The difference between bony and dental teeth is usually defined for dental disorders. Osseous dental disorders refer to misalignment of the teeth caused by underdevelopment or overdevelopment of the alveolar bone. In addition to the normal correction of dental disorders, the skeletal deformity is also corrected. Orthodontic disorders are those in which the bones are normally developed, and there is no displacement by x-ray, but the teeth are crowded or protruding, which can be corrected by orthodontic treatment. Bony dental disorders require treatment at a specific age, such as 9-12 years old, which is the best age for correcting skeletal developmental malformations. If this age is exceeded, subsequent surgical intervention is required for treatment, but the results are not as good as when performed at the appropriate age. The results of orthodontic treatment for dental malformations are more satisfactory.
