Given the large number of direct restorations placed by dentists, selecting the right universal composite is not only very important but also equally daunting. Recently, Dentsply Sirona introduced TPH Spectra ST universal composite restorative to provide improved benefits for clinicians such as handling, enhanced chameleon blending effects, and improved wear and polishability for lasting durability.
The key improvements in TPH Spectra ST composite are made possible by SphereTEC filler technology, Dentsply Sirona's proprietary method of manufacturing microscaled, well-defined spherical superstructures comprised of submicron glass. The SphereTEC fillers are spherical pre-polymerized fillers with a mean size of 15 μm obtained via a spray-granulation process. The spherical form leads to a ball-bearing-like effect, which results in both high slump resistance and improved sculptability and adaptation to the cavity form. Via a capillary effect, the fillers' microstructure can bind more free resin than usual fillers. This lack of free resin at the material surface gives the TPH Spectra ST a matte-finish during placement and virtually eliminates stickiness to hand instruments.
TPH Spectra ST is indicated for both anterior and posterior restorations. As with its predecessor TPH Spectra, two viscosities, low and high, are available. The low viscosity version contains a slightly lower filler load to reduce the viscosity without affecting its physical properties.
To help achieve a shade match that can make restorations indistinguishable to surrounding tooth structure, the composite features improved chameleon blending effects. This provides several benefits to the clinician and dental office. First, in difficult shade environments using a composite that blends easily can make shade matching easier even when using only a single shade. Next, because fewer shades are needed, money and shelf space can be saved with reduced inventory. To accomplish this, TPH Spectra ST is offered in five Cloud shades to match the full Vita range. Cloud shading involves grouping similar shades together (e.g., A1, B1, C1) and designing a single resin composite with a matched refractive index that can blend and mimic surrounding color. For example, Vita shade A1, B1 and C1 teeth can be restored with a single shade of TPH Spectra ST A1. Lastly, once the material has been placed, TPH Spectra ST provides easier and faster finishing and polishing when using the Enhance system.
