Closed Sinus Lift

A surgical technique to increase bone height in the upper jaw. Unlike the "Open" (Lateral Window) technique, the sinus floor is lifted through the hole drilled for the dental implant.

Why It Matters

It is less invasive than an open lift, causing less swelling and faster recovery. However, it is only possible if you still have 4–6mm of natural bone remaining. If you have less, an open lift is required.

Clinical Details

• Osteotome Technique: Instruments are used to gently tap the sinus floor upward, creating a space that is filled with bone graft material.
• Simultaneous Placement: The implant is usually placed immediately during the same surgery.
