Sinus Lift Procedure
The maxillary sinuses are behind your cheeks and on top of the upper teeth. Sinuses are like empty rooms that have nothing in them. Some of the roots of the natural upper teeth extend up into the maxillary sinuses. When these upper teeth are removed, there is often just a thin wall of bone separating the maxillary sinus and the mouth. Dental implants need bone to hold them in place. When the sinus wall is very thin, it is impossible to place dental implants in this bone.
There is a solution called a sinus graft or sinus lift graft. The dental implant surgeon enters the sinus from where the upper teeth used to be. The sinus membrane is then lifted upward and donor bone is inserted into the floor of the sinus. Keep in mind that the floor of the sinus is the roof of the upper jaw. After several months of healing, the bone becomes part of the patient’s jaw and dental implants can be inserted and stabilized in this new sinus bone.
The sinus graft makes it possible for many patients to have dental implants when years ago there was no other option other than wearing loose dentures.
If enough bone between the upper jaw ridge and the bottom of the sinus is available to stabilize the implant well, sinus augmentations and implant placement can sometimes be performed as a single procedure. If not enough bone is available, the sinus augmentation will have to be performed first, then the graft will have to mature for several months, depending upon the type of graft material used. Once the graft has matured, the implants can be placed.
Sinus Grafting is a procedure in which the sinus floor is raised developing a bone housing for the placement of dental implants.
Several techniques can be used to raise the sinus and allow for new bone to form. Dr. Cullen will explain your options for graft materials, which can regenerate lost bone and tissue.
Depending on your procedure, the bone usually will develop in about 4 to 12 months before implants can be placed. In some cases, the implant can be placed at the same time the sinus is grafted.
Most patients experience minimal discomfort during this procedure.
Before Grafting there is a large sinus cavity.
The sinus cavity is filled with bone in preparation for an implant. The success of implants placed in the bone is 95%.
