Esthetic rehabilitation with porcelain crowns using digital planning

Introduction: The desire for a perfect smile has increased substantially over the past few years. After the esthetic dental treatment, patients seem more confident and happy, which results in greater chances of success in job interviews and better personal relationships. Case Report: A male patient, sought dental care, reporting smile esthetics as the main complaint. After clinical and radiographic evaluations, tooth wear was observed on central and lateral incisors due to dental erosion. A photographic protocol was performed for digital planning and then, from the diagnostic wax-up, a mold was made with addition silicone and bis-acrylic resin was used for the mock-up. The minimally invasive preparation was carried out with diamond burs of fine and ultrafine granulations and consisted in the removal of the live angles and retentive areas. The crowns were made in lithium disilicate (LD) glass-ceramic, following the treatment protocol with hydrofluoric acid, phosphoric acid, adhesive, and a cementing agent. The excess was removed and photoactivation was performed for 40 seconds on the buccal, lingual, and incisal surfaces on each tooth and subsequent finishing and polishing. Conclusion: The clinical success of lithium disilicate porcelain crowns depends on the precise clinical protocol, correct indications, and laboratory procedures.
