Suitable for patients with early skeletal anterior crossbite and mandibular protrusion. Can be used for late deciduous teeth, replacement teeth or early permanent teeth. Can be used in combination with oral appliances, such as occlusal pad tongue spring appliance.

2. Front traction correction device

It is suitable for early skeletal anterior crossbite with maxillary hypoplasia and mandibular protrusion, and can be used for dentition replacement or early permanent teeth.

3. Functional orthodontics

For example, an activator or frankl III type III. It is suitable for early skeletal anterior crossbite and functional anterior crossbite, and can be used in dentition replacement period, especially in the late dentition replacement period.

4. Class 4.III traction correction device

It is mainly used to adjust the relationship between mandible and mandible, often used for early skeletal anterior crossbite, and can be used for late dentition or early permanent teeth. The orthodontic device may be a removable upper and lower occlusal pad appliance, a fixed appliance, or both.

5. Removable tongue spring appliance for maxillary occlusal pad

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

Repair electrical appliances

Both edgewise edgewise edgewise appliance and Begg appliance can be used to correct anterior crossbite, which is often used in mixed dentition or permanent dentition. When using Begg appliance, Class III traction should be used instead of Class II traction, and the traction force should be about 80g.

7. Treatment of adult anterior crossbite

1. During breastfeeding, correct bad breastfeeding posture and avoid excessive stretching of the baby's jaw.

2. It is particularly important to keep the gap between early deciduous teeth and early deciduous molars as much as possible. Pull out the reserved teeth as soon as possible, especially the reserved lower deciduous molars.

3. Due to chronic tonsillitis, tonsil diseases should be treated in time.

4. The malocclusion of anterior teeth caused by insufficient abrasion of deciduous teeth can make the mandible reset itself through excessive occlusion interference.
