Beautifil® II LS (Low Shrink)

Abate shrinkage and shrinkage stress

One of the greatest limitations in the use of resin composites is the material’s shrinkage during polymerization. This process, typically associated with dynamic development of elastic modulus, creates a network of stress cells within the resin composite and its interface with the tooth structure. The unrelieved stress can weaken the bond between the tooth structure and the restoration. Consequently, marginal leakage, tooth fracture, and restoration displacement may occur and further initiate the formation of secondary caries and postoperative sensitivity.

The majority of resin composites currently in the market shrink an average of 2% to 5%. As polymerization shrinkage cannot be completely eliminated, a plethora of techniques have been developed to minimize the effects of shrinkage and associated shrinkage stress.

A new generation of bioactive composite that is indicated for all restorations (Class I to Class V), Beautifil® II LS (Low Shrink) provides general practitioners with the means to reduce polymerization shrinkage and shrinkage stress while creating predictable and functional esthetics.

Like all restorative materials from Shofu, this novel composite incorporates the proprietary bioactive Giomer chemistry, clinically proven in 8- and 13-year recall studies to release and recharge fluoride and other beneficial ions and inhibit plaque formation to help establish a stable pH in the oral environment.1,2

Highly filled, 83 wt%, Beautifil II LS demonstrates excellent compressive and flexural strength (ca. 370 MPa and 120 MPa, respectively), maintains ideal color stability, and polishes in an instant, producing a long-lasting sheen.

Among the distinguishing features of Beautifil II LS are its low-shrink attributes. In rigorous international bench tests, this groundbreaking material demonstrated volumetric shrinkage of 0.85% and polymerization shrinkage stress of 2.72 MPa, the lowest characteristics among all universal composites in the market today. These outstanding results are attributable to a new proprietary monomer, ML-01, codeveloped with Mitsui Chemicals, and high-density pre-polymerized fillers, which also exhibit tooth-like optical properties and natural esthetics.

Available in syringes, tips, and value kits, in 14 dentin and enamel shades, Beautifil II LS offers clinicians predictable and functional restorations with greater strength, higher wear resistance, and naturally beautiful esthetics.
