Shade Evaluation of Monochromatic Versus Polychromatic Layering Techniques Inrestoration of Fractured Incisal Angle

Anterior Teeth

This clincl trial will be conducted to compare theShade Evaluation of Monochromatic versus Polychromatic layering techniques in restoration of Fractured incisal angle

The use of enamel and dentin shades allow us to reproduce anatomical features such as incisal edge translucency, halo effect, other internal colors and pigments such as craze lines, white patches, white horizontal striations . Anterior composites usually have small filler particles to increase smoothness, nanotechnology has enabled recent advances in dental composite restorations. As a result , a different category of composite resins has emerged, known as nanocomposites. However polychromatic layering is considered to be technique sensitive, from detection of details to proper reproduction of such fine details. The presence of discrepancies between the classic shade guides and the actual shade of composite makes that task more difficult. The use of monochromatic layering with only body shade can serve as a substitute for enamel and dentin, since it has an intermediate opacity between enamel and dentin , and can serve as an easier option with less technique sensitivity than polychromatic layering. Filtek universal as claimed by the company manufacturer to have A NaturalMatch which is a term that describes the combination of 3M technologies and features present within 3M™ Filtek™ Universal restorative. it contains nanofillers, pigments and proprietary low-stress monomers which gives Filtek™ Universal Restorative a combination of esthetic and universal opacity which in turn allow shade blending and making the restoration more invisible with surrounding dentition.
