Unraveling The Wonders Of Dental Impressions: A Journey Into Dental Artistry

teeth

 Impression materials have undergone a transformative experience, presenting us with a lot of advancement as time passes by.

 The least known but extremely useful fillers are elastomers. They are busy doing their job behind the scenes. Among them, the addition and the condensation of silicones are important.

 Thus, grab your masks (not the COVID type) and get prepped to journey in the weird zone of A Silicone Impression Material. Our aims include the process secrets of these elastomers and why they’re core elements of flawless dental arrangements. Strap in, guys, because we’re about to embark on the ride that all the dentists dread – a dental journey like no other.

What are the advantages of using A Silicone Impression Material?

 Accuracy and Precision:

  • Impressions from silicone capture the real shape of the mould with accuracy.
  • These provide exact moulds of the oral tissues.

Durability and Flexibility:

  • The combination of durability and flexibility of silicone materials make them very practical.
  • They tolerate handling and manipulation in conjunction with procedures.

Chemical Stability:

  • Since the impressions are made of silicon, this material also does not react with other substances.
  • This process is ensured to remain unchangeable and trustworthy from start to finish.

Minimal Shrinkage:

  • Silicone impressions offer minimal shrinkage.
  • They retain their original shape and size reliably.

Elastic and Irreversible:

  • These are silicone rubber that is highly elastic but is unextendable and permanent.
  • It ensures the impression remains intact and reliable.

Smooth Flow and Easy Handling:

  • Removable impressions in collaboration with oral tissues appear as silicone moulds that flow smoothly.
  • They offer ease of use during all your procedures.

Compatibility and Peacekeeping:

  • Silicone materials work well with other dental materials.
  • They ensure a hassle-free experience and reliable results.

What are the characteristics of A Silicone Impression Material?

  • Safe: It is safe for gums because it doesn’t cause any harm when it comes into contact with gums and other oral tissues.
  • Fluid: Smoothly reaches every detail before it solidifies.
  • Time-friendly: Provides sufficient period to work interruption-free.
  • Compatible: Compatible with gypsum materials for almost perfect results.
  • Elastic: Stretchy, strong, retaining original size and shape.
  • Clean: Keeps clean even after thorough disinfection.
  • Tasteless: No strange flavours for patients, that makes their experience during procedures so comfortable.
  • Easy and Affordable: Easy to use, affordable for every practice.

An ideal silicone impression material checks off all these boxes and thus provides for efficient and comfortable dental procedures.

What are the types of silicone impression materials? 

There are two types – Condensation and Addition.

1. Condensation silicones

Condensation silicones bear unmatched mechanical qualities that aid in flow during undercuts without giving way to deformation. It is also perceived as an affordable option when compared to more expensive elastomers like Addition silicones. Their versatility is manifested in their ability to match with different dental appliances ranging from fixed to removable prostheses.

Moreover, their hydrophobic nature shields them from the pains of syneresis and imbibition, thus enabling them to remain steadfast dimensions even in the presence of environmental humidity. Nevertheless, they fall into the gap of dimensional consistency because the release of alcohol is created during condensation, and this triggers contraction.

On the other hand, the hydrophobic nature of the enamel can pose problems if the oral environment isn’t clean. The microscopic faults like bubbles and holes, especially near the gingival margin, can arise as a result. Research, in this case, shows high accuracy if the conditions are flawless enough and the casting is done within a short timeframe.

[Main Extract] – Condensation silicones are undisputed leaders in dentistry, being comprehensive in elasticity, affordability, and moldability. Whilst hydrophobic properties of these polymers serve to prevent dimensional distortions, warnings against their adhesive limitations and imperfections under less-than-perfect conditions are to be made.

2.  Addition silicones

Addition silicones, often called polyvinylsiloxanes, hit the market in early 1980, thus attaining the zenith of materials for dental impressions. In contrast to addition silicones, which trigger polymer vulcanization just by the application of a catalyst, condensation silicones need to go through the process of polycondensation by heating. The cross-linking dance happens between the polymer’s vinyl groups and the “activated” silane groups through the platinum salt catalyst, like chloroplatinic acid.

While cramming reactions generate waste products, additive silicones stand proud, having no waste. This leads to the fact that reinforcement polysulphides and silicones, having syneresis reaction by-products, are much more dimensionally stable than condensation polysulphides. The silicone impression captured with the Addition Silicones follows the format of the silicones taken under the condensation system.

[Main Extract] – The addition of high-performing silicones, known as polyvinylsiloxanes, started in the 1980s. Unlike condensation silicones, which have polycondensation at a higher temperature, addition silicones using catalysts are polymerized. They are thermostable and leave no residue at the end of their service life, distinguishing them from condensation polysulfides. Their impression frame mimics vapor silicones by having superior properties.

Exploring the Mixing and Manipulating Techniques of Polyvinylsiloxanes

Modified vinyl silicone blending and tinkering is much less complicated than silicon by condensation, which is a different tale. In the last few years, a new trend in the use of these devices as automatic mixing cartridges and systems has been identified. This facility is designed to eliminate manual mixing action and make the mixture smooth and bubble-free, with tons of labor invested by dental professionals to produce a final product.

These general-purpose polyvinylsiloxanes have strength and reliability as they return to their original shape and maintain their size even after being extended. A striking feature is the fact that the duplex of the polyvinylsiloxanes can be perfectly recreated. Besides, these barriers also demonstrate the property of rheopexy, which makes them more flowable when there is pressure in their environment. When compared to other plaster models of teeth, it is this very quality that allows light, easily removable outcomes to be achieved with the most accuracy possible.
