maxillary arch

The **maxillary arch** refers to the curved structure formed by the upper row of teeth anchored in the maxilla, or upper jawbone. It plays a crucial role in dental anatomy, oral function, and overall facial aesthetics. The maxillary arch supports the upper teeth, assists in chewing and speech, and works in harmony with the mandibular arch (lower jaw) to ensure proper bite alignment. Understanding the maxillary arch is essential for dental professionals when planning treatments such as orthodontics, prosthodontics, and oral surgery.
