Types of Permanent Dental Cements and Their Properties

Permanent dental cements vary widely in composition, properties, and clinical applications. Selecting the optimal cement depends on factors such as the type of restoration, tooth condition, esthetic demands, and mechanical requirements. The most commonly used permanent dental cements include resin-modified glass ionomer cements (RMGIC), resin cements, glass ionomer cements (GIC), and zinc phosphate cements.

Resin cements are favored for their superior adhesive qualities and esthetic versatility. These cements chemically bond to both tooth structure and restorative materials, providing excellent retention and marginal seal. They exhibit high compressive and tensile strength, making them suitable for all-ceramic restorations, veneers, and metal-ceramic crowns.

Glass ionomer cements offer the advantage of fluoride release, which can help reduce secondary caries risk. Conventional GICs have moderate mechanical properties but lower bond strength compared to resin cements. Resin-modified glass ionomer cements combine the benefits of resin and glass ionomer, offering improved bond strength and fluoride release.

Zinc phosphate cement, one of the oldest types, provides a long history of reliable retention but lacks chemical bonding and fluoride release. It has good compressive strength but is more soluble in oral fluids compared to resin-based cements.

Key properties to consider when choosing a permanent dental cement include:

• Bond strength: Determines retention and longevity of the restoration.
• Solubility: Low solubility reduces marginal breakdown and microleakage.
• Fluoride release: Offers cariostatic benefits.
• Esthetics: Important for anterior restorations.
• Handling characteristics: Working time, viscosity, and ease of cleanup.
• Biocompatibility: Minimizing pulpal irritation and sensitivity.

Cement Type	Bond Strength	Fluoride Release	Esthetics	Solubility	Typical Uses
Resin Cement	High	None	Excellent (various shades)	Low	Crowns, veneers, inlays/onlays, implants
Resin-Modified Glass Ionomer Cement (RMGIC)	Moderate to High	Moderate	Good	Moderate	Metal restorations, crowns, bridges
Glass Ionomer Cement (GIC)	Low to Moderate	High	Fair	Moderate to High	Temporary restorations, luting cement for metal crowns
Zinc Phosphate Cement	Moderate	None	Poor	High	Metal crowns, bridges (less common today)

Clinical Considerations for Choosing Permanent Dental Cement

When selecting the best permanent dental cement, clinicians must evaluate several clinical factors that influence performance and patient outcomes.

The preparation design and substrate condition play a critical role. For example, resin cements require proper isolation and dry field to achieve optimal bonding, which might be challenging in subgingival margins or with bleeding. In such cases, resin-modified glass ionomer cements, which are more tolerant of moisture, may be preferable.

The type of restoration material also dictates cement choice. All-ceramic restorations generally benefit from resin cements due to their esthetic requirements and adhesive bonding capabilities. On the other hand, metal-based restorations can be reliably cemented with conventional glass ionomer or zinc phosphate cements.

Patient factors such as caries risk, occlusal load, and esthetic expectations influence cement selection. In patients with high caries risk, fluoride-releasing cements like GIC or RMGIC may provide an additional preventive advantage. For high occlusal stress areas, cements with higher mechanical strength, such as resin cements, are recommended.

Other important clinical considerations include:

• Moisture control: Ability to maintain isolation during cementation.
• Ease of removal of excess cement: Especially critical for implant restorations to prevent peri-implantitis.
• Sensitivity: Some cements may cause post-operative sensitivity due to acidity or exothermic reactions.
• Setting time: Adequate working and setting time to allow proper manipulation.
• Compatibility with restorative material: Some resin cements require specific primers or surface treatments.

Advancements in Permanent Dental Cements

Recent developments in dental materials have enhanced the performance and versatility of permanent dental cements. Innovations include universal adhesives and dual-cure resin cements that improve bonding to a wide variety of substrates, including zirconia and lithium disilicate.

Self-adhesive resin cements have simplified clinical procedures by eliminating the need for separate etching and bonding steps. These cements contain functional monomers that chemically bond to tooth structure and restorative materials, reducing technique sensitivity.

Nanotechnology incorporation has improved mechanical properties and esthetics of resin and glass ionomer cements. Nanofilled resin cements offer enhanced polishability and wear resistance, important for long-term restoration survival.

Additionally, bioactive cements that release calcium and phosphate ions are under investigation to promote remineralization and enhance dentin-pulp complex health.
