Placement of the restorations In preparation for the ad- hesive cementation of the resto- rations, the temporaries were removed and the teeth cleaned. The anterior restorations were checked in the mouth using a try-in paste and the aesthetic re- sults were subsequently assessed. The occlusion was checked in de- tail. Next, the ceramic restorations were etched with 5% hydrofluoric acid for 20 seconds. They were cleaned in an ultrasound bath and dried. Their contact surfaces were silanised (Monobond Plus, Ivoclar Vivadent). Thereafter, a bonding agent (Heliobond, Ivoclar Vivadent) was applied. The individual ce- ramic components were tem- porarily stored in a container to protect them against light and contamination. The teeth were then conditioned. A rubber dam was placed and the teeth were carefully air-abraded with alu- minium oxide (0.5 µ). Subse- quently, a 37 % phosphoric acid gel was applied and thoroughly rinsed off after a reaction time of 15 to 20 seconds. The preparations were dried to the extent that a slightly moist, shimmering den- tine surface was visible. The ap- plication of the bonding agent (Syntac, Ivoclar Vivadent) followed. The restorations were placed with the light-curing luting composite VariolinkVeneer(IvoclarVivadent). First, the veneers of the two cen- tral incisors were seated and their fit checked. Then one restoration after the other was placed on both sides. Before the restorations were light-cured for the last time, the margins were coated with glycer- ine gel to prevent the formation of an oxygen inhibition layer. We removed the excess with a fine diamond paste and polishers and then we polished and smoothed the margins. After the final exam- ination, we checked the aesthetic and functional parameters in par- ticular (Figs. 11 & 12). We provided the patient with a protective bite guard and then released her from the practice. Result The all-ceramic restorations looked completely natural in the patient’s face and her facial ex- pression had completely changed. The young woman appeared to be relaxed and enjoying her new smile (Fig. 13). The first recall ex- amination took place three days after the restorations had been placed. At that stage, the condition of the soft tissue was excellent. It had fully adapted to the ce- ramic surfaces (Figs. 14 & 15). The success of the treatment was con- firmed at the six- and 12-month recalls (Fig. 16). Conclusion Sound functional principles, excellent aesthetic design skills and an outstanding materials system combined to fulfil the patient’s ardent wish for a smile makeover. The restorations gave her a new zest for life and im- proved her health at the same time. 16 Dental Tribune Asia Pacific Edition | 1+2/2017 TRENDS & APPLICATIONS Ilias Psarris is a dental technician and runs his own dental laboratory inAthensinGreece.
