Esthetic rehabilitation of anterior teeth with “copy-paste” concept: a case report

Abstract

The aim of this fully digital workflow was to create harmonic smile correction with esthetic veneers applying orthodontic treatment and the “copy-paste” concept. A 29-years-old male patient presented with the main complaints of the teeth angulation and color discrepancies. Our treatment plan was four IPS e.max CAD MT lithium-disilicate ceramic veneers (12,11,21,22). The initial situation was scanned with 3Shape Trios 3 wireless Pod. The next step was the orthodontic treatment planned with Clear Aligner Studio (3Shape). The 2D smile design was planned with TRIOS Smile Design (3shape) after the orthodontic retention phase. The 3D design was made with 3Shape RealView Engine. Digital wax-up was printed with NextDent 5100 and transferred into the patient mouth without preparation. After 24 hours, the patient came back to the dental office where some esthetic corrections were made. This situation was scanned as a pre-preparation scan. Minimal invasive preparation was made through the mock-up, and the precision situational impression was taken digitally with Trios 3. Based on the pre-preparation scan the veneers were planned with TRIOS Design Studio (3shape). The delivery was made in absolute isolation, cemented with Maxcem Elite Clear (Kerr). The aesthetic outcome of the lithium-disilicate veneers was natural-looking and conservative while providing high optical properties. Digital workflow could provide a more predictable outcome compared with the analog way. The dentist can present the expected result for the patient before the preparation phase. With digital workflow, we can achieve the concept of “copy-paste” dentistry by transferring the digital wax-up to the final restoration entirely.
