Benedict Wilmes

Dr. Wilmes did a postgraduate training in oral surgery at the Department of Maxillofacial Surgery at University of Muenster, Germany. Subsequently, he received a postgraduate degree in orthodontics and dentofacial orthopedics at the University of the Duesseldorf, Germany. In 2013 he became Professor at the Department of Orthodontics at the University of Duesseldorf. Dr. Wilmes is author of more than 200 articles and textbook chapters. He is reviewer of numerous journals and has held more than 400 lectures and courses in 70 different countries all over the world. His primary interest is in the area of non-compliant and invisible orthodontic treatment strategies (TADs and Aligners). Dr. Wilmes has invented numerous treatment strategies and appliances in orthodontics (e.g. MARPE/Hybrid Hyrax, Mesialslider, Beneslider, “Mousetrap” molar intrusion, Benefit mini-implant, Beneplate). He was awarded the First Prize of the German Orthodontic Society in 2007, the First Prize of the European Orthodontic Society in 2009, the First Prize of the German Society for Lingual Orthodontics in 2018, and the Award of the International Academy of Clear Aligners in 2019. Dr. Wilmes is an Associate Editor of the Journal of the Asian Pacific Orthodontic Society and an Active Member of the Angle Society (Eastern Component).

The Update on TADs Using CAD-CAM Technologies

In recent years, the orthodontic specialty continues to make significant advances with the development and incorporation of various digital technologies. The objective of this lecture is to illustrate the full digital process for the use of mini-implants and miniplates including custom fabrication of CAD-CAM insertion guides and 3D printing of metallic mini-implant supported appliances. For the digital workflow, several software platforms are available from virtual mini-implant insertion to the design of the CAD-CAM appliances. Digital Benesliders can be designed using virtual abutments, rails, connectors, sliding tubes and shells. To complete the digital workflow, insertion guides are designed to contain the information of mini-implant insertion site, angulation and insertion depths. The final parts (Slider framework, molar shells, sliding tube, insertion guide) are exported and materialised using modern 3D-printing techniques. For production of the metallic components selective laser melting is used. The insertion guide is printed using stereolithography and biocompatible resin. These CAD-CAM procedures can be used not just applied for palatal sliders, but also for numerous variations of maxillary anchorage devices, e.g. maxillary expanders, such as the Hybrid Hyrax or the Quadexpander.

Overcoming Aligner Limitations by Using Mini-Implant Borne Sliders and Expanders

An increasing number of patients seek orthodontic treatment with aligner therapy. Bodily tooth movement with aligner therapy is challenging when relying on aligners alone. Whilst there are limited reports of successful bodily molar movements of up to 1-2 mm in the liter-ature, a very long treatment time, many refinements and a high level of patient compliance are expected. Moreover, the potential side effects of intermaxillary elastics must be consid-ered in terms of shift of the anchorage teeth; this might be a severe problem especially in unilateral elastics applications with the potential for development of a midline shift, arch rotation and a jaw discrepancy, and transverse occlusal canting. To avoid this anchorage loss and the high demand on elastic wear, orthodontic mini-implants may be used. Current-ly, the alveolar process and the IZC region are still the most preferred insertion sites for mini-implants. However, due to a failure rate and the risk of root damage, insertion in these areas is far from satisfactory. Additionally, a bodily tooth movement is not granted. On the other hand, the anterior palate provides much better conditions for the insertion and stabil-ity of skeletal anchorage devices, as the amount and quality of the available bone is far su-perior. In this course, the combination of mini-implant-borne appliances and aligners is pre-sented to achieve more predictable and faster results in aligner therapy.
