The Bio-Emulation approach as written in structural analysis and visual synthesis defined the new bases to consider for replication of natural tooth structures with composite resin. The penta_laminar concept represents the ultimate implementation of this philosophy: analysing different ageing stages to build a
dynamic shade concept that adapts to nature. However, feasibility of application of this concept is compromised by it’s intrinsic complexity, not accesible to all clinical conditions. By analysing the key factors of natural structure’s ageing process and applying this knowledge to the material selection, it is possible to
simplify techniques to make them approachable in all situations. From a bi-laminar technique to the penta_laminar technique we can learn to adapt our work in order to optimise the clinical outcome achieving cost-effective treatments to cover our patients needs and expectations.
