When it comes to mixing cements, we generally like to use the lightest shade for centrals and warmer shades as we go distally. This mix-to-match method helps to achieve a natural-looking smile. We ultimately decided, with the patient’s input, to use a dual-cure resin cement (examples are Maxcem, Kerr; Multilink, Ivoclar Vivadent; and PermaCem Automix Dual, Foremost) for the zirconium crown on tooth #5; Cosmedent Ludicrous for #8, 9, 24 and 25; Bright for #6, 7, 10, 11 and 12; and Yellow-Red Universal for #23 and 26. A fresh bottle of bonding agent (examples are Optibond Solo Plus, Kerr; Excite, Ivoclar Vivadent; and Adper Single Bond Plus, 3M ESPE) was selected. Using a fresh bottle ensured that the bond would be at its strongest. The teeth were cured from all angles with the FLASHlite Magna (Discus Dental). Because it is a LED, there is little danger of overheating the teeth. Once the restorations were seated, the patient was ecstatic with the results. She simply could not believe how natural her teeth looked. They were even better in shape and shade than she had anticipated (Fig. 12). The once tetracycline-stained smile was the only smile she had ever known. Now, for the first time in her life, she could look in the mirror and smile with confidence knowing she has a beautiful, natural smile. In this case, a cosmetic image was helpful in showing the patient a 2-D photo of how her smile would look. Yet, it was not until she saw her personalised smile design in real life with the Slip-On Smile that she could really feel what her new smile would truly be like. She was pleased with every step of her smile transformation, with her provisionals and ultimately with the results. Although the mix-to-match method is an extra step that requires more chair time, the results justify the means. And for this patient, this meant a beautiful new smile with minimal tooth reduction to achieve the most natural aesthetics. Each step of this process gained more of the patient’s acceptance of the proposed treatment, which determined her appreciation of the results._ _about the authors cosmetic dentistry Dr Lorin Berland,an accredited Fellow of the AACD, is one of the most sought-after speakers and published authors on cosmetic dentistry in America.He has featured in national and regional magazines and major dental journals, and recently on NBC News, Fox News,and ABC’s 20/20.For more information on The Lorin Library Smile Style Guide,the 8-AGD credit DVD, www.denturewearers.com,and The One Appointment Inlay/Onlay Kit and complimentary 8-AGD credit CD/ROM, call +1 214 999 0110 or visit www.dallasdentalspa.com.
