Dental impressions remain one of the most technique-sensitive procedures in clinical dentistry, and the materials and accessories you choose directly affect accuracy, patient comfort, and lab turnaround. This guide covers every impression material category — alginate, vinyl polysiloxane (VPS), polyether, and bite registration — along with the trays, mixing tips, and dispensing accessories that Canadian practices need to get consistent results in 2026.
As of September 2026, Canadian dental practices perform thousands of impressions annually for crowns, bridges, dentures, orthodontic appliances, and custom trays. Whether your practice is fully digital or still relies on conventional impressions for certain cases, understanding the properties, handling characteristics, and cost structure of each material category helps you make better purchasing decisions and reduce remake rates. EBIKO Dental carries a full range of impression materials and accessories for practices across the Greater Toronto Area (GTA) and Canada, with free shipping on orders over $99 CAD within the GTA, $199 CAD across Ontario, and $299 CAD Canada-wide.
Impression Material Categories: Choosing the Right Material for the Case
Impression materials fall into three primary categories based on their chemistry, each with distinct handling characteristics, accuracy levels, and cost profiles. The material you select should match the clinical indication, your practice's workflow, and the level of detail the laboratory needs.
Alginate (Irreversible Hydrocolloid)
Alginate is the workhorse of preliminary impressions. Made from salts of alginic acid derived from seaweed, it sets through an irreversible chemical reaction when mixed with water. Alginate is the most economical impression material available and is appropriate for study models, diagnostic casts, orthodontic models, custom tray fabrication, and provisional restorations where extreme precision is not required.
Handling considerations for alginate include water temperature (cooler water extends working time), powder-to-water ratio (follow the manufacturer's scoop-and-water measure exactly), and mixing technique (vigorous spatulation against the side of a rubber mixing bowl for 30 to 45 seconds). Alginate impressions should be poured within 10 to 15 minutes to prevent distortion from syneresis (water loss) or imbibition (water absorption).
Pro Tip: Store alginate powder in a cool, dry location and roll the canister before opening to redistribute settled components. Clumpy alginate produces inconsistent mixes that compromise the impression surface.
EBIKO Dental carries Jeltrate Alginate Impression Material ($29.99 CAD), a trusted formulation from Dentsply Sirona that delivers consistent results across a wide range of clinical applications.
Vinyl Polysiloxane (VPS) — Addition Silicone
VPS is the gold standard for final impressions in fixed prosthodontics. Its advantages include excellent dimensional stability (impressions can be poured days or even weeks later without significant distortion), high tear resistance, and fine detail reproduction down to 20 micrometres. VPS materials come in multiple viscosities — from ultra-light body (for wash impressions and sulcular detail) through light body, medium body, and heavy body (for tray material).
The two-viscosity technique — heavy body loaded in the tray with light body syringed around the preparation — remains the most common approach for crown and bridge impressions. VPS sets through a platinum-catalysed addition reaction, which means it does not produce byproducts that cause shrinkage. However, VPS is inherently hydrophobic, so moisture control at the preparation site is essential for accurate results.
EBIKO Dental carries PERFIT Light Body Elastomeric Impression Material ($24.99 CAD), available in Normal Set and Fast Set formulations. The 50 mL cartridge format uses standard automix delivery, reducing hand-mixing variability and ensuring consistent mix ratios every time.
Polyether
Polyether impression materials (the most well-known being 3M's Impregum line) offer a unique advantage: they are inherently hydrophilic, meaning they capture detail even in the presence of moisture. This makes polyether the material of choice for implant impressions and subgingival preparations where achieving a completely dry field is difficult.
The trade-off is rigidity. Polyether sets to a stiff final consistency, which can make removal from undercuts challenging and occasionally uncomfortable for the patient. Polyether is also the most expensive impression material per unit, which limits its use to cases where its moisture tolerance provides a genuine clinical advantage.
Bite Registration Materials
Bite registration materials record the occlusal relationship between the maxillary and mandibular arches. Modern bite registration materials are typically VPS-based (addition silicone) formulated for fast set and high rigidity, ensuring the record maintains its shape during articulator mounting.
EBIKO Dental carries PERFIT Bite Registration A-Silicone ($24.99 CAD) in a 50 mL dual-cartridge format, and Dentsply Regisil VPS Bite Registration Material ($179.99 CAD) for practices preferring the Dentsply system. Both use automix cartridges with standard mixing tips for consistent results.
Impression Trays: Disposable vs. Autoclavable
The impression tray provides the structural framework that supports the material in the mouth. Tray selection affects material distribution, patient comfort, and the overall accuracy of the impression.
Disposable Plastic Impression Trays
Disposable trays are the most economical option and eliminate the need for sterilization between patients. They are appropriate for alginate impressions and preliminary models where absolute rigidity is not critical. EBIKO Dental carries Plastic Impression Trays ($5.99 CAD per 12-pack) — less than $0.50 per tray — in multiple sizes for full-arch and quadrant impressions.
Autoclavable Impression Trays
For final impressions, autoclavable trays provide the rigidity needed to prevent tray flexion during seating and removal. Flexion distorts the impression, particularly in long-span fixed prosthodontic cases. EBIKO Dental carries Autoclavable Plastic Steel Impression Trays ($15.99 CAD per 10-pack) that combine the convenience of plastic with a steel reinforcement framework.
Pro Tip: Apply VPS tray adhesive to the inner surface of your impression tray and allow it to dry for at least 2 minutes before loading the impression material. Adhesive failure is one of the most common causes of impression remakes — the material separates from the tray during removal, distorting the critical marginal area. EBIKO Dental carries VPS Tray Adhesive Refill ($44.99 CAD) for this purpose.
Mixing Tips and Dispensing Accessories
Automix cartridge systems have largely replaced hand-mixing for VPS and bite registration materials in Canadian practices. The cartridge system uses a dual-barrel design where the base and catalyst are extruded simultaneously through a static mixing tip, ensuring a consistent ratio and homogeneous mix every time.
Standard Mixing Tips
Mixing tips are single-use accessories that attach to the cartridge nozzle. They contain an internal spiral element that blends the two components as they pass through. Using a fresh tip for each impression is essential — residual cured material from a previous mix will block flow or create an inconsistent mix.
EBIKO Dental carries Standard Mixing Tips ($26.99 CAD per 50-pack) and Brown Mixing Tips with Clear Core plus Intra-Oral Tips ($26.99 CAD per 50-pack) for practices using brown-cartridge VPS systems.
Intra-Oral Tips
Intra-oral tips attach to the end of the mixing tip and allow the clinician to syringe light-body VPS material directly around the preparation, into the sulcus, and over fine marginal details. They provide the precision needed for wash impressions in the two-viscosity technique.
EBIKO Dental carries Intra-Oral Tips in 4 styles ($9.99 CAD per 100-pack) — an economical accessory that makes a measurable difference in impression quality.
Specialty Mixing Tips
Different cartridge systems use different tip configurations. Crown and bridge temporary material, for example, uses a 10:1 mixing ratio (rather than the 1:1 or 4:1 ratios common in impression materials), requiring a dedicated tip design. EBIKO Dental carries 10:1 Ratio Mixing Tips for Temporary Crown and Bridge Material ($26.99 CAD per 50-pack) to ensure compatibility.
Supporting Accessories
A well-stocked impression station includes more than just the material and tray. These supporting accessories improve efficiency and accuracy:
- EBIKO Dental Micro Applicator Brushes ($12.99 CAD per 400-pack) — for applying tray adhesive, bonding agents, and placing small amounts of material precisely
- Disposable Dappen Dishes ($6.99 CAD per 100-pack) — for holding small quantities of adhesive, etchant, or other liquids during the impression procedure
- Cotton Rolls Size #2 ($18.99 CAD per 2,000-pack) — for moisture control and isolation during impression-taking
- Gauze 2x2 Non-Woven ($24.99 CAD per 5,000-pack) — for wiping preparations and drying the field
Reducing Impression Remakes: Five Common Mistakes
Impression remakes cost time, material, and patient goodwill. The five most common causes of failed impressions — and how to prevent them — are:
- Inadequate moisture control: VPS requires a dry field. Use retraction cord, hemostatic agents, and isolation techniques before injecting the wash material.
- Tray adhesive failure: Apply adhesive and wait for it to dry completely. Rushing this step leads to material separation on removal.
- Old or expired mixing tips: A partially cured tip from a previous session alters the mix ratio. Always use a new tip.
- Premature removal: Wait the full manufacturer-recommended set time. Removing early distorts the material before it reaches full elasticity.
- Improper tray size: The tray should provide 3 to 4 mm of material thickness around the teeth. Too tight causes thin spots; too loose wastes material and compromises support.
Pro Tip: Track your impression remake rate by keeping a simple tally in your practice management system. If remakes exceed 5% of impressions taken, investigate the root cause — the five issues above account for the vast majority of failures.
Cost Management: Impression Supply Budget for a Canadian Practice
Impression supplies represent a meaningful line item in a dental practice's consumables budget. For a general practice performing 20 to 30 crown and bridge impressions per month, the monthly supply cost breaks down roughly as follows:
- VPS cartridges (light body + heavy body): $150 to $300 CAD
- Mixing tips: $25 to $55 CAD
- Intra-oral tips: $10 to $20 CAD
- Impression trays (disposable or autoclavable): $15 to $50 CAD
- Tray adhesive: $20 to $45 CAD (lasts 2 to 3 months)
- Alginate for preliminary impressions: $30 to $60 CAD
- Bite registration material: $25 to $50 CAD
Total monthly impression supply cost: approximately $275 to $580 CAD, depending on case volume and material preferences. Purchasing in bulk from a Canadian supplier like EBIKO Dental — rather than ordering small quantities from multiple sources — reduces per-unit costs and consolidates shipping.

Frequently Asked Questions
Q: What is the best impression material for crown and bridge work in a Canadian dental practice?
Vinyl polysiloxane (VPS), also called addition silicone, is the most widely used impression material for crown and bridge work in Canadian practices. VPS offers excellent dimensional stability, high tear resistance, and fine detail reproduction. It can be poured days or weeks after the impression without significant distortion, making it ideal for practices that ship impressions to an off-site dental laboratory. EBIKO Dental carries PERFIT Light Body VPS at $24.99 CAD per dual-cartridge pack.
Q: How much do dental impression supplies cost per month for a general practice in Ontario?
A general dental practice in Ontario performing 20 to 30 final impressions per month typically spends between $275 and $580 CAD on impression-related supplies, including VPS cartridges, mixing tips, intra-oral tips, impression trays, tray adhesive, alginate, and bite registration material. Buying from a Canadian dental supplier with free shipping thresholds — such as EBIKO Dental, which offers free shipping on orders over $99 CAD in the GTA — helps reduce per-unit costs.
Q: Should I use disposable or autoclavable impression trays for final impressions?
Autoclavable impression trays with steel reinforcement provide the rigidity needed for accurate final impressions in fixed prosthodontics. Tray flexion during seating or removal distorts the impression, particularly for long-span cases. Disposable plastic trays are appropriate for alginate preliminary impressions where absolute rigidity is less critical. EBIKO Dental carries autoclavable plastic steel trays at $15.99 CAD per 10-pack and disposable trays at $5.99 CAD per 12-pack.
