Skeletal Cross Bite
Skeletal cross bites are caused by an under development of the Maxilla. These cross bites often appear to be a unilateral problem. However, on close examination the patient frequently has a skeletal shift of the mandible epsilateral to the cross bite. This in turn means the mandibular condyle on the side of the cross bite is distal to its correct relationship on the articular disk.
When the maxilla is properly developed bilaterally, the condyle is free to regain its correct position on the disk. As this occurs the deviation of the mandible return to normal. Proper diagnosis and treatment will result in long term stability.
