ProBase Cold is a self-polymerizing denture base resin designed for reliable laboratory work. It stands out for its good flow and modelling properties, its versatility in both pouring technique and packing / press technique, and its practical value for adjustments, repairs and relines.
Consistent handling Adjustable working time Clean polishing Repeatable workflow
Ivoclar ProBase Cold resin: a reliable solution for removable prosthetics in the dental laboratory
For laboratories looking for a dependable and versatile cold-curing acrylic resin, Ivoclar ProBase Cold remains a safe choice.
It offers controlled consistency, helps produce clean denture bases, enables efficient denture repairs, and supports predictable relines with a coherent protocol.
Its value is especially clear when you want to reduce handling variations while maintaining a smooth, dense and easy-to-polish finish.
Key benefits for the laboratory
- Self-curing: suitable for cold-processing in many standard removable prosthetic cases.
- Good flowability: facilitates pouring and improves result consistency.
- Comfortable modelling: better control during the plastic phase for laboratory adjustments.
- Flexible workflow: can be used with pouring technique or packing technique depending on workstation organisation.
Why it matters for a dental technician
- Efficient repairs on existing bases and prosthetic modifications.
- Relines to improve fit and functional comfort.
- Coordinated shades with other Ivoclar materials for aesthetic consistency.
- Adjustable consistency thanks to the powder/liquid ratio within the recommended limits.
Applications in the dental laboratory
- Fabrication of removable denture bases in acrylic resin.
- Repair of fractures or extensions on existing dentures.
- Relining to improve fit and comfort in the mouth.
- Adjustments on ProBase Hot, ProBase Cold, SR Ivocap and IvoBase according to material indications.
- Routine laboratory work for complete or partial dentures depending on internal protocol.
Recommended working procedure at the bench
- Carefully prepare the surfaces and isolate the model if required.
- Measure powder and liquid according to the manufacturer’s recommendations.
- Allow the mixture to develop until it reaches the phase suited to your working technique.
- Process using pouring or packing depending on the clinical case and laboratory routine.
- Finish with trimming, finishing and polishing to obtain a clean and stable surface.
What the formulation brings to daily work
A high-performing self-curing resin must offer the right balance between initial flowability, working window and post-curing stability. With ProBase Cold, the practical benefit lies in the possibility of adapting the material behaviour within the usual mixing limits, helping the technician adjust viscosity to the protocol, working pace and geometry of the restoration.
Benefits for finishing and gingival appearance
A more regular surface makes prosthetic resin polishing easier and helps achieve a clean, easy-to-maintain finish.
In practice, this supports delivery of a better-finished denture, with more homogeneous gingival aesthetics and a higher-quality impression when the work is handed over.
How to choose a cold-curing resin for dental prosthetics?
To choose the right cold-curing denture base resin, you should focus on four very practical criteria: mix consistency, flow quality, the ability to handle repairs and relines, and ease of finishing / polishing.
ProBase Cold fits this laboratory logic well because it combines familiar handling, broad suitability for routine removable prosthetic work, and shade consistency within the Ivoclar system.
It is a strong choice when you want a versatile material that is neither too temperamental nor restricted to a single workflow.
Useful compatibilities for the laboratory
- Work on acrylic PMMA denture bases.
- Consistent use within the Ivoclar ProBase environment.
- Adjustments and repairs on ProBase Hot, ProBase Cold, SR Ivocap and IvoBase.
- Suitable for conventional removable prosthetic bench organisation.
When it is particularly useful
- When the laboratory needs a denture repair resin that is easy to standardise.
- When relines must be carried out with a dependable workflow.
- For technicians who want to retain a degree of flexibility over mix consistency.
- For benches where pouring technique remains an important part of the workflow.
Laboratory tips for a clean and repeatable result
- Maintain a constant powder / liquid ratio throughout the whole batch to avoid behavioural variations.
- Always work at the same setting stage to standardise the application phase.
- Avoid surface contamination before repair or relining procedures.
- Use a progressive polishing sequence to optimise gloss without unnecessarily overheating the resin.
- Keep the instructions for use and SDS at the workstation to support safe working practices and internal training.
Surface quality and denture maintenance
A well-finished base is more pleasant to inspect and easier to keep clean.
In the laboratory, a resin that polishes well helps deliver a higher-quality piece, with a smoother feel and better final perception by both the practitioner and the patient.
Benefits for bench organisation
In a real workflow, handling consistency matters as much as the technical sheet.
The fact that ProBase Cold can be processed using both pouring and packing, while also covering repair and relining needs, helps simplify material management on a daily basis.

FAQ — Ivoclar ProBase Cold
What exactly is ProBase Cold used for in the dental laboratory?
ProBase Cold is a self-polymerizing denture base resin intended for routine removable prosthetic work.
It is used for fabricating bases, for denture repairs, for adjustments and for relines.
Its main benefit is to provide consistent cold processing with good suitability for both pouring technique and packing technique.
Is this resin suitable only for fabrication, or also for repairs?
It is also suitable for repairs and adjustments.
Ivoclar states that it can be used on ProBase Hot, ProBase Cold, SR Ivocap and IvoBase within the scope of the intended uses.
This is precisely what makes it valuable for a laboratory seeking a versatile material rather than a resin limited to a single indication.
Why is the possibility of adjusting the consistency useful?
The powder / liquid ratio allows the consistency and working time to be adjusted within the recommended limits.
In practice, this helps the technician adapt the material behaviour more precisely to case size, working technique and pace.
When properly standardised, this flexibility often improves protocol repeatability in the laboratory.
What are the key points for achieving a clean and durable result?
First, you must maintain a consistent mixing ratio and a repeatable mixing method.
Then you should always work at the same setting phase, with surfaces prepared correctly.
Finally, careful finishing and polishing improve surface quality, gingival aesthetics and the final perception of the delivered work.
Which documents should be kept at the workstation for proper handling?
The instructions for use are essential to secure the processing protocol.
The Monomer SDS and Polymer SDS are crucial for safety, storage, PPE and internal laboratory traceability.
Keeping these documents accessible at the bench helps train the team and standardise workflows over time.
