In a recent "Just Ask" session from the European Association of Osseointegration (EAO), renowned expert Ignacio Sanz Sánchez shared his insights into horizontal ridge augmentation, focusing on modern techniques for bone grafting around dental implants. The session, part of the EAO’s fall season, highlighted the importance of understanding the right approach to bone augmentation, particularly when treating challenging defects in the oral cavity.
Dr. Sanz Sánchez began by discussing the key factors that influence the choice of grafting technique, such as the type of defect, the implant's position, and the need for soft tissue management. Horizontal ridge defects, often occurring after tooth extraction, require careful evaluation. If an implant site lacks sufficient bone to fully encase the implant, augmentation becomes essential. The primary goal is to restore the bone in such a way that the implant can be placed with proper stability and aesthetics.
He explained that the treatment options for horizontal ridge defects are generally divided into three categories: using resorbable membranes with particulate grafts, block grafts, or non-resorbable membranes. Each of these strategies has specific advantages depending on the defect’s characteristics. For example, resorbable membranes and particulate grafts remain the gold standard for fenestration-type defects.
Sanz Sánchez emphasized that the complexity of each case dictates the choice of technique. He discussed the benefits of using slow-resorption grafts like DBBM (demineralized bone matrix) when dealing with more extensive bone loss, particularly for cases requiring long-term stability. In his clinical practice, he often combines autologous bone with synthetic grafts to ensure optimal results.
One key takeaway from his presentation is the importance of precise flap management and achieving passive closure, which significantly impacts healing and the success of the grafting procedure. He also noted that less invasive techniques, such as using micro screws instead of pins, are becoming increasingly popular due to their efficiency and ease of use.
Overall, Dr. Sanz Sánchez's presentation provided a comprehensive, evidence-based approach to horizontal ridge augmentation, offering valuable insights for dental professionals looking to refine their skills in bone regeneration. His expertise in using a variety of membranes, grafting materials, and surgical techniques has helped shape contemporary practices in implantology, making this a must-watch session for those in the field.
