The biggest challange with most large antierior composite restorations is achieving an invisible margin between the restorative material. The factors that influence esthetic success include:

  • The amount of natural tooth structure loss
  • The ability of the restorative material to mimic the remaining tooth structure
  • The restoration's polish over time
  • The amount of staining that exists as part of the patient's lifestyle

With specific techniques, every clinician can improve the esthetic outcomes of their anterior composite restorations.

In this case, the patient had esthetic concerns regarding the discolored filling on his tooth #9. While the patient had other evidence of occlusal dysfunction, the patient's primary concern was an improved esthetic outcome, and that became the primary goal of the restorative therapy.

In order to make the margins of the restoration blend with the natural tooth structure, it is suggested to smooth out the rough, fractured enamel prisms with a long, wavy bevel; etch and bond beyond the bevel; place the dentin composite beyond the dentin/enamel margin; and use an oxygen-inhibited gel for the final curing. These simple techniques created an improved esthetic outcome ad a satisfied and smiling patient.
