What is a sinus lift?

A sinus lift, also called sinus augmentation, is a procedure designed to create more bone in the back part of the upper jaw – where the premolars and molars lie – for the placement of implants. This happens when there is not enough bone height in the upper jaw, or the sinuses are too close to the jaw.

The dentist will first cut the gum tissue of the toothless gap and raise the tissue, exposing the bone. A small section of the bone is then cut out, and the sinus membrane filling the hole is slowly and gently pushed upwards, away from the jaw. A protective membrane – Geistlich Bio-Gide – is placed against the sinus, and then a substitute bone material – Geistlich Bio-Oss –  is filled up to several millimetres in height within the empty space.

Why is a bone graft done?

A bone graft may be done if there is not enough bone at the front end of the implant, underneath the gums. At ADHPL, we usually use the bone materials and one of the latest and best technologies – a PRF (Platelet Rich Fibrin) membrane, which is completely natural and made from the blood of the patient, resulting in faster healing of the gums and bone growth. Otherwise, we also have the resources to place a traditional man made membrane on the bone graft for bone growth.

Once the bone is in place, the membranes are sutured/stitched. Time is required for the grafted material to mesh with your bone, and then the implant can be placed.
