A malocclusion where one or more teeth in the upper arch sit inside the lower arch is defined as a crossbite. This misalignment can affect single teeth, groups of teeth, or the entire dental arch. Correcting this condition aims to align the teeth properly, achieving a functional and esthetically pleasing bite.
Addressing this occlusal discrepancy is crucial for several reasons. It can improve chewing efficiency, reduce strain on the jaw joint, and prevent excessive wear and tear on teeth. Additionally, correcting this malalignment can enhance facial aesthetics and improve overall oral health. Historically, early intervention has been emphasized to guide proper jaw development in children.
