What Are the Causes of Sinus Lift?

A sinus lift is a type of surgical procedure in dentistry that is targeted to grow the bone volume in the region that surrounds the upper jaw bone (posterior maxilla), molar, and premolar teeth. All these modifications come at the expense of maxillary sinus’s volume. As a result, this procedure is also referred to as sinus graft, sinus floor augmentation, and sinus procedure.

Both of the maxillary sinuses are small air-filled holes, positioned above the back teeth, below the cheeks, and around each of the nose sides. So, why does the dental surgeon deem it necessary to increase the bone volume of the posterior maxilla? There are multiple reasons for this decision; however, mostly, they do this in order to place a new set of teeth via dental implants.


Dental surgeons can lower sinus due to the following reasons.

1. Inflamed Maxillary Sinuses

Patients who deal with sinus-related issues like sinusitis often struggle with bone resorption. As a result, their sinus floor gets lowered slowly and gradually.

2. Loss of Teeth

Patients lose their natural tooth/teeth because of dental decay, gum diseases like periodontitis or dental trauma.

The area without the tooth is called the edentulous ridge. After some time, it begins to lose its height and weight while at the same time, the maxillary sinus floor also lowers down.

In some cases of gum diseases, the loss of bone can be quite significant. Eventually, when a doctor recommends a dental implant, they cannot proceed with the osseointegration as it requires a specific bone volume level.

3. Genetic Defects

Some babies have birth defects due to which their maxillary sinuses are unusually large. Sometimes, these defects can also cause people to grow up with missing teeth.


Usually, dental surgeons use general anesthesia before starting the treatment.

  • The loss of teeth speeds up bone loss.
  • After some time, the area that was once home to the previously-lost teeth, the sinus begins to enlarge in that area.
  • When a dental implant is attached with the reduced bone, it is unable to adjust and the implant ends as a failure.
  • To begin the sinus procedure, the dental surgeon creates a short-term opening in any of the two areas.
  • The surgeon uses a dental tool to lift the sinus membrane and restructures it back to its prior position. As a result, there is enough room to place the bone graft—a bone that is used as a substitution for the lost bone volume.
  • When the right amount of bone is added, the surgeon places a dental implant.
  • As time passes, the new bone and implant heal and progress into a powerful bond.
