Presentation topics and presenters include

  • Prof. Dr. Junji Tagami, Tokyo Medical and Dental University – Japan: Saving Hopeless Teeth with Adhesive Technology
    • Clinical performances of the direct composite resin crown and bridge are shown and the factors affecting the performance are discussed. Some tips for success obtained from the long term clinical cases are also discussed.
  • Prof. Dr. John Sorensen, University of Washington School of Dentistry: A Critical Analysis of the Digital Workflow for Adhesive Ceramic Restoration
    • The synergistic interaction between modern material systems, digital technologies and software developments have propelled enormous advancements in both conventional and implant prosthodontics. Dr. Sorensen will review the current state of in vitro research and clinical trials from around the world on adhesive CADCAM ceramic restorations. He will detail a clinical trial at the UW on 50 posterior CADCAM adhesive ceramic restorations performed completely digitally. Clinical outcome measures documenting ceramic preparation design, optical impressioning, delivery adjustment and cementation, marginal adaptation, and clinical performance analyzed by Optical Coherence Tomography (OCT) and IOS will be explored in detail.
  • Dr. Grant Chyz, Private Practice, Seattle, Washington: Structural Adhesive Restorative Dentistry
    • Structural Adhesive Dental Restorations are the next step beyond Bioemulation and Biomimetic dentistry. SADR are based on a desire to preserve sound tooth structure – especially sound peripheral tooth structure – by managing the careful removal of failing fillings, including a focus on caries, cracks, cavity design, and microfractured enamel. Proven bonding protocols are utilized with perfect isolation. Both continuous UHMWPE and short fiber composites may be utilized to enhance restorations, support cusps internally, bridge dentin cracks, improve bond integrity, reduce the effects of polymerization shrinkage and arrest or deflect cracks. Finally, restoration contours, esthetics, margins and occlusion are in the hands of the clinician. This session will focus on restorative success with structural adhesive fiber-reinforced direct restorations.
  • Dr. Alan Atlas, Private Practice, Philadelphia; Penn Dental Medicine: The Class II Posterior Composite Restoration: The issues are in the details!
    • Technique errors, incorrect material selection/placement and poor patient compliance will expedite failure of posterior composite restorations. This presentation will provide a current scientific update about what modifications are needed in dental school education and private practice to improve skill, efficiency and outcomes in the Class 2 Posterior composite workflow. Step-by-step novel protocols for preparation, placement and finishing to achieve better margins, contacts and reduce post-operative problems will be demonstrated with video provided by Dental Microscope HD Video.
  • Dr. Marcelo Giannini, State University of Campinas – Brazil: Simplified Adhesives and How Bleaching Agents Interfere with Dental Bonding
    • The simplification of adhesive procedures is a trend, but doubts persist about the quality of adhesion with simplified adhesives. Besides, esthetical procedures, such as bleaching, interferes with bonding because the remaining oxygen species (ROS) residues left from hydrogen peroxide may affect enamel/dentin adhesion and diffuse through the adhesive interface.
  • Dr. Alireza Sadr, University of Washington School of Dentistry
  • Dr. Jorge Aravena, Private Practice and Diego Portales University – Santiago, Chile: Five-Year Clinical Experience in the Reconstruction of Anterior and Posterior Teeth with Structural Compromise – No Post, Conservative, Adhesive, and Structural Solutions
  • Dr. Jihyon Kim, Private Practice, Seattle, WA: Biopreservation with Direct Adhesive Dentistry: Stop the Grind
    • Tremendous material advances with composite resins have garnered its general acceptance as a sound option for small to moderate restorations or minor smile enhancements. However, lack of confidence in material longevity or aesthetics, clinician skill, or technique continues to fuel a reliance on indirect solutions.Direct methods for replacement or addition allow maximum preservation of sound tooth structure while indirect methods require a path of draw and insertion or minimal material thickness. Confidence with direct adhesive solutions may expand options regarding tooth restorability, life span, and space management ultimately affecting treatment algorithms and interdisciplinary treatment discussions.
  • Dr. Roozbeh Sadrimanesh, Private Practice and Tehran University of Medical Sciences: Rehabilitation of Worn Dentition with Adhesive Ceramic Restorations: Simplified Digital Workflow
