Gelatin Sponge VS PTFE Membrane for Socket Sealing After Immediate Implant Placement

Digital panoramas will be made to assess the implant sites. The included patients are assigned to their respective groups randomly. After implant submerging in the study group 2 layers of hemostatic resorbable gelatin sponge is fixed in the implant site; while with the control group PTFE is fixed. After 3 weeks the PTFE was removed while the gelatin sponge should be resorbed. 3 months later the implants are to be assessed for stability and a reverse torque test was used to confirm osseointegration during uncovering. Follow-up appointments at 1,3 weeks and 1,2 \& 3 months were planned.
