To assess the long-term outcomes (>4 years) following combined surgical resective/ regenerative therapy of advanced peri-implantitis lesions using two surface decontamination methods.
Material & Methods
Fifteen patients (n=15 combined supra- and intrabony defects) completed a follow-up observation period of 7 years. The treatment procedure included access flap surgery, granulation tissue removal and implantoplasty at bucally and supracrestally exposed implant parts, and a randomly assigned decontamination of the unmodified intrabony implant surface areas using either i) an Er:YAG laser (ERL), or ii) plastic curettes + cotton pellets + sterile saline (CPS). Intrabony defects were filled using a natural bone mineral and covered by a native collagen membrane.
At 7 years, both ERL and CPS were associated with similar mean BOP reductions (CPS: 89.99 ± 11.65% vs. ERL: 86.66 ± 18.26%) and CAL gains (CPS: 2.76 ± 1.92 mm vs. ERL: 2.06 ± 2.52 mm).
Combined surgical resective/ regenerative therapy of advanced peri-implantitis was effective on the long-term but not influenced by the initial method of surface decontamination.
