Bilateral maxillary sinus lift by two different techniques with concomitant installation the implants: case report

Abstract

This article aims to demonstrate, through a clinical case report, the bilateral maxillary sinus lifting approach by two different techniques, a traumatic one through the side window and an atraumatic one through the bone crest, associated with the installation of osseointegrated implants. A 75-year-old female patient sought care at the clinic of the Extension Course in Implantology at an university of Rio de Janeiro with pain in upper molars. After anamnesis, clinical examination and analysis of computed tomography, extensive furcation lesion was observed in elements 16 and 26, with extraction and rehabilitation with oseeointegrated implants being indicated. Also, due to the low subantral bone height, the lifting of the bilateral maxillary sinus was included in the treatment plan. On the right side, the Summers technique was performed and on the left side the side window technique associated with the use of particulate synthetic biomaterial and resorbable collagen membrane. The panoramic radiograph of post-surgical control demonstrated the success of both techniques with an adequate anatomical relationship of the graft and both implants to the recipient bed. Thus, maxillary sinus elevation surgery with the concomitant installation of implants proved to be a safe procedure of good predictability and low rate of complications.
