Introduction:It has been discussed about maxillary sinus surgery, with the purpose of placing osseointegrated implants in the posterior maxilla, since it presents unfavorable situations for its implantation.This procedure is indicated when pneumatization of the maxillary sinus is evidenced, bone resorption after extraction and poor quality of the residual bone. Case Report: Patient M.C.S.S.O, sought dental service for oral rehabilitation with dental implants. Computed tomography was requested and from the analysis of the radiographic examination it was confirmed minimum bone thickness and pneumatization of the maxillary sinus, with that, a surgery was proposed to lift the maxillary sinus with the use of alloplastic graft. He recommended the surgical procedure through the piezoelectric technique, because it was less traumatic and the use of L-PRF, in order to allow a tissue repair in a shorter time, rapid formation of bone, tissue and other structures, as well as a satisfactory postoperative for the patient. Final Considerations: It is concluded that the advantages of piezoelectric instruments compared to rotary instruments and that to few disadvantages were irrelevant in the present case, however, a learning curve is needed for the adequate handling of the piezo-surgical instruments.
