Maxillary mandibular asymmetry ( also called wry bite , especially by breeders ) is a skeletal malocclusion in which one side of the jaw grows differently from the other side ( Figures 5A and 5B )
Dental malposition
Abnormally placed teeth can result in the following conditions :
Rostral cross bite occurs when the canine and premolar teeth on both sides of the mouth are normally aligned but one or more of the lower incisors are positioned in front of the upper incisors ( Figure 6 ).
Mesioverted mandibular canines ( also called lingually displaced canines or base narrow canines ) occur when the lower canine teeth protrude inward , impinging on or penetrating the maxillary gingiva ( Figure 7 ). Often this condition is due to

retained deciduous teeth . The resulting trauma can be alleviated through tooth movement , crown reduction and restoration , or extraction .
Rostroverted maxillary canine ( also called lance canines ) may be inherited ( Shetland sheepdogs are prone to this condition ) or developmental secondary to retained deciduous teeth ( Figure 8 ). Treatment includes moving the maxillary canine caudally with the help of orthodontic brackets and elastics , crown reduction and restoration , or extraction . vet360 Issue 02 | MAY 2018 Issue
