The nasal cavity and nasal sinus form the top of our upper jaw. The nasal sinus may sometimes grow beyond its normal size with time. Occasionally, the shape of the sinus needs to be modified for certain dental procedures.
A sinus lift refers to the procedure that modifies the shape of the upper jaw sinus. A sinus lift is a bone grafting procedure involving the upper jaw or maxilla.
The upper jaw sinus tends to increase in size with time after the upper molars are removed. This results in insufficient bone height for placement of dental implants in the back of the upper jaw.
In order to increase the height/volume of bone, the sinus is gently opened and bone graft material is added. Either natural (autologous) bone or other bone substitutes are used for a sinus lift. The graft material will eventually transform into the patient''s own healthy bone. Once the bone has consolidated, implants of adequate length can be inserted and later on, new teeth will be placed.
A sinus lift procedure is a minor surgery that can be carried out under local anaesthesia and the procedure will be performed in an out-patient setting.
In the situation where a patient may be worried about the procedure, s/he may choose to have the procedure under sedation, which will relax the patient during the procedure and best of all, the person would not remember the procedure afterward.
