• Title : Why Implant Removal Should Be Followed by Immediate Alveolar Ridge Preservation

• Abstract : Bone remodeling after tooth extraction is well documented, with bundle bone resorption leading to significant reductions in both vertical and horizontal dimensions of the alveolar ridge, particularly within the first year. However, changes in alveolar bone following implant removal are less clearly understood, and the impact of the absence of bundle bone on ridge dimensions remains largely unexplored. Furthermore, the effects of implant removal on surrounding hard and soft tissues have not been systematically reported, leaving a gap in clinical knowledge regarding optimal strategies for site management and future implant placement. This case-based presentation aims to address this gap by comparing two clinical approaches: implant removal alone versus implant removal combined with immediate alveolar ridge preservation (ARP). In the cases presented, implant removal alone resulted in minimal hard tissue changes, consistent with the expectation that remodeling after implant removal is less pronounced than following natural tooth extraction. In contrast, sites treated with immediate ARP demonstrated preservation of ridge dimensions, providing a more favorable environment for subsequent implant placement. The findings suggest that simultaneous ridge preservation at the time of implant removal is both safe and effective, potentially minimizing alveolar bone loss and optimizing conditions for future implant rehabilitation. By presenting multiple cases, this study illustrates practical approaches and clinical outcomes associated with each strategy, highlighting the advantages of ARP in maintaining ridge architecture and facilitating predictable implant site development. Overall, this presentation emphasizes the importance of proactive management of explantation sites, even in the context of implant removal, and underscores the potential benefits of immediate ridge preservation for improving long-term treatment outcomes. These insights may guide clinicians in decision-making for implant site development and provide a framework for further research on post-implant removal bone remodeling.
