12 exhibitors Greater New York Dental Meeting — Nov. 28, 2017 Predictable and functional esthetics with low shrinkage and reduced stress By Shofu Dental Staff n One of the greatest limitations in the use of resin composites is the material’s shrinkage during polym- erization. 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 struc- ture. The unrelieved stress can weaken the bond between the tooth structure and the restoration. Consequently, marginal leakage, tooth fracture and a restoration’s displacement may occur and further initiate the forma- tion of secondary caries and post- operative sensitivity. On average, the majority of resin composites in the market shrink about 2 to 5 percent. As polymerization shrinkage can- not be completely eliminated, a pleth- ora of techniques and protocols has been developed to conduct the manip- ulation of restorative procedures to minimize the effects of shrinkage and associated shrinkage stress. Introduction of various new com- posite systems with low-shrink chem- istry may also help overcome the problem. A next generation of a bioactive composite indicated for all cavity classes, I—V, Beautifil II LS (Low Shrink) provides general practition- ers with the means to reduce polym- erization shrinkage and shrinkage stress while creating predictable and functional esthetics. Like all restorative materials from Shofu, this novel composite incorporates the proprietary bioac- tive Giomer chemistry, clinically proven in eight- and 13-year recall studies to release and recharge fluo- ride and other beneficial ions and inhibit plaque formation to help establish a stable pH in the oral envi- ronment. Highly filled, 83 wt percent, Beau- tifil II LS demonstrates excellent com- pressive and flexural strength (ca. 370 MPa and 120 MPa, respectively), maintains ideal color stability and polishes in an instant, producing a long-lasting sheen, according to the company. Among the distinguishing features of Beautifil II LS are its low-shrink 5 Functoonal and naturally beautoful restoratoons created woth Beautofil II LS. (Photos/Frank J.

In rigorous international bench tests, this ground-breaking material demonstrated volumet- ric shrinkage of 0.85 percent and polymerization shrinkage stress of 2.72 MPa, the lowest characteristics among all universal composites in the market today. Shofu attributes these outstanding results to a new proprietary monomer and high-density pre-polymerized fillers, which also exhibit tooth-like optical properties and natural esthet- ics. Available in syringes, tips and value kits, in 14 dentin and enamel shades, Beautifil II LS offers the cli- nicians predictable and functional esthetics with greater strength, higher wear resistance and naturally beautiful esthetics, according to the company. Features of Beautifil II LS (Low Shrink) • Lowest volumetric shrinkage (0.85 percent) and shrinkage stress (2.72 MPa). • Greater strength and higher wear resistance. • Tooth-like esthetics with natural fluorescence and chameleon effect. • Polishes in an instant. • Sustained fluoride release/ recharge with bioactive Giomer chemistry. 5 Beautofil II LS (Photo/Provoded by Shofu Dental)
