DEFINITION - Upper incisors on one side of mouth are excessively long and lower incisors opposite side are excessively long, causing incisors to meet on a diagonal.
Causes - May develop over time if horse chews more in one direction. Often caused by asymmetry of the arcades and tables.May occur secondary to molar malocclusions or as a result of a missing incisor or incisor damage causing opposing incisors to become excessively long.
RESULTING PROBLEMS - Cause horse to excessively wear molars on one side of mouth and opposite side molars become overly long resulting in a sheared molar table angle. Can result in major TMJ pain. Look for lack of symmetry of face, body, TMJ and temporal muscles. When ridden, stiff and lack of flexion on one rein verses the other.
SOLUTION - Reduce wedged incisors allowing proper lateral excursion and molar contact. Equilibrate corresponding molar malocclusions. For the horse to reach his potential will need accurate and detailed proper equine dentistry to follow up on corrections on a regular basis.
