The term "maxilar" refers to the upper jawbone in humans and many animals. It plays a crucial role in the structure of the face and supports the teeth. The maxilla is paired, meaning there are two maxillary bones that form the upper jaw, contributing to the formation of the orbit, nasal cavity, and palate. In dental anatomy, the maxilar is significant because it holds the upper teeth in place. It also connects with other facial bones, such as the zygomatic bone and nasal bone, helping to shape the overall facial structure. Proper alignment of the maxilla is essential for effective chewing and speaking.
