What is Sinus Lift?

Sinus lift is a specialized surgical procedure used when the upper jaw does not have sufficient bone support for dental implant placement. This procedure involves lifting the sinus membrane and placing a bone graft underneath it, with the aim of increasing the bone height, making the safe placement of implants possible.

In some cases, the sinus lift and implant placement can be done simultaneously, while in others, a period of time is required for the complete integration of the bone graft before the implant is placed.

When is it needed?

The procedure is necessary when:

There is insufficient bone height for the placement of dental implants due to natural resorption after tooth loss, or because the sinus has expanded downward, or due to a combination of these factors.

Sinus Lift Procedure

• Local anesthesia of the area.
• Incision in the gums and access to the bone of the upper jaw.
• Creation of a small "window" in the bone to expose the sinus membrane (Schneiderian membrane).
• Lifting of the membrane without rupture.
• Placement of the bone graft into the newly created space.
• Suturing of the tissues.

In some cases, if sufficient stability is present, simultaneous implant placement may be performed.

Types of Sinus Lift

• Closed sinus lift

It is performed through the implant hole, without an external opening in the bone. Suitable for cases requiring a small increase in bone height.

• Open sinus lift

A window is created on the lateral wall of the sinus. Suitable for cases requiring a larger increase in bone height.

Conclusion

Sinus lift is a specialized surgical technique applied to create sufficient bone height in the upper jaw, allowing for the safe and successful placement of dental implants.

With modern techniques (CBCT, preoperative planning, high-quality biomaterials, etc.), the procedure is now highly predictable, especially in the open technique, where there is direct control over the lifting of the membrane. Experience is required to minimize complications (e.g., membrane rupture) and to manage them properly if they occur.
