeth into the desired position.
The treatment time with fixed braces varies depending on the type and extent of the misaligned teeth and can take from several months up to a few years.1 During treatment, the braces have to be adjusted regularly by the orthodontist in order to monitor progress and to optimize the correction of the misaligned teeth.
It is also important to maintain good oral hygiene during treatment and to avoid certain foods and habits that can damage the braces or harm the teeth. These include hard or sticky foods, chewing ice or biting your nails.
In many cases, fixed braces can be a better option than other correction methods such as Invisalign, especially with more severely misaligned teeth. An experienced orthodontist can recommend the most suitable treatment method and provide individual advice in order to achieve the best possible results.
The average active treatment duration with fixed braces in studies is around 20 months (range depending on the individual case).1 Recent review articles do not change this: For crowding, the duration did not differ demonstrably between clear aligners and fixed braces18, nor between the two common bracket slot sizes19. However, the strength of this evidence is limited.
Modern brackets are smaller and more comfortable than they used to be – for complex misalignments, fixed braces remain indispensable.

Fixed braces for children and teens
For children and adolescents , fixed braces are often the treatment of choice. When permanent teeth are erupting and space is needed for them at the same time, we often treat this with fixed braces. The same applies when the upper and lower teeth do not fit together precisely when biting (occlusion). Aligner treatment is often equally possible.
Anyone playing sports with fixed braces should also wear a custom-made sports mouthguard : it is made to fit over the brackets and protects the lips and cheeks in case of a blow or a fall.


Fixed braces for adults
In orthodontics for adults in Cologne as well, we can place fixed braces when treatment with aligner therapy is not an option. This includes uprighting tipped teeth or orthodontic treatment in connection with an osseointegrated anchorage.
Comparison of the different bracket systems:
Various bracket systems are used in our orthodontic practice. What is the difference? Take a look at our comparison:




Treatment with multibracket appliances
Modern superelastic wires and bracket systems (e.g., the Damon bracket) move teeth with consistent, relatively low forces. After the bracket is bonded to the tooth, the tooth surface can be sealed.

Self-ligating brackets
The Damon System is one of the so-called passive self-ligating systems, first brought to market by Ormco in 1996 and continuously refined since then.
In orthodontics , the term “ligation” refers to the connection between archwire and bracket, which is created, for example, by elastic rings or thin metal ligatures.
Self-ligating brackets on fixed braces
contain a small clip that can be closed, holding the wire in position. Rubber bands or ligatures are no longer needed. Without rubber ligatures, there are fewer places for plaque to accumulate — oral hygiene becomes easier.
The principle: The sliding door allows the wire to move freely within the bracket, resulting in lower friction and reduced force compared to conventional brackets. The brackets are available in metal and ceramic.

For patients, this means:
- No changing of elastic ligatures at check-up appointments
- Easier oral hygiene, as no rubber ligatures hold plaque
- Lower friction between wire and bracket
- Whether teeth must be extracted in case of crowding depends on the findings — we clarify that during treatment planning.
We work with materials from Ormco and American Orthodontics.
Treating temporomandibular disorders (TMD, often called TMJ) with fixed braces
For patients with temporomandibular disorder (TMD) , treatment initially focuses on gentle, reversible measures, usually with an occlusal splint. If a dental or bite misalignment is also present as a contributing cause, we discuss after splint therapy whether orthodontic treatment with fixed braces (multibracket appliance) or the Invisalign system is appropriate. Fixed bite ramps can maintain the mandibular position established with the splint while teeth are moved in individual segments. The fixed bite ramps are removed gradually. Manual therapy or osteopathic treatment may be performed concurrently.

What does fixed braces cost – and when does health insurance pay?
For children and adolescents with recognized treatment need (KIG grade 3 to 5), statutory health insurance covers fixed braces as standard care: it pays 80 percent of the costs directly; the 20 percent co-payment is refunded after successful completion of treatment.§ Requests beyond standard care – such as ceramic braces or self-ligating braces – are billed separately; we discuss what additional costs these entail before treatment begins.
Below KIG 3 and for adults, fixed braces are a private service. For reference: Depending on the findings, type of braces, and treatment duration, costs typically range between 3,000 and 8,000 euros. Private health insurance and supplemental dental insurance reimburse depending on the plan; costs can be paid in installments interest-free for up to 18 months. What applies in your case is stated in writing in the treatment and cost plan before treatment begins — not only on the invoice. An overview is available on our costs and insurance page. How the KIG classification works is explained in the section on indication groups further below.
Frequently asked questions / FAQ about fixed braces
Tap a question to open the answer.
Which fixed braces are best?
There is no such thing as the “best” braces – which type suits you depends on the findings and the treatment goal. The common options:
- Metal brackets: sturdy, proven and effective, but visible.
- Ceramic brackets: tooth-colored and less noticeable, but more fragile.
- Self-ligating brackets: do not require elastic ligatures; a clip holds the wire.
Which option makes sense for you is something we discuss in the consultation. In a twelve-month clinical comparison study, ceramic brackets came loose more often, at 15.9 percent, than metal brackets, at 9.1 percent – but they are less noticeable.
Here you will find an overview of all types of braces: fixed braces, removable appliances and clear aligners.
How many days do fixed braces hurt?
In the first few days after the braces are placed or adjusted, the teeth are often sensitive to pressure – this is normal and comes from the pressure that moves the teeth. There may also be rubbing against the cheeks and lips. The discomfort usually subsides within a few days, once the lining of the mouth has gotten used to it. It can be eased with soft food and, if needed, a pain reliever such as ibuprofen or acetaminophen. If severe pain lasts longer, you should have the braces checked. For most people, the feeling of pressure eases noticeably after about 3 to 5 days.
Which is better, fixed braces or a removable appliance?
That depends on the findings. Fixed braces – brackets plus archwires, bonded firmly to the teeth – are suitable for more pronounced misalignment and are worn continuously. A removable appliance corrects milder misalignment or holds the result after treatment as a retainer ; it can be taken out. Often the two are combined. What fits depends on the severity of the misalignment, on age and on individual factors. In direct comparison studies, the difference in the result achieved at the overjet – the horizontal distance between the upper and lower front teeth – was less than one millimeter between fixed and removable appliances. What matters is therefore which misalignment is present, not which type of device.
What do fixed braces achieve?
Fixed braces correct misaligned teeth and jaw anomalies. The benefits:
- Alignment: corrects overbite, underbite, crossbite and open bite as well as crowding.
- Esthetics: an even smile strengthens self-confidence.
- Oral hygiene: straight teeth are easier to clean.
- Function: can improve how the teeth work together during biting and chewing.
- Durability: with good follow-up care, the results last long-term.
Treatment takes time, good oral hygiene and regular check-ups. In children with markedly protruding upper front teeth, the risk of an injury to the front teeth is two to three times higher. In Germany, it is assumed that about 40 percent of ten-year-olds have a need for orthodontic treatment, and around 456,700 treatments are newly planned each year.
How much do fixed braces cost without health insurance coverage?
Without coverage by health insurance, the costs usually range between 3,000 € and 8,000 €, depending on the findings and the type of braces. How high they turn out to be depends on the type of braces, the length of treatment and the effort involved.
When do you get braces free of charge?
Statutory health insurance covers braces for children and adolescents if treatment begins before the 18th birthday and medical necessity exists – for example, in cases of significant misalignment of teeth or jaw (classified as KIG grades 3–5). Statutory health insurance pays 80 percent of the costs directly; the 20 percent patient contribution is reimbursed after successful completion of treatment. Esthetic alternatives such as ceramic brackets cost extra. The requirements are the same for all statutory health insurers – we will determine with you whether medical necessity exists and which options are available.
What do fixed braces for children cost with statutory health insurance (e.g. AOK)?
For children and adolescents with recognized treatment need (KIG grade 3–5), fixed braces are covered by statutory health insurance such as AOK: The insurance pays 80 percent of the costs directly; the 20 percent co-payment is reimbursed after successful completion of treatment. Below KIG 3, treatment is usually private (approx. 3,000–8,000 euros).
Can you pay for braces monthly?
Yes. With us, the cost of braces can be paid monthly directly to the practice through an installment plan — interest-free for up to 18 months. For reference: Without statutory health insurance coverage, costs typically range between 3,000 and 8,000 euros, depending on the findings and type of braces.
Which braces are the least expensive?
The most affordable option is usually conventional fixed metal braces — proven and comparatively inexpensive. Less visible alternatives such as Invisalign or ceramic brackets cost more. The exact costs depend on region, practice, and findings. From KIG 3 onward, fixed metal braces are a covered benefit: The insurance pays 80 percent directly; the 20 percent co-payment is reimbursed after successful completion; below that, treatment usually costs approx. 3,000–8,000 euros.
How long do teeth keep shifting after braces?
After treatment, teeth tend to shift again – how much depends on your predisposition, the treatment and the follow-up care. This is why retainers (fixed or removable) stabilize the result. They are usually worn for at least six months to a year at first, and often permanently. It is important to follow the retention recommendations consistently.2
When are braces not possible?
In most cases, braces are possible at any age. In some situations, however, they are not advisable or only make sense after preliminary treatment:
- severe jaw abnormalities that require surgical correction
- too little bone or too little space for the teeth
- advanced gum disease or other serious dental problems
- severe allergy to the materials the braces are made of
These points do not automatically rule out treatment. Before we begin, we examine thoroughly whether braces make sense, and we name alternatives if needed. Treatment can only be covered by statutory health insurance if it begins before the patient’s 18th birthday – the only exceptions are severe jaw anomalies that also require oral surgery. If oral hygiene remains inadequate over the long term despite instruction, the treatment goal has to be redefined or the treatment ended – with fixed braces, about one third of patients develop new white decalcification spots.
How quickly do braces work?
How quickly something changes depends on the initial findings, the type of braces and the severity of the misalignment. The teeth already move slightly at the start, but a visible result takes time. Depending on the case, treatment lasts from a few months to several years, during which the teeth are under continuous gentle pressure. We check the progress regularly and inform you about the expected time frame. Depending on the case, treatment with fixed braces usually takes about 1.5–2.5 years.
Can the treatment time with fixed braces be shortened?
The duration depends above all on the findings and cannot be shortened at will. Consistently keeping the check-up appointments and maintaining good oral hygiene do, however, help keep the treatment within the planned time frame without delays. In one study, every missed appointment extended treatment by about a month on average, as did every phase in which elastics were worn carelessly – regular appointments and consistent wear are therefore the most effective lever. For vibration devices that promise shorter treatment, a benefit for the overall treatment time has not been demonstrated so far.
Classification System of Orthodontic Indication Groups (KIG)
In Germany, the Classification System of Orthodontic Indication Groups (KIG) is used to assess the need for orthodontic treatment on the basis of clinical findings.
Orthodontists use the system to assign misaligned teeth and jaws to five different categories. Depending on the category assigned, the treatment costs are covered by the health insurers or offered as a private service.
The KIG system helps to ensure a clear structure in the treatment of misaligned teeth and jaws and to determine the corresponding entitlement to benefits from the health insurer.
Rapid Palatal Expansion (RPE)
Rapid palatal expansion is a fixed appliance for skeletal widening of the upper jaw. It was first published in 1860 by Angell in the USA. Rediscovered after 1945 by Haas, Timms, and Derichsweiler, RPE has since secured its irreplaceable place in orthodontics.
The appliance is usually attached with bands on the 1st molars and 1st premolars. Today the appliance can also be used as a plastic splint that encompasses all posterior teeth. The appliance is equipped with an expansion screw in the middle, with which the two halves of the upper jaw can be pushed apart by up to 10 millimeters in two to four weeks. New bone then forms in the resulting gap. This remodeling takes several months; the appliance remains in place and is monitored during this time.
Palatal expansion is indicated for patients with a narrow upper jaw. A substantial portion of the widening achieved with palatal expansion is skeletal, meaning it results from new bone formed in the midpalatal suture; the younger the child, the greater this portion typically is.
In addition to widening the upper jaw, palatal expansion is attributed a favorable influence on nasal breathing. This has been studied especially for nasal airway resistance and for children with obstructive sleep apnea: In a systematic review, the apnea-hypopnea index improved significantly in a large proportion of treated children after palatal expansion.17 Whether this leads to fewer infections, fewer ear or sinus problems, or better sleep in individual cases cannot be concluded from this. Palatal expansion is often good preparation for subsequent treatment with orthodontic appliances, the Invisalign system, or fixed braces.
During the first days of activation, a sensation of pressure or tension in the upper jaw is common, sometimes extending into the nose or forehead. Less commonly, slight tooth mobility or reddened, mildly inflamed gums may occur.

Carrière Distalizer
The Carrière Distalizer is a completely passive appliance that only becomes active through the use of Class II elastics. The nickel-free appliance is placed on the back teeth and therefore leaves the visible front area largely free.
A clear retainer tray combined with small buttons in the opposing jaw provides the anchor point for the elastic rubber bands. The hinge, the decisive component of the distalizer, enables targeted distalization of the canine and simultaneous distalization and derotation of the molar.
In cases of a Class II bite, we like to use the distalizer before an Invisalign treatment.
Patient example
Anchorage technique in orthodontics
Very difficult tooth movements have become possible through an anchorage that is fixed to the bone. Anchorage means that we take the support we need for moving a tooth from this point.
Example cases
Intrusion of an elongated molar with mini-screws and Invisalign
The following images show the intrusion of an over-erupted upper molar through a treatment with Invisalign combined with mini-implants and elastics. Placing two small screws on the cheek side and the palate side of the tooth to be intruded provides an ideal point of application for the Invisalign aligners and for the additional force from the elastics. The treatment made it possible to create an ideal starting situation for the implant restoration in the opposing jaw.

Positioner
Once the brackets and bands have been removed, the phase of fine adjustment and retention begins. The supporting structures of the teeth are not yet fully stabilized, so the result can still be perfected with what is known as a positioner and the teeth can be brought into their ideal position.
This requires several steps in the laboratory . Individual teeth or groups of teeth are separated from the plaster model and repositioned individually into the ideal arrangement of the dental arches. The positioners are then fabricated over this ideal arch using a special thermoforming technique.
