Thermoplastic Resin Material for Denture Base (Polycarbonate)
BASIS PC is a new semi-flexible thermoplastic injection resin base material.
BASIS PC is allergic reaction-free, odorless and easy to polish.
It is applicable for both full and partial dentures injection technique.
Features:
- Balanced Strength
Basis PC mediates the gap between Nylon and Acrylicʼs strength characteristics resulting in its exceptional and distinctive quality.

- Outstanding Stain Resistance
Basis PC effectively resists stain similar to that of acrylics.
High ΔE*(Reflectance) and ΔE*(Transmittance) of Nylon indicates ineffective surface stain resistance and penetration of stain into the material, respectively (*The larger the ΔE, the more susceptible material is to stains.)

- Superb Durability
Basis PCʼs hardness is proximate to that level of Nylon.
Lower hardness, compared to acrylics, proves higher tenacity.

- Semi-Flexible
The concurrent proportion of Basis PCʼs strength characteristics gave rise to a new semi-flexible denture base material.

- Exceptional Water Sorption
Highly hydrophobic functionality resists water sorption.
Propagation of bacteria-causing odor is controlled.
Minimal deformation in intra-oral environment for long period of use is guaranteed.
