This review analyzes articles published on the presence of septa in maxillary sinuses. An automated search was conducted on PubMed using different key words. This search resulted in 11 papers in which the presence of antral septa was assessed. These septa are barriers of cortical bone that arise from the floor or from the walls of the sinus and may even divide the sinus into two or more cavitie...

PURPOSE The purposes of this study were to assess the dentists' subjective satisfaction with the crestal approach sinus (CAS) kit, a device for maxillary sinus membrane elevation by the crestal approach using a special drilling system and hydraulic pressure, and to summarize the subjective satisfaction of dental implants placed after a sinus lift procedure with the CAS kit. METHODS Thirty den...

The sinus lift techniques had a lot of modifications through the years. In 1960 Boyene published sinuslift with lateral access. In the beginning it was used for achieving an optimal intercrestal distance needed for denture making. But in the 1980 Boyen and James started to place implants in the newly created bone. The wish of patients and dentists for minimalivasive methods lead to the developm...

The present report describes the case of a patient who underwent maxillary sinusitis right after dental implant installation with sinus lifting. Computed tomography scan revealed a dental implant (#16) was protruded inside the right maxillary sinus and confirmed the obstruction of ostium. A symptom remission was gained with the dual approaches combined by functional endoscopic sinus surgery and...

PURPOSE The performance of implant surgery in the posterior maxilla often poses a challenge due to insufficient available bone. Sinus floor elevation was developed to increase the needed vertical height to overcome this problem. However, grafting materials used for the sinus lift technique eventually show resorption. The present study radiographically compared and evaluated the changes in heigh...

_Since its introduction, sinus floor augmentation has generated great interest in the international scientific community and been subject to many changes in procedure. The first documented maxillary sinus augmentations using bone grafts date back to the work of Philip J. Boyne in the 1960s.1 An access osteotomy to elevate the sinus membrane can be performed by a vestibular or a crestal approach...

Insufficient bone quality and quantity in posterior maxilla is a common clinical state, which leads to further prosthetic surgery difficulties. It occurs on account of several causes, most frequently due to the pneumatization of sinus subsequent to the tooth loss and the concomitant excessive alveolar resorption [1]. Depleted alveolar bone is insufficient to host implants of 10 mm in length and...
