Malocclusion refers to the misalignment of teeth when the jaws close, altering how the teeth meet and the face looks. It is a widespread dental condition with various classifications, each exhibiting specific characteristics. Comprehending these categories is essential for designing an effective correction plan.

Neutral malocclusion is the most commonly observed type. In this scenario, the jaw relationship is normal, with the upper teeth slightly overlapping the lower ones. However, teeth may still be crowded, creating functional complications despite a correct skeletal foundation.

Type II bite occurs when the mandible is set too far back relative to the maxilla. This often creates a profile with a weak lower jaw and is typically an oversized upper jaw. Left untreated, it can increase risk of temporomandibular joint strain.

Class III malocclusion is the inverse of Class II, where the lower teeth and jaw jut forward beyond the upper. This may result from an enlarged lower jaw. Individuals with this condition often face challenges with biting and chewing, and may feel self-conscious about their appearance.

Other notable forms include unilateral or bilateral crossbite, where the biting relationship is inverted. This can occur in the front teeth and may induce jaw shifting. Anterior open bite describes a condition where the front teeth fail to contact when the jaws are closed. This is frequently linked to thumb sucking.

Horizontal protrusion measures how far forward the top incisors extend beyond the bottom ones. A significant horizontal discrepancy increases susceptibility to chipping or fracture. Deep bite occurs when the mandibular incisors contact the palate, potentially leading to discomfort during biting.

Malocclusions may stem from genetic inheritance, non-nutritive sucking patterns, post-injury growth disturbances, or abnormal tooth eruption. Early diagnosis, especially before permanent teeth fully erupt, enables more effective orthodontic outcomes. Treatment options may include clear aligners, headgear, 表参道 歯列矯正 or, in severe cases, jaw repositioning procedures.

Identifying the specific type of malocclusion is the essential starting point for effective treatment. A trained specialist can evaluate jaw alignment and design a tailored intervention based on the patient’s age. With early and appropriate care, nearly all bite issues are treatable, resulting in better oral health and a more confident, beautiful smile.
