Loss of upper posterior teeth may result in loss of bone volume neccessary for certain restorative procedures. Fortunately, the use of dental implants allow you to replace these missing teeth. However, the position of the maxillary sinus in the upper posterior areas may be too low for proper placement of dental implants.
This procedure allows the maxillary sinus membrane to be repositioned to allow for bone graft placement and eventual implant placement. Various grafting materials are used to encourage your own bone to replace the grafted bone, helping to stabilize the dental implant.
Under certain conditions, another procedure can be utilized. When possible, the bone remaining under the sinus floor is gently “pushed up”, thus lifting the floor of the “dropped” sinus. Bone replacement materials are then placed beneath this lifted bone. The bone materials are replaced with your own natural bone into this area.
Sinus Lift with bone graft augmentation procedures are highly predictable, with studies reporting over 95% success. Following sufficient healing of a sinus lift/augmentation (6-10 months), implants are placed in a predictable and successful manner. It is important to realize that if the sinus lift/augmentation procedure does not result in enough bone for implant placement, additional bone may be regenerated through a second sinus augmentation procedure at the time of implant placement.
