Reconsidering glass-ionomer cements for direct restorations

Area of Science:

• Dental Materials Science
• Restorative Dentistry

Background:

• Glass-ionomer cements (GICs) are established dental materials with diverse applications.
• Traditional uses include bases, liners, luting agents, and foundation restorations.
• GICs possess unique properties suitable for advanced restorative techniques.

Purpose of the Study:

• To discuss the potential advantages of GICs in direct dental applications.
• To highlight GIC synergy with composite resins in "sandwich" or hybrid restorations.
• To identify scenarios where GICs are superior to other restorative materials.

Main Methods:

• Review of GIC properties and clinical applications.
• Discussion of GIC synergy with composite resins.
• Inclusion of two brief case reports illustrating GIC use.

Main Results:

• GICs demonstrate unique attributes beneficial for full-contour and hybrid restorations.
• Synergistic interactions with composite resins enhance restorative outcomes.
• Case reports showcase successful direct applications of GICs.

Conclusions:

• GICs present viable alternatives for direct restorations in specific clinical situations.
• Their unique properties make them ideal for "sandwich"/hybrid techniques.
• GICs offer advantages where composite resins may not be the optimal choice.
