DEFINITION - Dominant upper front premolars overhang lower premolars.
Causes - Hereditary - May result from horse born with an overbite. Developmental - May result secondary to molar malocclusion that forces jaw out of alignment.
RESULTING PROBLEMS - Prevents horse from chewing freely side to side resulting in improper and excessive molar wear. Can cause excessive wear to opposing lower premolars, severe bit problems, riding issues and trauma to soft tissue.
SOLUTION - Reduce dominant portion of upper premolars, rounding unopposed portion of upper premolars smoothly toward gum. Requires preventative maintenance to prevent reoccurrence.
