Tucker Lecture of Excellence
"The Digital Workflow for Gold Restorations"
Michael Hohaus, PhD
Private Practice, Düsseldorf, Germany
Synopsis: The techniques commonly employed with the preparation and placement of cast gold restoration have been adapted since introduction by Dr. Richard V. Tucker and are commonly referred to as the Tucker Technique. With the advent of milled digital dental technology, materials used to solve complex treatment cases have significantly expanded. It offers a simplified and time-saving process in the practice as well as the laboratory in addition to improve patient comfort and satisfaction. The integration of these techniques into practice requires a high level of motivation and a great deal of time for the entire dental team to develop a time efficient workflow which benefits all. The adhesive technique offers the possibility of minimal or non-invasive restorations without further tooth structure loss for retention. In the renewal of defective restorations, the morphological structure of the lost tooth substance and the protection of the remaining, fragile structures play a decisive role. Material specific properties such as minimum layer restoration thickness and loads must be taken into account in cavity design. Recommendations on the use of materials, whether gold, ceramics or composite in addition to the applications of direct or indirect techniques, should be based on the needs and necessities of the patient as well as the amount of remaining hard tooth substance. Decision workflows concerning material choice and a technique highlighting the benefits of a milled gold technique will be presented and discussed to improve patient outcome.
1) the benefits of the digital workflow and the milling of gold restorations
2) Instrumentation used for scanning
3) Special techniques adapted for scanning and milling
4) Laboratory benefits

"Root Caries: Myths and Realities"
Hendrik Meyer-Lueckel, DDS, MPH, PhD
Department of Operative, Preventive and Pediatric Dentistry in Bern, Switzerland
Synopsis: Root caries is still surrounded by several myths regarding its etiology, diagnostics, prevention as well as non- and minimal invasive treatment. The lecture will give insights into a more tooth preservative approach instead of early drilling, crowning or inserting implants after extraction..
- More teeth, more seniors = more root caries in future years
- Risk-oriented non-invasive (preventive) therapy using highly fluoridated toothpaste with 5000 ppm F- is efficacious. Antimicrobials (i.e. CHX-varnish) only when biofilm is present.
- Creative preparation and restoration techniques warranted. Good moisture control = composite; as a compromise = glass ionomer cements.

43rd Buonocore Memorial Lecture
“Changing Operative Mindsets with Universal Adhesives and Cements”
Lorenzo Breschi, DDS, MS
Synopsis: Synopsis of the Presentation: The requirements that dental adhesive materials are expected to meet are becoming ever more demanding. An adhesive material should be versatile and suitable for universally bonding to a vast variety of substrates and restorative materials. It should be less technique sensitive, efficient in inexperienced as well as experienced hands, and indicated for simplified as well as more elaborate clinical procedures. In achieving these goals, the material must indeed remain reliable in the long term. Hence, modifications in the chemical composition of adhesive materials have been made in order to improve their bonding, mechanical properties and biocompatibility. These modifications are particularly evident in cases of universal adhesive systems and resin cements which bring adhesive dentistry one step closer to the above-mentioned goals. Considering the increased interest in these materials by the scientific community, their strengths and drawbacks should be examined and discussed in detail, providing recommendations for further development.
- Understand the modifications introduced in the compositions of universal adhesive systems and resin cements.
- Understand the in vitro and clinical performance of universal adhesive materials.
- Discuss future perspectives in the development of adhesive dental materials.

Currently there are many universal composite shades on the market. Each actual composite resin has differing chemistries, but the basic concept is particles included in each resin allow for the material to reflect the color of existing tooth structure. A study of several universal composite resins was completed looking at the shade match to ceramics. Data was gathered from dentists blindly evaluating the ability of these composite resins in shade matching. The results and applications of this study will be presented and considered.
1. Define the definition of universal shade composite resins and indications for use.
