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

Impression materials play a fundamental role in the precise fabrication of dental prosthetics and restorative procedures. They accurately replicate oral tissue morphology, assisting in the creation of precise dental prostheses. Selecting the right dental impression material is critical for achieving optimal clinical results and ensuring patient satisfaction. There are different types of impression materials, each showcasing its own unique and distinctive characteristics that play a crucial role in various dental procedures and prosthetic fabrication processes.

Types of Impression Materials

Alginate Impression Material

Alginate, a hydrocolloid material, is widely used for preliminary impressions due to its ease of use and cost-effectiveness. It exhibits adequate elasticity and tear strength, making it suitable for capturing general impressions for diagnostic models, temporary restorations, and orthodontic appliances. However, alginate impression material has limitations in terms of dimensional stability and detail reproduction, making it unsuitable for precise prosthetic fabrication. Dental impression putty, another commonly used material in dentistry, offers better dimensional stability and detail reproduction compared to alginate. It is often preferred for more precise impressions required for prosthetic fabrication, such as crowns, bridges, and dentures.

Avue Algin, offered by Dental Avenue India, stands out as a reliable choice for preliminary impressions. With its user-friendly nature and cost-effectiveness, Avue Algin simplifies the impression-taking process while ensuring adequate elasticity and tear strength. It provides dentists with a dependable option for capturing accurate preliminary impressions for a variety of dental applications.

C Silicones (Polyvinyl Siloxanes)

C silicones, commonly known as addition silicones, are preferred for their excellent accuracy, detail reproduction, and dimensional stability. These elastomeric materials offer superior tear resistance, making them ideal for crown and bridge impressions, implant impressions, and removable prosthodontics. Additionally, C silicones feature rapid setting times and low viscosity, facilitating precise impressions with minimal patient discomfort.

Dental Avenue India offers Avue Dentasil, renowned for its accuracy, tear resistance, and rapid setting times. Ideal for crown and bridge impressions, implant impressions, and removable prosthodontics, Dentasil ensures precise impressions with minimal discomfort, making it a top choice for demanding clinical scenarios.

A Silicones (Polyether)

A silicones, or polyethers, are characterised by their hydrophilic nature and exceptional wetting properties. They exhibit high tear strength, dimensional stability, and accuracy, making them suitable for crown and bridge impressions, as well as implant impressions. A silicones are particularly advantageous in moisture-rich environments, ensuring reliable impressions in challenging clinical conditions. However, their prolonged setting times may pose challenges in time-sensitive procedures. 

Dental Avenue India offers a range of dental impression materials to meet diverse clinical needs. DMG Honigum, a polyether with exceptional wetting properties and accuracy, is ideal for crown, bridge, and implant impressions, ensuring precise results. For situations with high moisture levels, Avue Gum Mono provides reliability, maintaining accuracy even in challenging conditions. Additionally, Avue Gum Heavy and Avue Gum Light Body offer versatile options, catering to specific requirements with their varying viscosities. Avue Gum Putty/Light Body combines the benefits of putty consistency for initial impression and light body for detailed reproduction, enhancing precision in prosthetic fabrication. Despite potentially longer setting times, silicone-based impression materials remain essential for achieving the level of accuracy required in modern dentistry.

Bite Registration Material 

Bite registration materials play a crucial role in capturing accurate interocclusal relationships for prosthetic fabrication and occlusal adjustments. These materials should possess sufficient rigidity and stability to accurately record centric and eccentric jaw positions. Vinyl polysiloxanes (VPS) and polyether-based bite registration materials are commonly used due to their excellent dimensional stability and ease of manipulation. They enable precise recording of occlusal contacts and jaw movements, facilitating optimal prosthetic outcomes.

Dental Avenue India provides Avue Bite, a VPS bite registration material, and DMG O-Bite, a polyether-based option, both ensuring accurate interocclusal relationships and optimal prosthetic outcomes.

Trays & Accessories 

In addition to impression materials, selecting appropriate trays and accessories is essential for successful impressions. Trays come in various designs, including stock, custom, and perforated trays, each offering specific advantages depending on the clinical scenario. Disposable trays minimise cross-contamination risks, while custom trays provide superior adaptation and stability. Accessories such as tray adhesive, mixing tips, and syringes enhance the handling and delivery of impression materials, ensuring consistent results.

Selecting appropriate trays and accessories is crucial for successful impressions. Dental Avenue India provides Angelus Impression Trays, offering various designs including stock, custom, and perforated trays. These trays, along with accessories like tray adhesive and mixing tips, ensure consistent results and minimize cross-contamination risks.
