How is the periodontal ligament removed?

Instead of the Hollywood-stylized pull most often seen in movies, your dentist will work slowly to tear at the periodontal ligament to loosen the tooth enough, using smooth, steady pressure with the forceps until the tooth can be removed.

What are the Fibres of periodontal ligament?

The PDL consists of principal fibers, loose connective tissue, blast and clast cells, oxytalan fibers and Cell Rest of Malassez. The primary principal fiber group is the alveolodental ligament, which consists of five different fiber subgroups.

What do periodontal Fibres do?

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 fibres absorb and transmit forces between teeth and alveolar bone.

Should the periodontal ligament be removed?

Periodontal Ligament When you bite down and chew, the PDL protects the tooth from shattering by compressing a fraction of a millimeter like a spring. It is standard of care for a traditional oral surgeon to assume that the periodontal ligament adheres to the tooth and is therefore always removed during an extraction.

Is the periodontal ligament a connective tissue fiber?

[edit on Wikidata] 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.

How does mechanical force control periodontal ligament remodeling?

Periodontal ligament (PDL), as a mechanical connection between the alveolar bone and tooth, plays a pivotal role in force-induced orthodontic tooth movement (OTM). However, how mechanical force controls remodeling of PDL collagenous extracellular matrix (ECM) is largely unknown.

What happens if a periodontal ligament is not removed?

It surrounds the teeth and works as a connector between the alveolar bone and the cementum. If the ligament is not properly removed after a tooth extraction, it can become an obstacle for the cells that form the bone to act on the alveolus in the optimal way. If this happens, it could cause cavitations in the future.

How does the periodontal ligament support the alveolar bone?

Outer layers of blood supply in PDL may help in mechanical suspension and support of the tooth while inner layers of blood vessels supply surrounding PDL tissues. There are progenitor cells in the periodontal ligament that can differentiate into osteoblasts for the physiological maintenance of alveolar bone and, most likely, for its repair as well.
