About open sinus-lifts
How is a traditional sinus lift performed?
Are you concerned with the way you will look and feel after a traditional “open” sinus lift procedure? You should be. The open sinus-lift is highly invasive, cuts a large amount of gum and bone, and is painful.
A traditional open sinus-lift is a highly-invasive surgical procedure that requires the cutting of bone and gum. When bones and gums are cut, you suffer from pain, extensive swelling, and bruising. As a result, patients stay indoors to heal for an average of 7 days, missing work and even avoiding family and friends, until all visible facial trauma subsides.
How is an open sinus-lift surgery performed?
Open sinus-lift surgery is a highly specialized procedure. It requires the know-how of expert dentists known as oral surgeons or periodontists. The surgical procedure itself takes about 1 to 1.5 hours and requires the following steps:
On the day of the sinus-lift surgery
- Cutting the gums:Your surgeon will cut the tissue in the upper gums, raising the tissue and exposing the bone before making an incision, or opening, in the bone.
- Cutting the jaw bone: An opening, known as a “lateral window”, is created in the bone to expose the membrane lining of the sinus that separates your sinus from your jaw. This membrane is pushed up and separated from your jawbone.
- Raising the sinus membrane: The delicate membrane that lines the inside of the sinus is peeled from the sinus floor, using a tool resembling a small spatula. This operation is quite difficult to perform and very often causes the membrane to tear, increasing both surgery time and the likelihood of complications.
- Bone graft insertion: Bone graft material is inserted into the opening. There are several types of graft materials that can be used – your own bone, animal bone, or a synthetic substance.
- Closing: After the bone graft insertion, the tissue is closed by placing a collagen membrane patch and applying a few stitches. The bone graft remains in place for several months until it hardens and bonds with your jaw, which takes between 6 and 9 months.
In the months that follow
1.Implant placement: 6 to 9 months after the procedure described above, your dental implant can be placed in the new bone. The implant is left in place untouched, until it creates a strong bond with the bone. This can take another 3 to 6 months
2.Crown placement: Finally, after more than 12 months, you are ready for the crown, which is your new tooth.
What are the potential problems and complications of open sinus lifts?
During the procedure
The main complication of a sinus lift is the tearing or puncturing of the sinus membrane. If this happens, the surgeon will place a patch over it. If the repair is not successful, your surgeon may stop the procedure and give the hole in the membrane time to heal before continuing. You will be asked to come back after a few months to redo the procedure.
After the procedure
After your sinus lift you will experience pain, discomfort, facial swelling, and bruising. Most people spend several days at home to rest and recuperate before returning to work.
You may bleed from your mouth or nose and you will be requested to avoid blowing your nose forcefully, as it can cause the bone graft material to move, which might loosen the stitches.
