Sometimes in the upper jaw and particularly in the upper molar position there is not enough bone to place a dental implant due to where the sinus is situated. This is easily rectified by a procedure called a sinus lift or sinus graft. It is an extremely common and predictable procedure to have and it gives good stability and end results.
Why do I need a Sinus graft?
When teeth are lost the sinus expands making the bone height too small for dental implants to gain good stability.
What does it involve?
A small precise window incision is made in the gum and the bone where the defect is. The sinus is then very carefully pushed gently up a few millimetres. In this space now provided it is packed with artificial bone granules (see guided bone regeneration) which is made up for a mix of calcium and phosphate which over time will be replaced by you own natural bone. The area is then stitched up and left to heal for approximately 6 months.
If the defect is a small one then it may be possible to have the implant placed at the same time as raising the sinus, Guy will inform you whether this is possible or not.
