25 years of guided bone regeneration - the science and biology


The principle of guided bone regeneration (GBR) has been in clinical use for almost three decades. A thorough understanding of the underlying biological mechanisms of GBR is essential in order to optimise treatment modalities and clinical success. Recent findings suggest that membranes used for GBR play a much more active role in the healing event than previously understood. This presentation will discuss the history, evolution and the latest findings with regard to biological events taking place when using resorbable and non-resorbable membranes and how they affect the clinical use and outcome. The presentation will also discuss how modifications of the membrane materials interact with wound healing and how these can be used in the clinical setting. 

Learning Objectives

  • To understand the current biological principles of GBR.
  • To understand how different membrane materials interact with wound healing.
  • To be aware of suitable combinations of bone substitute and membranes with regard to defect types.
  • To understand the clinical steps that need to be addressed for optimal regenerative outcome.


Dr Christer Dahlin is a Professor in Guided Tissue Regeneration and Oral Surgery at Department of Biomaterials, University of Gothenburg, Sweden. He is also a senior consultant in Oral & Maxillofacial Surgery at NÄL Medical Center Hospital, Trollhättan, Sweden. He is a visiting Professor at University of Michigan, Ann Arbor, MI, USA.  He is Vice President and member of the Executive board for the Osteology Foundation. He also acts as a member of editorial boards for several journals in the dental field. Professor Dahlin is considered one of the pioneers in the development of the concept of guided bone regeneration (GBR). He has over thirty years of experience in this field as well as in implant treatment and related research. He is currently involved in both basic research focusing on the biological mechanisms related to GBR as well as clinical trials. He has published numerous articles and textbooks on these topics. He frequently travels worldwide to lecture, conduct research and teach on this and other implant-related topics.
