Dental Impression Materials: A-Silicones, Alginates, C-Silicones

Addition Silicone impression material

Light Body Impression Materials are also known as hydrophilic vinyl polysiloxane impression materials. They are mainly used for the fabrication of crowns and bridges, denture impressions, and precise detailing of duplication of models. AvueGum Putty/Light Body is an impression material which gives detailed accuracy & excellent margins which the most important requirement of any restoration or prosthesis. 

Clinically, Improved hydrophilicity of AvueGum

Results in better wettability of the tooth surfaces, and performance in a moist environment offer better-than-ever precision.

Hydrophilicity, or contact angle, is most important when the material is being dispensed intraorally. AvueGum low contact angle along with tooth surface helps ensure an accurate impression in the presence of Saliva/GCF

High tear strength of AvueGum

Help to reduce the risk that the impression material tears off upon mouth removal. Another essential aspect for clinical success: The impression material has to withstand all the forces it is exposed to upon removal from the mouth. AvueGum impressions are rigid enough to withstand all the compression forces

Impressions of AvueGum are Dimensionally stable

 Distortions can be the reason for poorly fitting resorations. They usually are not known until the final restoration is ready for seating.AvueGum is dimensionally stable showing a minimum amount of shrinkage 

AvueGum Light body/Medium body shows thixotropic characteristics

Rheological characteristics making single step/putty wash impression more accurate. As AvueGum material shows shear thinning while applying pressure making it stable at first and flowable under pressure which is very important for a medium body

The impression is stable and can be cast even after one month 

AvueGum impression can be poured multiple times without jeopardising the accuracy accuracy of  impression material

AvueGum Putty Impression Material has high filler loading.

It is often combined with a AvueGum Light body during the impression procedure, known as the putty-wash technique, and is commonly used for dental impressions.

Impression techniques for Putty/Lightbody

Two techniques—one-stage or two-stage procedures—can be used when taking impressions with AvueGum light body and putty. For one-stage procedures, the wash material is syringed on the prepared tooth, and then the unset putty is seated over the light body material. AvueGum Putty Impression Material is very soft making it possible to capture margins in wash material as it is not pushed by its very heavy body consistency

For two-stage procedures, the initial putty impression is made and allowed to set, and then it is subsequently relined with wash materials,As per certain studies, two step impressions are better as all the details are captured in light body

Features of AvueGum Putty/Light body

• A firmly fixed material to allow tray support, yet flexible enough for easy removal.
• Easily mixed to Homogenous & Bubble free consistency Optimized flow guarantees precise detail reproduction in every clinical condition.
• Stays where you want and flows on your demand.
• Thixotrophic – non slumpy. Stable as well as flowable.
• Excellent recovery after deformation from undercuts.
• Can be poured long after taking impression without loss of accuracy.
• High tear resistance

The light body has the lowest viscosity and is placed on hard and soft tissues to record accurate surface details of tooth preparations even in presence of moisture because of its Superior Hydrophilicity.

Medium Body Addition Silicone Impression Material for single step impression.

Avuegum Monophase: Hydrophilic vinyl polysiloxane impression material used as one step impression material for implant impressions, edentulous, Crown & bridge  impressions.

AvueGum Mono acts both as tray material & wash impression material

The flow or viscosity of an impression material is dependent on the filler content. There are four basic categories: low (syringe or wash material), medium (one-step monophasic material), high (tray material), and very high (putty material)

AvueGum Mono has Excellent flow properties

AvueGum Medium body captures fine details for precise impressions it is stable as tray material and once prssure is applied will turned in low viscisity material.

Better initial hydrophilicity among all viscosities

It allows for accurate, void-free impressions even in moist conditions.AvueGum low contact angle along with tooth surface helps ensure an accurate impression in the presence of Saliva/GCF

Excellent hydrophilicity and outstanding thixotropy during processing and high final hardness after setting, the medium-viscosity material satisfies the requirements for perfect monophase impressions.

Helps get an accurate impression in a single step

This helps in reducing the need for costly adjustments, remakes and retakes.

Avuegum Monophase Impression material improves both, wettability on the tooth surface and model detail reproduction.

AvueGum Light body/Medium body shows thixotropic characteristics

Rheological characteristics making single step/putty wash impression more accurate. As AvueGum material shows shear thinning while applying pressure making it stable at first and flowable under pressure which is very important for a medium body impression material

The ability to record the tooth preparation accurately during the impression stage is critical for producing well-fitting crowns and bridges.

Shows Shear thinning characteristics

Viscosity is important when subgingival margins are to be captured. The ability of the impression material to reach the base of the sulcus is not only dependent on the viscosity but also the width of the sulcus. A wide sulcus allows for greater flow and thickness, which increases tear strength. Whichever method of sulcus preparation (mechanical, chemical, or surgical) is employed, it is critical that sufficient space is provided.Its shear thining property helps to incease its flow

Impression exhibits good dimensional stability

Stability and accuracy are necessary to record the fine details of hard and tissues and obtain biologically, mechanically, functionally, and esthetically acceptable restorations.

Addition polyvinyl siloxane impression materials have four types of viscosity to suit different needs.The medium body is commonly used as a monophase material or single-viscosity technique during crown and bridge work or for dentures.

Features

• Thixotropic characterstics and high tear strength.
• Uncompromised physical properties to capture accurate impressions.
• Excellent  surface detail reproduction.
• Dimensionally stable VPS chemistry to have distortion-free impression.
• Decrease in Viscosity with Increasing Shear-thinning
• Exceptional Hydrophilicity for its superb performance in the presence of moisture

Interactions

• Avoid contact between the impression material and latex gloves, Skin secretion because these inhibit the setting process.
• Avoid contact with retraction solutions, as residues of retraction solutions can delay the setting time.
• Do not mix Avuegum MONO with condensation silicone or polyether impression materials.

Honigum - Putty: Hand-mix precision VPS in putty consistency

Snap-Set technology

Thanks to the DMG-developed Snap-Set technology the new Honigum-Putty offers a so far unrivaled combination of comfortable working time and short time in mouth. Its generous working time reduces the »mix stress« to a minimum.

Deformations due to already set material are prevented, and micro movements are reduced by the quicker cross linking (see »Snap-Set« in graphic). For the patient the shorter time in mouth translates into significantly more comfort during the treatment
