Karadent by TCS: Shades, Sizes and When to Use It

Karadent by TCS is a semi-rigid thermoplastic that comes in three shades (Standard Pink, Dark Pink and Natural/Clear) and in small, medium and large cartridges in 22mm, 25mm and 28mm diameters, plus bulk. Labs use it when a case needs more stability than a fully flexible partial: full dentures, semi-flexible partials, clear clasps, frameworks and nightguards. Karadent is made by TCS (Thermoplastic Comfort Systems), and Chase Dental Supply carries the Karadent cartridge and bulk lineup.

Below, we break down the Karadent by TCS shades and sizes, which cartridge fits your injector, and when Karadent is the better call than Unbreakable or iFlex.

Key Takeaways

• Karadent is semi-rigid, giving the stability of an acrylic and metal partial with the aesthetics of a thermoplastic.
• Three shades: Standard Pink (2), Dark Pink (4) and Natural, sold as Clear (N).
• Cartridges come in Small, Medium and Large; diameters are 22mm, 25mm and 28mm, plus a Large 25mm cartridge with a nozzle tip.
• The 25mm cartridges fit all TCS injectors and most injectors on the market, and are the most popular size.
• Bulk Karadent is available in 500 gram and 1 kilo packs for labs that fill their own cartridges.

What is Karadent by TCS?

Karadent by TCS is a semi-rigid, microcrystalline polymer thermoplastic used to injection mold removable appliances. TCS positions it as an upgrade from acrylic dentures, offering the stability and simplicity of acrylic and metal partials without compromising aesthetics.

It sits between the two other TCS resins. TCS Unbreakable is a flexible nylon and iFlex is a flexible polyolefin, while Karadent is stiffer, which makes it suitable for appliances that need to hold their shape.

What is Karadent used for?

TCS lists Karadent as ideal for these applications:

• Full dentures
• Semi-flexible partial dentures
• Clear clasps
• Frameworks
• Nightguards

That range makes Karadent useful for labs that want one thermoplastic for both prosthetic and appliance work. If you also make conventional splints, compare it with the materials in our Keystone night guard and splint materials guide.

Which Karadent shade should I choose?

Choose Standard Pink for most denture and partial bases, Dark Pink for patients with darker tissue, and Clear for clear clasps or appliances where a pink base is not wanted. Each shade is sold in cartridges and bulk.

Standard Pink (Shade 2)

The default shade for denture bases and semi-flexible partials. Most labs keep Karadent Large Standard Pink 25mm cartridges on hand, along with Karadent Medium Standard Pink 25mm for mid size cases.

Dark Pink (Shade 4)

A deeper tone for patients whose tissue reads darker than Standard Pink. Karadent Medium Dark Pink 25mm is a common pick, and Dark Pink is the only Karadent shade we carry in all three medium diameters.

Natural, sold as Clear (Shade N)

TCS’s spec sheet names Shade N “Natural,” and the product listings call it Clear. It is the shade to use for clear clasps and nightguards, available in cartridges such as Karadent Large Clear 25mm and in bulk.

Which Karadent cartridge size fits my injector?

If you run TCS equipment, order 25mm cartridges, because they fit all TCS injectors and most injectors on the market. The 22mm and 28mm sizes are for labs running other injection units, so check your manufacturer’s instructions first.

Small, Medium and Large refer to how much material the cartridge holds. Match the size to the case: small for limited partials, large for full dentures and larger frameworks. The table shows what Chase Dental Supply carries by shade.

Each cartridge pack includes 5 delivery bags, 5 patient care instructions and 5 samples of TCS Dental Appliance Cleaner (1 week supply), so the lab can send each case out with patient materials.

Karadent vs Unbreakable vs iFlex: when should you use Karadent?

Use Karadent when the appliance needs rigidity: a full denture, a framework, a nightguard or a semi-flexible partial. Use Unbreakable or iFlex when the goal is a fully flexible partial with tissue colored clasps.

• Karadent: semi-rigid microcrystalline polymer for full dentures, semi-flexible partials, clear clasps, frameworks and nightguards.
• TCS Unbreakable: nylon thermoplastic for flexible removable partials.
• TCS iFlex: polyolefin thermoplastic for flexible removable partials, easy to finish and polish.

For a broader look at when a thermoplastic beats a conventional appliance, read flexible partials vs acrylic partials.

How do you buy Karadent in bulk?

Labs that prefer to fill their own cartridges can buy Karadent in 500 gram and 1 kilo bulk packs in all three shades. This suits higher volume labs that already stock empty cartridges and caps.

Karadent Dark Pink, 1 kilo and Karadent Clear, 500 grams are two of the bulk options. Processing steps, including injection temperatures, come from TCS’s instructions for use; our TCS injection system guide covers the equipment side.
