Crossbite is a type of malocclusion where the upper and lower teeth do not align properly. It can affect a single tooth or a group of teeth and can occur on either or both sides of the mouth. Crossbite can be classified into two types: anterior crossbite and posterior crossbite.
Types of Crossbite[edit | edit source]
Anterior Crossbite[edit | edit source]
