14 I I clinical_ partial-coverage restorations The small chip in the incisal edge of #8 was then etched with 37 percent phosphoric acid for 30 sec- onds, rinsed and gently dried, scrubbed with Adhese Universalfor20seconds,driedandlightcuredfor10 seconds, followed by the placement of Tetric EvoCe- ram composite (Ivoclar Vivadent), which was light cured for 20 seconds. Occlusion was verified and the restoration was polished with Astropol polishers (Ivoclar Vivadent). The patient was seen for a two-week post-operative visit. He reported no issues with his treatment and was very pleased with his final result (Fig. 11). _Conclusion This case illustrates the potential for modern adhesive dentistry and digital workflows to improve outcomes for patients. Partial-coverage ceramics maximized the preservation of natural tooth struc- ture while still meeting the patient’s esthetic expec- tations, providing him with the most conservative treatment possible and giving the involved teeth the best long-term prognosis for success. Digital impressioning and restoration design combinedwithchairsideCAD/CAMallowedforthese restorations to be performed immediately in a single visit. This greatly streamlined the workflow process and,atthesametime,significantlyenhancedpatient satisfaction._ _References 1.
