What characterizes the external oblique ridge?

The external oblique ridge is accurately characterized as a linear area of bone located on the external surface of the mandible. This prominent bony ridge runs obliquely along the lateral aspect of the mandible and provides attachment for the buccinator muscle and the superficial fascia of the face. Its location and structure are crucial for dental professionals as it serves as an anatomical landmark during dental procedures, especially in the context of surgery and the placement of implants.

Understanding the anatomy of the external oblique ridge also aids in assessing the morphology of the mandible and in recognizing potential variations that may influence clinical practice. This ridge is distinct from other structures such as those found in the maxilla or nasal cavity, which are not associated with the external surface of the mandible.
