What are the three classes of Malocclusions?
Class I – Neutrocclusion
Class II – Distocclusion
Class III – Mesiocclusion
Class I – Neutrocclusion
Maxillary and mandible are both aligned but one or more teeth are misaligned
Class II – Distocclusion
The teeth in the maxilla occlude rostral to the mandibular equivalents
Class III – Mesiocclusion
Mandibular teeth occlude rostral to the maxillar equivalent
What is Neutrocclusion and what are the types?
-Rostral cross bite (RXB)
-Caudal cross bite (CXB)
-Linguoversion (LV)
-Mesioversion (MV)
-Mesioversion (MV)
Canine teeth that are in the right position anatomically in the dental arch but that is abnormally angled in a mesial direction
-Linguoversion (LV
Mandibular canines are not in correct anatomical position but are lingually displaced
-Caudal cross bite (CXB)
the mandible is wider than the maxilla in the area of the premolars
-Rostral cross bite (RXB):
One or more of the maxillary incisors are displaces so they are lingual to mandible incisors
The maxillarys and the mandible are correctly aligned.
-Malocclusion class 1
What is Distocclusion?
-An overbite
-Genetic
-Maxillary prognathism: Maxilla is forward
-Mandibular retrognathism: mandible is caudal
What is Mesiocclusion
-Underbite
-Genetic

-Crown of tooth may look normal but the tooth may have little to no root left
-20%-70% of cats have this
What are 7 common dental diseases in dogs and cats?
-FORLS
-Malignant tumors
