Impacted wisdom teeth are classified by the direction and depth of impaction, the amount of available space for tooth eruption and the amount of soft tissue or bone that covers them. The classification structure allows clinicians to estimate the probabilities of impaction, infections and complications associated with wisdom teeth removal. [31]
A treatment controversy exists about the need for and timing of the removal of disease-free impacted wisdom teeth. Supporters of early removal cite the increasing risks for extraction over time and the costs of monitoring the wisdom teeth. Supporters for retaining wisdom teeth cite the risk and cost of unnecessary surgery.
When extracting lower wisdom teeth, coronectomy is a treatment option involving removing the crown of the lower wisdom tooth, whilst keeping the roots in place in healthy patients. This option is given to patients as an alternative to extraction when the wisdom teeth are in close association with the inferior alveolar nerve , and so used to ...
The lower teeth, and in particular the lower wisdom teeth, can therefore be in close proximity to this nerve. Damage to the inferior alveolar nerve is a risk of lower wisdom tooth removal (and other surgical procedures in the mandible). [20]
Most often, the cause of impaction is inadequate arch length and space in which to erupt. That is the total length of the alveolar arch is smaller than the tooth arch (the combined mesiodistal width of each tooth). The wisdom teeth (third molars) are frequently impacted because they are the last teeth to erupt in the oral cavity.
A panoramic radiograph is a panoramic scanning dental X-ray of the upper and lower jaw.It shows a two-dimensional view of a half-circle from ear to ear. Panoramic radiography is a form of focal plane tomography; thus, images of multiple planes are taken to make up the composite panoramic image, where the maxilla and mandible are in the focal trough and the structures that are superficial and ...
B) Extraction socket of unrestorable upper right first permanent molar. C) Extracted upper right wisdom tooth (FDI:18) immediately transplanted into socket of upper right first permanent molar. D) Transplanted wisdom tooth splinted into position. E & F) Gold shell crown fitted onto transplanted tooth to restore contact with adjacent tooth and ...
A treatment controversy exists about the necessity and timing of the removal of asymptomatic, disease-free impacted wisdom teeth which prevents pericoronitis. Proponents of early extraction cite the cumulative risk for extraction over time, the high probability that wisdom teeth will eventually decay or develop gum disease and costs of ...
