Dentofacial deformity may cause malocclusion and can involve heredity, systemic influences including infectious, nutritional, endocrine, and toxic effects, or local factors such as delayed loss of primary teeth that may result in crowding.1 In class Imalocclusion, both jaws are of normal length and the teeth are in a normal mesiodistal location with malposition of one or more individual teeth. The goals of orthodontic therapy are to provide an adequately functional, stable, and comfortable occlusionby altering the position or presence of the natural teeth.1 The goal of providing an esthetic occlusion is difficult to consider since an esthetic occlusion is only required for show dogs and would be considered unethical if the clinician had knowledgeof the owner's intention to show the dog since a change in appearance is grounds for disqualification.
