The effects of spastic cerebral palsy on occlusion.

This research paper compares dental casts and lateral cephalometric radiographs of thirty children with spastic cerebral palsy with those of a control group to determine what effect spasticity and cerebral palsy have on dental occlusion and skeletal formation. Muscle spasticity can retard bone growth. Variations in the normal tonus of head and neck muscles can cause malocclusion and arch deformity.
