42 — issue 1/2015 Aesthetic and Restorative Dentistry Article NATURAL LAYERING CONCEPT — a simple, reliable and effective protocol to achieve high esthetics with freehand bonding techniques Introduction Natural, restored or orthodontically enhanced smiles may present esthetic deficiencies that require treatment.1, 2, 6 However, the search for a perfect smile should note drive the clinician to use primarily invasive solutions such as veneers and crowns to resolve all esthetic anomalies, since such pro- cedures will have a negative impact on the long-term tooth bio-mechanical behavior and treatment cost. The freehand option, which is more con- servative and cost-effective, should then always be considered as our first choice, if feasible.3, 4, 5 In this context, composite resins represent the mate- rial of choice for young patients and less privileged people, or in any case those who require a strictly conserva- tive approach. The natural layering concept has enabled this objective to be achieved in a predictable way, by incorporating newly acquired knowl- edge about natural tissue optical properties into contemporary com- posite systems. This advance can be regarded as a milestone in operative dentistry as it will give direct compos- ite application a tremendous input, helping a larger number of our pa- tients to receive both conservative and highly aesthetic restorations; this concept was described as the “bio- esthetic” approach. The aim of this article is to illustrate the bio-esthetic philosophy and Natu- ral Layering Concept (NLC), applied to solve two advanced esthetic cases. ddietschi@genevasmilecenter.ch Pre & post-operative views of a smile restored with direct composites veneers, demonstrating the poten- tial of a free-hand approach and new composite technology. — Dr. Didier Dietschi, D.M.D, Ph.D, Privat-Docent, is a senior lecturer, Department of Cariology & Endodontics, School of Dentistry, University of Geneva, Switzerland.
