Densah Sinus Lift with Navident system
Posted on 04.20.2019 02:29 AM By Joey Chen In Implants
48 yo female presented with missing maxillary right first molar. The residual bone height was 5 ~ 5.5 mm. Sinus floor elevation was performed with the Densah burs and the Navident dynamic navigation system. The Navident system was used to make osteotomies in the ideal position and stay 1 mm short of the sinus floor. The Densah burs were then used sequentially to elevate the sinus floor apically and laterally. An 4.2 x 9 mm implant was placed simultaneously with > 35 Ncm insertion torque.

This is fantastic! Dynamic navigation makes this procedure as safe as possible.
Thank you for sharing!

How would you do a similar lift with 1-2mm residual crestal bone? Thank you for the presentation!

I would use the Densah burs to make a small opening in the sinus floor. Then place a small amount of bone graft at the opening. Set the burs in counter-clockwise and 30 rpm, and slowly push the graft materials into the sinus. The burs will push the graft not only apically but also laterally. This step needs to be repeated several times until the desired elevation amount is reached. Initially the burs should only go pass the sinus floor 3 mm, and as more graft is placed into the sinus, I would insert the burs a little more each time till I reach the depth of my desired implant length. If I have 2 mm of residual bone, I may still be able to achieve decent implant primary stability so I can place my implant simultaneously. But if I only have 1 mm of bone, then I don't think I can do sinus floor elevation and place implants at the same time.

Great Job Joey👏👏👏👏. Looks like you’re ready for Navigation SPOT Drilling Protocol. Show us the way my friend.
