Save or Replace? Rethinking Periodontal Regeneration in the Implant Era (Englefield Green, 19 October 2026)

In the implant era, the decision to retain a periodontally compromised tooth or replace it with an implant remains an important clinical challenge. Advances in periodontal regeneration and minimally invasive surgical techniques have expanded the possibilities for preserving teeth with intrabony periodontal defects and improving their long-term prognosis.

Learning objectives

- Identify key factors guiding the decision to retain a periodontally compromised tooth or replace it with an implant.
- Recognise the indications and principles of contemporary periodontal regeneration, including minimally invasive approaches such as NIPSA.
- Integrate regenerative treatment options into evidence-based clinical decision-making in the implant era.

In the implant era, the decision to retain a periodontally compromised tooth or replace it with an implant remains an important clinical challenge. Advances in periodontal regeneration and minimally invasive surgical techniques have expanded the possibilities for preserving teeth with intrabony periodontal defects and improving their long-term prognosis.

This lecture will explore the key factors influencing the “save or replace” decision, with particular emphasis on case selection, defect characteristics and contemporary regenerative strategies. Minimally invasive approaches, including the Non-Incised Papillae Surgical Approach (NIPSA), will be discussed and illustrated through clinical cases and findings from ongoing research. The aim is to provide a practical and evidence-based perspective on the potential of periodontal regeneration and its role in treatment planning before considering tooth extraction and implant replacement.
