Dental Silicone Impression Materials: Technical Buying Guide
In the world of restorative dentistry, where extreme precision is paramount, choosing the right dental impression material is the first step to success. Among various impression materials, VPS (Very Polystyrene Silicone), commonly known as dental silicone impression material, is highly regarded for its exceptional performance. It is not only the industry standard for high-precision impressions, but also a solid foundation for ensuring a perfect fit for restorations.
This article, a manufacturer’s expert guide, provides an in-depth understanding of the chemical properties and types of dental silicone impression materials, as well as how to choose the right one based on your technical needs.
Core advantages of silicone impression materials: Why is it the industry’s first choice?
The exceptional performance of silicone impression materials comes from their distinctive chemical mechanism — addition polymerization. This process produces virtually no by-products, resulting in unmatched material stability.
- Outstanding Dimensional Stability: This is the core advantage of VPS (Vinyl Polysiloxane) materials. Unlike traditional alginate or condensation-cured silicones, VPS impressions exhibit negligible shrinkage after setting. This means the impression can be stored for a period of time before pouring or transport without losing accuracy, effectively avoiding costly remakes due to model distortion.
- High Precision and Fine Detail Reproduction: VPS materials offer excellent hydrophilicity and flowability, allowing them to easily adapt into minute crevices between teeth and gingiva, capturing precise marginal details. This is critical for fabricating all-ceramic crowns and veneers that require perfect marginal fit.
- Superior Elastic Recovery: When removed from undercut teeth or prepared abutments, VPS materials quickly return to their original shape and resist tearing. This ensures the integrity of the impression and significantly increases procedural success rates.
Understanding the Different Types: Heavy Body, Light Body & Bite Registration Materials
To meet diverse clinical needs, silicone impression materials are designed with different viscosities.
Heavy Body: High-viscosity material primarily used to fill the impression tray, providing sufficient rigidity and pressure to ensure the overall form of the impression.
Light Body: Low-viscosity material with excellent flowability, typically injected into the gingival sulcus and around the prepared tooth to capture the finest anatomical details.
Bite Registration Materials: Specifically formulated to record the occlusal relationship between upper and lower teeth. They set quickly and have high hardness, ensuring accurate transfer of bite information.
The right impression technique, such as the dual impression method, combines heavy body and light body materials to achieve both macro form and micro detail accuracy in the final impression.
