Comparação clínica do piezoelétrico com rotatórios convencionais para o levantamento do seio maxilar: revisão de literatura.

Abstract

Maxillary sinus lift surgery is one of the main alternatives for implant installation in the region of molars and upper premolars in patients with insufficient amount of bone. This procedure had only been performed with conventional rotary instrument and has as main complication the rupture of Schneider's membrane. With the advancement of the technology in odontoly, a system has emerged that promises to cut only the mineralized tissue, preserving soft tissues such as nerves, vessels and even the Schneiderian membrane. In this study, we revised the literature in order to make a comparative analysis of the use of the piezoelectric apparatus with conventional rotary instruments. To do so, a search was made for scientific articles to clarify the issue addressed published between 2007 and 2018 and accessed in the PubMed (MedLine) database. Complete scientific articles on "piezosurgery and / or maxillary sinus lift" were used. We found 1259 articles of which 19 were selected. According to the review, the results were favorable to the use of the piezoelectric system for the maxillary sinus lift procedure. The piezoelectric device has advantages such as better visibility of the surgical field, decreased bleeding, lower bone temperature during operation, lower membrane perforation rate, longer transoperative period, greater speed of bone regeneration, reduction in soft tissue damage, decrease of stress for the patient during the surgery, besides minor edema and postoperative pain. For the observed aspects, it can be concluded that the use of the piezoelectric device has favorable results for the maxillary sinus lift procedure.
