Programme Detail

  1. Auditorium, Oslo Spektrum

    Aligner therapy is gaining popularity among both patients and orthodontists, with products continually advancing. As patient expectations on orthodontic treatments increase, it is essential for us to have a comprehensive understanding of the biomechanics and limitations of this approach, particularly when treating complex malocclusions. This lecture aims to elucidate the fundamental workings of aligners and how this knowledge can be implemented to achieve excellent orthodontic outcomes in challenging cases. The combination of considering patient-centered outcomes with effective biomechanical setups in aligner therapy is the foundation for successful case management, allowing practices to elevate their standard of care.

    Hear 3 high high concise presentations (full presentations from each of the speakers has been recorded in advance and is available here), giving 3 different opinions on this hot topic. The idea is to highlight the good and the not-so-good things about orthodontic aligners and to help clinicians make informed decisions. 

    The speakers will focus on the current state of affairs and will take a look into the future. It will be a lively session with a chance for you to participate with your comments and questions.

    Join us for a provocative session


  15. Auditorium, Oslo Spektrum

    The purpose of this presentation is to fill in the gap between existing literature regarding the treatment of impacted canines and the needs of orthodontists’ in the digital age.  With a thorough review of existing literature, we found that few authors have, in fact, explored the use of clear aligners to treat this type of malocclusion.  We followed Farzin Heravi's clinical protocol suggested in 2016 for conventional orthodontics dividing each treatment into two phases, the first of which is conducted with temporary anchorage devices (TADs) for tooth recovery.  Subsequently, we realized the orthodontic teeth movements with aligners customizing the treatment plan and the biomechanics with ClinCheck® treatment planning software.

    Our observations suggest that a combination of temporary anchorage devices (TADs) and aligners can be an effective therapy for impacted canines.

    Align Technology

  16. Auditorium, Oslo Spektrum

    Severe malocclusions with skeletal elements impose a challenge to the current orthodontic specialty. Simple appliances such as brackets with archwires may not address complicated skeletal defects due to their inadequate impact on bone structures. Orthopedic approaches have proven to be effective solutions to the skeletal anomalies. The specially designed and customized manufactured clear orthopedic appliances, including sagittally guided twin block (S8-SGTB), modified Herbst (S8-SGHB) and a variety of tailored clear appliances, are used to modify the growth patterns of the oral facial bone structures and therefore to correct jaw discrepancies efficiently and effectively. Radiographic evidence in condylar new bone formation generated by mandibular advancement inspires an encouraging impetus to orthopedic modalities. S8-SGTB and S8-SGHB also demonstrate promising efficacy in treating malocclusions concurring with TMD, due to their effects in provoking adaptive remodeling of TMJ condyles in response to mandibular repositioning. This lecture will present an overview on the latest advances in clinical orthodontics evidenced by a wealth of literature review and beautifully finished cases.
