Dr Andersson completed undergraduate and research training at Karolinska Institute in Stockholm, Sweden, and then became a Specialist in Oral and Maxillofacial Surgery (OMFS) in 1981. He defended his doctoral thesis on experimental and clinical studies on replantation of teeth and was appointed Docent at Karolinska Institute in 1990. In the 1990s he chaired a national specialist resident training program in OMFS and belonging to the first-generation implant surgeons he directed international implant training programs for surgeons from all continents of the world. During the period 2002-2017, he was Professor in OMFS at Kuwait University and Chairman of Department of Surgical Sciences, leading education and research and developed a university hospital clinic. Since 2018, he is a semi-retired and senior professor in Oral and Maxillofacial Surgery at Malmö University, Sweden. He is also a board member of the Dental Trauma Guide team in Copenhagen. His main areas of clinical and research interests are trauma, orthognathic, and implant surgery and he has more than 200 lectures, presentations, and publications of which more than 100 original research articles in international Medline indexed scientific journals. He has lectured in 40 countries on all continents of the world and has been a supervisor for PhD and Master students. He is editor of five textbooks and chapter author in several textbooks in the fields of Trauma and OMFS. He was Editor-in-Chief of the Medline indexed scientific journal, Dental Traumatology from 2007-2015 and President of the International Association of Dental Traumatology 2011-2014.


The most serious dental injury is avulsion (exarticulation) of permanent teeth. This injury is most often seen in young growing patients, which presents special problems when it comes to treatment. The most important phase for the prognosis is the emergency management. An avulsed tooth can be replanted and successfully heal if properly managed immediately after the injury. Injuries to the periodontal membrane and the pulp will sometimes decrease the possibility for a successful healing of the replanted tooth, but replantation should always in general be carried out, because today we understand and have learned how to manage complications. Clinicians must understand the principles of tissue injury and healing of tissues after replantation to be able to early diagnose and correctly manage potential later complications such as root resorption, ankylosis and infraposition, which is especially important in growing children. The lecture will present principles of clinical management, tissue healing, diagnosis and treatment of potential complications based on evidence from scientific literature. Recent research will be presented.
