Maxillary sinus bone augmentation is a surgical procedure for altering the morphology of the posterior maxilla and creating sufficient bone to accommodate implants. The implant placement may be staged or completed at the time of sinus augmentation.
There are two types of sinus augmentation procedures – internal or osteotome technique and external or lateral-wall technique. Thorough analysis of the bone and the sinus is completed prior to the procedure. The type of sinus augmentation that is needed and the details of the procedure will be discussed prior to the appointment.
