Available Sessions

  • Alveolar Preservation in a Growing Child after Dental Trauma

    The most challenging sequel to dental trauma is loss of permanent anterior tooth in a growing child. When a root is extracted there in these patients there is a high risk of total collapse of the facial cortical bone plate as well as arrested vertical growth of the alveolus, making an implant placement difficult both because of esthetics and the need for a complicated graft surgery. Recently it has been suggested that to preserved the bone and thereby allow the alveolus to continue growth it is better to leave the damaged, resorbing and/or ankylosed root in place rather than extracting it.

    In the first part of this lecture the most common reason for this premature loss will be presented; how those can be diagnosed clinically and radiographically and what if anything can be done to prevent the loss of the tooth. In the second part of the lecture treatment options like intentional reimplantation, root submergence and decoronation will be discussed in some details and indication for each presented.

    Two to four hours.

  • Diagnosis & Treatment of Traumatic Injuries

    All dental injuries occur when least expected. There is no time to consult textbooks because the time between the appropriate emergency treatment can differentiate between saving or loosing the injured tooth. The first part of the lecture will be supported with actual cases, and a detailed description of diagnostic procedures that are needed to be able to investigate and document traumatic injuries. The second part will focus on new treatment modalities of dental injuries, both in the emergency phase as well as long term.

    Two hour to one full-day lecture.
