Custom-Made Composite Shade for Matching an Odd-Shaded Restoration

Abstract

Objective: This case report aims to present how to fabricate a new restoration to match existing odd-shaded ones. Clinical considerations: A polycarbonate provisional crown was used to produce a cement-retained immediate load provisional restoration over an implant of tooth number #9. Using a color correcting light source, it was noticed that existing restorations had very high value with excess gray hue. XL2 of Premise composite shade tab was the closest match found, and the base shade for the custom-made restoration. Once no shade match was found in commercially available shade guides, there was a demand to produce a custom-made shade to address this case. The facial surface of the provisional crown was prepared as a veneer. Utilizing XL2 Premise composite and adding different amounts of gray color modifier, shade matching was fulfilled by mixing the composite and the color modifier. In this case, five attempts were made to achieve color match. The restoration was polished utilizing Soflex Discs. Provisional crown was in function for 12 weeks. Conclusions: By implementation of the principles of color, restorative materials and characterization kits, the new temporary restoration could match the existing ones using the technique described in this case report.
