Peri-Implantitis Speaker: Dr. Georgios A. Kotsakis, DDS, MS, PhD

Georgios A. Kotsakis is a board-certified periodontist, Professor and Assistant Dean for Clinical Research at Rutgers School of Dental Medicine, and director of the NIH-funded Translational Periodontal Research Lab. His research on titanium particles, implant surface corrosion and the host response has changed how peri-implantitis is understood and treated. He lectures to scientific congresses, specialty societies and study clubs on the biology and clinical management of peri-implant disease.

Lecture topics

  • Why peri-implantitis is not periodontitis. Titanium particles, macrophage dysfunction and why antibiotics fail around implants (PNAS Nexus, 2026).
  • Do no harm to the implant surface. Abrasive versus non-abrasive decontamination and titanium release: evidence from a randomized clinical trial (2026).
  • The Impla-Safe non-surgical protocol. Peri-implant tissue assessment and step-by-step non-abrasive management for the general and specialty practice.
  • Surgical and regenerative treatment of peri-implantitis. Case selection, flap design, decontamination and what to expect long term.
  • From consensus to chairside. What the latest consensus reports on peri-implant disease mean for daily practice.

Formats: keynote and plenary lectures, half-day and full-day courses, hands-on workshops, and debates.
