    • Abstract
    • In fixed Class II treatment, achieving desired outcomes while minimizing unwanted side effects requires careful biomechanical considerations. A thorough understanding of potential dental side effects is therefore crucial. This webinar will address key clinical questions: Which dental side effects can be entirely avoided, which can be controlled, which must be accepted, and under which circumstances does a fixed Class II treatment represent a contraindication? Drawing on typical clinical examples and many years of experience with the Herbst appliance, we will explore the specific challenges of managing anchorage and side effects in Class II correction. Scientific evidence will support the clinical insights, enabling participants to critically evaluate treatment strategies and outcomes. By the end of this webinar, postgraduate students will have gained a new perspective on anchorage management in fixed Class II treatment. They will understand how to anticipate, interpret, and manage dental side effects in an evidence-based manner.

    • Learning outcomes
    • Learning outcomes for this webinar are:

      • 1. To understand the forces and counterforces involved in Herbst appliance therapy.
      2. To anticipate typical side effects across different spatial dimensions.
      3. To classify risks and consequences of dental side effects on an evidence-based foundation.


    • Short Speaker Bio
    • Professor Katharina Klaus is Assistant Professor in the Department of Orthodontics at Justus Liebig University Giessen (JLU), Germany. She is active in under- and postgraduate teaching as well as bridging research findings to clinical practice in orthodontics. Her academic portfolio spans publications investigating treatment stability, appliance effects, and methodological advances in orthodontic imaging and retention. She conducts her research within the lab of Prof. Sabine Ruf and contributes to innovations in clinical orthodontics. Dr. Klaus has authored and co-authored studies in high-impact journals on topics such as unwanted tooth movements under bonded retainers, the long-term behavior of white spot lesions after orthodontic treatment, and the accuracy of digital impressions especially in multibracket appliance patients and periodontically compromised situations. Her recent projects include a 3D analysis of CAD/CAM-fabricated retainer accuracy and investigations into the posterior airway changes during Herbst plus multibracket treatment.
