What is a sinus lift?

A sinus lift raises and thickens the bone in the upper jaw by lifting the sinus membrane and inserting bone graft material beneath it. This procedure is necessary when the space between the upper teeth and the maxillary sinus is too thin to support a dental implant securely. The sinus is an air-filled cavity above the back teeth, and in many patients, bone loss from missing teeth or age reduces the available bone height in this region.

The procedure works by carefully elevating the sinus lining through a small opening in the jaw bone, then packing bone graft material (often sourced from the patient's own bone, a donor bank, or synthetic material) into the space created. Over several months, this graft integrates with the existing bone, building up the height and density needed for implant placement.

Sinus lifts are common in restorative dentistry because upper back teeth are prone to bone loss after extraction, and replacing them with implants often requires this augmentation. The healing period typically takes 4-6 months before implants can be placed. For patients in Kuala Lumpur seeking upper jaw implant restoration, dentists may recommend a sinus lift as part of a multi-stage treatment plan.
