SYNONYMS: KENNEDY BAR, SPLIT LINGUAL BAR, DOUBLE LINGUAL BAR
1. Situations where the major connector must contact the natural teeth to provide bracing and indirect retention and there are open cervical embrasures which contraindicate the use of a lingual plate. There must be adequate space for the lingual bar portion of the major connector. Continue reading
If the level of the healing ridge is too far corbnal for an esthetic pontic, the anatomical topography of the site must be determined by needle probing under local anesthesia. If there is a thickness of 3 or 4 mm of soft tissue above the alveolus in the center of the ridge, it is necessary only to perform soft tissue gingivoplasty, developing an anatomical configuration compatible with the two adjacent teeth. This is easily accomplished with a rotary diamond instrument. A 1 mm concavity for the base of the pontic, further apical to the maximal curvature of the adjacent marginal gingiva, is developed. To fit into this area, the temporary pontic is relined with self-curing acrylic, trimmed, and polished, allowing the tissue to heal around this ovate form. Continue reading
Desquamative gingivitis is a cutaneous condition characterized by diffuse gingival erythema with varying degrees of mucosal sloughing and erosion.
A band of red atrophic or eroded mucosa affecting the attached gingiva is known as dequamative gingivitis. Unlike plaque-induced inflammation it is a dusky red colour and extends beyond the marginal gingiva, often to the full width of the attached gingiva and sometimes onto the alveolar mucosa. DG is more common in middle-aged to elderly females, is painful, affects the buccal/labial gingiva predominantly. Some reserve the term for cases where the epithelium blisters or peels while others use it whenever the characteristic red appearance is present. (Edward W. Odell, 2010) Continue reading
