Summary

In dentistry, particularly in posterior teeth with extensive caries or old restorations, the extension of restoration margins below the gingival level presents a significant clinical challenge. In such cases, restorative procedures become more complicated, periodontal health may be adversely affected, and long-term tissue loss can occur. To overcome this problem, the "Deep Margin Elevation" technique has been developed. This approach aims to raise subgingival margins caused by caries or fractures above the gingival level, thereby providing a healthier and more favorable foundation for successful treatment.

In this study, two different materials will be used for deep margin elevation, followed by restoration of the teeth with indirect restorations fabricated using additive manufacturing technology, which has become increasingly popular in recent years. Two different additive manufacturing resins will also be applied in the restorative phase. The teeth treated with deep margin elevation and indirect restorations will be evaluated at baseline, 6 months, and 12 months according to the FDI criteria, as well as periodontal parameters due to the involvement of the gingival region.

This study aims to highlight the importance of material selection in restorative treatment planning and to scientifically demonstrate the impact of the applied technique on surrounding tissues. Furthermore, it will provide an evidence-based perspective on how adopting a tissue-friendly approach during restorative procedures may contribute to favorable long-term outcomes.
