Bone Morphogenetic Proteins, A Realistic Alternative to Bone Grafting<br>
LOD-054-00
Dr. Ulf Wikesjo
Surgical placement of oral implants is governed by the prosthetic design and by the morphology and quality of the alveolar bone. Often, implant placement may be difficult, if at all possible, due to alveolar ridge aberrations. In consequence, prostheticly dictated implant positioning commonly entails bone augmentation procedures. One objective of our laboratory is to evaluate the biologic and clinical potential of bone morphogenetic proteins (BMPs) including rhBMP-2, rhOP-1/rhBMP-7, rhGDF-5, other candidate biologics, bone biomaterials, and devices for alveolar ridge augmentation and implant fixation. This presentation will discuss the unique biologic potential, the clinical relevance and perspectives of BMP technologies for alveolar bone augmentation and oral implant fixation, in particular the development of a unique bone-inductive oral implant. This presentation will also address merits and explain short-comings of current treatment protocol including bone biomaterials and guided bone regeneration (GBR). BMPs have an unparalleled potential to augment alveolar bone and support implant osseointegration and long-term functional loading. Inclusion of BMPs for alveolar augmentation and osseointegration will not only enhance predictability of existing clinical protocol but radically change current treatment paradigms. Inclusion of the bone-inductive oral implant in the treatment panorama may make 'grafting' and GBR procedures altogether obsolete.

Perio-Prosthetic Considerations Around Dental Implants<br>This course will discuss surgical and restorative concepts, procedures and solutions to improve the soft tissue emergence profile of implant and pontic sites in single implant restorations and implant bridges. The restorative choice of implant design and abutment material will be discussed and particularly the evidence of using Zirconia abutments as stable base for soft tissue esthetics and long term implant results.<br><br>The concept of using a concave or flat preplanned abutment via the cad-cam route and via the prefabricated route will be discussed and the steps preventing removal of abutments during the restorative phase.<br><br>This course will teach the restorative dentist the new concepts of zirconia abutment materials, the concave or flat abutment design and the immediate or early placement of the final abutment.

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.

Dr. Didier Dietschi
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.
Esthetic Restorations - All-Ceramic Advances for Single and Multiple Teeth
LOD-039-00
Dr. Bernard Touati
The use of CAD -CAM metal-free ceramic materials allows to achieve excellent esthetic results in the anterior and posterior area for crowns bridges and veneers fabrication. Material selection with the dental ceramist is fundamental in management of complex rehabilitation cases. Several clinical follow-up of ceramic and alumina and zirconia systems indicate the adequacy of these materials for anterior and posterior restorations. Clinical and technical suggestions for obtaining esthetic and durable results will be supplied.
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.
