Objective:To investigate the relationship among the congenital hypodontia of mandibular incisor and malocclusion and the variation of medial distal dimension of mandibular canine.
In this paper, we reported a case that simultaneously had maxillary bilateral impacted central incisors with dilaceration and mandibular bilateral fused lateral incisors and canines.
The paper reports that “the common finding was a narrowing of the mandibular dental arch and a decrease in maxillary arch length, causing an incisor cross-bite.”
Up front, it had long, canine-like teeth for killing prey, but it also had distinct incisors and teeth in back that pointed backward, perfect for dismembering carcasses.
