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.
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]
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]
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 ...
Surgical planning is the preoperative method of pre-visualising a surgical intervention, in order to predefine the surgical steps and furthermore the bone segment navigation in the context of computer-assisted surgery. [1] The surgical planning is most important in neurosurgery and oral and maxillofacial surgery.
Preoperative fasting is the practice of a surgical patient abstaining from eating or drinking ("nothing by mouth") for some time before having an operation.This is intended to prevent stomach contents from getting into the windpipe and lungs (known as a pulmonary aspiration) while the patient is under general anesthesia.

[1] In this procedure, the bony edges of the alveolar ridge and its surrounding structures is made smooth, redesigned or recontoured so that a well-fitting, comfortable, and ...
