Biography

Prof. Dr. Christoph Bourauel

Professor Dr. Bourauel is physicist and affiliated with the Dental Clinic at the University of Bonn
since 1987. After heading the Orthodontic Biomechanics Laboratory for more than 15 years, he
took over the Endowed Chair of Oral Technology at the University of Bonn in October 2006. The
main focus of his scientific work lies in the fields of dental biomechanics and materials science,
with a focus placed on orthodontic superelastic nickel titanium alloys, friction in arch guided tooth
movement, and theoretical modelling of orthodontic tooth movement as well as bone/implant
interactions. Dr. Bourauel has published more than 250 papers in national and international
journals in orthodontics, biomechanics, biomedical engineering, and materials science and has
around 600 interdisciplinary oral and poster presentations on Congresses and Symposia. Together
with various co-workers he received several awards, beside them the Best Paper of the Year Award
of the German Association of Orthodontists (DGKFO) in 1990 and 2014, the Helen and B.S.
Dewel Award of the AAO in 1992, the Implant Dentistry Award of the German Association of
Dental Implantology (DGZI) in 2007, the Distinguished Teacher Award of the European
Orthodontic Society (EOS) in 2007, and the International Clear Aligner Research Award in 2011.

Abstract Synopsis

”BIOMECHANICAL SIMULATION OF IMPLANT SELECTION AND POSITIONING,
PROBLEMS AND PROSPECTS ”

Prof. Dr. Christoph Bourauel

ABSTRACT

Over the past decades dental implants became an accepted therapy option with reasonably high
success rates and patient satisfaction. Nevertheless, depending on the cited publication, a
percentage of up to 15 % of inserted implants fail. Causes for failure are various and include
inflammation, improper insertion and bone resorption due to biomechanical overloading.
Concentrating on the biomechanical aspects of the problem, a detailed mechanical analysis of the
loading situation during biting, chewing, and grinding is required.
In this presentation the steps necessary to establish a full patient-individualized biomechanical
analysis of the intra-oral loading situation are described. Topics cover the basics of patient-specific
numerical (finite element) modelling of teeth, hard and soft tissues, mesh generation and analysis of
mesh quality, material properties of all structures involved, and intra-oral loading due to muscular
activity.
Aid of several examples, interpretation of the results is presented. The examples cover analysis of
implant loading in the “All-on-Four” concept, immediate versus delayed loading or systematic
analysis of implant geometries in the course of the development of a new implant series.
