Dreve Modralit® 3K – high-precision polyurethane resin for implant models and dental dies
Modralit® 3K Dreve is a three-component polyurethane resin designed for the fabrication of very high-precision dental models, particularly for implant work, laboratory dies, master models and superstructures.
With an extremely low expansion of 0.07%, high hardness and excellent mechanical resistance, it is a premium alternative to class 4 dental stones when dimensional stability is a priority.

A precision resin for the most demanding dental models
For implant work, precision dies and complex restorations, the quality of the model directly determines the reliability of the fit. Dreve Modralit® 3K has been designed to meet this requirement with superior dimensional stability and a dense, homogeneous and resistant surface.
Unlike a standard plaster model, polyurethane resin significantly reduces wear on handled areas. Edges remain better defined and the model maintains higher precision throughout the design, fitting, checking and finishing stages.
It is intended for dental prosthesis laboratories looking for a reliable working base in cases where even the smallest dimensional discrepancy can compromise the passivity or accuracy of the final restoration.
Dimensional stability for implantology
Implant models require faithful reproduction of the clinical situation. Excessive expansion can alter distances, disturb axes or influence the fitting of frameworks and structures.
- Very low linear expansion: 0.07%.
- Stability suitable for implant models.
- Reliable working base for superstructures.
- Useful precision for implant bars.
- Master models more resistant to handling.
Superior resistance for dies and master models
Dies and master models are handled many times during fabrication. The mechanical resistance of Modralit® 3K helps limit wear on critical areas.
- Dense and homogeneous surface.
- Very good detail reproduction.
- Limited die wear.
- Edges better preserved during work.
- High-end alternative to conventional dental stones.
Applications in the dental prosthesis laboratory
Dreve Modralit® 3K polyurethane resin is particularly suitable for work where model precision must remain stable despite repeated handling.
- Implant models: fabrication of reliable master models for implant work.
- High-precision dies: preparation of dies resistant to wear and handling.
- Implant bars: stable working base for frameworks and superstructures.
- CAD/CAM work: reference models for digital laboratories.
- Combined prosthetics: cases requiring excellent fitting precision.
- Heavily handled models: situations where the model must retain its definition over time.
Why choose Modralit® 3K rather than dental stone?
Class 4 dental stones offer very good precision for many indications. However, some implant or combined cases require an even higher level of stability and resistance.
Modralit® 3K stands out for its very low expansion, wear resistance and the quality of the surface obtained. It allows the laboratory to keep a usable reference model throughout the fabrication process, even when the case requires numerous try-ins or checks.
For precision
- Expansion reduced to 0.07%.
- Faithful detail reproduction.
- High dimensional stability.
- Reliable base for implant work.
For model durability
- Superior mechanical resistance.
- Limited die wear.
- Better resistance to repeated handling.
- Dense and regular surface.
Working recommendations
To obtain a precise and homogeneous model, it is important to follow the manufacturer’s recommendations for preparation, dosing and polymerisation.
1: Prepare the three components and mix them carefully according to Dreve’s recommendations.
2: Pour the resin slowly into the impression, ideally on a vibrator, to limit air bubbles.
3: Observe the setting time of approximately two hours before demoulding or first handling the model.
4: Prepare and adjust the model according to the usual laboratory procedures, then apply a die spacer if required.

A solution suitable for digital laboratories
Laboratories working with CAD/CAM need reliable models for checking, fitting and validating restorations. A stable model helps secure the stages between digital design and physical finishing.
Modralit® 3K is particularly useful when the model serves as a reference for complex or implant restorations requiring high reproducibility.
Compatible with laboratory die spacers
The dense and homogeneous surface obtained with Modralit® 3K allows the application of die spacers in standard laboratory procedures.
This compatibility makes it easy to integrate the product into existing methods, particularly for restorations requiring controlled spacing.
Modralit® 3K polyurethane resin VS class 4 dental stone
The choice between plaster and resin depends on the type of work. For standard models, a quality dental stone may be sufficient. For implant work, heavily used dies or high-precision cases, polyurethane resin provides additional security.
Modralit® 3K allows the laboratory to work on a more resistant support, less sensitive to wear and more dimensionally stable.
Laboratory use comparison
| Criteria | Class 4 dental stone | Dreve Modralit® 3K |
|---|---|---|
| Standard work | Very suitable for many indications | Best reserved for cases requiring greater precision and resistance |
| Implant work | Precise, but more sensitive to handling constraints | Very low expansion and better dimensional stability |

FAQ – Dreve Modralit® 3K
Why use a polyurethane resin for an implant model?
A polyurethane resin such as Modralit® 3K offers very low expansion and high mechanical resistance.
For implant models, this stability is important because frameworks, bars and superstructures require precise fitting. The resin limits dimensional variations and better withstands repeated handling than a more fragile model.
Does Modralit® 3K always replace dental stone?
No, dental stone remains perfectly suitable for many laboratory situations.
Modralit® 3K is especially useful for cases where precision, dimensional stability and model resistance are priorities: implantology, precision dies, master models, heavily handled work or complex restorations.
What is the setting time of Modralit® 3K?
The indicated setting time is approximately 2 hours before demoulding or handling the model.
It is recommended to follow the manufacturer’s preparation instructions, particularly the dosing of the components and the working conditions, in order to obtain a homogeneous and precise model.
Is Modralit® 3K compatible with die spacers?
Yes, the surface obtained with Modralit® 3K is compatible with standard die spacers used in the laboratory.
This compatibility allows the resin to be integrated into the usual die preparation and restoration fitting procedures.
How many models can be produced with one kit?
The indicated yield is approximately 10 models per kit.
This number may vary depending on the size of the impressions, the volume of resin used for each model and the preparation method applied in the laboratory.
Should the impression be prepared before pouring?
Yes, correct preparation of the impression contributes to the precision of the final result.
When necessary, wax boxing can be carried out before pouring in order to better control the volume and help obtain a clean, usable model.
A premium resin for high-precision implant models
Dreve Modralit® 3K is a preferred solution for dental prosthesis laboratories looking for models that are more resistant, more stable and better suited to demanding implant work.
Its very low expansion of 0.07%, dense surface and mechanical resistance make it a particularly relevant material for dies, master models, implant bars, combined prosthetics and CAD/CAM work.
For cases where model precision directly influences the quality of the final fit, Modralit® 3K provides greater technical security than conventional modelling materials.
