Lasers in Contemporary Implant Dentistry - Part 2
LOD-238-00
Dr. Glenn van As
Part 2 of 2: Lasers in Contemporary Implant Dentistry by Dr. Glenn van As<br /><br />Part 1 (LOD 237-00) of this two part series will look at four things that can happen with laser tissue interactions: Scatter, Transmission (or Refraction), Absorption, and Reflection. This will help us understand the physics and science of lasers. We will look at the several different wavelengths available for implant dentistry, and which one might be appropriate for your practice. This lecture will present a protocol that will help you determine where lasers can fit in to implant dentistry. And, finally, we will discuss how lasers can impact before you place your implant, and during the placement of your implant.<br /><br />Part 2 (LOD 238-00) of this two part series will discuss the role of lasers after the implant has been placed. We will demonstrate how it can be used to improve healing. It can be used during uncovery. It can be used in periimplant tissue removal, and even in the exciting world of periimplantitis. Clinical cases will be presented showing hard-tissue lasers being used for decortication as an alternative to traditional means. We will focus on why an electrosurge may be damaging to your implants, and may cause you more problems than benefits, and why a diode-laser may be your treatment of choice. This lecture will conclude with what may be the future of lasers, and how Erbium lasers might be able to be used in periimplantitis to not only remove biofilms and surfaces like TiUnite, but to actively allow for reosseointegration to occur.

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.
Retreatment in Endodontics - From Difficult to Complicated Cases

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.
YSGG Laser Precision in Periodontal Plastic Surgery
LOD-059-00
Dr. Bobby Butler
Lasers have been used in dentistry for many years. Mostly they have been used with soft tissue procedures. Recently the Er,Cr:YSGG laser has been shown to be safe and effective in osseous procedures. Many cosmetic dentists have been using lasers for esthetic crown lengthening procedures, but most of these cases are simple gingivectomies and not true crown lengthening procedures. Complications can occur without understanding the biologic width and different periodontal biotypes. This presentation will discuss current and future applications with the Er, Cr: YSGG laser with periodontal surgical procedures. The focus will be its use in closed and open esthetic crown lenghtening procedures. Discussion with case selection and osseous biotypes with be stressed. Other applications involving osseous augmentation procedures, harvesting osseous blocks, ridge splitting and lateral sinus wall procedures, will also be briefly discussed.
