A seven-week Invisalign programme allowed for enough movement in the upper arch while resolving the mild crowding in the lower arch. The final tooth position can be seen in Fig. 1f. Postorthodontic provisional retention was implemented with removal Essix retainers, which were used for home whitening of the upper and lower teeth. A final shade of BL3 was achieved while the lab created a diagnostic wax-up guided by the smile design. A putty matrix was used to transfer the wax-up to a trial smile (Fig 2). Fig. 1d Fig. 2 Fig.1e Before APT Preps Fig. 3 Once the trial smile was approved by both patient and dentist, the acrylic was used as a guide for crown lengthening on the UR2, and then as a preparation guide for the APT technique (Fig. 3). A decision was made between dentist and patient that the areas of recession would be left with a supragingival margin; the patient declined a grafting procedure. The final restorations from UR4 to UL4 were created from pressed E.max and cemented using Variolink Esthetic LC neutral. Finally, definitive Essix retainers were constructed for retention. ■ Fig. 1f Before After dentaltownuk.com \\ FEBRUARY 2018 31http://www.dentaltownuk.com
