Resin composite application
tooth
Using a hand instrument (CompoRoller™, Kerr, Switzerland), the resin composite increments were carefully inserted between the matrix strip and the tooth. The matrix was then gently closed facially with slight incisal direction starting from the gingival aspect to ensure proper adaptation of the resin composite at the gingival area and to prevent gingival overhanging, Regular paste resin composite (Universal Nano-Hybrid resin composite Grandio Voco) was applied and light-cured. The restorations were gradually built up by layering composite under the strip to achieve the final shape and contour. The symmetric tooth was created similarly after the final contour of the proximal surfaces was produced.
