Does a slight overbite need to be corrected?

Patients with mild overbite can return to normal through correction. If it is not treated, it will completely affect people's appearance, making the lips look deformed and affecting normal chewing of teeth. This is very serious. Over time, it will cause gastrointestinal indigestion in patients. Therefore, patients must wear some functional correctors.

1. Headgear and traction chin cup correction device

Suitable for patients with early skeletal anterior crossbite and mandibular protrusion. It can be used in the late stage of deciduous teeth, the stage of replacement teeth or the early stage of permanent teeth. Can be used in conjunction with intraoral appliances such as occlusal splints and tongue spring orthodontics.

2. Front traction correction device

It is suitable for early skeletal anterior crossbite with maxillary underdevelopment and mandibular protrusion, and can be used during the period of replacement teeth or the early stage of permanent teeth.

3. Functional orthosis

For example, activator or Frankel type III. It is suitable for early skeletal anterior crossbite and functional anterior crossbite, and can be used in the period of tooth replacement, especially in the late stage of tooth replacement.

4. Class III traction correction device

It is mainly used to adjust the mesio-maxillary relationship and is often used for early skeletal anterior crossbite. It can be used in the late stage of replacement teeth or the early stage of permanent teeth. The intraoral correction device can be a removable upper and lower occlusal pad corrector, or a fixed corrector, or a combination of the two.

5. Removable maxillary occlusal pad and tongue spring corrector

It can be used to correct any anterior crossbite and can be used alone or in combination with other plastic surgery devices.

6. Fixed braces

Both edgewise square wire arch braces and Begg braces can be used to correct anterior crossbite and are often used during the replacement or permanent tooth period. When using the Begg appliance, Class III traction should be performed instead of Class II traction, with a traction force of about 80 grams.

7. Correction of anterior crossbite in adults

If it is an odontogenic anterior crossbite or a mild skeletal anterior crossbite, the above-mentioned correction devices with non-plastic force can be used for correction. If the anterior crossbite is combined with obvious skeletal deformity, combined orthodontic-orthognathic surgery treatment is required.

Due to poor breastfeeding posture, etc., the functional excessive protrusion of the mandible causes mandibular protrusion and anterior crossbite, but the mandibular shape and size are basically normal, and the mandible can retract to the edge-to-edge relationship of the anterior teeth, which can be called pseudomandibular protrusion. If not corrected early, it may develop into true mandibular protrusion over time.

In addition to clinical manifestations, the diagnosis of this disease can be assisted by X-ray cephalometric measurement.
