Is There Space for Resin Composite Restorations in a World of CAD-CAM and Digital Dentistry? Two-Year Follow-Up of Clinical Outcomes Using the Direct–Indirect Technique

Abstract

Objective

This clinical report seeks to elucidate the versatility and mid-term outcomes of the direct–indirect technique. It presents a comprehensive step-by-step protocol for restoring anterior dentition across various clinical scenarios in accordance with the principles of the polychromatic layering technique.

Clinical Considerations

This clinical report was divided into two phases. First, an urgent procedure due to the debonding of an interim restoration in tooth #10 was followed by crafting a direct–indirect veneer. Then, in the six-month follow-up appointment, a complete esthetic improvement in the anterior dentition (teeth #8, #9) with two techniques and different materials for each tooth was observed: In tooth #8, a direct incisal edge augmentation was performed, while in tooth #9, a thin contact lens-type direct–indirect fragment was created to improve the form of the tooth. The restorations were followed up for a 24-month mean, with the following criteria: Color, wear, adaptation, marginal discoloration, and integrity.

Conclusions

The direct–indirect technique showed optimal clinical outcomes after a mid-term follow-up, making it an option to traditional direct veneering, ceramics, and CAD-CAM materials.

Clinical Significance

The direct–indirect technique amplifies the scope of resin composite restorations, providing optimal esthetic performance, broad indications, and mid-term longevity regardless of the selected restorative composite material or veneer type.
