Sinus lift surgery can help when patient has insufficient bone support for dental implants. It corrects this problem by raising the sinus floor and developing bone for the placement of dental implants.
There are several techniques that can be used to raise the sinus floor and allow for new bone to develop. The common technique is by making an incision to expose the bone and then a small circle is cut into the bone. The bony piece is then lifted into the sinus cavity, much like a trap door, and the space underneath is filled with bone graft material (many options for the type of material to be used). The incision will be closed and allowed to heal. The bone usually requires 4 to 12 months to develop before implants can be placed. After the implants are placed, an additional healing period is required.
Sinus lift surgery greatly increase your chances for successful dental implants that can last for years to come.
