Comparison and Contrast of Direct vs. Indirect Anterior Restorations in Natural Teeth
LOD-159-00
Dr. Stratis Papazoglou
<p style="margin: 0px; text-align: justify;">This lecture involves the selection of appropriate treatment procedures for anterior aesthetic restorations. First we will review the anatomy of the tooth structure, not because we are going to actually mimic the natural tooth histology, but because we need to know the esthetic target. <br /> </p> <p style="margin: 0px; text-align: justify;"><br /> </p> <p style="margin: 0px; text-align: justify;">Our actual goal will be to create the illusion of the natural tooth using composite resin or ceramic materials with different translucency properties. This lecture will underline the importance of proper diagnosis, in formulation of the treatment plan based on patient age, patient preferences, economic limitations, sound scientific principles, and treatment philosophy of the operator. <br /> </p> <p style="margin: 0px; text-align: justify;"><br /> </p> <p style="margin: 0px; text-align: justify;">Example cases involve closing diastemas with direct procedures, restoration of fractured anterior teeth, restoration of discolored teeth, re-restoration of previously restored teeth, teeth with wear and erosion, teeth with size, shape, and position problems.</p>
Conservative Rehabilitation of Abrasion & Erosion Cases
LOD-147-00
Dr. Didier Dietschi
This Lecture will review the use of direct and indirect adhesive techniques to solve complex cases involving abrasion and erosion. It will focus specifically on the use of composites. Timely use of composites is crucial, and waiting until the problem becomes too severe will often cause crown and other extensive preparations to be necessary.
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.
One appointment Inlays/Onlays; Durable, Economical, and Appreciated
LOD-087-00
Dr. Lorin F. Berland
Patients are demanding aesthetic, yet reliable alternatives to the replacement of their defective amalgam restorations. Learn the rationale for replacing defective amalgam restorations while conserving and reinforcing the remaining tooth structure. Systematic methods will be detailed about amalgam and caries removal, insulation, proper preparation, impression taking, inlay/onlay fabrication, and final cementation techniques.
Composite Resins in Contemporary Practice
LOD-086-00
Dr. Ronald Jackson
The public today want their dentistry less invasive and more aesthetic. Direct composite resin does both and its use in dentistry is rising rapidly. However, these materials have undergone significant evolution in recent years and dentists are challenged to keep current. In addition, esthetic standards have been raised and quality outcomes redefined by todays educated patient. This presentation will focus on understanding the new composite materials specifically developed for anterior and posterior use and illustrate the key elements for their successful application.
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.
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
