Abstract
|
|
|
|
Several methods for sinus lifting have been developed for implant installation on the maxillary posterior edentulous area with an alveolar bony defect. The major complication for sinus lifting is sinus membrane perforation, and the crestal approach technique has drawbacks that make it impossible to directly ascertain membrane perforation. Lately, the hydraulic pressure technique was developed for prevention of sinus membrane perforation as well as to obtain an ideal shape of the bone graft material. For sinus lifting, this method reveals a lower part of the membrane using a specially designed drill that elevates the membrane using hydraulic pressure. This method enables the operator to elevate the sinus membrane and bone graft regularly. In this study, morphologic analysis was performed with computed tomography to evaluate the peri-implant bony shape after sinus lifting with a sinus lift drill using hydraulic pressure.
