    Absolute Anchorage in Orthodontics

    Dr Junji Sugawara is a Director of the Department of Interdisciplinary Dentofacial Therapy at the Sendai Aoba Clinic, Sendai, Japan, and a Visiting Clinical Professor at the Division of Orthodontics, School of Dental Medicine, University of Connecticut, Farmington, USA. He graduated from Tohoku University, Sendai, Japan in 1973 and worked there over 30 years.

    He is an active member of the Edward H. Angle Society (North Atlantic Component) since 2004. His key interests are in the skeletal anchorage system utilizing titanium miniplates as temporary anchorage devices and Sendai surgery first. He has given many lectures on these subjects in the Europe, the United States, South America, Australia, the Middle East and Asia.

    Long-term stability following the surgery first approach in Class III patients

    Surgery first (SF) was developed to address the serious problems associated with conventional surgical orthodontics, including a worsening facial appearance and occlusion during pre-surgical orthodontics, and extended treatment time. In the SF approach, jaw surgery is carried out to resolve skeletal problems as the first step and then the dental problems are corrected orthodontically. In our team, this approach was made possible by the application of the skeletal anchorage system (SAS), which enables predictable three-dimensional movement of the molars to solve complex orthodontic problems immediately after jaw surgery. The efficiency of surgical orthodontics is greatly improved by the SF approach, and it is much more patient friendly. Although there are many advantages in SF, because it is a recent advance in orthodontics, the long-term dentofacial stability following SF has yet to be clarified. In this presentation, the focus will be on stability after SF on the basis of 5-year follow-up cases in Class III.

    Aims: To provide information about the benefits and problems of SF and long-term dentofacial stability following SF on the basis of 5-year follow-up  in Class III patients.

    Objectives: To give contemporary evidence regarding how to predictably achieve treatment goals with the application of SAS biomechanics and maintain dentofacial stability over a long period of time post-operatively.

    Learning outcomes: By attending this presentation, attendees will acquire contemporary knowledge of the advantages of SF and of the importance of SAS biomechanics in post-surgical orthodontic treatment for managing complex orthodontic problems and maintaining long-term stability.
