A smooth edge or ridge on the buccal surface of the body of the mandible that ranges from the anterior border of the ramus, with lessening prominence, downward and forward to the region of the mental foramen. This edge or ridge remains unchanged in size and direction for the most part throughout life. It is where the buccinator muscle attaches and affords a consistent landmark for the construction of dentures and subperiosteal implants.
An anatomical landmark that is a continuation of the anterior border of the mandibular ramus and extends obliquely to the region of the first molar. It serves as an attachment of the buccinator muscle and appears superior to the mylohyoid ridge on a dental radiograph.
