Initial Situation
A decade ago, dental materials were typically produced by using laborintensive,
conventional fabrication methods. Techniques like pressing
fused ceramic into a prepared wax mold, condensation, or casting
processes were standard practice. Today's milled ceramic solutions are
valuable for specific clinical applications but require substantial investment
in equipment and maintenance. The globally increasing demand
for high-quality and affordable prosthodontics called for a more efficient,
accessible solution.
Motivation Behind and
Development of a 3D Printing Resin
Based on our more than 35 years of experience in light-curing dental
materials we wanted to developed a solution that meets the specific
needs of dentists, technicians and patients. In close collaboration
with the University of Zurich, we created a resin for the 3D-printing
of permanent crowns, inlays, onlays, veneers and artificial teeth. The
resin for permanent solutions has been certified CE and validated for
more than 40 printers to date. At SAREMCO safety and biocompatibility
are fundamental. By achieving outstanding physical properties
and replacing problematic monomers with safer alternatives, we ensure
high standards in dental materials. saremco print CROWNTEC
enables dental professionals to produce high-quality prostheses efficiently,
reducing both production time and costs.
Solution saremco print CROWNTEC
The medium-viscosity, light-curing composite resin saremco print
CROWNTEC enables high-precision 3D printing, ensuring minimal material
consumption and optimal adaptation to specific design requirements.
Compared to traditional milling systems, 3D printing requires a less complex
setup, with fewer components and reduced material waste, offering a more
cost-effective and flexible approach while achieving the same level of
precision in dental restorations. 1 To ensure consistent quality, we officially
validate the 3D printing workflow with saremco print CROWNTEC, focusing
on reproducibility and reliability throughout the entire process. Each step of
production is guided by pre-calculated CAD designs, resulting in a product
that consistently meets stringent standards. In extensive tests by research
teams worldwide, saremco print CROWNTEC demonstrated outstanding
performance, with results published in leading dental journals. One key
advantage is its significantly reduced marginal gap compared to conventional
CAD-millable block materials, contributing to a superior fit and long-term
reliability. 2-4 Another strength of saremco print CROWNTEC is its ability to
withstand prolonged stress. In chewing simulations equivalent to five and ten
years of use, the resin showed excellent durability and minimal material wear. 5-6
Even thin, precisely printed layers retained their strength, delivering
bite force performance that remains competitive over time. 6 With
saremco print CROWNTEC, dental professionals have a scientifically
supported material that combines ease of use with lasting quality, optimizing
functionality and aesthetics.

Studies and Measurements
Precision Engineered for Performance
Physical properties of a material are crucial to the success of dental restorations, as they ensure predictable and long-lasting outcomes.
Dental restorations are constantly exposed to:
• Mechanical stress: Chewing forces that can lead to fractures.
• Moisture: Saliva, acids and other fluids that may weaken materials.
• Temperature fluctuations: Daily exposure to hot and cold, which can compromise stability.
FLEXURAL STRENGTH
155 MPa (Requirements 100 MPa)
Flexural strength reflects the material’s
ability to withstand mechanical forces without
breaking. Specimens (2x2x25 mm rods) are
tested after curing and 24-hour water storage at
37°C (ISO 4049), simulating oral conditions.
saremco print CROWNTEC achieves 155
MPa, significantly outperforming most
competitors (<130 MPa) and even traditional
dental alloys (<100 MPa).
FRACTURE RESISTANCE 9
>4000 N
E-MODULUS
>4000 MPa
The E-modulus quantifies the material’s
stiffness and ability to resist deformation.
While higher filler content could increase
stiffness, it would compromise elasticity.
saremco print CROWNTEC balances these
properties to provide strength without
brittleness, ensuring clinical reliability.
BARCOL HARDNESS
50
This value indicates resistance to
penetration, which is essential for wear
resistance. A score of 50 ensures
durability in demanding clinical
conditions.
saremco print CROWNTEC achieves superior
values compared to competitor materials. It
performs close to the dental industry standards
for subtractively manufactured materials.
OPTIMIZED VISCOSITY
~ 1800 cP
The resin’s flowability ensures easy
handling and precise reproduction of
intricate geometries, reducing the need
for adjustments during finishing.

Backed by Rigorous Testing and
Compliance with ISO Norms

Aesthetic Excellence Backed by Science
Aesthetics in restorative dentistry go beyond appearance—they are essential for ensuring patient satisfaction and clinical success.
However, achieving and maintaining long-lasting aesthetics can be challenging due to:
• Discoloration: Caused by light exposure, moisture, and environmental factors.
• Water absorption: Leading to staining and material degradation.
• Surface roughness: Increasing plaque accumulation and reducing natural appearance.
LOW WATER SORPTION
<10 µg/mm³
Low water sorption prevents material
swelling, discoloration, and degradation. With
values well below the ISO limit of 40 µg/mm³,
saremco print CROWNTEC ensures excellent
long-term stability. By minimizing water uptake,
the material resists discoloration and retains its
optical properties, ensuring long-term
aesthetic integrity.
COLOR STABILITY
ΔE < 2.0
Color stability is critical for natural-looking
restorations. saremco print CROWNTEC maintains
a ΔE value of less than 2.0, even under prolonged
exposure to light and moisture, ensuring predictable
shade matching over time (ISO 7491).
WATER SOLUBILITY
0.6 µg/mm³
Water solubility measures how much material
dissolves in water, impacting biocompatibility
and longevity. Our resin conforms to ISO
requirements (<7.5 µg/mm³), with a negligible
elution value of 0.6 µg/mm³.
SMOOTH SURFACE
FINISH
Post-curing, the material achieves a
smooth surface that reduces plaque
accumulation, enhancing both
aesthetics and oral hygiene.

Color Stability
saremco print CROWNTEC demonstrates reasonable discoloration after coffee thermocycling, comparable to subtractively
manufactured resin materials. This ensures long-term aesthetic reliability for definitive dental restorations.

resin-based materials for definitive restorations.» Int. J. Prosthodont 37 (2024): 143-150.
Polishing Technique and Coffee Thermocycling on Color Stability
saremco print CROWNTEC shows much lower discoloration than additively manufactured competitor products, close to
subtractively restorations. This result was surprisingly positive due to the fact that the applied polishing techniques in this paper
were not suitable for saremco print CROWNTEC.

manufactured resins used for definitive restorations.» Journal of Prosthodontics 33.5 (2024): 467-474.
Translucency
Studies show that 3D-printed resins exhibit varying levels of translucency based on printing parameters. Among the investigated
materials, saremco print CROWNTEC demonstrated the least translucency at a 25-micrometer printing thickness, making
it an ideal choice for cases requiring opacity and aesthetic precision in dental restorations.

Bacterial Adhesion
To evaluate bacterial adhesion, saremco print CROWNTEC was immersed in mucin-containing artificial saliva in addition to
the other composite specimens. There was no statistically significant difference in contact angle values between the groups
(p > 0.05). All composite resin samples have hydrophobic properties.

Biocompatibility: Best Values for saremco print CROWNTEC
No Elution of Methacrylates 18
Solubility of methacrylates is of great importance in terms of biocompatibility. Since they are considered to be
substances with high allergic potential. These and other substances released from dental materials find their way -
more or less uncontrolled - into the human organism and can lead to undesired biological reactions.
A quantitative analysis of elutable components of saremco print CROWNTEC had been carried out.
The solvents to be used in the study were distilled water and methanol. The printed and post-cured samples of
saremco print CROWNTEC were examined for their elution behavior by gas chromatography mass spectrometry.
«The higher the number of elutable methacrylates and the higher the amount of eluted methacrylates from dental
materials, the higher the likelihood that sensitive patients may develop an allergy. In this 3D resin, no methacrylate
could be detected in both aqueous and methanolic eluate.»
Cytotoxicity: no Cell Damages 19-20
The test material extracted caused no toxicological/biological critical cell damages and growth inhibition. The test
material meets the requirements of DIN EN ISO 10993-5 and is considered non-cytotoxic. 19
Cytotoxicity Assessment
Human gingival fibroblasts (HGFs) cultured with extracts from saremco print CROWNTEC exhibited a
relative metabolic activity exceeding 70% compared to the negative control. Additionally, the relative lactate
dehydrogenase (LDH) release remained below 30%. Results of this confirm that saremco print CROWNTEC
did not show any cytotoxic effects, either in the extract or in the direct test. 20

Acute Irritation/Intracutaneous Reactivity 21
The polar and apolar extracts of test material, as per ISO 10993-10, did not cause any intracutaneous reactivity
under selected test conditions.
Skin Sensitization Study 21
Based on the obtained values of the negative control group (stimulation index = 1), whose application
solutions are not considered sensitizing, no sensitizing effects, as per ISO 10993-10, could be demonstrated
for all three concentrations of the test specimen extracts. The average value of each group of test specimen
extract concentrations is below the threshold value, above which a substance is classified as sensitizing
(stimulation index = 1.6). These results are supported by the values of the positive control group, given that a
sensitizing substance with a known sensitizing effect could successfully be demonstrated in the employed animal
model. According to DIN EN ISO 10993-10, the test material is classified as non-sensitizing.
