The TPH Spectra ST composite portfolio covers the full range of dentist's handling preferences and esthetic needs. And thanks to SphereTEC filler technology, the entire portfolio offers optimized performance in the areas that matter most, helping clinicians achieve reliable, esthetic results efficiently.
Discover how SphereTEC filler technology overcomes limitations in composite design by optimizing submicron particles to deliver unique features and ideal results.
Universal CLOUD shades for common cases
SphereTEC’s primary filler particles and resin together enable an excellent chameleon effect for simplified shade matching. One universal CLOUD shade is all you need for the majority of cases.
Plus dentin and enamel shades for complex anterior cases
For esthetically demanding anterior cases, TPH Spectra ST Effects and TPH Spectra ST universal CLOUD shades work together in a simplified layering technique.
TPH Spectra ST is a Universal Composite Restorative indicated for direct or indirect replacement of missing or deficient tooth structure in primary and permanent anterior and posterior teeth.
SphereTEC is the new proprietary filler technology used in TPH Spectra ST. The SphereTEC filler particle manufacturing process uses submicron glass and spray-granulation to produce well-defined, pre-polymerized spherical filler particles. The SphereTEC fillers’ morphology, particle size distribution and surface microstructure are the key for the excellent handling, strength, and polishing characteristics of TPH Spectra ST.
Yes, all 6 TPH Spectra ST shades are available in low-viscosity (LV) and high-viscosity (HV), and in both Compules tips and syringe delivery.
TPH Spectra ST was designed to provide simplified shading. Thanks to an enhanced chameleon blending effect, full coverage of the 16 VITA® classical shade system (A1-D4) can be covered with just five TPH Spectra ST shades of moderate translucency. In addition, a bleach white (BW) shade is available.
The distinct chameleon effect of TPH Spectra ST enables each TPH Spectra ST shade to match several VITA® shades.
There are 3 effects responsible for the distinct chameleon effect of TPH Spectra ST:
The combination of these 3 effects enables 5 TPH Spectra ST shades to match the whole VITA® range.
TPH Spectra ST is chemically compatible with conventional (meth)acrylate-based dentin/enamel adhesives including Dentsply Sirona adhesives designed for use with visible light cured composite restoratives, like Prime&Bond elect universal adhesive.
The stain resistance of light curable resin composites is determined by both the nature of the resin and the nature of fillers. TPH Spectra ST composite’s excellent stain resistance is due to its highly hydrophobic resin matrix and low porosity fillers that prevent colorants’ penetration.
