After 5 months of uneventful healing of implants in area #8 and #9 with simultaneous Bio-Oss collagen bone graft and titanium reinforced non-resorbable high-density PTFE membrane and covered with a non-cross linked porcine membrane, I now see a small lesion resembling a sinus tract that is present in the immediate vicinity (2mm) of one tenting screw in area of #8. The lesion bleeds very easily and would not heal after I tried to cauterize it with a soft tissue laser. The size of the lesion is about 1.5-2mm. What would you do to resolve this situation since the non-resorbable membrane had to be removed after only 8 months of healing? Please note that area #9 has also received a supporting tenting screw and continues to heal without any problems. Thank you and your help in this matter is greatly appreciated.
