Impression silicones: addition and condensation types compared

30 August 2022

There are a many different impression materials on the market. Some of these, like hydrocolloids, are intended only for preliminary impressions while others, like elastomers, offer better performance and can therefore be used for final, precision impressions. Elastomers are also used to make other materials in addition to impression silicones. Impression silicones come in two types: […]

Abrasion and erosion are the two most frequent causes of loss of dental tissue. Abrasion is a mechanical phenomenon caused by repeated abrasive movements, which may be either parafunctional, like bruxism, or traumatic, such as incorrect brushing techniques and, possibly, the use of highly abrasive toothpastes. Erosion, on the other hand is a phenomenon of […]

The advantages of scanning a dental impression
