Correction of reverse bite

Correction of reverse bite is orthodontic treatment for a bite in which the lower front teeth sit in front of the upper front teeth when the mouth closes. This bite pattern is commonly called an underbite. Similar-looking bites can have different causes, so treatment begins by determining whether the problem is mainly related to tooth position, a functional forward shift of the lower jaw, the skeletal relationship between the jaws, or a combination of these factors.

The aim is not simply to move the lower teeth behind the upper teeth. An orthodontist first assesses how the teeth meet, whether the lower jaw changes position during closure, whether facial and jaw growth is still occurring, and how much of the problem is dental versus skeletal. This distinction determines which treatment options are realistic and whether orthodontic tooth movement alone can provide the intended correction.

Dental, functional and skeletal reverse bite

A primarily dental reverse bite can occur when the upper front teeth are positioned too far back, the lower front teeth too far forward, or both. In these situations, the main treatment objective may be controlled movement of the teeth and improvement of their relationship when biting.

Some patients have a functional forward shift of the lower jaw. An early tooth contact can guide the mandible forward as the patient closes the mouth, creating a reverse front-tooth relationship even though the underlying skeletal discrepancy may be limited. Recognizing this functional component is particularly important in children because it can affect treatment timing and appliance selection.

A skeletal reverse bite involves the relationship between the upper and lower jaws themselves, such as a relatively retruded upper jaw, a relatively prominent lower jaw, or a combination. A reverse bite should therefore not automatically be equated with a skeletal Class III malocclusion. The orthodontic diagnosis needs to establish how much of the visible bite comes from the teeth, function and skeletal anatomy.

An anterior reverse bite is also not the same as a crossbite, although the two can occur together. A crossbite may involve individual teeth or broader anterior or posterior segments. Other findings, such as crowded and misaligned teeth, may also be present and can influence the sequence and complexity of treatment.

Why patients consider correction

Patients may seek treatment because the reversed front-tooth relationship makes biting into food less comfortable, affects chewing contacts or contributes to uneven tooth wear. Some notice that particular teeth contact too early or carry more load than others. For other patients, the main concern is the appearance of the smile or facial profile. These concerns can be included in treatment planning without assuming that a particular facial appearance requires correction.

Children can be evaluated while the teeth and jaws are still developing. Parents may notice that the lower front teeth increasingly move ahead of the upper teeth, that the child shifts the lower jaw forward when biting, or that the bite changes as permanent teeth erupt. Early assessment can be useful, but it does not mean that every child should begin treatment immediately.

Adolescents may require reassessment as permanent dentition develops and facial growth continues. Adults can also be treated. In adults, because skeletal growth is largely complete, treatment planning places particular emphasis on whether the bite can be improved by safe orthodontic tooth movement or whether the underlying jaw relationship requires a different approach.

Orthodontic assessment before treatment

A detailed orthodontic examination is the starting point. The orthodontist evaluates the position of the front and back teeth, the dental arches, bite contacts, jaw function and facial proportions. Clinical photographs and a digital intraoral scan may be used to document tooth position and occlusion.

Radiographic diagnostics are selected according to clinical need. A panoramic radiograph may be useful for assessing teeth and supporting structures, while cephalometric imaging can help analyze the dental and skeletal relationship of the jaws. Additional imaging is not automatically required for every patient. Existing radiographs should be reviewed before new imaging is requested where appropriate.

In children and adolescents, remaining growth and the direction of jaw development are particularly important. Growth assessment helps determine whether an interceptive or orthopedic approach may offer benefit, whether observation is preferable, or whether treatment should be planned for a later stage.

How treatment is selected

Step 1: Identify the main component of the reverse bite

The orthodontist determines whether the problem is primarily dental, functional, skeletal or mixed. Oral health, gum condition, previous orthodontic treatment and the amount of space available in the dental arches are also considered.

Step 2: Consider age and remaining growth

Selected growing children may benefit from interceptive or dentofacial orthopedic approaches when clinically indicated. The exact appliance depends on the diagnosis and growth pattern. Early treatment may improve the developing bite and reduce the severity of the malocclusion, but it cannot guarantee that further orthodontic treatment or later orthognathic surgery will never be required.

Step 3: Select an orthodontic appliance

Fixed braces can provide controlled movement of upper and lower teeth and are used in many reverse-bite treatment plans. Conventional metal or esthetic fixed appliances and self-ligating systems are among the options available through orthodontic providers in Zagreb. Self-ligating brackets are one appliance design and should not be presented as the preferred solution for every reverse bite.

Clear aligners can be considered in selected dental and dentoalveolar cases when the required tooth movements and bite correction are suitable for aligner therapy. The choice depends on the severity of the problem, treatment objectives and patient cooperation. Clear aligners cannot be assumed to correct every significant skeletal jaw discrepancy.

Step 4: Decide whether orthodontic compensation is appropriate

In some older adolescents after growth and in adults with a mild or moderate skeletal discrepancy, orthodontic compensation or camouflage may be considered. This approach improves the bite by changing tooth positions without changing the underlying skeletal relationship between the jaws. The orthodontist must determine whether the required tooth movement can be achieved within safe biological limits.

Step 5: Consider interdisciplinary assessment when necessary

When a pronounced skeletal discrepancy is the main cause of the reverse bite, orthodontics alone may not provide the intended correction. Selected patients may therefore be referred for interdisciplinary assessment with an oral and maxillofacial surgeon to discuss combined orthodontic and orthognathic treatment. Surgery is not required for every reverse bite and has separate indications, risks, preparation and recovery considerations.

Key facts

• Main finding: the lower front teeth close in front of the upper front teeth.
• Diagnosis: dental, functional and skeletal components need to be distinguished.
• Age: children, adolescents and adults can all be assessed.
• Treatment options: may include interceptive treatment in selected growing patients, fixed braces, clear aligners in appropriate cases and combined orthodontic-surgical treatment for selected skeletal discrepancies.
• Follow-up: active orthodontic treatment requires regular controls and good oral hygiene.
• Retention: retainers are generally needed after active tooth movement to help maintain the result.

Results and realistic expectations

The objective is to create a more functional relationship between the upper and lower teeth, improve the front-tooth relationship and achieve more balanced bite contacts. The extent of correction depends on the original tooth positions, skeletal anatomy, remaining growth, periodontal health, treatment method and patient cooperation.

Orthodontic treatment can change tooth alignment and the appearance of the smile. Changes in facial profile vary considerably and depend on whether treatment involves tooth movement alone or correction of the underlying jaw relationship. Orthodontic compensation is therefore different from surgically changing the position of the jaws.

Correction of a reverse bite should also not be presented as automatically resolving speech difficulties, temporomandibular joint symptoms or every chewing complaint. These problems can have more than one cause and may require separate assessment.

Controls, oral hygiene and retention

Patients normally return for periodic controls throughout active treatment. The interval depends on the appliance, treatment stage and individual response rather than a single fixed schedule for everyone. Removable aligners, elastics or other patient-operated components also depend on consistent use according to the orthodontist's instructions.

Temporary tenderness or irritation can occur after placement or adjustment of orthodontic appliances. Good oral hygiene is especially important because plaque accumulation around appliances can increase the risk of enamel demineralization, cavities and gum inflammation. Orthodontic tooth movement also has biological limitations, including the possibility of root shortening or gum recession in susceptible patients.

After active treatment, retention is normally required because teeth can move again. The type of retainer and duration of wear are determined individually.

Organizing reverse bite treatment in Zagreb, Croatia

Reverse bite assessment and treatment can be organized through ZagrebMed and orthodontic providers in Zagreb, Croatia. The broader orthodontics service includes related examinations and treatment pathways for bite and tooth-position problems.

When sending an inquiry, include the patient's age, the main concern with the bite, information about any previous orthodontic treatment and any dental reports, photographs or existing X-rays already available. For a child, parents can also describe what they notice when the child closes the mouth or bites. New X-rays should not be obtained solely for the inquiry unless an orthodontic professional recommends them.

International patients should also indicate how often they could realistically return to Zagreb for orthodontic controls. This helps determine whether the expected follow-up schedule is practical before treatment begins.

To understand which correction approach may be appropriate, send ZagrebMed the information and records you already have and request an orthodontic assessment in Zagreb, Croatia.
