The rapid development of CAD/CAM technology is already noticeable in many areas of dentistry. It allows manufacturing processes related to dental restorations to be carried out more accurately and faster in many aspects. A prerequisite for this success is the highly precise three-dimensional transfer of oral structures. Today, this entire process is referred to as digital dentistry; starting with information acquisition in the form of three-dimensional radiological images and digital impressions, through software-supported planning in all its facets and up to computer-based fabrication of the restoration. In this process, conventional work steps such as molding and model fabrication are replaced by digitalised procedures. This should enable more effective and modern treatment concepts, which ultimately improve clinical care.

The aim of this research area at the Clinic for Dental Prosthetics is to examine individual work steps in order to detect inaccuracies and to further develop the work processes to reduce or eliminate them. The aim is to establish non-contact, optical and three-dimensional measuring methods in digital dentistry that were previously reserved for industrial manufacturing (car industry, aircraft construction).

 

Biography

Mr. Priv.-Doz. Dr. Ragai Edward Matta works as an academic senior councillor and senior physician at the “Zahnklinik 2 – Zahnärztliche Prothetik” of the University Hospital Erlangen. The beginning of his career in dentistry started with studying dentistry at the Friedrich-Alexander-Universität Erlangen-Nürnberg. After completing his studies, he moved to the “Zahnklinik 2 – Zahnärztliche Prothetik” as a research assistant and received his doctorate in 2012, supervised by Prof. Dr. Manfred Wichmann. He was appointed Academic Councillor in 2014 and Scientific Director of the “Zahnklinik 2 – Zahnärztliche Prothetik” in 2015. In 2017, he established the Digital Dentistry Curricula on “Tooth-supported restorations” and on “Implant-supported restorations” as part of the teaching. In 2019, he was appointed Academic Senior Councillor and Senior Physician and received the Venia legendi in the subject of “Dentistry, Oral and Maxillofacial Medicine” in the same year. Lastly, he submitted his habilitation on the topic of “Optical 3D measurement methods in digital dentistry”.
