Bis-acryl resin are gaining the preference of dental surgeons for the production of temporary restorations and mockups, and are therefore increasingly used in dental clinics. But, ultimately, what are the advantages of working with this type of resin? Here we list the five main ones:
Esthetics
There is no doubt that aesthetics are a major differential factor for bis-acryl resins, especially when compared to acrylic resins.
Very similar to the aesthetic characteristics of composite resins, bisacrylic resins present naturalness, high gloss and polish, color stability (except when subjected to a diet rich in colorants) and shade options compatible with the Vita scale and whitened teeth.

Easy handling
The double-body automixers for bis-acryl resins make it possible to homogenize the phases in the exact proportion, facilitate application and optimize the professional’s working time.
PrimmaArt by FGM, for example, is available in cartridge versions, for use with a universal gun, and syringe versions, a compact option.
Both versions come with economical tips, which make the automixing with up to 40% less material waste compared to conventional tips.
Dam time
Provisionals and mockups made with bis-acryl resins have a low setting time, like PrimmaArt, which takes no more than 2 minutes to complete self-polymerization.
Low heat release
Another clinically relevant aspect is the low heat release during polymerization when compared to acrylic resins, thus reducing the possibility of causing sensitivity in vital teeth and providing more comfort to the patient.
Even compared to other bis-acryl resins, PrimmaArt by FGM presents better indices, as shown in the graph above: the lower the energy released by the polymerization reaction, the lower the amount of heat produced.
Strength and durability
High surface hardness, low polymerization shrinkage and abrasion resistance are factors that contribute to increasing the strength and durability of mockups and provisionals made of bis-acryl resin, making it suitable for short and long-term procedures.
