Explain about Pergingival Regenerative Therapy

In case of one stage implants being treated or when the prosthesis has to be maintained a  Pergingival Regenerative Therapy is done. The membrane is perforated with a 3 mm hole and slid over the implant. The membrane should ensure complete coverage and isolation of the vertical bone defect. The flap is then sutured closely to the implant neck. It is very vital to remove the membrane after 6-8 weeks after surgery. This is necessary as there is no primary closure there is accumulation of plaque on the membrane and there is potential risk of infection of the membrane and the peri-implant site.
