The supporting alveolar bone consists of both cortical (compact) bone and trabecular bone. The cortical bone consists of plates on the facial and lingual surfaces of the alveolar bone. These cortical plates are usually about 1.5 to 3 mm thick over posterior teeth, but the thickness is highly variable around anterior teeth. [14] The trabecular ...
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 ...
The PDL is a part of the periodontium that provides for the attachment of the teeth to the surrounding alveolar bone by way of the cementum. PDL fibres also provide a role in load transfer between the teeth and alveolar bone. (PDL fibers absorb and transmit forces between teeth and alveolar bone.
A study on rats suggests that the three-dimensional structure of Sharpey's fibres intensifies the continuity between the periodontal ligament fibre and the alveolar bone (tooth socket), and acts as a buffer medium against stress. Sharpey's fibres in the primary acellular cementum are mineralized fully; those in cellular cementum and bone are ...
Alveolar bone proper; Each of these components is distinct in location, architecture, and biochemical properties, which adapt during the life of the structure. For example, as teeth respond to forces or migrate medially, bone resorbs on the pressure side and is added on the tension side. Cementum similarly adapts to wear on the occlusal ...
Like any other bone in the human body, alveolar bone is modified throughout life. Osteoblasts create bone and osteoclasts destroy it, especially if force is placed on a tooth. [ 38 ] As is the case when movement of teeth is attempted through orthodontics using bands, wires, or appliances, an area of bone under compressive force from a tooth ...
Cementoblasts form the cementum of a tooth. Osteoblasts give rise to the alveolar bone around the roots of teeth. Fibroblasts develop the periodontal ligaments which connect teeth to the alveolar bone through cementum. [4] Tooth development is commonly divided into the following stages: the bud stage, the cap, the bell, and finally maturation.
Proteases, which is produced by the reduced enamel epithelium, results in a path of least resistance as it promotes the breakdown of connective tissue. When stimulating alveolar bone growth at the base of the crypt, expression of the bone morphogenetic protein-6 in the dental follicle may also be necessary.
