Elastomeric Impression Materials

Description

What are Elastomeric Impression Materials?

Elastomeric impression materials are a type of dental material used to create precise and flexible molds of teeth and oral tissues. These materials are known for their ability to accurately capture fine details and provide a flexible, yet stable, impression.

Types of Elastomeric Impression Materials

Polyvinyl Siloxane/ Addition Silicone Impression Materials: Vinyl polysiloxane (PVS) or addition silicone impression material impresses in detail reproduction, making it ideal for precise crown, bridge, and implant models. Its various viscosities bond well, allowing for accurate impressions with less viscous materials supported by thicker ones. PVS maintains dimensional stability once set, ensuring accuracy during packaging and transport.

However, PVS is sensitive to chemical contamination from latex and retraction cords, which can lead to inaccuracies. It can also tear easily due to its tendency to lock into interproximal spaces and its short working time, making it less suitable for full-arch impressions or partial dentures.

Advantages:

• Pleasant odour
• Short setting time
• Accurate recording of fine details

Disadvantages:

• Hydrophobic, requiring teeth and gums to be dry
• Putty material is stiff and challenging to handle
• Poor flow into moist sulcus
• Low tear strength
• High cost

Polyether: This is used for precise impressions, particularly for crown preparations, due to its high accuracy. It comes in a base paste and an accelerator paste, which are mixed to initiate polymerization.

Advantages:

• Highly dimensionally stable
• Excellent accuracy
• Short setting time

Disadvantages:

• Short working time
• Stiff and prone to tearing
• Water absorption
• Requires blocking out undercuts
• Most expensive among impression materials

Condensation Silicone: Condensation silicone impression material was developed to address the limitations of polysulfide. It is used for precise impressions, such as those required for crown preparations. It consists of a base paste and a low-viscosity liquid catalyst, which are mixed to initiate polymerization.

Advantages:

• Pleasant odour
• Optimal working time
• Accurate detail recording

Disadvantages:

• Hydrophobic, requiring drying of gums and teeth before use
• Casts must be poured immediately after taking impressions
• High polymerization shrinkage

Applications of Elastomeric Materials:

Elastomeric impression materials, including polyvinyl siloxane (PVS) and polysulfide, are designed to stretch or compress slightly and then rebound to their original shape once the impression tray is removed. This flexibility allows them to accurately reproduce both hard and soft structures of the mouth, including undercuts and interproximal spaces. The degree of rebound directly impacts the accuracy of the impression.

Inelastic materials such as zinc oxide-eugenol (ZOE) paste and plaster are more suitable for making impressions of edentulous jaws or soft tissues. These materials do not compress the tissue during tray seating, making them ideal for such applications. Impression compound is frequently used to create trays for full denture construction.

Advantages of Using Elastomeric Impression Materials:

Elastomeric materials like PVS and polysulfide capture fine details with high accuracy and maintain shape over time. Their hydrophobic nature reduces distortion from moisture, and they come in various consistencies for versatile use. They generally have a pleasant odour, are easy to handle, and exhibit minimal shrinkage during setting, ensuring reliable impressions.

FAQ’s:

Q1. What is an elastomeric material?

Ans. Elastomeric materials are flexible and rubber-like substances used in dental impressions. They can be stretched or compressed and then return to their original shape, providing accurate reproductions of oral structures.

Q2. What is the classification of elastomeric materials?

Ans. Elastomeric materials are classified into several types based on their chemical composition and properties:

Polyvinyl Siloxane (PVS) / Addition Silicones

Polysulfide

Condensation Silicones

Hydrocolloids

Q3. What is inelastic impression material?

Ans. Inelastic impression materials are rigid substances that do not deform significantly after setting. They are typically used for making impressions of edentulous (toothless) jaw structures and soft tissues, as they do not compress the tissue during tray seating. Examples include zinc oxide-eugenol (ZOE) paste and impression plaster.

Q4. What is putty impression material?

Ans. Putty impression material is a type of high-viscosity elastomeric material used in dental impressions. It is thick and dense, providing a firm and stable base that captures detailed impressions of the teeth and oral structures. Often used in combination with lighter-bodied materials, putty is ideal for creating accurate molds, especially for crown and bridge work.

Q5. What are the four types of elastomeric materials?

Ans. The four types of elastomeric materials are:

Polyvinyl Siloxane (PVS)/Addition Silicone

Polyether

Condensation Silicone

Polysulfide

Q6. Which elastomeric impression material is most accurate?

Ans. Polyvinyl Siloxane (PVS), or addition silicone, is considered the most accurate elastomeric impression material. It offers excellent dimensional stability, minimal shrinkage, and high precision in reproducing fine details.

Q7. What are the advantages of elastomeric?

Ans. Elastomeric dental impression materials provide high accuracy and dimensional stability, capturing fine details and maintaining their shape over time. Their elasticity allows for easy removal from the mouth, while their hydrophobic properties resist moisture.
