Minimally Invasive Concepts & Digital Dentistry- Where Are We Now?
CAD/CAM technology is one of the fastest evolving aspects in modern restorative dentistry. Major advantages of intraoral scanning and the digital workflow are patient´s preferences, superior mechanical performance of CAD/CAM materials as well as excellent fit of these restorations. The impaired machinability of many CAD/CAM materials has been a limitation for many years resulting in marginal chipping of minimally invasive restorations. But novel chairside milling devices are now available for faster fabrication times with protocols that are adjusted to the respective CAD/CAM material. Complex reconstructions still represent a great challenge for clinicians and dental technicians but digital workflows significantly facilitate these rehabilitations. Various tools were developed to evaluate the relationship between the different components of the face and to provide guidance for treatment planning as well as for the manufacturing of the final restorations. Advancements in CAD/CAM material systems, digital restoration planning and fabrication resulted in innovative treatment concepts for severely compromised dentition. Digital face scans and novel CAD/CAM applications offer a standardized manufacturing process, providing a reliable, predictable and economic workflow for chairside but also complex rehabilitations.

VertiCAD for Ceramic Restorations: An Innovative Treatment Concept for Veneers Restorations
The esthetic treatment through adhesive restorations has always presented a challenge in clinical practice. With the improvement of dental materials, many restorative options such as composite resins, all- ceramic crowns, and ceramic veneers have become available. The current challenge in restorative dentistry is to obtain excellent esthetic results while preserving the biological structures involved as much as possible. New generation all-ceramic restorations and adhesive systems allow a greater preservation of residual hard tooth structures, especially with regard to single elements. The constant development of the digital workflow enable the dental team to control many aspects of the restorative plan, increasing the predictability and the efficiency of the treatment. The lecture will be focused on a step by step procedure for strategical preservation of tooth structure in veneers preparation, showing also new trends and techniques in the digital workflow.

At the conclusion of this session, attendees should be able to: Recognize pros and cons of various types of ceramic veneer preparation, and the advantages and limitations of the feather edge preparation approach. Show the modern data collection and the matching of these in a virtual environment. Describe the digitally detected aesthetic parameters that can influence the design of our restoration. Discuss how perform a digital smile design in 3D, getting a lot more informations and checking them constantly.

Decision Making in Implant Prosthetics - What Have We Learned From Wrong Decisions and Complications?
For successful implant prosthodontics safety, long-term performance, costs and the esthetic outcome are the main factors for the decision making process. Important achievements in this field have undoubtedly been the introduction of digital impressions, 3D planning and designing softwares, 3D printing and CAD/CAM technology in implant dentistry. The digitalization process in implant prosthodontics has introduced a lot of new opportunities and material options, which help solving currently clinical and dental laboratory challenges. As many of these techniques are already available in clinical practice it is of great importance to evaluate the advantages and disadvantages of these techniques and materials in clinical applications. Hence, the aim of this lecture is to discuss and compare CAD CAM in prosthodontics from start to finish with the conventional workflow and conclude with the today?s recommendations.

- Evaluate the safety aspects of different type of implant reconstruction and to select the appropriate material and design
- Differentiate between the conventional and the CAD CAM workflow in implant prosthodontics
- Learn and understand the efficiency of the different type or workflows (conventional vs CAD CAM) and their advantages and disadvantages for the dentists and the dental technicians.

2 Decades of Esthetics Immediate Tooth Replacement: Mistakes Made, Lessons Learned
Esthetics immediate tooth replacement, a controversial, yet exciting treatment concept that was conceived more than 2 decades ago. While the concept has evolved over time, numerous debates had been dedicated to its validity. Now, 23 years later, questions remain: Does it maintain gingival esthetics? Does it work as well as implant in healed sites? Is it a viable option for replacement failing maxillary anterior teeth? This presentation will focus on pros and cons of esthetics immediate tooth replacement. More importantly, did we validate this procedure from lessons learned by mistakes made over the past 2 decades?

Immediate Dentoalveolar Restoration (IDR) - Preservation and Regeneration of the Natural Biology
The Immediate Dentoalveolar Restoration (IDR) is a surgical and prosthetical technique established to broaden indications for immediate loading on individual teeth. In this way, bone and soft tissue losses are reconstructed in the same surgical session of implant placement and provisional crown installation using bone graft harvested from maxillary tuberosity, reducing the number of interventions and keeping predictability on esthetic aspects. The IDR protocol was developed more than 13 years ago from the need to minimize the treatment time and morbidity of reconstructive procedures used in these cases in comprimiseed alveolar sockets.

In the lecture I'll discuss the scientific basis, the step-by-step technique, indications and bone biology. The IDR technique, which advocates minimally invasive surgery, flapless procedures, is presented as a viable and reproducible alternative.

It is presented several cases, which showed one or more compromised socket walls of the tooth involved, with or without changes of the gingival margin, with long-term of clinical, radiographic and CT scan follow-up.

SURFACE: Creating Natural Contours, Texture, Luster and Surface Color in Dental Restorations
The final touches of contour, texture, surface colorants, and luster can take average looking dental restorations and create an exceptionally esthetic result. These steps are critical to the success of dental restorations weather it is composite or ceramics. These skills are more necessary now than ever as monolithic restorations are now the predominate type of indirect restoration. The lecture will cover the esthetics of the individual tooth i.e. the unique form and texture patterns of Anterior teeth and color distribution patterns that can be somewhat mimicked with surface color. The lecture will detail the very specific armamentaria and techniques to create ideal ?Surfaces? both in Color and finish specically with the newer generation Monolithic Materials Cubic Zirconia and High Strength Glass Ceramics. As a bonus the presentation will cover specific materials and techniques to get Ideal surfaces on Composites, Porcelain, and even in wax as all materials require very different procedures and armamentaria.
