4 Figure 7 resin where necessary. The teeth were reduced approximately 1.3 mm–1.4 mm [6] on the facial, interproximal, and lingual surfaces, and a 2 mm incisal reduction was ensured to pro- vide minimum material thickness. The cast post number 7 was slightly reduced on the facial surface to allow for proper thickness of the aluminum oxide ceramic coping and overlying porcelain [7]. Coarse chamfer bur (number 30006- 144) and ﬁne chamfer bur (number 38006-145 (Brassler, USA)) were utilized to achieve the preparation and create chamfer margins. In order to make a ﬁnal impression, retraction cord number 00 (Ultradent Products Inc.,) was carefully placed in the gingival sulcus exposing 0.5 mm of uncut tooth structure. Final impressions were taken with Reprosil Quixx Putty, Vinyl Polysiloxane Impression Material Type 1, Very High Viscosity, and Reprosil Regular Body Hydrophilic Vinyl Polysiloxane Impression Material Type 1, Medium Viscosity. Provisional crowns were fabricated using Luxatemp (Zenith/DMG Luxatemp Fluorescence). Luxatemp was ﬂowed into an alginate impression of the diagnostic wax-up and seated into the patient’s mouth. After about ninety seconds, the material had partially hardened and was removed from the prepared teeth. The temporary was removed, and margins were ﬁnished with a Flame Shape Bur (number 888EF012 (Brassler, USA)) to avoid overhangs and ensure gingival health. The interproximal areas were easily accessible to the patient for proper oral hygiene. The interim crowns were then temporarily cemented utilizing temporary cement (TempBond). The desired shade (A2), shape, and contour were detailed in the laboratory prescrip- tion, and digital photographs were sent to the laboratory as well. 7. Final Restoration Placement Prior to the patient visit, all the ceramic crowns were ﬁrst tried in on the cast for veriﬁcation that their contours had International Journal of Dentistry followed the diagnostic design. Anesthesia was achieved, temporary crowns were removed and the porcelain restora- tion was tried in. The teeth were cleaned with course pumice and water to remove residual temporary cement and debris. The porcelain crowns were tried in one by one to assure appropriate margins and occlusion and then shown to the patient. Upon patient approval, photographs were taken and preparations for ﬁnal cementation began. The rubber dam was placed on the patient. When the teeth were ready for cementation, the crowns were prepared for cementation [1]. The cement of choice was FujiCEM (GC America), a resin-modiﬁed glass ionomer cement [2]. This cement was chosen as a deﬁnitive luting material due to its stability, lack of thermal expansion, and minimal microleakage [8]. The interior surfaces of each porcelain crown was coated with a thin layer (less than 1 mm) of the cement [9]. The crowns were seated one by one by gently rocking them into place and using ﬁnger pressure. Occlusion and proper seating were conﬁrmed, and pressure was maintained until the luting cement hardened into a gel-like consistency. Excess cement was removed, utilizing a brush (Microbrush International 2 mm) facially and lingually, and ﬂoss was utilized in the interproximal regions. The rubber dam was removed and the occlusion was checked for light centric contact and pro- per contact on lateral excursion. Adjustments were made as necessary and porcelain repolished [10]. A follow-up ap- pointment was scheduled for a week later. Literature states that the average crown can last 7–10 years [11]. 8. Conclusion At the follow-up appointment, the patient was very happy with the esthetic result and appeared to be in great spirits. He was pleasantly surprised by how his smile had been trans- formed (Figure 4) from a worn, aged, dark, and reversed smile, to a bright, symmetrical, natural look (Figures 5 and 6). Following this procedure, his career, which requires him to appear in the public, has taken oﬀ immensely. He used to appear on television and in print, so smiling was a necessary requirement, which he could not fulﬁll before. His aesthetically pleasing new look has increased his conﬁdence, and enhanced his career (Figure 7). He left our oﬃce with his head held high and a big smile on his face. An aesthetic smile instills conﬁdence, can improve interpersonal relationships, and make a person happier overall [12]. Acknowledgment Special thanks go to the patient. References [1] A. B.
