Simple and less invasive technique for fixation of iliac inlay bone block using dental implants in the atrophied posterior maxilla

The surgical technique and grafting materials used for sinus lift augmentation and simultaneous implant insertion were developed in the mid 1970s. New procedures were developed in the 1980s, in which iliac bone grafts were fixed to the residual ridge with implants. Today, less invasive techniques with lower morbidity have been developed for small bone defects, such as crestal elevation through the implant site. To treat severe atrophy and a bone height of less than 3–5 mm, other approaches are advantageous, such as the Caldwell-Luc entry. Depending on the severity of the situation, iliac crest bone block grafting guarantees high quantities of good bone for sinus augmentation. This report evaluates the usefulness of fixing the iliac crest bone block with implants. This technique significantly reduces the healing and waiting times and the number of operations.
