A lateral sinus lift is a procedure that allows us to increase the amount of available bone for implant placement in the upper jaw.
The tissue is elevated and then a window is created in the bone to expose the sinus membrane. Through this window, the sinus membrane is lifted and room is made for the bone graft. The graft is placed into the space where the sinus used to be.
Implants may be placed at the same time as grafting or at a later time. A resorbable collagen membrane is used to cover the access window and the flaps are then sutured to allow for healing.
Once healed, the implants can be restored to create an esthetic and functional tooth replacement solution.
Vertical sinus lifts are necessary when the maxillary sinus gets in the way of implant placement.
The advantage of a vertical sinus lift is that implants can be placed at the same time and it is minimally invasive.
In performing the procedure, the site is prepared to receive the implants and the sinus membrane is elevated at the same time. A piezotome surgical unit is used to reduce the risk of membrane perforation and complications. Bone graft is placed into the space created prior to implant placement.
The graft will consolidate with the surrounding bone and integrate with the implants over the course of several months. Once healed, the implants may be restored with abutments and crowns to provide esthetics and function.
