Maxillary Sinus Augmentation Using Hydraulic Pressure by Lateral Approach and Simultaneous Implant Placement: Clinicoradiographic Study.

The purpose of this study was to assess clinically and radiographically efficacy of maxillary sinus augmentation using hydraulic pressure in a lateral approach with immediate implant placement. In a total of 10 patients having less than 4 to 6 mm of subantral bone height, lateral approach sinus membrane elevation procedure was performed using hydraulic pressure with the help of a specialized water lift kit followed by grafting and simultaneous implant placement. Cone beam computed tomography analysis was used to assess the change in subantral bone height from baseline to the 6 months postoperatively. Radiographically, subantral bone height increased from 3.86 ± 1.423 mm at baseline to 15.49 ± 2.73 mm at 6 months postoperatively with a gain of 11.63 + 2.63 mm (P < 0.001). Thus, it is concluded that hydraulic pressure may be efficiently used in lateral sinus augmentation procedures along with simultaneous implant placement.
