Sinus floor augmentation technique and simultaneous implant placement, part II: the 2-stage approach

The 1-stage osteotome sinus floor augmentation and simultaneous implant placement technique has been previously reported as a simple solution to heighten the maxillary posterior region to nearly 5- to 6-mm bone height. In this report, a patient with initial bone height of 2 to 3 mm in the extracted site of #3 was treated with the 2-stage osteotome technique. In the first stage, the sinus floor was grafted and augmented up to 5 to 6 mm. In the second stage, 9 months later, the same area was regrafted and the implant was placed. Eight months after the second stage, radiographs showed the entire 10-mm length of the implant was covered with new bone and the implant was solid and functional.
