Posterior Composites Restorations (Direct and Semidirect Techniques)
LOD-043-00
Dr. Didier Dietschi
The reduction in the carious disease incidence and the growing concern of patients for potential toxicity of metals and for dental aesthetics, have called the profession for developing restorative options adapted to new demands. Composites and adhesive techniques have then become the foundation of modern restorative dentistry, following tremendous improvements in material mechanical performances, wear resistance and aesthetic potential. Composite resins are currently used in a broad range of situations, including the treatment of initial decay to the restoration of extended and serial cavities, or the adhesive luting of ceramic work-pieces. However, polymerisation shrinkage of the resin matrix remains a crucial problem and still imposes certain limitations for the use of direct techniques. Therefore, other restorative options such as semidirect and indirect techniques have to be considered for large and deep cavity configurations. The lecture will overview decision criteria for the treatment of posterior teeth, the main restorative options at hand and will provide a comprehensive description of clinical procedures.

Different types of discoloration, some of displasic origin and others from acquired pathologies or tissue aging can be improved or sometimes fully corrected by bleaching. Bleaching aims to remove or treat several types of dark stains. The lecture will emphasize on the principles, application methods and potential indications of the various bleaching techniques at hand. All different bleaching protocols have potential to lighten tooth colour but not at the same level of efficacy; information will be provided as regard the likely indications for power / chair-side bleaching and other home bleaching methods. Attendees will also learn how to integrate chemical treatments in a comprehensive approach of aesthetics, which ultimately help us creating beautiful and attractive smiles without unnecessary tissue sacrifice.

The dramatic improvement in the overall population oral health as well as the growing concern of patients for tissue preservation and dental aesthetics has rejuvenated 'free-hand bonding' and made it a primary treatment option for the anterior teeth. Today, composite resin restorations offer conservative, biological and esthetic solutions to many problems, which formerly could only be approached by expensive and more invasive ceramic restorations. However, composite systems are based on different layering concepts and as a consequence, the restoration esthetic potential is strictly linked to a perfect understanding of the shading concept and optical properties of the composite masses in relation with those of natural tissues.<br>Based on a thorough observation of natural esthetics and the application of the so-called 'natural layering', together with an appropriate selection of composite brands, the clinicians can produce beautiful natural like direct composite restorations. The lecture will cover fundamental knowledge about colour and optical properties of natural tissues, will overview the indications of composite restorations in the front teeth and will provide a comprehensive description of clinical procedures.
Endodontic Access and Negotiation - Breaking & Entering
LOD-038-00
Dr. L. Stephen Buchanan
Technological advances in shaping and filling root canal systems have resulted in extremely consistent and ideal outcomes making those procedures more science than art form. However, cutting access cavities, finding all the canals in a tooth, and negotiating them to their full apical extents still requires developed skills and careful attention to detail. Ironically, many clinicians consider the access preparation and root canal negotiation those things we do to get to the important stuff afterwards this is ironic because when a mistake occurs during these initial phases in treatment it is often impossible to recover. Loss of structural integrity, perforations, missed canals, blocked canals, ledged canals and broken files are just some of the negative outcomes that occur when access and negotiation procedures go awry.<br><br>With adequate radiographs, the right access instruments, ultrasonic handpieces, lubricants, apex locators, and a predictable negotiating technique, artful outcomes can and should be the expected result when we head into a root canal space. Dr. Buchanan will show, in a step-by-step manner, the concepts, instruments, and techniques needed to set the stage for endodontic success using CT reconstructions of endodontic anatomy, video footage shot through an operating microscope, and radiographs of clinical cases.
Endo or Implant - Rational decision making from an Endodontist's viewpoint
LOD-029-00
Dr. L. Stephen Buchanan
As an Endodontists who places implants, Dr. Buchanan presents a uniquely balanced argument for when to save teeth with endodontic therapy and when the patient will be better served by replacement of the tooth with an implant. Dr. Buchanan will first explain the procedural advances available from endodontic specialists to save many teeth previously thought to be unsalvageable, including microsurgery, MTA root repair material, ultrasonics, and state-of-the-art shaping, cleaning, and 3D obturation technology. Then he will discuss how the structural integrity of roots greatly affects the long term prognosis of endodontically-treated teeth and methods for maintaining the inherent strength of teeth being saved with RCT. Finally, Dr. Buchanan will explore the advantages and satisfaction of a multi-disciplinary approach to treatment planning with an emphasis on the new trend of endodontists to view themselves as understructure specialists.
Challenging Composite Restoration With Free-Hand-Bonding - An Illusion Became Reality
LOD-008-00
Dr. Didier Dietschi
The growing concern of patients for tissue preservation and oral aesthetics has rejuvenated 'free-hand bonding with composites' and made it a primary treatment option for the anterior teeth. This lecture covers fundamental knowledge about color and optical properties, different treatment options with composite restorations, and provides a comprehensive description of clinical procedures.
