The term "Angle Class III" is commonly used in dentistry to describe a specific type of malocclusion, or misalignment of the teeth. The spelling of this word can be explained using the International Phonetic Alphabet (IPA), which represents the sounds of speech. "Angle" is spelled /ˈæŋ.ɡəl/ in IPA, and "Class III" is spelled /klɑːs θriː/. Together, the term is pronounced as /ˈæŋ.ɡəl klɑːs θriː/. It refers to a condition where the lower jaw protrudes significantly past the upper jaw, causing the teeth to overlap in an abnormal way.
Angle Class III refers to a specific dental classification of malocclusion or misalignment of teeth, characterized by an abnormal relationship between the upper and lower jaws. It is commonly known as a "Class III malocclusion" or an "underbite." In this condition, the lower jaw protrudes or extends beyond the upper jaw, causing the lower front teeth to overlap or close in front of the upper front teeth. This creates a reverse or negative overjet where the lower teeth are positioned in front of the upper teeth when the mouth is closed.
The Angle Class III malocclusion is typically congenital and may be caused by various factors, including genetics, excessive growth of the lower jaw, or underdevelopment of the upper jaw. It can also be influenced by certain habits like thumb sucking or tongue thrusting.
Patients with Angle Class III malocclusion may experience oral health complications, such as difficulties in chewing, speaking, and oral hygiene maintenance. Additionally, they may face aesthetic concerns due to the visible protrusion of the lower jaw.
Treatment options for Angle Class III malocclusion typically involve orthodontic interventions that aim to correct the alignment of the teeth and jaws. This may include the use of braces, dental appliances, or in some cases, orthognathic surgery to reposition the jawbones. Early detection and timely treatment of this dental condition are crucial to achieving optimal oral health and improving the overall facial appearance of affected individuals.
