REMOÇÃO DE TERCEIRO MOLAR EM SEIO MAXILAR COM USO DE TÉCNICA MINIMAMENTE INVASIVA: RELATO DE CASO.

The maxillary sinus is a pneumatized anatomical structure located bilaterally in the anterior region of the maxilla. The occurrence of displacement of foreign bodies in the maxillary sinus is not a common condition and when present, it is associated with car accidents, fire arm accidents, psychiatric disorders and iatrogenies in surgical procedures. The removal of the foreign body is carried out in order to prevent infections, and the permanence of the foreign body may offer immediate or chronic damage. Access to the maxillary sinus is most commonly performed using the Caldwell-Luc access technique. Thus, the objective of the study is to report a clinical case of surgical removal of a maxillary third molar from the interior of the maxillary sinus using the caldwell-luc access technique, with the aid of a surgical guide in order to conduct a safer and less invasive surgery.
