An overjet is classified as a Class II malocclusion.
Understanding Malocclusions
Malocclusion refers to the misalignment of teeth or jaws. It’s essential to understand that in a healthy bite, the upper front teeth should slightly project beyond, and overlap the lower teeth. This overlap is what's referred to as "slight."
What is a Class II Malocclusion?
According to the reference, an overjet is a specific type of malocclusion characterized by the upper front teeth projecting further beyond the lower teeth than they should. This excessive horizontal overlap defines it as a Class II malocclusion.
- Class I: Normal bite with slight overlap.
- Class II: Overjet where upper teeth significantly protrude over the lower teeth.
- Class III: Underbite where the lower teeth protrude in front of the upper teeth.
Characteristics of an Overjet (Class II Malocclusion)
Here are some key traits of an overjet:
- Protrusion: The upper front teeth extend noticeably further forward than the lower teeth.
- Increased Horizontal Overlap: The overlap is more pronounced compared to a normal bite.
Implications of an Overjet
An overjet can affect:
- Aesthetics: Can impact the appearance of the smile and facial profile.
- Function: May interfere with biting, chewing, and speech.
- Oral Health: In some cases, can increase the risk of injury to protruding teeth.
Solutions for Overjet
- Orthodontic Treatment: Braces or clear aligners can correct the alignment of the teeth.
- Jaw Surgery: In severe cases, surgery may be necessary to realign the jaws.
