Sinus Lift Surgery
A key to implant success is the quantity and quality of the bone where the implant is to be placed. If you’ve lost bone in the upper back jaw area due to reasons such as periodontal disease or tooth loss, you may be left without enough bone to place implants. Sinus lift surgery can help correct this problem by raising the sinus floor and developing bone for the placement of dental implants. Several techniques can be used to raise the sinus and allow for new bone to form. In one common technique, an incision is made to expose the bone. Then a small circle is cut into the bone. This bony piece is lifted into the sinus cavity, much like a trap door, and the space underneath is filled with bone graft material. Your periodontist can explain your options for graft materials, which can regenerate lost bone and tissue.
Finally, the incision is closed and healing is allowed to take place. Depending on your individual needs, the bone usually will be allowed to develop for about four to 12 months before implants can be placed. After the implants are placed, an additional healing period is required. In some cases, the implant can be placed at the same time the sinus is augmented.
Undergoing sinus lift surgery has been shown to greatly increase your chances for successful implants that can last for years to come. Many patients experience little to minimal discomfort during this procedure.
In some instances of All-on-4™ patients where there is extremely atropic upper (maxilla) or lower (mandible) bone the surgeon may opt to do a simultaneous sinus lift procedure.
