Bone harvested from the site of #18 will be used for #15 sinus lift (Fig.2 * as well as allograft). By the similar fashion, osteotomy at #15 is finished according to IS drill sequence except underdrilling (4.0x7.3 mm drill with 2 O-rings). Following use of DIO Sinus Approach Kit and placement of 2 pieces of PRF membrane and mixture of autogenous and allograft for sinus lift, a 4.5x11 mm IBS dummy implant is placed (Fig.2).
