Angle Class II refers to a classification system used in orthodontics to describe a specific type of malocclusion or misalignment of the teeth. It is named after Edward Angle, an American orthodontist who developed the first comprehensive classification system for dental malocclusions.
In Angle Class II, there is a discrepancy between the upper and lower jaws, leading to a specific relationship between the teeth in the anterior (front) and posterior (back) regions of the mouth. The condition is characterized by the upper front teeth, known as the maxillary incisors, being positioned too far forward or protruding over the lower front teeth, known as the mandibular incisors. This can result in an overbite, where the upper teeth vertically overlap the lower teeth to a greater extent than what is considered normal.
Angle Class II malocclusion may also present with other dental issues, such as crowded or crooked teeth, dental midline discrepancies, and variations in the alignment of molars. The condition can cause functional problems, such as difficulty in biting and chewing, as well as aesthetic concerns.
Treatment for Angle Class II malocclusion typically involves orthodontic interventions, including braces or clear aligners, to gradually move the teeth and jaws into proper alignment. In some cases, growth modification appliances may be used in younger patients to guide jaw development. In more severe cases, orthognathic surgery might be required to correct the skeletal discrepancies of the jaw. Regular monitoring and follow-up with an orthodontist are essential to ensure successful treatment outcomes and long-term stability.
