Fig. 1-42. A, The pin is driven only a few millimeters into the bone. It is then radiographed to check its direction in relationship to the lowest septal floor of the maxillary sinus and to the root apex of the nearest abutment tooth. B, If the angle is correct, the pin is driven in deeper and again radiographed to check its direction. C, Finally, the pin is driven as deep as the anatomic obstructions permit. D, The first implant pin is in position. It assumes a mesiopalatal inclination.
