Dental malocclusion is malpositioning of [[:Category:Teeth - Anatomy & Physiology|teeth]] where there is no obvious skeletal abnormality, i.e. there is no jaw length or width discrepancy.

'''Anterior Crossbite''': This is a clinical term used to describe a reverse scissor occlusion of one, several or all of the incisors. The condition can be secondary to persistent primary incisors. However, there is probably a skeletal origin as well, since affected animals often develop a mandibular prognathic bite. In other words, an anterior crossbite in an immature animal may be the first sign of a developing mandibular prognathism. The cause can either be a dental malocclusion (i.e. linguoversion of the upper incisors) or a skeletal malocclusion (i.e. mandibular prognathism or maxillary brachygnathism). <font color="red">Pic8 malocclusion</font color>

'''Malocclusion of the Canine Teeth''': The two most common abnormalities in canine tooth position are:
* Rostral displacement (mesioversion) of the maxillary canines (also known as lance canines). Persistent primary canines may be responsible for this condition. A breed predisposition has been reported in the Shetland sheepdog. <font color="red">(pic9malocclusion)</font color>
