What is the most anterior superior point on the mandibular alveolus known as?

• A. Infradentale (Id)
• B. Pogonion
• C. Gnathion (Gn)
• D. Condylion (Co)

Answer: (A)

The most anterior superior point on the mandibular alveolus is known as the Infradentale (Id). This landmark is specifically defined as the point situated at the apex of the alveolar process of the mandible, below the central incisor teeth. It serves as an important reference point in cephalometric analysis, as it helps in assessing dental relationships and the position of the incisors relative to the mandible. Understanding the Infradentale is essential for evaluating the vertical and horizontal dimensions of the dental arch in relation to the rest of the craniofacial structures. The other options refer to different anatomical landmarks: Pogonion (the most anterior point on the symphysis of the mandible); Gnathion (the lowest point on the symphysis of the mandible); and Condylion (the most posterior point on the condyle of the mandible). Each of these points serves different purposes in cephalometric assessment, but they are not the most anterior superior point on the mandibular alveolus.
