In view of successful aesthetic dentistry, the outcome of restorations depends heavily upon the understanding of, and adherence to, the principles involved in its production and application. Success can only be assured if the dentist follows a defined protocol with each patient to ensure that all factors, such as smile design, margin placement, material and shade selection, and communication between the patient, dentist, and lab, are rigorously controlled. Only when all of these factors are thoroughly considered, utilizing current evidence, can dentists have predictable results and happy smiling faces.
