Dr. Eduardo Mahn, Chile
Dr. Mahn graduated from the University of Chile in 2004. He received the German DDS, one year later. The New York University College of Dentistry certified him as Implantologist in 2007.
In 2008, he published his doctorate thesis in 2008 titled Osseointegration of zirconia implants, an in vivo study” and got his doctorate degree in 2010 from the University of Duesseldorf, Germany. Between 2007 and 2009 he worked for Ivoclar Vivadent at the ICDE (International Center for Dental Education), Schaan, Liechtenstein and he is presently a guest lecturer at several universities. He is the author from a variety of articles and has been lecturing intensively about Esthetic Dentistry and Implantology in more than 50 countries.
Dr. Mahn is presently the Director of Clinical Research and the Director of the Program of Esthetic Dentistry at the Universidad de los Andes, Chile. He is also a partner at the CIPO Clinic in Santiago, Chile, emphasizing comprehensive implantology, restorative and esthetic dentistry.
Since a few years we are facing the fact that more and more often patients are asking for dental veneers without preparation, non-prep veneers or „contact lenses“ for teeth, that will make them look better, whiter and younger.
Years ago, patients came to us because they were sick or because they were in pain. They were easily accepting our treatment plan and following our advices. But something changed over night and some of us were caught unprepared by this change. Patients are now not only better informed but also skeptical because they compare different sources of information, and we are just one of them. In one of the fields where the shift is more accentuated is in esthetic dentistry, specifically regarding veneers. These effects are happening because of mainly two reasons, first, the very aggressive and dishonest marketing of some dental companies and clinics, and second, because patients can find lots of misleading information free on the internet. The truth is, that there are few cases where minimal prep veneers will be easier than more traditional options .There are many advantages when we do not remove tooth structure, but also many drawbacks that need to be addressed. In fact, a minimal chamfer need to be even more precise and clean that a traditional one, since double margins will be more critical.
Several aspects need to be assessed before such a treatment is offered to a patient. Size and contours of the teeth before and after the treatment need to be compared. Even extremely thin veneers of 0.2 or 0.3 mm can dramatically change the appearance. Also the desired colour is a factor to keep in mind, since severe discolorations might not be completely covered. In case of diastemas, the path of insertion and the presence of undercuts might impede the insertion of them and too translucent ceramics might look greyisch.
These and other factors will be discussed during the course based on fully documented clinical cases.

Course Description
The course will cover the necessary knowledge to master preparations for inlays, onlays, crowns and endocrowns done with CAD-AM technology. Cuspal coverage will be discussed and different designs demonstrated. Silicon guides are going to be made. Teeth 16, 14, 26, 27 and 24 are going to be prepared and temporized. Different burs are going to be shown, and step by step preparation techniques are going to be demonstrated. Novel techniques and instruments like the sonic tips, step cutting burs and others are going to be presented. Finally, temporaries are going to be made and a short cementation demo performed.
All the steps will be shown by the instructor with an HD camera with high magnification for explanation of all the details.

Course Objectives
The participants will learn:

About the advantages and disadvantages of CAD-CAM technology.
To prepare inlays and onlays
When cuspal coverage should be performed
To prepare crowns and endocrowns done with CAD-CAM technology
To make state of the art temporaries for the different indications
