To reduce the exposure, the implant will be placed deeper, as shown by arrow in Fig.3.  PRF membrane and collagen membrane (Fig.4 red line) will be placed against the buccal gingiva, while PRF associated sticky bone (allograft, pink circle) will be packed around the exposed implant threads and a long-cuff abutment (yellow).  Finally an immediate provisional (Fig.5 white) will be fabricated to cover the bone graft.  PRF/Implant-Assisted Bone Graft Last Next Xin Wei, DDS, PhD, MS 1st edition 01/20/2019, last revision 01/20/2019
