What is a sinus lift?

Has your dentist told you that you need a sinus lift? If so, then you are not alone. 1 in every 5 people will need a sinus lift before their dental implants can be inserted.

A sinus lift, referred to also as a “sinus floor augmentation procedure”, is a method of adding bone to your upper jaw. This is needed to support the placement of dental implants in cases where there is insufficient bone to hold the implants in place.

During a sinus-lift procedure, new bone is added between your jaw and the maxillary sinuses, which are cavities, or pockets, on either sides of your nose. To make room for the bone, the sinus membrane is moved upward, and bone replacement material is placed beneath it. A successful sinus-lift procedure will create a bone mass that will enable dental implants to be inserted, and remain in place for many years.

Why do I need a sinus lift?

A sinus lift is performed when there is not enough bone in the upper jaw to allow room for dental implants.

Sinus in original state: Implants can be placed Expanded sinus: Bone is too thin

This happens when the maxillary sinus, which naturally grows larger with age, is too close to the upper jaw for implants to be used.

You will most likely need a sinus-lift procedure if you lost your teeth a long time ago. Once teeth are lost, bone atrophy begins. If teeth have been missing for a long time, there is often not enough bone left to place implants, in which case a sinus lift procedure is needed.

There are several ways to perform a sinus lift. The traditional sinus lift surgery, the “open method”, also referred to as the “lateral window” method, has not changed in several decades.
