Alveolar ridge preservation following tooth extraction is critical for achieving optimal implant positioning and esthetic outcomes. It aims to limit post-extraction resorption while maintaining ridge volume and contour. Successful treatment relies on careful case selection, precise surgical execution, and the indication-based combination of biomaterials, now complemented by bone substitutes enhanced with hyaluronic acid and magnesium-based shield techniques. A clear understanding of the biological processes governing bone and soft tissue healing remains essential for predictable results.

Challenges are particularly evident in the esthetic zone, where both functional and esthetic outcomes must be considered. Preservation of ridge contour supports a natural emergence profile, contributes to soft tissue stability, and facilitates integration between the implant and surrounding tissues. The combined use of hyaluronic acid–enhanced materials and magnesium-based shield techniques may further support favorable healing dynamics and clinical outcomes.

 Learning objectives:

• Understand biological principles of post-extraction sockets and dimensional changes that require alveolar ridge preservation
• Acquire technical and surgical protocols to manage compromised sockets, including the application of bone substitutes enhanced with hyaluronic acid and magnesium-based shield techniques
• Learn how to select biomaterials to achieve long-term functional and aesthetic outcomes
