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.
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.
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.
The e-PTFE membrane is sintered with pores of 5 - 20 μm within the framework of the material. The e-PTFE membrane behaves as a barrier to prevent fibroblasts and various connective-tissue cells from entering the bone defect in order to allow the slower moving cells that are osteogenic to repopulate the defect.

Socket preservation or alveolar ridge preservation (ARP) [1] is a procedure to reduce bone loss after tooth extraction to preserve the dental alveolus (tooth socket) in the alveolar bone. A platelet-rich fibrin (PRF) [ 2 ] membrane containing bone growth enhancing elements can be stitched over the wound or a graft material or scaffold is placed ...
Socket preservation or alveolar ridge preservation is a procedure to reduce bone loss after tooth extraction. [ 1 ] [ 2 ] After tooth extraction, the jaw bone has a natural tendency to become narrow , and lose its original shape because the bone quickly resorbs , resulting in 30–60% loss in bone volume in the first six months.

It is a classed as a pseudocyst, [1] since there is no epithelial lining or fluid content. This defect is usually considered with other cysts of the jaws, since it can be mistaken for such on a radiograph. Two classification systems were proposed to categorize Stafne bone cavity based on its depth [2] and content. [3]
The alveolar ridge, the gum line just behind the teeth ; The back of the alveolar ridge (post-alveolar) The hard palate on the roof of the mouth ; The soft palate further back on the roof of the mouth ; The uvula hanging down at the entrance to the throat ; The throat itself, a.k.a. the pharynx
