•Class 3 malocclusion is a type of dental misalignment where the lower teeth and jaw protrude forward in relation to the upper teeth and jaw. This type of malocclusion is also known as prognathism, underbite, or negative overjet.
•Class 3 malocclusion can be further classified into two subtypes:
•True Class 3: In this subtype, the lower jaw is significantly protruded forward, causing the lower teeth to overlap or come in front of the upper teeth. The upper front teeth may also be retruded or sit behind the lower front teeth.
•Pseudo Class 3: In this subtype, the lower teeth are in a normal position, but the upper teeth are retruded, giving the appearance of an underbite.
•Class 3 malocclusion can cause various issues, such as difficulty in biting and chewing, speech problems, and aesthetic concerns. Orthodontic treatment, such as braces or clear aligners, can help correct Class 3 malocclusion and improve dental function and appearance. In some cases, additional treatments, such as jaw surgery, may be necessary to correct severe cases of Class 3 malocclusion. It’s important to consult with a dental professional if you suspect you have a malocclusion or other dental issue.
