Structure and/or Key Feature(s)

There are five fiber types in the alveolodental ligament:

—alveolar crest fibers;

—apical fibers;

—horizontal fibers;

—interradicular fibers;

—oblique fibers (Rajendran and Selvam, 2015).

Anatomical Relations

Alveolar crest fibers extend from the cervical region of the tooth to attach to the alveolar crest (Rajendran and Selvam, 2015).


Alveolar crest fibers, along with the other fibers of the alveolodental ligament, are responsible for anchoring the root cement to the alveolar bone (Rajendran and Selvam, 2015).
