The third molar, commonly called wisdom tooth, is the most posterior of the three molars in each quadrant of the human dentition. The age at which wisdom teeth come through ( erupt ) is variable, [ 1 ] but this generally occurs between late teens and early twenties. [ 2 ]
This system includes a horizontal and vertical component to classify the location of third molars (predominately applicable to lower third molars): the third molar's relationship to the level of the teeth already in the mouth, being the vertical or x-component and to the anterior border of the ramus being the horizontal or y-component.

There is evidence that use of antibiotics before and/or after impacted wisdom tooth extraction reduces the risk of infections by 66%, and lowers incidence of dry socket by one third. For every 19 people who are treated with an antibiotic following impacted wisdom tooth removal, one infection is prevented. [19]
Orthognathic surgery (/ ˌ ɔːr θ ə ɡ ˈ n æ θ ɪ k /), also known as corrective jaw surgery or simply jaw surgery, is surgery designed to correct conditions of the jaw and lower face related to structure, growth, airway issues including sleep apnea, TMJ disorders, malocclusion problems primarily arising from skeletal disharmonies, and other orthodontic dental bite problems that cannot ...
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 ...
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. Mandibular third molars are more commonly impacted than their maxillary counterparts.
Buccal nerve block (long buccal nerve block) is indicated for procedures involving the mucosa adjacent to the posterior molar teeth, such as the placement of a rubber dam clamp. The injection site is distal and buccal to the third molar, with the needle penetrating 1-2mm as the nerve lies directly below the mucosa. [ 5 ]
Judicious reproximation disking of primary teeth with no tooth extraction is an occasional option. This decision depends on the careful tooth size-arch length evaluation. The amount of crowding, the arch length requirements, whether they are symmetric, and the state of health of the investing tissues are factors that continually impact the ...
