Large posterior defects, especially those extending below the cemento-enamel junction, are common. Deep margin elevation (DME) has become a less invasive technique for restoring these defects. However, critical factors, such as the type, height, and form of the base materials, could affect the marginal quality, fracture resistance of restorations, and the periodontal health. At present, a unified and standardized design principle and clinical operation procedure of DME for reference are lacking. This review summarizes the research progress on material selection, lifting height, and gingival wall edge shape design and stress distribution in DME.

Key words: cervical margin relocation, composite resin material, microleakage, marginal adaptation, stress distribution
