Sutura intermaxillaris, also known as the intermaxillary suture, is the line of junction between the two maxillary bones at the midline of the upper jaw. This suture separates the two halves of the maxilla and is a crucial structure in craniofacial development. Synonyms for sutura intermaxillaris include the intermaxillary articulation, maxillary suture, and intermaxillary joint. Additionally, the sutura intermaxillaris is also referred to as the incisive suture since it is usually located closer to the incisors and provides a stable foundation for the central incisor teeth. Understanding these synonyms is essential in properly communicating and diagnosing craniofacial abnormalities related to this key suture.
