What is a sinus lift?

A sinus lift is an oral surgery procedure that involves the raising of the level of the sinus in order to gain the space and bone material for the implant installation.

Why is the sinus lift necessary?

In the case of molar or pre-molar loss, the bone in this area becomes gradually disintegrated, i.e. the resorption occurs. Over time, the sinus cavity expands, leaving the unsatisfactory bone level which at that moment forms the barrier between the sinus and oral cavity. By lifting the sinus, we create a favourable situation for implant installation since the connection between the implant and the sinus cavity is contraindicated.

What does the procedure look like?

The procedure is conducted in local anaesthesia and is completely painless for the patient. A surgeon must make an incision and then lift the mucous membrane and access the bone wall of the sinus. After that, a “window” is made on the wall of the sinus, after which the mucous membrane of the sinus is carefully separated and the space between the floor and the mucous membrane of the sinus is created. The created space is filled with artificial bone, and the opening is covered with the membrane, after which the wound is sewn.

Can the implants be installed in the same procedure?

Yes. Implants can be momentarily installed after the sinus lift. Also, the installation can be postponed for a period of four to six months. Whether implantation will be delayed or done in the same procedure depends on the complexity of the case and the surgeon’s assessment.

What is needed before the start of the operation?

The patient must make a 3D image upon which the surgeon performs the analysis and plans the surgical procedure.

Are there any contraindications?

The performance of the sinus lift is contraindicated if the patient suffers from a chronic or an acute sinus inflammation, as well as if the patients has cysts that are localized in the sinus. Patients with poor general health conditions and those who suffer from systematic diseases are also not candidates for such surgical procedure.

What to expect after the intervention?

After an intervention, it is possible to expect the swelling and moderate pain in the area of ​​intervention. The pain can be alleviated by using the cold compresses on the spot for five minutes, with half-hour breaks. If necessary, pain killers can be used. The antibiotic is administered to the patient as a preventative measure and they are advised to avoid excessive physical effort.
