Densah® Sinus lift in the 4mm Ridge
Patient is missing #3 with significant maxillary sinus pneumatization.
Working depth was 4.2 mm.
No pilot was used to avoid the risk of membrane perforation.
Densah bur1 (2.3 mm) was used in CCW to enter the sinus.
Larger diameters Densah Burs were used with vertical stops and in a consecutive order to create the desired osteotomy width.
At no time densah bur would travel > 3mm beyond the sinus floor.
In this case The working length of the Densah Burs was up to 7mm.
Allograft was used to create an additional membrane lift (>3mm lift)
