Injectable Flowable Resin-based Composite Veneers Prior to Ceramic Veneers.

OBJECTIVES: 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. CLINICAL CONSIDERATION: 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. CONCLUSIONS: 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.

Ultrathin Partial Ceramic Veneers in the Esthetic Zone with Tooth Whitening: A 5-year Case Report.

OBJECTIVE: This case report describes a minimally invasive approach with tooth whitening and partial ceramic veneers in the esthetic zone with a 5-year follow-up. CLINICAL CONSIDERATIONS: The patient was initially concerned about the tooth color and previous direct resin composite restorations that chipped on the incisal edges of both maxillary central incisors. Tooth whitening and partial veneers for both central incisors were recommended after clinical evaluation. Two sessions of in-office tooth whitening, first with 35% hydrogen peroxide and later with 10% carbamide peroxide from first premolar to first premolar, were provided. Minimal tooth preparation that only removed the fractured composite restorations was performed followed by placement of feldspathic porcelain ultrathin partial ceramic veneers for both central incisors. We emphasize the benefits of minimal tooth preparation paired with partial ceramic veneers and the importance of masking discolored tooth structure with such thin veneers, including potential tooth whitening. CONCLUSIONS: Overall, we demonstrate a well-planned and executed restorative procedure combining tooth whitening and ultrathin partial ceramic veneers to achieve desired results in the esthetic zone that remained successful for five years.
