Description

Preva Cem – Glass Ionomer Luting Cement

Preva Cem is specifically designed for permanent cementation of indirect restorations and orthodontic bands. The translucent universal light yellow shade blends well with various restorations while delivering consistent clinical performance. Preva Cem, Prevalent’s professional glass ionomer luting cement is radiopaque, self-curing, fine-particle formula provides excellent adhesion to tooth structure with the added benefit of continuous fluoride release

Clinical Applications

• Metal Restorations- Cementation of metal inlays, onlays, crowns, and bridges
• All-Ceramic Restorations- Cementation of high-strength ceramics including zirconia crowns and bridges
• Stainless Steel Crowns- Reliable cementation for pediatric and adult SSC restorations
• Orthodontic Bands- Secure attachment of metal orthodontic bands
• Permanent Cementation- Long-term cementation of various indirect restorations
• Pediatric Dentistry- Excellent for primary teeth restorations and orthodontic appliances

Why Choose Preva Cem?

• True Chemical Bonding
  Unlike purely mechanical cements, Preva Cem chemically bonds to tooth structure through ionic exchange with calcium. This provides superior retention without complex bonding protocols.
• Fluoride Protection Where It Matters
  The continuous fluoride release happens right at the restoration margins – exactly where secondary caries most often develops. Long-term protection built into your cementation.
• Versatile for All Restorations
  From simple metal crowns to high-strength zirconia restorations, Preva Cem handles them all. One cement for your routine cementation needs.
• No Complex Protocols
  No etching, priming, or light curing required. Simple mix-and-cement procedure saves chair time and reduces technique sensitivity.
• Excellent Marginal Seal
  Fine-particle formulation creates thin, precise film thickness for accurate restoration seating and minimal margin gaps.
• Moisture-Tolerant Chemistry
  Less moisture-sensitive than resin cements. More forgiving in challenging clinical situations where complete isolation is difficult.
• Pediatric Friendly
  Ideal for children’s dentistry. Fluoride release benefits developing teeth. Easy to use with cooperation-limited patients.

Frequently Asked Questions

Q: What is glass ionomer luting cement?

A: It’s a dental cement that chemically bonds to tooth structure and releases fluoride, providing reliable cementation with caries protection.

Q: Does it really bond chemically to teeth?

A: Yes. Polyacrylic acid in the liquid reacts with calcium in tooth structure, creating true chemical adhesion.

Q: Can I cement zirconia crowns with this?

A: Yes. Preva Cem is suitable for cementation of high-strength all-ceramic restorations including zirconia crowns and bridges.

Q: Does it release fluoride?

A: Yes. The fluoroaluminosilicate glass provides continuous fluoride release for ongoing caries protection at margins.

Q: Do I need to light cure it?

A: No. Preva Cem is self-curing. It sets on its own without requiring a curing light.

Q: Should I desiccate the tooth surface?

A: No. Keep the prepared tooth visibly moist (glistening) for optimal chemical bonding. Over-drying reduces bond strength.

Q: Can I use this for orthodontic bands?

A: Absolutely. It’s specifically indicated for cementation of orthodontic metal bands.

Q: Is it radiopaque?

A: Yes. Preva Cem is radiopaque for easy radiographic visualization and diagnosis.

Q: Can I use it for pediatric stainless steel crowns?

A: Yes. Excellent choice for stainless steel crown cementation in pediatric dentistry.

Q: How long until I can finish?

A: Final finishing and polishing can begin approximately 5 minutes after seating the restoration.

Q: Why shouldn’t I shake the powder bottle?

A: Shaking creates inconsistent powder density. Just tap lightly before measuring for accurate dispensing.

Q: Can I use it for filling cavities?

A: No. Preva Cem is a luting cement only. It’s contraindicated as a restorative filling or core build-up material.
