Sinus Lift

Sinus Lift at Dental Office in St. John's

What Is A Sinus Lift?

A sinus lift can make implant procedures possible. It allows patients with bone loss in their upper jaw to enjoy the benefits from a long-term solution to their missing or failing teeth using dental implants.

A sinus lift is a surgical procedure that grafts bone to the upper jaw at the position of your molar and premolar teeth. The sinus membrane is gently separated and moved upward, or “lifted”. Bone is then added, in most cases the dental implant can be placed at the same time resulting in an increase in bone volume that anchors the implant.

What Does It Involve?

  • Preparation:
    • To begin with, we will conduct a consultation to discuss your needs, this includes taking dental x-rays and may also require a special type of computed tomography (CT) scan to assess the current condition of your jaw. This scan will allow us to accurately measure the height and width of your existing bone and evaluate the health of your sinus.
    • If you have seasonal allergies, please schedule the procedure when they are not active.
  • Surgical Procedure:
    • Internal Sinus Lift ("Summers"/"Floor Elevation" Technique)
      • Access to the sinus cavity is through the empty tooth socket, where a tooth has been lost or where it has been recently extracted.
      • The bone is then drilled out partially and then the base of the hole is tapped upwards towards the sinus creating the depth required to insert an implant. Bone is syringed into the space.
      • This procedure is usually followed by an implant placement.
    • Lateral Sinus Lift
      • An incision made to the side gum tissue where your back teeth used to be. The tissue is raised, exposing the bone. A small, oval window is opened in the bone. The membrane lining the sinus on the other side of the window separates your sinus from your jaw. This membrane is gently moved up and away from your jaw.
      • Granules of bone-graft material are then paced into the space where the sinus was. The amount of bone used will vary, but usally several millimetres of bone is added above the jaw.
      • Once the bone is in place, the tissue is closed with stitches. Your implants will be laced four to nine months later. This allows time for the grafted material to form new bone. The amount of time depends on the amount of bone needed.
      • Sometimes dentists use proteins called growth factors to help the new bone harden faster. Platelet-rich plasma, which contains the growth factors, is taken from your blood before surgery and mixed with the graft that is placed into your sinus.

Recovery & Follow Up

After the procedure, you may have some swelling in the area. You may bleed from your mouth or nose. Please do not blow your nose or sneeze forcefully. Either one could cause the bone-graft material to move and loosen the stitches.

Your dentist may advise you to use saline sprays to keep the inner lining of your nose wet and prescribe medicine to prevent congestion and inflammation. You may also be given a prescription for pain medicine, an antibiotic and an antimicrobial mouthwash to help prevent infection. Most patients have only a little discomfort after a sinus-lift procedure.

You will see the dentist after 7 to 14 days when an evaluation of the surgical site will be undertaken and have sutures removed if they do not dissolve on their own. You might be asked to return a few more times to ensure the area is healing properly.

After a sinus lift, you need to wait several months for the bony material to harden and integrate with your jaw. Depending on the grafting material used, implants may be placed in four to nine months.

What are the Risks?

Some patients have thin sinus membranes or bumpy sinus floors making the release of the membrane more likely to cause a delay in treatment. The main risk of a sinus lift is that the sinus membrane could tear or develop a hole. If the membrane is torn during the procedure, the dentist will either suture the tear or place a membrane over it. If the repair is not successful, your dentist may stop the procedure and give the hole time to heal.

Your dentist can redo the sinus lift once the membrane has healed. This usually takes a few months. A healed membrane tends to be thicker and stronger, which means a second attempt at a sinus lift is likely to be successful. However, other factors also affect success.

Infection is a risk of any surgical procedure. However, this rarely occurs after sinus lifts. On rare occasions, the existing bone does not integrate with the bony graft material, and the grafted area does not develop a blood supply. If this happens, any implants placed in this area will fail because there is no live bone for them to attach to. If this happens, you can have the sinus lift procedure repeated.

Please Call Us If You Notice The Following:

  • Any swelling or pain gets worse over time (it should decrease after the first two days or so).
  • The bleeding does not stop after one to two days.
  • Bleeding is bright red and continuous (normal bleeding after this procedure oozes slowly and is dark red with possible clots).
  • You think the bony material may have been dislodged after sneezing or blowing your nose.
  • Pain does not decrease over time.
  • You develop a fever.
