Mate r i als and me tho ds Duringthefirstsurgicalstage,asplit-thicknessflapwasdissectedandan osteotomyperformedtoprepareacrestalbonewindowusingasonicsur- gical device.The bonewindowwas subsequentlypushed apicallytoward the sinus and only collagen sponges were compressed into the subantral created space. After four months of healing, a second surgical stage fol- lowed using similar procedures to those used in the first stage, and im- plantsweresubsequentlyplaced. Re su lts Afterthreeyears,fromtheanalysesoftheconebeamcomputedtomog- raphy scans, no marginal loss was found and bone was observed all around the implant surface. No complaints were reported by the pa- tient. At the clinical follow-ups, no clinical signs of periimplant soft- tissue inflammation and no technical complications were noted during thethree-yearperiodofobservation.
