Deep overbite cases require prompt orthodontic correction. Often neglected, severe deep overbite significantly compromises dental aesthetics and personal appearance. So how should deep overbite be addressed? Let's explore the insights from specialists at professional cosmetic dental hospitals.
Experts explain: Deep overbite refers to a malocclusion where, in a normal bite, the upper front teeth cover one-third of the lower teeth. How to address deep overbite? Different correction methods are applied based on the degree of overbite.
While most people focus on underbites (reverse overbites), they often overlook deep overbites, dismissing them as merely cosmetic issues. However, deep overbites pose significant health risks: the upper teeth cannot form a proper bite relationship, making it easy for the lower teeth to injure the upper gum tissue. This can also lead to periodontal issues in the front teeth and temporomandibular joint disorders.
Oral specialists emphasize that patients should undergo examination at specialized dental hospitals, where correction methods are tailored to the specific degree of deep overbite. Clinically, deep overbite is categorized into the following degrees:
Grade I: The upper tooth crown covers 1/3 to 1/2 of the lower tooth, classified as mild deep overbite. Treatment typically involves raising the height of the posterior teeth while maintaining the anterior teeth unchanged.Wear a removable appliance with a flat guide plate and pads on the maxilla. After posterior tooth elevation, perform additional supplementary corrections.
Grade II: Moderate deep overbite where the maxillary crown covers 1/2 to 2/3 of the mandibular tooth. This requires lowering the anterior teeth while maintaining the height of the posterior alveolar bone.Treatment options vary by patient condition and may include fixed appliances, removable appliances, etc.This requires a combined approach of lowering the front teeth and raising the back teeth. Orthodontic appliances used include fixed appliances, functional appliances, and guides. Severe cases may also require surgical intervention.
Deep overbite can be considered the counterpart to dental malocclusion, both requiring early intervention. Correcting these issues before age 18, when jaw bones are still developing, yields twice the result with half the effort.
