Esthetic crown lengthening followed by ceramic veneers can be performed for a patient with a gummy smile and defective teeth. However, definitive ceramic veneer restorations can be achieved after 3–6 months of surgery. During the healing period, provisional splint veneers for esthetic prototypes with conventional technique may create uncleanable interproximal areas, which leads to inflammation and interference with the healing process. This case report demonstrates a workflow of an injection layering technique for a patient with a gummy smile and discolored and worn teeth. At the early stage of esthetic crown lengthening, flowable composite resins are injected into transparent silicone index fabricated from a diagnostic wax-up, including cut-back and internal stain to mimic the internal characterization of the incisal edge of natural tooth color to create a long-term provisional nonprep veneer. The use of this technique with a simple and predictable workflow allows patient for function and evaluates phonetics, lip support as well as a highly esthetic outcome.
