The use of MTA in Clinical and Surgical Endodontics
LOD-082-00
Dr. Arnaldo Castellucci
Recently, Dr. Mahmoud Torabinejad of Loma Linda University, California, has developed a new cement named Mineral Trioxide Aggregate which appears to have all of the characteristics requested of the ideal cement to seal pathways of communications between the pulp and the oral cavity (mechanical and carious pulp exposures), and between the root canal system and the periodontium (iatrogenic perforations, open apices, resorbed apices, root-end preparations).<br><br>MTA is an endodontic cement that is extremely biocompatible, capable of stimulating healing and osteogenesis, and is hydrophilic. MTA is a powder that consists of fine trioxides (Tricalcium oxide, Silicate oxide, Bismute oxide) and other hydrophilic particles (Tricalcium silicate, Tricalcium aluminate, responsible for the chemical and physical properties of this aggregate), which set in the presence of moisture. Hydration of the powder results in formation of a colloidal gel with a pH of 12.5, that solidifies to a hard solid structure in approximately three-four hours. This cement is different from other materials currently in use because of its biocompatibility, antibacterial properties, marginal adaptation and sealing properties, and its hydrophilic nature.<br><br>The characteristic that distinguishes MTA from other materials used to date in endodontics is its hydrophilic properties. Materials used to repair perforations, to seal the retro-preparation in surgical endodontics, to close open apices, or to protect the pulp in direct pulp capping, are inevitably in contact with blood and other tissue fluids. Moisture may be an important factor due to its potential effects on the physical properties and sealing ability of the restorative materials. As shown by Torabinejad et al., MTA is the only material that is not affected by moisture or blood contamination: the presence or absence or blood seems not to affect the sealing ability of the mineral trioxide aggregate.<br><br>During the presentation, several cases of treatment with MTA will be showed. Aim of the presentation is to show the indications and the technique for the correct use of this relatively new material: how to seal an open apex, how to repair a strip-perforation under the microscope, how to protect a pulp exposure to perform a direct pulp capping, how to use MTA during surgery to seal the retroprep.<br><br>In conclusion, the viewers should be able to appreciate the advantages of this material, which made our treatments more predictable and gave us the possibility to save teeth otherwise condemned to extraction.

Clinical Pharmacology - What Every Dentist Should Know
LOD-072-00
Dr. Anthony Feck
Modern dentistry has expanded the arsenal of services to restore patients oral health and cosmetic needs like never before. These changes have corresponded to an increasingly complex medical environment where patients are presenting at a more advanced age, with more medical conditions, and taking more medications. Understanding the pharmacology as it relates to their systems and how the drugs they are taking, as well as those we intend to administer affect the patient, one another, and our planned treatment is necessary for a safe and successful outcome to our planned care.
Treating the Medically Complex Patient

The course will assist dentists in developing a plan to create a digital or chartless practice. We will look at the six components of a digital practice and how to make intelligent decisions for purchasing each component. We will also look at the process to integrate all of these components together.
Predictable Anterior Aesthetics with Veneers - Interdisciplinary Approach
LOD-055-00
Dr. Galip Gurel
Creating the precision in terms of the preparation, fit and the aesthetic final outcome with veneer restorations needs a detailed treatment plan which is unique to each case. Designing a new smile for a patient consists of many steps which are very important and if followed correctly, produce predictable success. The key to aesthetic excellence requires patient communication as well as the communication with the laboratory and the specialists from the beginning of the case till the end. This presentation will help the clinician to understand the clinical steps as well the patient communication steps.<br><br>In todays dentistry success depends on an interdisciplinary team work. Every member of the team (including the specialists, lab technicians and the patient) should be aware of the treatment planning and the end result from the beginning. Every effort should be spent to bring the teeth to their natural position on the dental arch, hence creating enough space for the restoration to be received so that the aim should be minimum tooth preparation.<br><br>After that stage, in order to achieve a very precise and predictable tooth preparation, wax-up, silicon indexes and related techniques such as APR (Aesthetic Pre Recontouring), APT (Aesthetic Pre-evaluative Temporaries) and preparation through the APTs are extremely crucial. This eliminates all the possible mistakes and destruction of the depth cutters that could have been done if the tooth was to be prepared without realizing the aging affects on the enamel (volumetric enamel loss) or their inappropriate teeth positions on the dental arch
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.
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.
