The periodontal ligament attaches the tooth root to alveolar bone, and it serves to absorb and resist the forces of occlusion on the tooth. It consists of collagenous fiber bundles containing hundreds or thousands of individual collagen fibrils (Fig. ). The articulation between the periodontal ligament and the bone at the base of the tooth is what type of joint? the articulation between the periodontal ligament and the bone at the base of the tooth is what type of joint? symphysis gomphosis syndesmosis synostosis suture. The periodontic ligament has assorted maps, in peculiar tooth support and eruption, related to its structurally complex is shown through its extended development trusting on the timing of events such as dentine formation so that the cells of the dental follicle can distinguish into those cells required to bring forth the periodontic organisation of these cells.

Application of large forces results in necrosis of PDL and alveolar bone on the pressure side and movement of the tooth will occur after the necrotic bone has been resorbed by osteoclasts located on its endosteal surface.

- mm at 32 to 50 years of age. - mm at 51 to 67 years 1. width of periodontal ligament decreases as age advances 2. Extent of alveolar bone loss can best be determined by radiographs.
X-rays provides important info concerning supporting bone that cannot be clinically seen. Crestal changes, bone loss, changes in width and shape of periodontal ligament space and furcation involvements can be seen on an x-ray.
When the cementum and bone are forming, ends of bundles of the periodontal ligament fibers become entrapped in the forming hard only exceptions are fibers around the cervix of the tooth that attach to either the gingiva or the adjacent tooth.

Periodontics is the dental specialty that relates specifically to the care and maintenance of FMA: Periodontal disease, including gingivitis and periodonti-tis, is a chronic immune inflammatory response associat-ed with genetic and environmental factors Periodontitis is characterized by an inflammatory destruction of the supporting apparatus of the tooth (periodontal ligament, cementum, and alveolar bone), which results in gradualFile Size: KB.

Overview of periodontal ligament structure The periodontal ligament is the connective tissue layer between the cementum covering of the tooth root and the alveolar bone. The ligament forms a link between the tooth and the bone, thus providing support, protection and sensory input for the masticatory system 1.

Helper function is the main function of the periodontal ligament, to secure the tooth, his bony socket and isolate the tooth from the wall socket, so the root does not conflict with the bone during chewing.

Tooth implantation provides important phylogenetic and functional information about the dentitions of amniotes. Traditionally, only mammals and crocodilians have been considered truly thecodont, because their tooth roots are coated in layers of cementum for anchorage of the periodontal ligament, which is in turn attached to the bone lining the alveolus, the alveolar bone.
The two non-calcified (soft) connective tissues are the periodontal ligament (PDL), which fills the periodontal space between the root and the socket wall, and the lamina propria of the gingiva.
By convention the boundary between the two is a horizontal line drawn at the level of the alveolar crest. Fig. Principal fiber groups of the periodontal ligament.
All fibers listed in the buccolingual plane are also present in the mesiodistal plane. The transseptal fiber group number 5, however, is seen only in mesiodistal plane, as these fibers are attached tooth to tooth.
All other principal fibers are attached tooth to the gingiva or alveolar bone. (1 of 16) Formation of Periodontal Ligament. During tooth development, the dental follicle embraces the dental organ and the mesenchyme (A) gives rise to fibroblasts and aries (B) and nerves invade the region by the time the dental organ is forming the crown of the stage of development is seen here and it remains little changed in appearance until the tooth starts.
Study of tension in the periodontal ligament using the finite elements method Orthodontic movement is process of transformation of a physical stimulation into a force applied to a tooth, with a biological response identified as bone remodelling.
Although it is possible to measure the force applied on a tooth, its distribution around the root. The periodontal ligament, commonly abbreviated as the PDL, is a group of specialized connective tissue fibers that essentially attach a tooth to the alveolar bone within which it sits.

The periodontal ligament has been shown to possess the ability to regenerate both new cementum and alveolar bone as well as a self-regenerative capacity; however, the source of cementoblasts and osteoblasts is not still clear.
