Risks Endangering Bone Stability Around an Implant
LOD-208-00
Dr. Georg-H. Nentwig
The risks that endanger bone stability around an implant can be related to trauma, loading, anatomy, implant, reconstruction, or the patient. This lecture will provide hints and scientific background about each one of these aspects so that you can manage and even avoid these risks.<BR><BR>Bone stability is the key for long-term success of an implant. But, there are two areas that must be identified in maintaining this stability. We will emphasize the importance of the implant abutment area where the bone is adjacent to the soft tissue. This bone is critical for supporting the soft tissue and for ensuring the health of the soft tissue and avoiding bacterial contamination.<BR><BR>This lecture will show you what you can do to improve a weak bone to avoid an early functional mistake or failure of the total reconstruction. We figured out that we can add, after the static phase, after the second stage surgery, after the load has started, a bone training phase that can improve the original weak structures so much that you can rely on it's stability even if you apply a more risky restoration.<BR><BR>We will discuss how to avoid esthetic failues, an unpleasent situation for both the patient and the dentist, that are often due to lack of bone right from the beginning.<BR><BR>Finally we will discuss the option to place an implant in a sub-crestal position which is only possible if you use an implant that has a stable cone connection. The cone connection will avoid any bacterial release, and will therefore avoide any bone loss in the cervical region caused by this bacteria contamination. With this concept we can achieve long lasting esthetic results.
The Biodynamics of Osseointegration Facts and Clinical Implications
LOD-207-00
Dr. Peter Schupbach
Dental implants are placed into the alveolar bone, with the expectation that they become osseointegrated and that the periimplant mucosa will heal to the abutment surface and fulfill the primary functions of the periodontal tissues, which are attachment and protection of the soft tissue and the underlying bone.<BR><BR>This requires that the rather rigid ankylotic like connection between implant and bone replaces functionally the sophisticated suspension via the periodontal ligament as offered by the evolution and, that the structural framework of the periimplant mucosa matches the architecture of the gingiva. <BR><BR>The context of an understanding of the elicited host site interfacial healing response will be reiterated for the time period immediately following implant placement up to long term behavior.

Retreatment in Endodontics - From Difficult to Complicated Cases
LOD-197-00
Dr. Constantinos Laghios
In this lecture we will describe the relationship of the root canal anatomy to the lesions that are developed at the periradicular area.<BR><BR>We will also give all the details how to remove safely different kind of materials like gutta-percha, silver cones, broken instruments, posts and pastes.<BR><BR>Details will be given as to avoid any mistakes that would possibly endanger the retreatment perforations and absorptions will be treated in a fast, predictable and simple way.
Predictable and Successful Maxillary Sinus Augmentation
LOD-192-00
Dr. Toshiro Sugai
In this presentation, we will identify safer and more predictable maxillary sinus augmentation procedures. We will discuss how to utilize CT imaging to evaluate and interpret the 3D anatomy of the sinus, including ostium, superior alveolar artery, and septa. Dr. Sugai will describe how to predictably lift the sinus membrane and avoid complications.

Ridge Augmentation Using rhPDGF Growth Factors
LOD-121-00
Prof. Massimo Simion
This lecture covers the topic of ridge augmentation using the line of growthfactors termed rhPDGF (Gem-21) mixed with xenograft, TCP and autograft for implant placement. The scientific background and the first clinical cases are discussed and demonstrated. The new bone graft material shows to be an enhancement to the current technique of GBR.
The Success of Endodontic Therapy - Healing and Function
LOD-089-00
Dr. Shimon Friedman
The Success of Endodontic Therapy - Healing and Function<br>Over 30% of root-filled teeth in the population present with persistent disease, suggesting an extensive need to manage the affected teeth. Treatment options include extraction and replacement, orthograde retreatment and apical surgery, and selection between these can often be complex. When the patient is motivated to retain the affected tooth, a key consideration is the prognosis, or potential for healing; therefore, the prognosis should be communicated to patients in a clear and objective manner. This lecture focuses on the prognosis of orthograde retreatment and apical surgery.<br><br>Inconsistent reports on the prognosis of orthograde retreatment and apical surgery, in contrast with consistently favourable reports for implant-supported single-tooth replacement, have caused considerable confusion in the profession. To reliably reflect the prognosis, studies must conform to design and methodology criteria consistent with an acceptable level of evidence. These criteria are met by only a few studies on retreatment and apical surgery. This lecture identifies the studies that provide the best evidence and outlines the prognosis of retreatment and apical surgery in regards to healing and symptom-free function of the treated teeth. Furthermore, specific clinical factors are highlighted that may influence the prognosis.
Endodontic Rotary Instrumentation - How to achieve maximum efficiency while eliminating failure
LOD-085-00
Dr. John T. McSpadden
There may be more instrumentation technique recommendations than there are endodontic instruments available. Obviously, all cannot be the 'best' approach. Are these techniques confusing motion with accomplishment and time with safety? This presentation describes 6 basic principles that enable the practitioner to maximize endodontic rotary instrumentation in terms of effectiveness, efficiency and safety for any type endodontic file available today and as they become available in the future. Saving valuable time and eliminating pernicious stress are the result.
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.
