Techniques for Reparation of Perforations of the Maxillary Sinus Membrane: Article Review

ABSTRACT

floor elevation is a predictable and standard procedure for the treatment of the posterior maxilla before insertion of dental implants. Although overall complication rates are low, complications can occur including sinus membrane perforation, infection of sinus, swelling and hemorrhage. The most common complication is membrane perforation. Recently, various techniques and materials for repair of perforation to the sinus membrane have been proposed. The purpose of this article is to report on various techniques and materials that can be used for repair of perforations to the sinus membrane. The search protocol used was the following electronic database Pubmed, with a time limit from 1998 to 2009. The key words such as 'sinus lift', 'sinus augmentation', 'sinus floor elevation', 'sinus graft', 'sinus perforation', 'repair of sinus perforation' and 'repair of sinus membrane' were used, alone and in combination, when searching the database. Various techniques have been proposed to manage of perforation of sinus membranes. These include that the use of collagen membranes, demineralized freeze-dried human lamellar bone sheets, processed human allografts, lamella bone, buccal fat pads and suturing. Implant success rate ranges from 69.9% to 98.9%.
