Restoring teeth with subgingival margins poses significant clinical challenges, particularly in achieving proper isolation, maintaining periodontal health, and ensuring long-term restoration success. As contemporary dentistry shifts toward maximal tooth preservation, deep margin elevation (DME) has emerged as a game-changing technique for managing subgingival cavities while preserving tooth structure and avoiding invasive surgical interventions. However, its clinical application remains a topic of debate due to technical sensitivity and biological considerations. This lecture provides a comprehensive roadmap for predictable DME implementation by presenting an evidence-based, step-by-step approach . Emphasis will be placed on maintaining marginal integrity, achieving predictable bonding, and preserving periodontal harmony. By the end of the session, clinicians will be equipped with practical strategies and clinical confidence to integrate Deep Margin Elevation effectively into their daily practice.

Objectives:

1. Develop evidence-based selection criteria for DME cases

2. Identify the appropriate materials and adhesive protocols for successful DME

3. Master step-by-step clinical protocols for predictable execution

4. Evaluate long-term outcomes and manage complications

5. Integrate DME into a comprehensive treatment planning approach
