Many times when a patient desires to have an implant, the length of the implant may be limited due to a limited amount of available bone and the maxillary sinus being in the way. These circumstances occur when a molar is withdrawn without the socket being grafted, causing the maxillary sinus to broaden, overrunning space that was occupied by the tooth and surrounding bone. Sinus lifting is known as the surgical elevation of the thin membrane that surrounds the maxillary sinus. A compartment filled with bone graft material will be created once this membrane is positioned upright in conjunction with the walls of the sinus. Approximately five months later, this bone graft material should turn into bone allowing for implants to then be placed. Although the sinus lifting procedure is a long process, it will positively benefit you in the future by being able to receive an implant.
