In a recent Just Ask live session, Professor Ronald Jung from the University of Zurich shared valuable insights on alveolar ridge preservation (ARP), focusing on the importance of decision-making before tooth extraction. ARP is crucial for maintaining bone volume and ensuring successful implant placement post-extraction. Jung emphasized that the extraction process should never be a reactive one but part of a well-thought-out treatment plan that considers future restorative options.
Professor Jung's presentation illustrated the significant bone loss that occurs naturally after tooth extraction, with an estimated 50% loss in the first six months. This bone loss can complicate later implant procedures, making early intervention essential. He shared two cases involving young patients, Laura and Caroline, to highlight the contrasting outcomes of different treatment approaches. Caroline, who underwent alveolar ridge preservation, maintained adequate bone volume, allowing for smoother implant placement years later. In contrast, Laura, who had no intervention, experienced significant bone loss and required complex procedures to reconstruct the area.
Jung stressed that alveolar ridge preservation should be considered for all patients where implant placement is not immediately possible. It not only maintains bone volume but also reduces the need for invasive grafting later. He also discussed the role of materials used in ARP, explaining that while no material guarantees 100% preservation, bovine bone and allogeneic materials are most commonly used with good results.
The key takeaway was the importance of making the right decision before extraction—whether to proceed with immediate implant placement, perform ARP, or allow spontaneous healing. For cases where an implant isn’t feasible within the next two months, ARP is the recommended approach, ensuring the best outcome for future restorative treatments.
Jung concluded that, just as preventive care revolutionized dentistry for caries, alveolar ridge preservation could transform post-extraction treatment, providing long-term benefits with less invasive methods.
