Dr. Marcus Seiler Msc Msc

completed his studies in dentistry and medicine in 1991. After a year abroad at New York University and further occupational activities, he set up his own practice in 1998, now with two clinics in Filderstadt and Kirchheim.

The interest in his field led to further postgraduate education (2005-2007 the "Master of Science in Oral Implantology" and in 2016-2017 a Master of Science in "Periodontology"), which were successfully completed.

Influenced by his clinical activity, he had developed a new technology for the regeneration of bone defects in 2006-2008. This led him to found ReOss® GmbH in Filderstadt in 2009. Subsequently, the Yxoss CBR® technology was developed and multiple international patents were filed to enable commercial use.

Marcus Seiler has been the CEO of ReOss GmbH since 2009 and also acts as Medical Advisor.
