Formulating a Better Composite

In the years since their introduction, resin-based composites have replaced dental amalgam as the most placed restorative material in developed countries. This marked rise in popularity can be attributed to the attractive, tooth-like esthetics that composites offer coupled with increased concerns for mercury content in amalgam.

Historically, composite restorations were considered functionally inferior to amalgam. With diminished longevity as well as challenging and time-consuming placements, particularly for class II procedures, resins were a costly and questionable option for both patients and practices. Over time, however, technological advances have allowed composite restorations to compete with and even surpass their amalgam counterparts. Currently in their 10th year of production, Kulzer’s Venus Diamond® composite has been lauded among the best of the modern generation of composite materials.[1] Delivering exceptional esthetics, quality and performance, the Venus family of nano-hybrid universal composites are designed to exceed the rigorous expectations of today’s dentists and patients.

The Venus line of composites includes Venus Diamond, Venus Pearl and Venus Diamond Flow—three viscosities all formulated with one proven chemistry. Composites traditionally contain one of several polymerizable monomers, the most common being Bis-GMA. Unfortunately, the use of Bis-GMA combined with reactive thinners often leads to restorative failure due to higher shrinkage and higher shrinkage stress. These issues can, in turn, produce fractures and secondary caries. Kulzer scientists combat this phenomenon by replacing Bis-GMA with Tricyclodecane (TCD), an innovative alternative that results in longer-lasting, more effective restorations.

Venus composites’ patented TCD-urethane monomer matrix is complemented by a newly-developed nano-hybrid filler system as well as improvements to the initiator system and stabilizers. Together, these components form a composite with superior physical properties including minimal shrinkage and shrinkage stress along with high flexural strength and wear resistance. In addition to their impressive physical properties, Venus composites have received high praise for their outstanding, chameleon-like esthetics and excellent consistency, handling and polishability.[2] Available in three viscosities and a spectrum of shades, Venus composites are suited for all clinical indications and patient demands.
