Emulate Nature with Conservative Dentistry
Live CE Webcast, • Friday, October 29, 2021 • 10 a.m. - 1 p.m. ET
Achievement of aesthetic anterior restorations that resemble natural teeth represent a great challenge for our daily practice. The goal of this presentation is to offer multiple reasons and demonstrate through meticulously documented step -by- step cases how the modern composite materials and bonding are a perfect treatment choice in many clinical situations. Concepts such as isolation, air blocking, resin adaptation, gap avoidance and layering fiber-based composite restorations will be reviewed. Restorations that take these concepts into consideration are more likely to be a true success on the difficult process of emulating nature with dental materials.

Bio-Emulation: Histo-Anatomic Analysis and Dynamic Light Observation for Anterior Restorations
Javier Tapia-Guadix, DDS
Achievement of aesthetic anterior 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 histo-anatomic principles is essential for a better material and shade selection strategy 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.

Learning Objectives:
• Gain a better understanding of optical properties of tissues and materials.
• Discuss advanced photographic techniques for shade analysis.
• Analyze material selection criteria based on patients age.
• Determine strategies for avoiding problems in shade selection.

An Additive Approach to Restorative Care: Decoding Healthy Esthetics
Abdi Sameni, DDS
Since the birth of restorative dentistry, the devoted practitioner has studied, appreciated and respected the value of the natural tooth. In that capacity, the dentist has always tried to follow the proven-at-the-time techniques and materials to protect, preserve and restore their patient’s natural teeth with the least amount of collateral damage. Advances in adhesive technologies, combined with our deeper understanding of the natural tooth’s histological and geometric make up has allowed the profession to provide extremely conservative and life-like restorations with almost no collateral damage. Despite these advances and possibilities however, many practices are still uncomfortable to embrace and engage in the unique advantages that this conservative dentistry can bring to their practices and patients. The common global belief in dentistry (for both patients and dentists) is that indirect restorations are superior to direct restorations . Add to that the fee-versus-effort disparity and it becomes no surprise why “crown& bridge” is the life line of most restorative offices. The goal of this presentation is to offer multiple reasons and demonstrate through meticulously documented step -by- step cases how the modern composite materials and bonding are a perfect treatment choice in many clinical situations.

Learning Objectives:
• Properly select cases that are ideal for direct composite veneering versus indirect porcelain veneers.
• Describe the long term benefits of preserving tooth structure for the future.
• Perform simple layering for beautiful optical effects that rival natural teeth.
• Develop the language skills and the tools to educate their patients for a higher case acceptance.
• Develop a fee structure to make direct restorations as profitable as indirect procedures.

11:30 AM - 12:15 PM ET
How Far Can We Go with Additive Resin Composite Restorations Today?
Mehrdad Razaghy, DDS
Can direct restorations be as promising as semi-direct & indirect, when dealing with large posterior defects? Indications for direct composite restorations have changed drastically over the past 5 years and our goal during this lecture, is to explore and deeply understand the new possibilities through science and clinical examples. During this lecture, we aim to educate all participants on the possibilities of achieving quality and esthetic direct and additive restorations that can be as promising as semi-direct and indirect techniques. We will be reviewing a few clinical cases and studies through which we will shed light on the concept of c-factor (or Volume factor) and will explain how utilization of fiber re-enforced composites has revolutionized direct resin restorations. We will be reviewing a simple yet essential checklist, through which we can achieve long lasting and quality composite restorations while avoiding the most common complication of large resin composite restorations; shrinkage induced cracks. Concepts such as Isolation, air blocking, resin adaptation, gap avoidance, and layering fiber-based composite restorations will be reviewed.

Learning Objectives:
• Discuss mechanical performance of direct, semi-direct, and CAD/CAM approaches for large MOD composite-resin restorations.
• Minimizing layering gaps in multi-layered direct composite restorations.
• Perform simple layering for beautiful optical effects that rival natural teeth.
• Discuss short fiber-reinforced direct restorations.
• Review a history of different approaches to optimize large direct restorations.

Speaker Information
Javier Tapia-Guadix, DDS was born in 1978 in Madrid, Spain. He finished dental school at the European University of Madrid in 2003. Working then as associate professor in the prosthetics department during 2004. In 2005 he started his career as professional computer graphics artist, focused on illustration, animation and application development. He received the Collegiate Merit Award by the Spanish College of Dentists from the 1st Region in 2005, for his collaboration in the commission of new technologies. In 2011 he founded together with Panaghiotis Bazos and Gianfranco Politano the Bio-Emulation group. He actively collaborates as invited professor with several universities across Europe. In 2017 he became official reviewer for the International Journal of Esthetic Dentistry. Javier works in private practice in Madrid, focused on restorative dentistry and aesthetics. He is an international lecturer and has published several articles in restorative dentistry, dental photography and computers in dentistry.

Abdi Sameni, DDS is a Clinical Associate Professor of Dentistry at Herman Ostrow School of Dentistry of USC, and is the president and developer of the International Restorative Dentistry Symposium of Los Angeles.
