Stations of a scientists life

• Born in 1957, after certification as dentist in 1992 and junior doctor time in the Clinic and Department of Oral and Maxilla-Facial Surgery
at the University of Heidelberg, Dr Duddeck worked for several years as Divisional Director and Head of Program in a specialist medical
publisher.
• 1999 - 2006 Founder and managing director of a leading training and consulting company in the dental industry. Practice coach and speaker
focusing on communication and implantology, and author of numerous text books and articles.
• Since 2007 implantologist & researcher at the Interdisciplinary Department of Oral Surgery and Implantology, and the Department of Oral and
Maxilla-Facial Plastic surgery, University of Cologne, private practice Univ. Prof. Dr. Dr. Zoeller.
Research projects about peri-implantitis and numerous SEM analyses of dental implants
• 2008 to 2012 Study Coordinator and Head of Dentistry Department in the Deanery of the University of Cologne and Project Manager of the
special programme “Social and Communication Competence in Dentistry”. In this project Dr Duddeck has integrated the training of professional
communication skills successfully into the dental curriculum at the University of Cologne.
• 2014 Co-founder & program director of the European Academy of Dental Implantology EADI (www.eadi.eu). The EADI is managing courses in
cooperation with well known universities like the Charité, Berlin. The Certified European Diploma in Implantology is a comprehensive course
with 16 evidence-based, practice-related, hands-on patient treatment accompanied modules in oral implantology. The course will take place in
different locations all over Europe like London, Berlin and Rome (2015) as well as Barcelona, Athens, Budapest, Vienna and more (2016).
Therefore this program fosters not only postgraduate learning and understanding of the host country, but also a sense of community among
colleagues from all over Europe.
• 2014 Founder of the Medical Materials Research Institute, Berlin, specialized in implant material analyses (SEM, EDX, XPS, ISO14801 etc.).
In 2015 Dr.Duddeck realized one of the largest research projects regarding the quality of dental implants. In cooperation with the University
of Cologne and European Association of Dental Implantologists (BDIZ EDI) he analyzed more than 120 different implants.
• Numerous conference presentations, workshops and seminars about implantology and material science for dental companies and for associations in
Germany (DGI, DGOI, DGZI, DGÄZ, BDIZ EDI) as well as in Europe (OSIS/Poland, SEI/Spain, SPCO/Portugal, ADI/UK, BAIRD/UK, Dental Chamber/Croatia
etc.) and Middle East (JUST Jordan University of Science and Technology; BAIRD course in Bahrain).

SEM analysis of osseointegrated phosphorous rich implants after 52 weeks in sheep pelvis

Thema

Aim

The surface of dental implants determines the initial phases of the biological response and affects its ability to integrate into the surrounding tissue. Covalently binding a monolayer of phosphorous rich molecules (SurfLink) (Fig. 1) to well established surface modifications (sandblasting, acid-etching) offers new dimensions of osseointegration(1). The aim of this study is to present the surface analysis of SurfLink implants using Scanning Electron Microscopy (SEM) and elemental analysis (EDX).

Material and Methods

Machined and roughened dental implants with either SurfLink treatment or no treatment (control) were placed in the pelvis of 24 sheep(2). Selected implants, retrieved after 52 weeks healing (Fig. 2 and 3), previously used for removal torque testing, were analyzed by SEM and EDX (Phenom ProX SEM, high-sensitivity backscattered electron detector for topographical mode and thermoelectrically cooled Silicon Drift Detector for EDX).

Results

SurfLink implants showed increased bone coverage on the machined and roughened surfaces compared to control implants. The presence of mineralized fibrous structures was evidenced by significant Ca and P peaks detected by EDX, with bone cells on the SurfLink implant surface (Fig. 4-6). The machined control implant showed a nearly bare titanium surface (Fig. 7-9). Fracture lines after torque testing occurred at the bone-implant interface in the control group (Fig. 13-15), while the SurfLink implants showed a fracture line within the bone (Fig. 10-12), indicating the absence of the typical proteoglycan layer.

Summary:

SEM images of SurfLink implants showed fractures within the bone and not at the bone-implant interface. This suggests a significant increase in bone adhesion on SurfLink surfaces (Fig. 16). Clinically this results in improved implant stability especially in the early phases of osseointegration.
