A NOVEL TECHNIQUE TO CLOSE LARGE PERFORATION OF SINUS MEMBRANE

Maxillary sinus floor elevation is generally accepted as a regenerative procedure to facilitate dental implants placement in the posterior atrophic maxilla. Although the sinus lift procedure is relatively safe, some potential problems could be occur. The most prevalent intraoperative complication is perforation of sinus membrane, which can lead to graft infection and early failure. The Aim of this work. Is to present a new technique to repair large perforation of sinus membrane. This case report. Is focused on a 10 mm perforation of sinus membrane occurred during preparation of the sinus window. The obliteration of the perforation was obtained by means of suturing sinus membrane with a resorbable material to the bone directly lateral to the osteotomy site. Sinus augmentation procedure could complete and the insertion of a graft was permitted.
