90855-8
ClinicalPosterior inter-arch deviation Teeth and gum
Definition
The posterior or 'back' teeth should overlap with the top (maxillary) teeth partially overlaying to the outside. When the lower posterior teeth are partially overlaying the top, this is a posterior crossbite or inter-arch deviation most likely due to the top arch form being too narrow and too small.
