Objectives: The present randomized clinical trial assesses the six-month outcomes following\nsurgical regenerative therapy of periimplantitis lesions using either an electrolytic method (EC) to\nremove biofilms or a combination of powder spray and electrolytic method (PEC). Materials and\nMethods: 24 patients with 24 implants suffering from peri-implantitis with any type of bone defect\nwere randomly treated by EC or PEC. Bone defects were augmented with a mixture of natural bone\nmineral and autogenous bone and left for submerged healing. The distance from implant shoulder to\nbone was assessed at six defined points at baseline (T0) and after six months at uncovering surgery\n(T1) by periodontal probe and standardized x-rays. ........................
