The characteristic changes in the radiographic appearance of the alveolar bone is seen in:

Fibrous dysplasia The density and trabecular pattern of fibrous dysplasia lesions vary considerably. The variation is more pronounced in the mandible and more homogeneous in the maxilla. The internal aspect of bone may be more radiolucent, more radiopaque, or a mixture of these two variations compared with normal bone. The internal density is more radiopaque in the maxilla and the base of the skull. Segmental odontomaxillary dysplasia The density of the maxillary alveolar process is increased, with a greater number of thick trabeculae that appear to be aligned in a vertical orientation.
