Choosing the right dental cement is one of the most consequential — and most overlooked — material decisions in restorative dentistry. As of August 2026, the cement landscape spans zinc oxide eugenol temporaries, resin-modified glass ionomers, and self-adhesive resin cements, each with distinct bond strengths, handling properties, and clinical indications. This guide breaks down what Canadian dental practices need to know to match the right cement to every restoration.
Walk into any dental operatory and you will find a drawer full of cement cartridges, tubes, and automix syringes. The variety is not accidental — it reflects the clinical reality that no single dental cement works optimally for every restoration type, substrate condition, and patient scenario. A lithium disilicate veneer demands a different cementation strategy than a PFM crown on a vital tooth, which in turn differs from a zirconia bridge on implant abutments.
For dental professionals in Toronto, the GTA, and across Ontario, the cement selection decision also carries a financial dimension. Resin cements and universal adhesive systems come at a meaningful cost premium over glass ionomer alternatives, and unnecessary use of expensive materials on cases that do not require them is a direct hit to your supply budget. Conversely, under-specifying the cement — using a conventional glass ionomer where a self-adhesive resin was indicated — can lead to debonds, re-cementation appointments, and patient dissatisfaction.
Getting this right means understanding the three major cement families, their mechanisms of retention, and their clinical sweet spots.
Category 1: Temporary Cements — Controlled Retrievability
Temporary cements are designed to hold a provisional restoration in place long enough for the definitive prosthesis to be fabricated, while allowing clean removal without damaging the preparation or the underlying tooth structure. The balance between adequate retention and controlled retrievability is the core design challenge.
Zinc Oxide Eugenol (ZOE) Cements
ZOE cements have been the default temporary cementation material for decades, and they remain widely used in Canadian dental practices. The eugenol component provides a mild analgesic and antibacterial effect that can be beneficial on vital tooth preparations. Setting time is generally forgiving, and cleanup is straightforward.
The critical limitation: eugenol interferes with the polymerization of resin-based materials. If your definitive restoration will be bonded with a resin cement — and most ceramic restorations demand this — a ZOE temporary cement can compromise the bond strength of the final cementation. This interaction has been documented extensively, and its practical consequence is real: higher rates of post-cementation debond when eugenol residue remains on the prepared dentin.
Pro Tip: Reserve ZOE-based temporary cements for cases where the final cementation will use a conventional (non-resin) luting agent — such as PFM crowns on vital teeth cemented with glass ionomer. For any case destined for resin cementation, use a eugenol-free alternative.
Eugenol-Free Temporary Cements
Eugenol-free formulations solve the resin-compatibility problem while maintaining reasonable temporary retention. Products like Kerr TempBond Clear use a modified resin or polymer base that provides predictable hold without contaminating the dentin surface for subsequent resin bonding. TempBond Clear, available at EBIKO Dental in a convenient 6 g automix syringe with 10 mixing tips, also contains triclosan for antimicrobial protection during the provisional phase.
For Canadian practices performing significant volumes of indirect restorations — crowns, inlays, onlays, veneers — eugenol-free temporary cement should be the default. The marginal cost increase over ZOE formulations is negligible compared to the risk of a resin cementation failure down the line.
Category 2: Conventional Luting Cements — Retention Without Bonding
Conventional cements rely primarily on mechanical retention (the friction fit between the prepared tooth and the restoration) rather than adhesive bonding to the tooth structure. They work well when the preparation design provides adequate retention form — a well-tapered crown preparation with sufficient axial wall height, for example.
Glass Ionomer Cements (GIC)
Conventional glass ionomers set through an acid-base reaction between fluoroaluminosilicate glass powder and polyacrylic acid liquid. They offer a genuine chemical bond to both enamel and dentin (via ionic exchange with calcium and phosphate), fluoride release that may provide some caries-protective effect, and reasonable strength for retentive crown preparations.
GICs are technique-forgiving and moisture-tolerant, making them practical choices in clinical situations where absolute isolation is challenging. Their limitations include relatively low tensile strength compared to resin-based alternatives, susceptibility to early moisture contamination during setting, and limited aesthetics (opaque finish).
Resin-Modified Glass Ionomer Cements (RMGI)
RMGIs add a light-curable resin component to the glass ionomer matrix, combining the fluoride release and chemical adhesion of conventional GICs with improved strength, reduced early moisture sensitivity, and dual-cure capability. Products like 3M RelyX Luting Plus, available at EBIKO Dental as the RelyX Luting Plus Clicker Dispenser Trial Kit (11 g), offer convenient unit-dose dispensing that reduces waste and ensures consistent mix ratios.
RMGIs are widely considered the workhorse luting cement for metal and PFM crowns in Canadian dental practices. They provide reliable retention on well-prepared teeth, straightforward cleanup, and a forgiving working time. For most routine crown cementation on vital teeth with adequate retention form, an RMGI represents an excellent balance of performance, cost, and clinical predictability.
Pro Tip: When cementing a PFM crown with an RMGI, apply the cement to the internal surface of the crown rather than the preparation. This reduces the risk of hydraulic pressure trapping excess cement subgingivally and gives you better control over marginal cleanup before the material sets.
Category 3: Resin Cements — Adhesive Bonding for Demanding Restorations
Resin cements provide the highest bond strengths of any cementation category and are essential for restorations that rely on adhesive retention — thin ceramic veneers, conservative inlays and onlays, and all-ceramic crowns with minimal preparation taper. They are also the material of choice for fibre post cementation and for luting restorations to compromised preparations with limited mechanical retention.
Conventional Resin Cements (Etch-and-Rinse or Self-Etch)
These systems require a separate adhesive application step before the cement. Products in the Kerr OptiBond FL family are widely regarded as the benchmark for adhesive resin cementation, offering exceptionally high dentin bond strengths when used with proper isolation and technique. OptiBond FL's two-bottle etch-and-rinse system remains the research gold standard against which newer simplified adhesives are compared.
For universal bonding applications, the Kerr OptiBond Universal provides the flexibility to work in etch-and-rinse, self-etch, or selective-etch modes from a single bottle — simplifying inventory and adapting to different clinical scenarios. The OptiBond Solo Plus refill (5 ml) offers an additional option for practices already invested in the OptiBond system.
The trade-off with conventional resin cements is technique sensitivity. Moisture contamination, inadequate etching, or poor adhesive application can dramatically reduce bond strength. These materials demand proper isolation — ideally rubber dam, which is itself available as the rubber dam sheet 36-pack at EBIKO Dental — and a methodical cementation protocol.
Self-Adhesive Resin Cements
Self-adhesive resin cements combine the bond-strength advantages of resin chemistry with a simplified one-step application that eliminates the need for separate etching, priming, and bonding. Products like Kerr Maxcem Elite and 3M RelyX Universal Resin Cement have made adhesive cementation accessible for a broader range of clinical scenarios, including cases where perfect isolation may be challenging.
Self-adhesive resin cements are particularly valuable for cementation of zirconia restorations, where their chemical bonding to the zirconia surface (often enhanced by a zirconia primer) provides reliable long-term retention without the complexity of a multi-step adhesive protocol. They are also excellent choices for fibre post cementation, implant-supported crown cementation (where retrievability may be desirable), and any situation where a simplified workflow reduces the risk of procedural errors.
Pro Tip: For high-strength zirconia crowns and bridges, a self-adhesive resin cement paired with a zirconia-specific primer (such as a product containing 10-MDP) typically provides the best combination of bond strength and clinical practicality. The additional cost of the primer is minimal and the retention improvement is significant.
Matching Cement to Restoration: A Practical Framework
Rather than memorizing individual product specifications, build your cementation decision around these principles:
- All-ceramic veneers and ultra-thin restorations: Adhesive resin cement with separate bonding agent (light-cure mode preferred for veneers to allow complete seating before polymerization).
- Lithium disilicate crowns and inlays: Self-adhesive or conventional resin cement, depending on preparation retention. HF-etch the ceramic intaglio surface and apply silane before cementation.
- Zirconia crowns and bridges: Self-adhesive resin cement with zirconia primer, or RMGI for retentive preparations where cost optimization is a priority.
- PFM crowns on vital teeth: RMGI is the standard. Reserve resin cements for cases with questionable retention.
- Full-cast metal crowns: RMGI or conventional GI. Resin cements are rarely necessary given the mechanical retention of metal castings.
- Implant-supported cement-retained crowns: Self-adhesive resin cement at reduced film thickness. Consider screw retention first to avoid the cement-related peri-implant complication risk.
- Fibre posts: Self-adhesive resin cement or dual-cure adhesive resin cement. Ensure full-depth curing — consider a dual-cure activator if the post canal length exceeds 8–10 mm.
Cost Considerations for Canadian Practices
Dental cements range from under $1 CAD per unit of use for conventional glass ionomers to $8–15 CAD per unit for premium resin cement systems with their associated adhesives and primers. Over the course of a year, a busy restorative practice performing 15–20 crown cementations per week can spend $5,000–$15,000 CAD on cementation materials alone, depending on the product mix.
The cost-optimization strategy is not to default to the cheapest option for every case — that invites clinical failures — but to reserve premium resin cements for cases that genuinely require adhesive retention, and to use cost-effective RMGIs or conventional cements where retention form is adequate. This approach can reduce cementation material costs by 30–40% without compromising clinical outcomes.

Frequently Asked Questions
Q: Can I use the same cement for both zirconia and lithium disilicate restorations?
A self-adhesive resin cement can work for both, but the surface treatment of the restoration differs. Zirconia requires sandblasting or a zirconia-specific primer containing 10-MDP for chemical bonding. Lithium disilicate benefits from hydrofluoric acid etching followed by silane application to create micromechanical and chemical retention. Using the same cement is fine — the surface preparation is what changes between materials.
Q: Why does eugenol in temporary cement matter for my final cementation?
Eugenol is a phenolic compound that inhibits the free-radical polymerization reaction in resin-based cements and adhesives. Even trace amounts of eugenol remaining on the dentin surface after temporary cement removal can reduce the bond strength of the definitive resin cementation by 30–50%, increasing the risk of early debond. If your final restoration will be bonded with any resin-based material, use a eugenol-free temporary cement during the provisional phase.
Q: What is the shelf life of dental cements, and does it matter in a Canadian climate?
Most dental cements have a shelf life of 2–3 years from manufacture when stored according to the manufacturer's instructions — typically at room temperature (15–25°C) away from direct sunlight. In Canadian practices, the main storage concern is temperature extremes during shipping in winter months. If a cement shipment was exposed to freezing temperatures during transit, check with the manufacturer before use, as freeze-thaw cycles can alter the rheological properties and setting characteristics of some formulations. Ordering from a Canadian-based supplier like EBIKO Dental reduces transit time and the risk of temperature-related product degradation.
