The
premaxilla (or
praemaxilla) is a pair of small
cranial bones at the very tip of the upper jaw of many animals, usually, but not always, bearing
teeth. In humans, they are fused with the
maxilla and the term "premaxilla" can also be used as a synonym for
incisive bone. Other terms used for this structure include
premaxillary bone or
os premaxillare, and
intermaxillary bone or
os intermaxillare.
