Injectable Flowable Resin-based Composite Veneers Prior to Ceramic Veneers

This case report describes the clinical protocols for using injectable flowable resin-based composite veneers without tooth reduction as long-term prototype restorations, followed by conservative feldspathic veneer restorations.

The patient's primary concern was to improve her smile. After clinical evaluation, injectable flowable resin composite veneers were recommended as long-term prototypes followed by conservative tooth preparation and ceramic veneers. Flowable composite veneers were created with a transparent silicone index fabricated from a diagnostic wax-up approved by the patient. No tooth reduction was required to place this type of composite veneer. Later, a printed reduction guide was used to provide conservative tooth preparation followed by the cementation of thin feldspathic porcelain veneers under full isolation with a rubber dam.

Injectable flowable resin-based composite veneers can successfully act as long-term esthetic prototypes before ceramic veneers. The outcome of these restorations is very predictable because the diagnostic wax-up anatomy is transferred to the mouth through the transparent silicone index, and they can be placed without tooth reduction. Conservative tooth preparation can be performed on the composite veneers so that minimal tooth structure is removed to maximize the bonding performance of ceramic veneers.
