Implant can be problematic or even impossible because of the proximity of their position with the maxillary sinus, which is located in the rear upper jaw, in the region around the molars and premolars. It goes without saying that when placing implants we should not go through the floor of the maxillary sinus and of course do not lace implants that enter in the sinus area. The risks are understandable; rejection of the implant and subsequent inflammation of the sinus, more commonly know as sinusitis.

Fortunately, we can provide solutions to these problems with sinus lift procedures.

During these procedures, we can move the floor sinus upwards creating space to accommodate a suitable graft and eventually one or more implants. There are two procedures, closed sinus floor elevation, which can be used when there is enough bone and simultaneous implant placement can be achieved, and the open sinus floor elevation, which is used when the available bone is really minimal. In the latter case augmentation is performed and the first stage while the implant is usually placed at a second stage.

Both procedures are completely safe and there are many studies that support them. But each has its indications and contraindications. Careful clinical examination of the area, a detailed medical history with necessary radiographs can determine in which patient can apply which technique in order to achieve the best result.
