Sinus Lift

This is a surgical procedure that aims to increase bone mass in the jaw in the region of molars and premolars.

When should it be done?
When there is not enough bone in the upper jaw to allow the placement of an implant. The lack of bone in the upper jaw is caused by bone resorption after tooth extraction. Periodontal disease can contribute to greater bone loss. There are individual variations with regard to the size of the maxillary sinus and it's size  may increase with age.



Preparation
It's necessary a  radiographic exam and computed tomography (CT) to assess the dimensions and shape of the maxillary sinus to prepare the surgery.

 

 

How is it done?
First an incision is made in the gum in the region of the premolars, molars and the tissue is raised, exposing the bone. Then a small oval window is opened in the bone. On the other side of the window is visible the membrane covering the sinus. This membrane is then gently pulled up and the space that was formerly occupied by the sinus is filled with bone graft material. The gum is placed in position and sutured.

 

 

 

 

How is the post-op?
After surgery, patients typically present some swelling and some loss of blood through the mouth and nose. It is important not to force the nose and avoid sneezing because it may displace the material that was placed inside. It is prescribed medication to control pain, inflammation and prevent infection.

The implants can be placed immediately or after a few months (mean 8 months) after surgery, depending on each case.
