Fundamentals of small animal orthodontics.

The basic principles and concepts that govern the discipline of orthodontics are explored. The movement of teeth is mediated primarily through the periodontal ligament. When the periodontal ligament is stretched, bone apposition occurs. Conversely, in areas of compression, bone resorption occurs. The subject tooth moves in the direction of the force. The orthodontist must be cognizant of the prevailing ethical guidelines and the functional needs of the patient.
