What are Transseptal fibers?
THE transseptal fibers are those groups of collagen fibers comprising a liga- ment-like band, arising in the cementum of the proximal surface of a tooth. subjacent to the gingival fiber group and running across and above the bone. crest to an adjacent tooth.
Where are Transseptal fibers found?
Transseptal fibers (H) extend interproximally over the alveolar bone crest and are embedded in the cementum of adjacent teeth; they form an interdental ligament. These fibers keep all the teeth aligned. These fibers may be considered as belonging to the gingival tissue because they do not have an osseous attachment..
What are Dentogingival fibers?
type I collagen fibers collected into fiber bundles within the subepithelial connective tissue of the gingiva; they extend from the cementum of the cervix of the tooth into the free gingiva and attached gingiva.
What is the function of circumferential fibers?
Circumferential fibres encircle the neck of each tooth to form a band within the marginal gingiva. Transseptal fibres run from the cementum of one tooth and insert into that of the adjacent tooth by crossing the interdental septum [23].
What is Transseptal ligament?
Transseptal fibers (H) extend over the alveolar bone crest and are embedded in the cementum of adjacent teeth where they form an interdental ligament. These fibers work to keep the teeth aligned. These fibers may be considered as belonging to the gingival tissue as they do not have an osseous attachment.
What is Dentogingival unit?
The dentogingival unit (DGU) is the anatomical complex formed by the gingival membrane, gingival sulcus, junctional epithelium and connective tissue insertion, also known as the ìbiological spaceî. It is very important, and its invasion may cause the collapse and apical migration of the fixation apparatus.
What are Supracrestal fibers?
Supracrestal fiberotomy is a surgical technique that divides the free gingival and transseptal fibers around rotated teeth that have been corrected orthodontically.
What is Dentogingival Junction?
The dentogingival junction is the junction between the tooth surface and the gingival tissue. Together, the sulcular epithelium and junctional epithelium form the dentogingival junctional tissue.
What is the function of alveolar bone?
Alveolar bone is that part of the maxilla and mandible which supports the teeth by forming the “other” attachment for fibres of the periodontal ligament (Fig. 1.148).
What is alveolar crest?
The alveolar crest is the most cervical rim found in the alveolar bone proper. When it is healthy, the alveolar crest is slightly apical to the cementoenamel junction (CEJ) by about 1.5-2 mm. The alveolar crests of the adjacent teeth are also uniform in height along the jaw when they are healthy.
