Closed Sinus Lift and Insertion of Implants – How is it done?


The maxillary sinus is an anatomical cavity above the posterior teeth of the upper jaw. It is possible to see an edentulous ridge after extractions are done. The bone is absorbed and ample height for affixing implants is missing. In order to increase the quantity of bone, we can push the sinus upward and place artificial bone (packing material) into the newly-cleared space, which will be replaced (by the body) with the individual’s own bone material within a few months.
In order to insert the packing material into the sinus, we need to create small holes which, after they are widened, will allow new bone to be passed through. The work is performed under local anesthesia, is very exacting, sophisticated and does not hurt at all.

Stage 1: Initial drilling with a small diameter of 2 mm until the base of the sinus bone.

Stage 2: In the space created, convex packed bone with an exact diameter is inserted. With light pressure, the dentist creates a “crack” in the floor of the sinus space. The surgeon will then be able to lift the soft tissues of the sinus (shown in pink in the illustration) without worrying about damaging them.
By repeating the same action, the sinus is packed until the desired height is reached and the implant is inserted. Now, the implant supports the ceiling of the sinus and more bone and more implants can be inserted.
After the implants are inserted, a waiting period of 4-7 months begins, during which native bone will grow from within the packing material and will connect to the implants. The waiting period is determined by the blood supply to the area, the amount of material inserted and personal characteristics of the patient.
After the waiting period, the implants have attached to the bone, and rehabilitation can be performed. At the beginning, gradual loading of the implants is preferable.


Sinus Lift – Risks and Side Effects

Sinus lift treatments have a very high success rate, but as in any surgical procedure, there are side effects. Smoking and blowing the nose should be completely avoided because of the danger of tearing the membrane, of pushing out the implanted bone substitute and of infection. Individuals suffering from chronic sinusitis and imbalanced diabetes should refrain from having a sinus lift.
