UNLABELLED 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. ...

Introduction. Sinus lift procedures are a commonly accepted method of bone augmentation in the lateral maxilla with clinically good results. Nevertheless the role of the Schneiderian membrane in the bone-reformation process is discussed controversially. Aim of this study was to prove the key role of the sinus membrane in bone reformation in vivo. Material and Methods. 14 patients were treated w...

This case series study demonstrates the possibility of successful implant rehabilitation without bone augmentation in the atrophic posterior maxilla with cystic lesion in the sinus. Sinus lift without bone graft using the lateral approach was performed. In one patient, the cyst was aspirated and simultaneous implantation under local anesthesia was performed, whereas the other cyst was removed u...

BACKGROUND Various techniques are available for elevating the sinus membrane. The aim of this study is to evaluate three methods of indirect sinus floor elevation regarding elevation heights of 7 mm on the outcomes of membrane perforation, length of perforation, and time required to perform the procedure. METHODS Three different methods for indirect sinus lifting, bone added osteotome sinus f...

A retrospective clinical study of patients who underwent direct sinus lift and implant placement was conducted. Forty-six patients with 58 direct sinus lifts were included and a total of 102 implants were placed. Cigarette consumption was quantified and the level of oral hygiene determined at the time of surgery using a simplified calculus and plaque index. Bone loss and implant success (accord...

A review of maxillary sinus floor elevation as an integral part of restoring the posterior maxilla is discussed. The related anatomy of the area and the current techniques available are reviewed. The classic lateral antrostomy pioneered by Tatum appears to be the most common sinus lift procedure. The more conservative crestal approach, advocated by Summers, provides another effective way of all...

Implant placement becomes complicated when the height and width of the bone is compromised especially in the posterior maxillary region due to the presence of sinus. This case report presents the rehabilitation of the left maxillary premolar region by using indirect sinus lift and ridge splitting followed by immediate implant placement where the bone height and bone width was compromised. It he...

Introduction In the posterior maxillary sextants, insertion of implants of desired length and diameter is often limited by the dimensional alterations of the residual ridge as well as the pneumatization of the maxillary sinus occurring after tooth loss. Transcrestal sinus floor elevation (tSFE) represents a surgical option to vertically enhance the available bone in the posterior maxillary sext...

The aim of this study is to evaluate the efficacy of the application of allogenous bone at the maxillomandibular reconstructions for future rehabilitation with dental implants. The patients were submitted to reconstruction of maxilla, using allogeneic bone grafts, in 3 different techniques: onlay grafts for lateral ridge augmentation, onlay and particulate bone for sinus lift grafting, and part...
