Surgical intervention on the patient can be done for several reasons. The most common is tooth extraction in cases where the teeth cannot be maintained, due to extensive decay, fracture or loss of bone support. However, this type of intervention can also be done in cases such as e nucleation of cysts in the maxillary bones, excision of lesions, frectonomy, exposure of teeth for treatments, placement of implants, drainage of abscesses or oral tissue biopsies.
