Express™ 2 VPS Impression Materials
Technical Data Sheet
3M ESPE – More than 40 Years of Experience in Impressioning
As the world market leader for impression materials 3M ESPE is renowned for its innovative
solutions. Since the introduction of the first impression material more than 40 years ago,
3M ESPE has continuously improved and enlarged its product portfolio: Polyether and VPS
impression materials meet virtually all customer needs and preferences, ranging from
different impression techniques and indications to delivery choices.
Based on an advanced VPS formula, Express 2 VPS Impression Materials, the next generation
of VPS from 3M ESPE, sets the stage for uncompromising impression accuracy and a great fit
of indirect restorations. In a variety of viscosities – from putty to ultra-light body – Express 2
VPS Impression Materials offer essential benefits for the 1-step and 2-step technique. All
Express 2 tray materials are mixed automatically in the Pentamix™ 2 Mixing Unit. Putty users
also benefit from automatic mixing. Express 2 wash materials are very hydrophilic and show
great flow properties. To minimize the risk of tearing and distortions upon removal, Express 2
wash materials have a high elongation potential and a high tensile strength. Beyond that they
recover nearly 100 % from deformations during mouth removal.
Meets All Requirements of Dental Practice and Lab
Express 2 VPS Impression Materials provide a first-class foundation for accurately fitting
restorations – saving time and increasing comfort for dentist, dental technician and patient.
This has been confirmed by 3M ESPE internal tests where Express 2 showed its winning
combination of clinically relevant properties compared to other leading VPS Impression
Materials.
Indications
All precision impressions, e.g. for crowns, bridges, inlays and onlays. The fast setting
Quick products are especially suited for small restorations (1 or 2 units).

Toughness can be easily explained by comparison with a bungee jumper who has to rely on his rope. The rope needs to elongate but must not tear.
Capture tooth and preparation margin in detail through strong hydrophilicity and very good flowability.
Necessary Characteristics of an Impression Material to Withstand Mouth Removal:
• Ability to elongate and compress 4elongation and compression potential
• Ability to avoid tearing 4high tensile strength
• Ability to recover from elongation and compression 4recovery from deformation
The overall goal of an impression is to create an exact copy of the intraoral situation especially the detailed reproduction of
the preparation margins – a prerequisite for excellent fitting restorations. To capture the margin, an impression material
needs to have excellent properties in the unset stage, especially hydrophilicity and flowability. To avoid any kind of perma-
nent deformation when the impression is removed from the mouth, an impression material needs superior properties in
the set stage. The new Express™ 2 VPS Impression Materials meet these requirements – even under challenging clinical
conditions – the first time.
Focus on Clinically Relevant Material Properties
Flow to tooth and gingiva of Express™ 2 Light Body Flow (green) and Express™ 2 Light Body Standard (lavender) wash materials. The more flowable Express 2 Light Body Flow creates a very smooth surface, whereas Express 2 Light Standard exhibits more structure.
Hydrophilicity: Great Detail Reproduction Even in the Presence of Moisture
The hydrophilicity of an impression material contributes to the reproduction of detail in a moist environment. The method
most often used to determine the hydrophilicity of an impression material is the contact angle measurement: A drop of water
is placed on the surface of an impression material, the spreading of the drop is observed and the contact angle is measured.
The lower the contact angle – the better the hydrophilicity. In 3M ESPE internal comparative tests Express 2 wash materials
showed a much lower contact angle than all the other VPS materials tested. Clinically this reflects the potential for superb
wettability of the preparation surfaces. Therefore Express 2 Impression Materials offer very good detail reproduction, even
under challenging clinical conditions.
When an impression is removed from the mouth, it is exposed to two principal forces, elongation and compression.
Compared to other VPS impression materials, Express™ 2 VPS Impression Materials have an unique ability to withstand
these deformation forces.
Distortion-Free Removal from Mouth and Model
Toughness: The Potential to Resist Tearing!
To avoid tearing while the set impression is removed from the mouth, an impression material does not only need to have
a high tensile strength but also a high elongation potential that allows the material to stretch.
The combination of these two parameters is described as toughness. It is defined as the total amount of energy an impression
material can absorb until it tears. Therefore toughness is the best measure of an impression material’s ability to withstand
the forces it is exposed to – during mouth removal and when the model is fabricated – without tearing.
Toughness values for different VPS wash materials of same setting version (regular) and comparable viscosity. Express™ 2 Light Body Standard exhibits noticeably higher toughness values than Aquasil Ultra LV, President Plus Jet light and Affinis Regular Body.

Flowability: Reliable Coverage of Preparation Surface
Upon syringing impression wash materials require special flow properties
to ensure optimal coverage of the preparation surface areas.
Express™ 2 Wash Materials come in different viscosities. Express™ 2
Light Body Flow (-Quick) VPS Impression Material offers a great flow
to the tooth surfaces and gingiva while still retaining sufficient drip
resistance. Upon syringing, the material flows very well into the sulcus
by itself. Express™ 2 Light Body Standard (-Quick) VPS Impression
Material is slightly more viscous. It stays nicely on the tooth while still
offering good flow characteristics.

Recovery from Compression and Elongation
Precision impression materials all fulfil the minimum requirement for recovery from compression of 96,5 %
(ISO test). Typically the materials show values of > 99 % in this test, meaning a permanent deformation
of 1 % or even less. But how about their recovery from elongation? High recovery from elongation is
important for the area around the preparation margin, especially in clinical situations with a deep
sulcus, undercuts and interproximal spaces. In these places the impression material is exposed to
strong elongation forces during removal from the mouth.
The results of a 3M ESPE internal comparative study on the recovery from elongation
demonstrate the superb performance of Express™ 2 VPS Impression Materials. In this
test, paddle shaped test specimens of different VPS materials were cured at mouth
temperature, according to the manufacturers’ recommended setting times, then they
were stretched by 150 % and allowed to recover. Two hours after stretching, the
samples were measured to determine the recovery from elongation. Results
showed that Express™ 2 Light Body Standard VPS Impression Material recov-
ers nearly 100 % after stretching. Its permanent deformation is only
0,25 %. In contrast Aquasil™ Ultra LV exhibits a large perma-
nent deformation of 2,2 % (Lot: 041030). Clinically
this means that even exposed to strong elonga-
tion forces, Express 2 Light Body Standard can
maintain its original dimensions, whereas
impression materials with considerably lower
recovery after elongation (e.g. Aquasil™
Ultra LV) may experience a permanent deformation – potentially
leading to distortions and therefore to poor fit of restorations.
Important for Dental Practice and Lab
The nearly 100% recovery from elongation of Express 2 VPS Impression Materials is also an important advantage for the
dental technician. While the impression is removed from the cast, it is again exposed to elongation and compressive forces.
To benefit from multiple pouring of VPS impressions, superb recovery from deformation is essential.
The winning combination of clinically relevant characteristics are:
• Tensile strength
• Elongation potential
• Toughness
• Recovery from elongation
• Hydrophilicity.
The above mentioned clinical benefits of Express™ 2 VPS Impression Materials can be summarized in a star chart:
Great Performance where it clinically counts
Express™ 2 Light Body Standard VPS Impression Material (green) shows very convincing performance in this compilation
of clinically important properties. It is the only material that performs very well in each of the five tested properties,
whereas all the other tested materials show weaknesses at least for one property.
This outstanding balance of properties of Express™ 2 VPS Impression Material offers excellent potential for highly accurate
impressions and better fitting restorations – a benefit for dentist, patient and dental technician.
Very Positive Feedback from Dental Practitioners
In a clinical test of the new Express 2 VPS Impression Materials with
87 dentists from Germany, France and Italy 1125 precision impressions
were taken, 57 % with the 1-step technique and 43 % with the 2-step
technique. Overall, dentists were very satisfied with the Express 2 VPS
Impression Materials and judged them to be very good across a wide
variety of material characteristics and slightly better than their currently
preferred products.

The Ideal Combination for 2Step Technique
Offering high final rigidity and very good carving properties, Express 2 Penta Putty VPS Impression Material is a convincing
choice for the 2-step putty-wash technique in combination with the wash material Express™ 2 Ultra-Light Body Quick VPS
Impression Material. Due to its ultra-light consistency combined with its strong structural viscosity this wash material is able to
flow very well into the sulcus. It also generates very thin layers in the first impression when applied under pressure. Express 2
Ultra-Light Body Quick thus helps reducing the risk of displacing the tray material, a problem typical for the 2-step technique
that occurs if the wash material builds up thick layers in the first impression, displaces it and then sets.
Express™ 2 Penta™ Putty VPS Impression Material combines classical
putty benefits, appreciated by many dentists – like high insertion
pressure and malleability – with the advantages of automatic mixing
in the Pentamix™ 2 Mixing Unit. The Pentamix 2 Mixing Unit offers
homogeneous and void-free consistent mixing quality as well as easy
and clean handling. Superior mixing quality of Express™ 2 Penta™ Putty with the Pentamix™ 2 Mixing Unit (green test specimen) compared with a putty mixed by hand (orange test specimen, Express™ Putty Standard)
Long Working Time and Fast Setting for 1Step Technique
For the 1-step technique the somewhat thicker and less structural viscous
wash material Express 2 Light Body Standard is recommended. For this
impression technique Express 2 Penta Putty offers a unique benefit: It
accelerates the intra-oral setting time of any VPS wash material. This
thermally active behaviour results from the fact that the putty already
has mouth temperature when dispensed from the Pentamix 2 Mixing
Unit. Therefore the VPS wash material warms up faster accelerating its
polymerisation which is strongly temperature dependent. The intra-oral
setting time is shortened, whereas the working time of the VPS wash
material remains unchanged. Dentists benefit from a long syringing time
in combination with a shorter setting time, which increases productivity
and patient comfort.

Real Putty with High Insertion Pressure
Like its predecessor Express Penta Putty the new Express 2 Penta Putty offers a true putty viscosity. 3M ESPE internal
and external comparative tests have shown that the insertion pressure of Express Penta Putty corresponds to that of typical
handmix putties and is much higher than the insertion pressure of heavy body VPS tray materials (internal tests 3M ESPE,
external study Prof. Wöstmann, Justus-Liebig-University Giessen, Germany – unpublished data).
