A procedure that adds bone beneath the sinus in the upper jaw so that implants can be placed.
What it involves
In the upper back jaw the sinus can sit close to the ridge, leaving too little bone for an implant. A sinus lift gently raises the membrane lining the sinus and fills the space with bone graft material. It is done through the side of the jaw or from the ridge.
Who it suits
Considered when the upper back teeth are missing and a scan shows too little bone height. Active sinus infections, heavy smoking and some medical conditions make it unsuitable until addressed.
How it usually works
Assessment with a 3D scan, then surgery under local anaesthetic, sometimes with sedation. The membrane is lifted and graft material placed. Implants may be inserted at the same time or after several months of healing.
Risks and things to consider
The sinus membrane can tear, which may require the procedure to stop or be repeated. Infection, nose bleeding and sinus problems can occur. Swelling and bruising are expected. Healing times are long and the graft can fail.
Questions to ask before you decide
Is a sinus lift definitely needed, or could shorter implants work? Will implants go in at the same time or later? What are the warning signs I should report after returning home?
