In periodontal disease, not only does the bone that supports the teeth, known as alveolar bone, reduce in height in relation to the teeth, but the morphology of the remaining alveolar bone is altered. [1] The bone destruction patterns that occur as a result of periodontal disease generally take on characteristic forms.
Although the alveolar process is composed of compact bone, it may be called the cribriform plate because it contains numerous openings known as Volkmann's canals, which allow blood vessels to pass between the alveolar bone and the PDL. The alveolar bone proper is also called bundle bone because Sharpey's fibres, part of the PDL, are inserted ...
Alveolar osteitis usually occurs where the blood clot fails to form or is lost from the socket (i.e., the defect left in the gum when a tooth is taken out). This leaves an empty socket where bone is exposed to the oral cavity, causing a localized alveolar osteitis limited to the lamina dura (i.e., the bone which lines the socket). This specific ...
alveolar bone, or the bony sockets into which the teeth are anchored, and; periodontal ligaments (PDLs), which are the connective tissue fibers that run between the cementum and the alveolar bone. This X-ray film displays two lone-standing mandibular teeth, the lower left first premolar and canine, exhibiting severe bone loss of 30–50%.
An alveolar cleft is a failure of the premaxilla to fuse with the upper jaw leaving a defect in the bone. It is common in people with cleft palate and is also associated with holes between the mouth and the nose that affects speech, and allows fluid to move into the nose when eating and drinking.

To complete the diagnosis, the extent of the disease must be assessed. This is defined as: mild (1-2mm), moderate (3-4mm) or severe (≥ 5mm) depending on the amount of attachment loss present. Radiographs such as bitewings, intra-oral periapicals or a panoramic radiograph can be taken to help assess the bone loss and aid in diagnosis.
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.
There may be an appearance of "arc-shaped loss of alveolar bone extending from the distal surface of the second premolar to the mesial surface of the second molar". [38] In GAP, generalized bone destruction is present that ranges from mild crestal bone resorption to severe alveolar bone destruction, depending on the severity of the disease. [38]
