Amalgam-Free Solutions: A Review of GC EQUIA Forte HT and everX Flow Materials

Shanghai, China — At the 2025 FDI World Dental Congress (FDIWDC25), GC introduced its latest solutions for restorative dentistry. EQUIA Forte HT and everX Flow were positioned as modern amalgam alternatives, focusing on a combination of strength, handling properties, and restoration aesthetics when used with current clinical protocols.

At the congress, the company demonstrated to clinical specialists the indications, working protocols, and applications for both materials, while also providing case demonstrations and educational resources to facilitate the transition from amalgam restorations to modern composite and cement technologies.

Materials and Protocols

• EQUIA Forte HT — a glass hybrid restorative material with enhanced mechanical strength and aesthetics; used according to protocols typical for modern glass ionomer/hybrid systems, with a protective coating to improve polish and wear resistance.
• everX Flow — a short-fiber-reinforced flowable composite, positioned as a base/liner to enhance fracture resistance and distribute stress in large cavities.

Summary

According to the manufacturer, combining these materials enables restorations that can compete with amalgam in strength, procedural efficiency, and aesthetics in a range of clinical situations. The demonstrations emphasized:

• The applicability of EQUIA Forte HT as an aesthetic alternative for Class I–II cavities under moderate occlusal loads;
• The use of everX Flow as a reinforcing layer in the reconstruction of large cavities and in preparations for inlays/extensive composite restorations;
• The necessity of adhering to modern protocols for adhesion, isolation, and layered restoration to achieve optimal longevity.

Clinical Evaluation and Limitations

It should be noted that the claims are primarily based on manufacturer data and demonstrative clinical cases; a full comparison with amalgam requires independent long-term randomized studies that account for restoration survival under intensive occlusal load and variability in preparation techniques.

Clinical significance

For practicing dentists, the announced solutions represent an expansion of the material arsenal for the gradual transition of a practice to amalgam-free approaches. Clinicians should consider the following practical aspects:

• Precise indication determination: For small to medium-sized restorations under load, EQUIA Forte HT may be justified, whereas for large defects, it is preferable to use everX Flow as a reinforcing base followed by coverage with a high-strength composite.
• Adhesive protocol and isolation (rubber dam) remain critical for the success of amalgam-free restorations; incorrect application technique reduces expected longevity.
• Evaluation of occlusal contacts and management of masticatory load: In high-load areas, the combined use of reinforcing matrices and adequate external coverage is indicated to prevent fractures.
• The need to inform patients about the balance of advantages and limitations of new solutions, as well as the potential need for restorative revision in the long term.

Expert commentary

From a practical standpoint, the combination of glass hybrid and short-fiber-reinforced materials represents a logical evolutionary step toward aesthetic and more biocompatible restorations. To reliably replace amalgam across various clinical scenarios, it is essential to combine appropriate material selection, strict adhesive protocols, and a well-founded restorative strategy: base reinforcement (everX Flow) — restorative core or veneer (top composite or EQUIA coating), adequate occlusal adjustment, and dynamic monitoring.

Clinicians are advised to monitor the emergence of independent clinical studies on the longevity and mechanical properties of these systems and to apply them considering the patient’s individual situation and their own clinical experience.
