The top tube returns to the centrifuge for another 30 minutes to make the second PRF membrane.  The first PRF membrane is inserted into the osteotomy and pushed into the sinus with empty feeling, followed by the sticky bone and last by the 2nd PRF membrane.  A 5x7.3 mm implant is placed with ~ 10 Ncm, followed by a 6.8x4 mm healing abutment (Fig.5,6).  There is no mushroom in the sinus, but hopefully the sticky bone will stick to the bottom of the sinus for maturation.  The site is infected 8 months postop (2 weeks post healing abutment removal); the sinus looks clouded (Fig.7).
