Terminology and Structure - Alveolar refers to the cavities of the tooth sockets, known as dental alveoli. - Alveolar process is also called alveolar bone and alveolar ridge. - The curved portion is referred to as the alveolar arch. - Alveolar crest describes the extreme rim of the bone nearest to the crowns of the teeth. - The portion of alveolar bone between two adjacent teeth is known as the interdental septum. - The alveolar process is a ridge on the inferior surface of the maxilla and on the superior surface of the mandible. - It holds the teeth and is encased by gums as part of the oral cavity. - The alveolar process comprises cells, nerves, blood vessels, lymphatic vessels, and periosteum. - The alveolar process proper encases the tooth sockets and contains a lining of compact bone called the lamina dura. - The supporting alveolar bone consists of both cortical (compact) bone and trabecular bone.

Composition and Clinical significance - Alveolar bone is 67% inorganic material, mainly calcium and phosphate. - The remaining 33% is organic material, consisting of collagen (mostly type I) and non-collagenous protein. - The cellular component of bone consists of osteoblasts, osteocytes, and osteoclasts. - Alveolar bone loss is closely associated with periodontal disease, which is inflammation of the gums. - Resorption, carried out by osteoclasts, leads to bone loss in the alveolar process. - Inflammation and cytokinesis may inhibit bone formation, resulting in a net loss of alveolar bone. - Developmental disturbances such as anodontia can affect the development of the alveolar processes. - Extraction of a tooth can cause alveolar osteitis, also known as dry socket, and loss of alveolar bone.

Pathology and Bone Grafting - Alveolar bone loss can result in a loss of height of the lower third of the face. - Alveolar bone density affects the route of dental infection and the efficacy of local anaesthesia. - Chronic periodontal disease can cause localised bone loss. - The radiographic integrity of the lamina dura is important in detecting pathological lesions. - Alveolar bone grafting is performed to reconstruct alveolar defects, particularly in cleft lip and cleft palate patients. - Primary bone grafting is abandoned in most cleft lip and palate centers worldwide due to growth disturbances. - The vomero-premaxillary suture technique inhibits maxillary growth. - Secondary bone grafting stabilizes the maxillary arch and allows tooth eruption through the grafted bone. - It enhances conditions for prosthodontic treatment and orthodontic closure of the cleft region. - Secondary bone grafting can also augment the alar base of the nose for facial symmetry. - Congenital epulis is a rare, benign mesenchymal tumor usually present at birth. - It appears as pedunculated, reddish pink masses on the alveolar ridge. - More common on the maxillary alveolar ridge and in females. - Prenatal diagnosis is now possible at 26 weeks. - Surgical excision is the treatment for congenital epulis.

Alveolar Ridge Preservation and Dental Implants - Preservation of the alveolar ridge improves the success rate of dental treatments. - Grafting materials can reduce dimensional changes after tooth extraction. - Different materials have varying efficacy in maintaining the alveolar ridge. - Xenograft and allogenic grafting materials surrounded by collagen membranes are ideal for horizontal preservation. - Bio-Oss, Bio-Oss Coll, and L-PRF are reliable options for ridge augmentation. - Dental implants replace missing teeth and require sufficient alveolar bone support. - Factors like bone resorption, periodontal disease, and systemic diseases contribute to alveolar bone loss. - Implant failure is more common in the front portion of the upper jaw. - The alveolar bone in the upper jaw has thinner cortical plate and lower bone density. - Research focuses on new techniques and biomaterials for maintaining or stimulating alveolar bone growth.

Articulation and Cultural Significance - Alveolar consonants are made with the tongue touching or reaching for the alveolar ridge. - Examples in English include t, d, s, z, n, l. - Some accents, like the New York accent, pronounce [t] and [d] at the back of the top teeth. - In many languages, consonants are articulated with the tongue touching or close to the alveolar ridge. - Alveolar plosives (t, d) and alveolar fricatives (s, ʃ, z, ʒ) are common in many languages. - The alveolar process was used as physical evidence to confirm Adolf Hitler's death in 1945. - Eva Braun's autopsy report mentioned the missing alveolar process in her charred maxilla. - The alveolar process plays a role in dental identification and forensic investigations. - The alveolar process is located on the mandible and maxilla. - It forms the superior area of the mandibular alveolar process. - The maxillary alveolar process is located on the inferior surface of the maxilla. - The alveolar processes are covered by gums in the oral cavity. - The roots of the teeth, gums, and alveolar bone are closely related. - There are 3D animations available that show the placement of teeth in the human skull. - The alveolar process of archaic humans, such as Homo heidelbergensis, can be eroded. - Erosion of the alveolar process can affect the stability of teeth. - The erosion of the alveolar process can be caused by various factors, including periodontal disease.
