Perform the Osteotomy
Takeaways
Osteotomy – Key Points
- Using a physio dispenser, drill with a contra-angle handpiece at a speed ranging between 800-1600 RPM at a high torque and constant saline cooling. The speed depends on the hardness in the drilling area.
- Manual stabilization during the initial socket creation using B.Y.1. is required.
- After the initial drilling, use the consequent B.Y. diamond milling bur.
- Check with the osteotome for a breach of the membrane – if a gap is detected it means there is no breach.
- Every 2 clockwise rotations of the stopper adds 1mm in length. For example – If B.Y. 2 is reached, set the osteotome to 3mm when checking for a breach.
- When there is no gap, and the sinus has been breached, it is time to elevate the membrane.
Scenario A Table
| B.Y. Used | Osteotome Length |
| B.Y.1 | 2mm |
| B.Y.2 | 3mm |
| B.Y.3 | 4mm |
| B.Y.4 | 5mm |
