Sinus Lift Surgery - Sinus Augmentation

Why Sinus Lift Surgery is Performed?

A sinus lift surgery is performed when there isn't sufficient bone height in the upper jaw, or the sinuses are excessively near the jaw for dental implants to be put. There are a few purposes behind this:

• Numerous individuals who have lost teeth in their upper jaw — especially the back teeth, or molars — don't have enough bone for implants to be set. Due to the anatomy of the skull, the back of the upper jaw has less bone than the lower jaw.
• The bone may have been lost on account of periodontal (gum) infection.
• Tooth loss may have prompted lost bone. When teeth are gone, bone starts to be resorbed (retained again into the body). If teeth have been absent for quite a while, there regularly isn't sufficient bone left to put implants.
• The maxillary sinus might be excessively near the upper jaw for implants to be put. The shape and the size of the sinus vary from individual to individual. The sinus likewise can grow more prominent as you age.

How is the Diagnosis Made for Sinus Lift Surgery?

• Computerised Tomography (CT) Scan This test provides the doctor with clear, cross-sectional images of internal structures of the body. The size and shape of a sinus, or an abnormality can be detected through this method. The doctor injects the patient with a dye and slides the movable table inside a doughnut-shaped machine.
• Magnetic Resonance Imaging (MRI) An MRI helps in determining the size and location of an abnormality of the sinus. The doctor makes the patient lie on a table, which is then slid into a tunnel-like machine, where magnetic field radio wave pulses scan the patient’s body and create the images. Whether to inject a dye or not is the doctor’s decision.
• Positron Emission Tomography (PET) PET uses a small amount of radioactive materials called radiotracers, a unique camera and a PC to help assess throat and its functions. By studying body changes at the cell level, PET may identify the early onset of sinusitis before it is evident on other imaging tests.
• X-ray A radiologist can tell if sinus abnormality is harmful by the manner in which it shows up on the x-ray.

What happens Amid the Procedure?

Your specialist will cut the gum tissue where your back teeth used to be. The tissue is lifted, thus uncovering the bone. A little, oval window is opened in the bone. The layer covering the sinus on the opposite side of the window isolates your sinus from your jaw. This layer is tenderly pushed up and away from your jaw.

Granules of bone-join material are then pressed into the space where the sinus was. The amount of bone used will vary, yet only a few millimetres of bone is included over the jaw.

Once the bone is set up, the tissue is closed with a suture. The implants will be put four to nine months after the procedure. This permits time for the grafted material to merge with your bone. The amount of time relies upon the type of bone required.

How is Postoperative Care Done?

After the methodology, you may experience swelling in the operated region. You may bleed from your mouth or nose. Try not to clean out your nose or sniffle strongly. Possibly one could make the bone-graft material move, and release the fastens.

Your dental specialist may give you saline sprays to keep the internal coating of your nose hydrated and recommend a liquid to avoid clotting and inflammation. You additionally will be given pain medication, an antibacterial and an antimicrobial mouthwash to help prevent infection. Most patients have just a little pain after a sinus-lift methodology.
