Orthodontic treatment methods for underbite (crossbite) of teeth

Traditional orthodontic methods primarily adjust tooth position through fixed braces and dental tracks. This approach is suitable for mild to moderate cases of underbite, with treatment typically lasting 1–2 years. Regular hospital visits are required for adjustments, which may lead to poor oral hygiene and negatively impact patients' quality of life. Self-ligating braces are a newer type of orthodontic appliance that automatically adjusts tooth position, reducing the number of required clinic visits. This method is suitable for moderate to severe underbite cases, with treatment generally lasting 1–2 years. Clear aligners are transparent trays that discreetly correct teeth, minimizing impact on patients. This method is appropriate for mild to moderate underbite cases, with treatment usually lasting 6 months to 1 year. Clear aligners require patients to wear them at least 22 hours per day and avoid eating hard foods.
