Horizontal fibers (J) attach to the cementum apical to the alveolar crest fibers and run perpendicularly from the root of the tooth to the alveolar bone. Oblique fibers (K) are the most numerous fibers in the periodontal ligament, running from cementum in an oblique direction to insert into bone coronally.
In the coronal direction, the periodontal ligament is continuous with the lamina propria of the gingiva and is demarcated from the gingiva by the collagen fiber bundles which connect the alveolar bone crest with the root (the alveolar crest fibers).. the attached gingiva (AG). On the vestibular and lingual side of the teeth, the free gingiva extends from the gingival margin in apical direction to the free gingival groove which is positioned at a level corresponding to the level of the cemento-enamel junction (CEJ).
