Sinfony is a new 3rd generation light cured, ultra small particle composite from espe, because of its excellent physical properties (elasticity, abrasion resistance, impact strength and optical properties), Sinfony can be successfully used for a full veneering of fixed and removable prosthesis on metal frameworks (crown and bridge, direct bonded bridges, telescopic and conical crowns, attachments and implant work), veneers, long term temporary cases and for the customisation of pre-fabricated acrylic and ceramic artificial teeth.
Sinfony, in 12 months from its introduction at the 1997 IDS, is now the most widely used laboratory composite material in Germany and one of the most popular in Europe. Why? Because it is the only flowable light cured composite material available for the dental technician (Artglass, Targis, Zeta, Soldex, Bellglass, etc. are all putty like in consistency and must always be manipulated). This is why SINFONY is clearly regarded as the most "user friendly" laboratory composite available today.
The main constituent of Sinfony is a special ultra fine strontium - aluminium- borocilicate glass in the sub-micron particle range. In addition it also contains pyrogenic silica, also known as micro-dispersed silicon dioxide.
Sinfony's exceptional properties result from the perfect control of the filler pre-treatment as well as from the highly active monomer system in conjunction with a specifically optimised photo-initiator system. Components developed and patented by Espe have been applied to both the monomers and initiator.
Sinfony also contains a newly developed monomer system which does not contain Bis-GMA or TEGDMA, unlike its competitors. This special monomer system, a mixture of aliphatic and cycloaliphatic monomers, has a low viscosity and a very high reactivity which importantly leads to a resin matrix that develops a very high density of cross linking. It is for this reason that Sinfony exhibits outstanding materiological properties without requiring the content of its competitors.
Due to the strong hydrophobic nature of the new monomer, Sinfony exhibits the lowest water uptake values of any of the competitive composite systems. This is extremely relevant in terms of long-term colour stability.
