Curriculum Vitae – Dick Barendregt

Dick Barendregt finished dental school in 1988 at the University of Groningen. He worked as
dentist in the Royal Dutch Navy and several private practices for a period of 5 years.
In 1991 he started his Master of Science training in periodontology at the University of
Amsterdam. After finishing his training in 1994 he worked as periodontist in 2 referral clinics
restricted to periodontology.
In 1996 he founded his own clinic in Rotterdam. In his clinic he works as a specialist in
periodontology and implantology. The last 20 years the emphasis in patient treatment has been
on the interdisciplinary planning (Proclin Rotterdam) together with endodontists, orthodontists,
restorative dentists, dental technicians and fellow periodontists.
Dick Barendregt received on November 4th 2009 his PhD degree on his thesis “Probing around
teeth” and was appointed on July 1st 2019 as Adjunct Professor at the Department
Periodontology, Adams School of Dentistry at the University of North Carolina. He is author and

Abstract

Lecture: Autotransplantation – An interdisciplinary option for predictably treating complex trauma cases

In 1990, Professor Jens Andreasen published his favorable outcomes of 370 transplanted premolars, highlighting the critical role of surgical precision. Motivated by the limitations of dental implants – particularly their ankylotic nature – Proclin Rotterdam adopted Andreasen’s principles in pursuit of a more biological and patient-centered solution.
With over 5,500 registered autotransplants to date, this approach has proven to offer long-term success without the drawbacks of implants, particularly in orthodontic cases involving agenesis, dental trauma, and impacted teeth. The importance of close interdisciplinary collaboration – between orthodontist, endodontist, periodontist, and restorative dentist – has become a cornerstone of treatment success.
This presentation will outline clinical protocols and technical considerations, including 3D planning for surgery and restorative follow-up. It will also highlight the regenerative potential of the periodontal ligament and present long-term outcomes, supported by recent publications from Proclin Rotterdam (2023-2024). Finally, common complications in the orthodontic, endodontic, periodontal, and restorative phases will be addressed.

Learning objectives:

define and provide clinical examples and protocol showing each dental provider’s role in autotransplantation
define tooth autotransplantation
recommend when tooth autotransplantation should be considered in patient treatment
follow the appropriate protocol and timing for tooth autotransplantation
