Background: Implant placement in the posterior maxilla is problematic procedure, not only due to inferior properties of bone but also due to loss of vertical bone height, which happens after extraction of posterior teeth. When the required additional height is few millimeters, indirect transcrestal sinus lifting is recommended. Aim: The aim of this study is to evaluate Densah bur versus Magnetic mallet in transcrestal sinus lifting procedure in edentulous molar and premolar maxillary region.

| Electrical Mallet | Procedure | The osteotome will be directly attached and pushed by magnetic mallet and a shock wave will be pushed on their tip. The electrical mallet will be imparted to osteotomes a longitudinal movement along a central axis moving up and down toward pilot bone hole providing a driving mechanism of longitudinal movements. Then the sinus lift instruments (Sweden and Martina) will be used to slowly lift the sinus. After that implant will be placed with the help of implant drilling device. |

| Densah bur | Procedure | The implant motor will be adjusted on reverse-densifying mode with 800 to 1200 rpm. According to the desired implant dimension, it will be started with the smallest densah bur. The first densah bur will advanced in densifying mode with bouncing motion in and out movement with copious irrigation until. |
