Clinical procedure Theveneerswereindividuallycementedusing the adhesive technique, starting with the inci- sors (Fig. 5), followed by the lateral incisors and canines and so on, thus allowing the clinician to carry out corrections on the proximal areas of the less prominent teeth (distal surfaces of canines or premolars). The restorations were conventionally placed with Variolink Veneer (Ivoclar Vivadent). In a last step, the composite jointswerecarefullyfinishedwithascalpelinor- der to maintain the surface gloss of the ceramic and the excellent fit in the periodontal tissue (Figs. 6–8). _Conclusion Clear communication between the dentist and the dental technician is mandatory in clin- ical cases such as this to allow as much infor- mation as possible to be exchanged (models, images of the initial situation, images of the preparations and their shade, impression of the temporary restorations in place, shade de- termination). In the present case, the ceramist designed the margins of the contact surfaces on the stone model 2 mm from the papilla because the distance between the contact point and the tip of the papilla had to be less than 5 mm in order to allow the papilla to grow back.2 After some months, the papilla will have grown and filled the small spaces that were reserved for it. This is also a confirmation of the bio-compa- tibility of the lithium-disilicate glass-ceramic IPS e.max Press (Figs. 9 & 10). By strictly observing the treatment strategy and using materials that show optimum opti- cal and biomechanical properties, the patient’s smile was modified and restored in accordance with the principles of minimally invasive den- tistry.
