Increasing Bone Volume via Minimally Invasive Methods
The sinus cavities located in the posterior regions of the upper jaw tend to sag downwards over time following tooth loss, leading to resorption of the jawbone. Closed sinus lifting is a “sinus membrane elevation” procedure—involving significantly less surgical incision—that is performed in cases where there is only a minor bone volume deficiency, in order to enable implant placement in this area.
Why is a closed sinus lift performed?
-
Insufficient Vertical Bone: This approach is preferred when the bone height required for the implant to anchor securely is borderline, and only an additional 2–3 millimeters of bone volume is needed.
How does the process work?
In this technique, the gum is not extensively reflected. While preparing the implant site (osteotomy), the sinus membrane is accessed very gently using specialized hand instruments and pushed upward. Bone graft material is added to the resulting space, and the implant is often placed into the site during the same session.
Frequently Asked Questions
Is a closed sinus lift a difficult procedure?
On the contrary, it is a minimally invasive (tissue-sparing) procedure that causes significantly less tissue trauma than the open technique and allows for rapid healing.
Will the sinus procedure affect my breathing?
No. The procedure is performed only in the area between the upper jawbone and the floor of the sinus cavity; it has no direct connection to the respiratory tract and does not affect breathing.
Conclusion
Closed sinus lifting enables the safe and long-lasting application of implant treatment by providing sufficient bone support in the posterior region of the upper jaw.
