Orthodontic correction of a complex malocclusion of the canines of dento-alveolar and skeletal origin by means of a model cast device in the upper jaw in the dog

Malocclusion of the canines, which in dogs is frequent and often has a cong enital pattern, remains a challenge to treat. Steeply positioned lower jaw canines are corrected by means of a specifically designed orthodontic inter vention. The case at hand was characterized by a combination of a slight sk eletal distal bite and compensatory distal tilt of the entire premaxilla (r etrusion, caudal tilt) with a mesial tilt of the canines in the upper jaw ( rostral and anterior tilt). An individual solution was found which resulted in a functional adjustment of both upper and lower jaws. A model cast devi ce which included both appropriately tilted areas and screws to ensure dist al adjustment solved the problem.
