show your work case study Case report A 21-year-old patient presented to the office in need of a cleaning and smile improvement. The lateral incisors were short and required elongation to improve the final aesthetic outcome. She was interested in a painless treatment option that will allow for alignment and whitening in the future. Photography (Shofu Eye Special III) with retraction using OptraGate (Ivoclar Vivadent) and immediate shade taking (Vita Easyshade) resulted in shade 2M1. Caliper use showed #7 and #10 as 6mm wide and #8 and #9 as 8.5mm wide with nice symmetry (Fig. 2). A scan was performed (iTero Element 5D) along with preoperative photography to assess the ability to bond in a minimally invasive manner. The scan shows minimal characterization on the incisal edges of the lateral incisors and light occlusal contacts, allowing for a chairside additive bonding procedure with an enamel bevel (Figs. 3-6). A preoperative alginate impression was taken and filled with die silicone material (Voco), allowing for a four-minute set time (Fig. 7). Creation of the lingual, incisal and facial surfaces of the veneer was achieved by building up small lobes of Voco Admira Fusion X-tra and light-cured with the Voco Celalux 3 curing light (Fig. 8). Tooth preparation was done with a coarse disc (3M) to create a light bevel on the incisal one-third of the tooth.13 The tooth was prepared for bonding with irrigation using a three-second chlorhexidine rinse and biofilm removal with Bioclear Air Abrasion with aluminum trioxide. After this, a selective etch technique was performed, etching the enamel ring for 15 seconds with 40% phosphoric acid etchant (Henry Schein) with a thorough rinsing protocol. After this, Futurabond U primer/adhesive (Voco) was brushed in two coats over 20 seconds on all surfaces, thinned with a gentle stream of air, 16 Fig. 2 Fig. 3 Fig. 4 Fig. 5 Fig. 6 Fig. 7 Fig. 8 APRIL 2021 // dentaltown.com DT0421_Ajmera_ShowYourWork-MM.indd 16 3/18/21 9:10 AMhttp://www.dentaltown.com
