Bio-Emulation Symposium 2020

Over the last decade, there has been a profound interest in newer photographic illumination techniques aimed at increasing the accuracy and objectivity of dental diagnostic ability, shade evaluation, and laboratory communication.

In order to minimize the user-dependent errors in the clinical practice, it is necessary to develop reproducible imaging modalities and objective image analysis methods. Reflective cross polarized light photography
mitigates unwanted specular reflections and hot spots in addition to spectral highlights which obscure the fine details of hard and soft dental structures whilst providing a high contrast/hyper-saturated dental image to be objectively analyzed. This imaging technique which is non-contact and non-invasive is used to enhance the visibility when assessing dental images and has many translation applications.

You will learn:

• To distinct between reflective and transmissive cross polarized imaging modalities.
• To expand upon the spectrum of applications of cross polarization.
• To understand the direct benefits of cross polarization imaging in the clinical and technical realms.

Consistent shade matching of indirect restorations with natural dentition remains a great challenge even for the most experienced of experts. Numerous factors which take adverse effect on the clinical outcome have long been identified. They include operator dependency (subjective shade selection and evaluation), insufficient shade guide coverage of the range of natural tooth shades as well as considerable inconsistencies among manufacturers’ shading regimes. The eLABor_aid® system was developed to combat these limitations by enabling objective shade communication using cross polarized dental photography in conjunction with a new and innovative digital work flow that will allow the dental ceramist to formulate an individual shade recipe and to measure its accuracy with the help of a digital try-in of the build-up prior to firing. Learn about the future of shade management: capture, calibrate, and create!

You will learn:

• About traditional shade communication using visual assessment and what the pros and cons are.
• To understand metamerism and its origin.
• To use a digital single lens camera (DSLR) for objective shade quantification and communication without the use of shade guides.
• About practical realization of layered, indirect restorations and clinical examples. 
• About clinical applications of the eLABor_aid® protocol for bleaching control.

A totally interactive dialogue between two practitioners about early diagnosis, diagnostic tools, treatment strategy, protocols, and plan B. Clinical situations with both success and failure will help to develop a step by step approach. Flowchart galore and decision-making revisited.

You will learn:

• To recognize early signs of structural cracks.
• To increase predictability of proposed treatments.
• To control damage and limit collateral damage.
• To address different types of cracks.
• To remove all the obstacles that get in the way of good patient communication.

Dentistry is one of the most demanding professions known today. The practitioner needs both knowledge, understanding, and skills in what are often difficult treatments. How can magnification help? What types of magnification do we have today? What are the advantages and disadvantages? Is there a relation to quality? What are the real challenges of working with magnification? Is magnification alone enough? This presentation offers a different view on what we know and do every day.

It will be an interactive dialogue with the participants allowing for a real understanding of what is crucial in our everyday practice. A quiz will make learning fun.

You will learn:

• The real importance of magnification.
• To transform small things into big differences.
• To increase your clinical performance by enhancing your decision making.
• To choose the right magnification for you needs.

Restoration of large defects in the posterior region with a direct composite restoration is possible, although this is not an easy task for the dentist. The most durable, minimally invasive restoration of posterior teeth with large defects is the indirect bonded partial lithium disilicate glass ceramic restoration (onlay, partial crown). During this presentation, the new concepts of indirect partial bonded restorations in the posterior region will be discussed going from preparation – immediate dentin sealing, material selection and cementation.

You will learn:

• How to think in an adhesive way during preparation for adhesive partial prosthodontics treatment plans.
• How to perform a real adhesive preparation in a simple and clinically effective way.
• How to define limits of adhesive treatment plans.
• How to build a high-quality and long-lasting hybrid layer.

Aesthetic restorations that involve one single upper central incisor represent a great challenge for both dentists and technicians. To achieve optimal results with the minimum number of try-in tests or repetitions, it is necessary to perform a systematic and exhaustive shade analysis. Advanced photographic techniques need to be used for this task, including different kinds of illumination and precise calibration of RAW files.

Restoration material and technique selection depend on diverse factors such as the age of the patient, extension of the restoration, shade complexity, operator skills and the aesthetic requirements on the long term. Today, both composite and ceramic represent valid options for restoring such cases, but a clear shade selection strategy must, however, be defined for both materials. Ultimately, a successful treatment will always be the outcome of good communication with the patient and a perfect teamwork between the dentist and technician.

You will learn:

• The aspects to consider regarding material selection for single central restorations.
• Advanced photographic techniques for accurate shade analysis.
• Shade selection strategies for both composite and ceramic.
• Step by step on single central restorations with composite and ceramic.
