Overview
Crossbite is an occlusal irregular condition where a lower tooth has a more buccal position than the antagonist upper tooth. Crossbite can involve a single tooth or a group of teeth. Crossbite can be classified as anterior or posterior.
- Anterior crossbite can also be referred as negative overjet, and is typical of class III skeletal relations (Progenism). * Posterior crossbite is often correlated to a narrow maxilla and upper dental arch. A posterior cross-bite can be unilateral or bilateral.
Unilateral cross-bite often determines a lateral shift of the mandibular position, which can become structural if left untreated for a long time during growth, leading to skeletal asymmetries.
There are several therapies that can be used to correct a cross bite: Multibrackets therapy (braces), Quad-Helix, Hirex, Removable Plates, Invisalign, Delaire Mask. The correct therapy should be decided by the orthodontist depending on the type and severity of the crossbite.
