Brachy = short
gnath = jaw
Malocclusion in which one side of the mandible or maxilla is disproportionate to its other side. Skeletal defect in which the affected animal has a non-symmetrical head. The upper and lower incisors do not align.
Wry bite or wry mouth
Malocclusion in which the upper fourth premolar lies palatal to the first molars. Incisors are in the normal relationship, but the posterior teeth are not. The upper fourth premolars are either palatally displaced or mandible is wider than the maxilla in the premolar area.

Base-narrow mandibular canines
Malocclusion in which one or more of the upper incisor teeth are caudal to the lower incisors. Most common orthodontic abnormality. The premolar relationship is a normal scissor occlusion, but one or more of the incisors are misaligned.

D. Overirrigates the tooth socket so that no clot can form.
Gingivoplasty is described as
The removal of hyperplastic gingival tissue
To protect the pulp tissue of teeth from thermal damage during ultrasonic scaling, one should A. Use constant irrigation B. Change tips frequently C. Use slow rotational speed D. Use appropirate amounts of paste
A. Use constant irrigation
