Maxillary Sinus Left
Conditions
Brief summary
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.
Interventions
PROCEDUREElectrical Mallet
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.
PROCEDUREDensah bur
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in pain socres | 3rd day, 1 week and 10 days | pain will be examined using visual analogue scale (VAS) 0 means no pain 10 means extreme pain |
| change in implant stability | baseline and 4 months | will be measured by the Resonance Frequency Analysis using osstel |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| change in implant protrusion length | baseline and 4 months | Immediate post- operative CBCT (T1) will be done to measure the implant protrusion length (IPL) which is the length of the implant extending into the maxillary sinus. |
| change in bone density | baseline and 4 months | it will be measured by CBCT |
| change in prescence of complications | 3rd day, 1 week and 10 days | patients will be followed up to assess the occurence of any clincial complications |
