Crossbite: Posterior Crossbite (Interceptive)

Pre-treatment: A posterior crossbite, where the upper back teeth fit inside the lower back teeth is often caused by under-development of the upper jaw. It can result in a shifting bite and asymmetric facial form as well as crowing of the permanent teeth.


Post-treatment: A preventative course of orthodontic treatment (without braces) was able to develop the upper jaw to its proper size, eliminate the shifting bite, eliminate the crossbite and generate room for the permanent teeth. The need for braces was greatly reduced.
