A sinus lift is surgery that adds bone to your upper jaw in the area of your molars and premolars. It’s sometimes called a sinus augmentation. The bone is added between your jaw and the maxillary sinus, which are on either side of your nose.
For a successful implantation procedure adequate bone is the key factor. The upper back region of jaw is one of the difficult areas for implant placement due to the proximity of sinus. Due to the longer periods of missing teeth bone erodes & adequate bone support required for implant procedure is lost. In such case we opt for sinus lift procedure.
In this procedure an incision is made in the region premolar & molars over the gum, a small window is made in the bone. Then sinus membrane is separated from bone & the membrane is slightly pushed upward to create space for bone graft.The amount of bone graft depends upon the bone required for implant placement. The patient is made to wait for 4-6 months & later follows implantation procedure.
