Introduction
Choosing the right luting cement is one of the most critical decisions in restorative and prosthetic dentistry. Glass ionomer cement (GIC) and resin cement are the two most commonly used options — each with distinct advantages and limitations. This guide will help you make the right choice for your clinical situation.
Glass Ionomer Cement (GIC)
Glass ionomer cements are water-based materials that bond chemically to tooth structure and release fluoride, offering long-term caries protection.
Key Advantages
- Fluoride release — helps prevent secondary caries
- Chemical adhesion to enamel and dentine — no bonding agent required
- Biocompatible and gentle on pulp
- Easy to mix and use
- Cost-effective
Popular Products
- GC Fuji 1 — reliable luting cement for crowns and bridges
- GC Fuji CEM — paste-paste system for easy dispensing
- GC Fuji PLUS — resin-reinforced GIC for enhanced strength
- 3M ESPE Ketac Cem — radiopaque, fluoride-releasing luting cement
Best Used For
Metal crowns, stainless steel crowns, Maryland bridges, and cases where fluoride release is a priority.
Resin Cement
Resin cements are composite-based luting agents that offer superior bond strength and aesthetics, making them ideal for tooth-coloured restorations.
Key Advantages
- Excellent bond strength — mechanical and chemical adhesion
- Superior aesthetics — available in multiple shades
- Low film thickness for precise seating
- Ideal for all-ceramic and zirconia restorations
Popular Products
- 3M ESPE RelyX U200 — self-adhesive, no bonding agent needed
- 3M ESPE RelyX Luting Cement — resin-modified for permanent cementation
- 3M ESPE RelyX Veneer Cement — light-cured, translucent for veneers
Best Used For
All-ceramic crowns, veneers, inlays, onlays, fibre posts, and implant-supported restorations.
Quick Comparison Table
Glass Ionomer: Fluoride release ✅ | Bond strength moderate | Aesthetics limited | Technique sensitivity low
Resin Cement: Fluoride release ❌ | Bond strength high | Aesthetics excellent | Technique sensitivity high
Conclusion
Both cements have their place in modern dentistry. GIC is your go-to for metal restorations and high-caries-risk patients, while resin cement is essential for aesthetic, high-strength ceramic restorations. At KedarCart, we stock both options from leading brands to suit every clinical need.
