Gingival Fibers

Gingival fibers : are connective tissue fibers that inhabit the gingival tissue adjacent to teeth and help hold the tissue firmly against the teeth. They are primarily composed of type I collagen, although type III fibers are also involved. _________________________________________________________________ 🔷️ Alveologingival Group : These fibers originate from the crest of the alveolar bone and inserts into lamina propria of the free gingiva. ____________________________________________________________ 🔷️ Circular Group : This fiber group forms a band around the neck of the tooth. Together with the gingival group of fibers, these fibers bind the gingiva to the neck of the tooth. ____________________________________________________________ 🔷️ Dentogingival Group : The dentogingival group of fibers they originate from the cervical cementum (near cementoenamel junction) and inserts into the connective tissue of the free gingiva.Among the gingival group of fibers, these are the most frequent fiber bundles. ________________________________________________________________________ 🔷️ Dentoperiosteal Group : These group of fibers they originate from the cementum slightly below the dentogingival fibers and inserts into the outer cortical plate of the alveolar bone. ____________________________________________________________ 🔷️ Alveolar crest Group : The alveolar crest fibers originate from the cementum just below the cementoenamel junction (CEJ) and insert at the crest of the alveolar bone. ____________________________________________________________ 🔷️ Horizontal Group : The horizontal group of fibers presents below the alveolar crest group and they originate from the cementum and at a right angle to the long axis of the tooth inserts into the alveolar bone. ____________________________________________________________ 🔷️ Oblique Group : The oblique group of fibers originates from the cementum and in an oblique direction inserts into the alveolar bone lining the socket coronally. The oblique group of fibers is more in number as compared to other principal fiber groups.
