Bio-Emulation: 3D histo-anatomic analysis and dynamic light observation for direct restorations

Achievement of aesthetic restorations that resemble natural teeth represent a great challenge for our daily practice. Obtaining optimal results with the minimum number of adjustments or repetitions necessarily implies performing a systematic and exhaustive shade analysis. Understanding light interaction with tooth structures as well as proper 3D histo-anatomic relation between enamel and dentin is essential for an optimal shape and shade reproduction during restorative procedures. Properties such as light scattering, opalescence and fluorescence, as well as considerations to teeth ageing should always be incorporated into our selection criteria.
The dynamic light observation as defined in Bio-Emulation: Visual Synthesis represents the state of the art analysis of light interaction with tooth structures. As such it should become our reference not only for the shade analysis previous to our treatment, but also for the trustworthy final result. Only the restorations that could integrate with different kinds of light (i.e. cross-polarized, transmitted, ultra-violet, diffused, etc) can be considered a true success on the difficult process of emulating nature with dental materials.
The penta_laminar concept represents the ultimate implementation of this philosophy: understanding different ageing stages to build a dynamic shade concept that adapts to nature. By implementing this universal shade concept, it is possible to simplify the layering 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.

Key Learning points

  • Better understanding of optical properties of tissues and materials.
  • Understand the 3D spatial relation between enamel and dentin.
  • Learn advanced photographic techniques for shade analysis.
  • Material selection criteria based on patients age.
  • Layering techniques for composites following Bio-Emulation principles.
  • Selecting the proper shades for masking fracture lines and creating incisal effects.
