Our innovative A-silicone features an extremely short intra-oral setting time. Active self-warming is the key, a unique chemical reaction developed by 3M ESPE. It causes the material to actively and quickly warm up to body temperature after the working time which leads to accelerated setting.

For you and for your patients Imprint™ 4 VPS Impression Materials ensures:

  • Short intra-oral setting time for real time savings.
  • Sufficient working time for a stress-free procedure
  • Super-hydrophilicity for excellent flow and finest detail reproduction.

Features & Benefits

Imprint™ 4 - the innovative A-silicone precision impression material – offers you:

  • Active self-warming for accelerated setting.
  • Very short intra-oral setting time for real time savings.
  • Sufficient working time for a stress-free procedure
  • Super-hydrophilicity for excellent flow and finest detail reproduction.

The impression material with active self-warming

Imprint™ 4 VPS Material features a very short intra-oral setting time of just 75 seconds achieved by active self-warming. A unique chemical reaction causes the material to actively and quickly warm up to body temperature after the working time, substantially accelerating the intra-oral setting.1 The usual working time is not affected so the impression process will be stress-free for you.
These images, taken with a thermographic camera, demonstrate Imprint 4’s unique active self-warming: among competing products, only Imprint 4 material reveals a significant temperature rise to body temperature.

Super-hydrophilicity for highly precise impressions

A unique feature of Imprint™ 4 VPS Impression Material is its extremely hydrophilic behaviour – even in the unset state. With its optimal flow, the A-silicone captures even the finest details.3 A simple test demonstrates this feature: If you put a water droplet on the interface of two unset impression materials, it will flow to the material with the higher hydrophilicity – i.e. with the higher affinity for water or another aqueous solution.
In a direct comparison with competing A-silicone impression materials, the water droplet always flows to the more hydrophilic Imprint 4 material (shown right).


 
 

Indications

Imprint™ 4 VPS Impression Material is especially designed for all kinds of precision impressions using the 1-step and 2-step impression techniques:

  • crown and bridge
  • inlay and onlay
  • implant
  • orthodontic impressions
 

Technical Data

Imprint 4 materials are available in two setting regimes: The “Super Quick” setting materials are the ideal solution for impressions for smaller cases.
The “Regular” setting versions offer longer working times and are therfore suited for larger cases.

Studies and science

Accelerated setting and self-warming

Enlarge Accelerated setting and self-warming

Progression of setting reaction characterized by increase in Shore hardness measured in different quick setting heavy bodies. Intra-oral setting times are shorter than those measured at room temperature (23°C/73.4 °F). Materials tested: Imprint™ 4 Super Quick Heavy (3M ESPE),Aquasil Ultra Heavy Fast Set (Dentsply), Flexitime® Heavy Body (Heraeus Kulzer), Affinis® heavy body fast (Coltene). Source: J.C. Farr, H. Hoffmann, A. Maurer, P. Osswald, E. Wanek, Shore Hardness Increase of Tray Materials during Setting, CED IADR 2012, #674

Imprint 4 material’s active self-warming leads to a steep increase in Shore hardness which can be equated with accelerated setting. The graph demonstrates that Imprint 4 shows the fastest setting compared to competing VPS materials, making the short intra-oral setting time possible.

Maximum temperature increase of different VPS impression materials, Measurements were taken at room temperature: maximum temperature is lower than in the mouth.
Source: S. Bhatt, J. Bair, R. Perry, G. Kugel, Shore Hardness and Temperature of VPS Materials During Setting, submitted for publication at IADR 2013

Imprint™ 4’s active self-warming is responsible for the accelerated setting reaction in the mouth resulting in a short intra-oral setting time. Inside the mouth, the material warms up to body temperature (37 °C / 98.6 °F) which also increases patient comfort during impression taking. Only Imprint 4 VPS impression material displays a significant temperature increase, compared to competitive VPS materials.

 
 

Super-hydrophilicity

Enlarge Super-hydrophilicity

Contact angles after 2 sec. on unset impression material for Imprint™ 4 Light and competitive VPS impression materials in the same setting version and with comparable viscosity.
Source: N. Shakourian, M. Neglia, D. Nobrega, G. Kugel, R. Perry, Comparing Hydrophilicity of VPS Materials in the Unset Stage; AADR 2012, #1024

The method most often used to determine the hydrophilicity of an impression material is the contact angle measurement. In this test, a water droplet is placed on the surface of a specimen and then the spread of the water droplet across the surface is observed and the contact angle is measured. The lower the contact angle, the better the wettability and the higher the hydrophilicity of the impression material.
The table shows the contact angle values 2 seconds after placing the water droplet on unset Imprint 4 Light material and competitive VPS impression materials with comparable setting times and viscosities (Shakourian et al., AADR 2012, #1024). The water droplets were placed 20 seconds after start of mixing. Imprint 4 material shows the lowest contact angle and therefore the highest hydrophilicity.

Recommendation Rate for Imprint™ 4 VPS Impression Material
Source: Field evaluation in Europe and the U.S. conducted by 3M ESPE and Key Group Research.

In an in-office evaluation, more than 3000 impressions were taken with Imprint™ 4 VPS Impression Material. 300 dentists from four countries – Germany, France, Italy, and the U.S. – participated in the evaluation. The dentists’ feedback confirms the very high clinical acceptance.
The short intra-oral setting time, combined with adequate working time, was mentioned as one of the most significant application benefits. Impression accuracy including high detail reproduction was another reason for dentists’ overall satisfaction with Imprint 4. Imprint 4 material delivers extremely detailed and precise impressions thanks to its super-hydrophilicity, and thus allows for reliable and high-quality impression taking even under challenging moist conditions.
