A new classification has been proposed to classify gingival and palatal recessions. The new classification system gives a comprehensive depiction of recession defect that can be used to include cases that cannot be classified according to earlier classifications. A separate classification system for palatal recessions (PR) is also proposed.
Generalized bone loss occurs most frequently as horizontal bone loss. [2] Horizontal bone loss manifests as a somewhat even degree of bone resorption so that the height of the bone in relation to the teeth has been uniformly decreased, as indicated in the radiograph to the rig defects occur adjacent to a tooth and usually in the form of a triangular area of missing bone, known as triangulation.
Based on positive clinical results of regeneration in periodontology research in the 1980s, research began to focus on the potential for re-building alveolar bone defects using guided bone regeneration. The theory of Guided tissue regeneration has been challenged in dentistry. The GBR principle was first examined by Dahlin et al. in 1988 on rats.
The alveolar process is also called the alveolar bone or alveolar ridge. [3] In phonetics , the term refers more specifically to the ridges on the inside of the mouth which can be felt with the tongue , either on roof of the mouth between the upper teeth and the hard palate or on the bottom of the mouth behind the lower teeth.
A buccal exostosis is an exostosis (bone prominence) on the buccal surface (cheek side) of the alveolar ridge of the maxilla or mandible.More commonly seen in the maxilla than the mandible, buccal exostoses are considered to be site specific. [2]
Congenital Epulis is most commonly seen in neonates, with a mass developing from the gingiva and spreading over the maxillary alveolar ridge, generally near the lateral incisors or canine region. [8] It usually tends to grow on the anterior alveolar ridge of newborns, more on the maxilla than on the mandible with a ratio of 3:1. [7]
Gingival (alveolar) cysts of infants are mostly found in groups, but are frequently found as single nodules. They are present on the alveolar ridges. They are formed from fragments of dental lamina that remains within the alveolar ridge mucosa during tooth formation ( odontogenesis ).
Also the alveolar ridge (the gum where the teeth erupt up from, or if missing, where they used to be) and the hard palate (roof of the mouth). The most common are fibrous nodules called fibroepithelial polyps and epulides. Other hyperplastic reactive hyperplastic lesions include those associated with dentures, and papillomas.
