Sinus-Lift Ways and Types of Sinus Augmentation and Use of Piezo-Surgery Device for Fenestration of Sinus Maxillaries

Maxillary sinus floor augmentation (also termed sinus lift, sinus graft, sinus augmentation or sinus procedure) isa surgical procedure which aims to increase the amount of bone in the posterior maxilla (upper jaw bone), in thearea of the premolar and molar teeth, by lifting the lower Schneiderian membrane (sinus membrane) and placinga bone graft [2].When a tooth is lost the alveolar process begins to remodel. The vacant tooth socket collapses as it heals leavingan edentulous (toothless) area, termed a ridge [3]. This collapse causes a loss in both height and width of thesurrounding bone. In addition, when a maxillary molar or premolar is lost, the floor of the maxillary sinus expands,which further diminishes the thickness of the underlying bone. Overall, this leads to a loss in volume of bone thatis available for implantation of dental implants, which rely on osseointegration (bone integration), to replacemissing teeth [1]. The goal of the sinus lift is to graft extra bone into the maxillary sinus, so more bone is availableto support a dental implant.A Special form of Reconstruction of bone, especially changing the vertical structure of the maxillary Sinus floorin the upper jaw and the establishment of the mucous membranes of Sinusitis purpose of dental implant calledSinuslift [4, 5, 6 & 8]. Distance-maxillary sinus is often so low that an implant can not be included in stable longenough. With the incorporation of bone material or bone grafting, maxillary sinus floor, ‘grow’ and that this levelcan be implanted implants safe. Sinuslift distinguish Extern and Intern [9,10].
