Fabio Caliendo describes a crestal sinus lift with a 2 mm drill, Elevate tips with stops at 6 mm anteriorly and 3 mm posteriorly, collagen sponge and Biosorb bone. He reports using a panoramic radiograph and intraoperative intraoral radiographs.
Sinus lift via the crestal approach, initially performed only with the 2 mm drill to position the markers, and then only with the Elevate tips: stop at 6 mm for the anterior one and at 3 mm for the posterior one; collagen sponge inserted first, then Biosorb bone.
