Dislodged d-PTFE membrane with exposed implant thread?

Authors

Did an immediate implant placement on tooth 26 with bone graft and cover with d-PTFE membrane (Permamem). 5 days later noted the sutures were loose but the membrane still in position. I re-fix the membrane. One week later, the membrane was partially dislodged. No sign of infection and there were epithelial growth under the membrane. I removed the membrane, irrigate with CHX copiously and instruct the patient to irrigate daily. But I noticed implant thread exposure at the crestal level. Will it help if I leave it be as long as there are no infection, and do a connective tissue graft when I place the healing abutment?
