In dental anatomy, the free gingival margin is the interface between the sulcular epithelium and the epithelium of the oral cavity. This interface exists at the most coronal point of the gingiva , otherwise known as the crest of the marginal gingiva.
The marginal gingiva has a more translucent appearance than the attached gingiva, yet has a similar clinical appearance, including pinkness, dullness, and firmness. In contrast, the marginal gingiva lacks the presence of stippling, and the tissue is mobile or free from the underlying tooth surface, as can be demonstrated with a periodontal probe.
The clinical importance of the mucogingival junction is in measuring the width of attached gingiva. [1] Attached gingiva is important because it is bound very tightly to the underlying alveolar bone and provides protection to the mucosa during functional use of the structures of the oral cavity during function, such as chewing.
A free gingival graft is a dental procedure where a small layer of tissue is removed from the palate of the patient's mouth and then relocated to the site of gum recession. It is sutured (stitched) into place and will serve to protect the exposed root as living tissue.
The gingival fibers, (H), extend from the cementum (B) into the attached gingiva. Some fibers extend coronally into the crest of the free gingiva, some horizontally, and still other extend horizontally over the crest of the alveolar bone, (C), and then apically to connect on the facial aspect of the buccal plate of the alveolar bone.
As explained by Arlene Asante, DMD, dentist and owner of First Class Smiles Bethesda, gingivitis is, "a common and mild form of gum disease that causes irritation, redness, and swelling of the ...
A free gingival graft is a type of gingival grafting performed to correct acquired deficiencies of the gum tissue around teeth or dental implants.Besides autologous tissues, xenogeneic collagen matrices are using for gingival augmentation after dental implantation. [1]
The junctional epithelium, a nonkeratinized stratified squamous epithelium, [1] lies immediately apical to the sulcular epithelium, which lines the gingival sulcus from the base to the free gingival margin, where it interfaces with the epithelium of the oral cavity.
