BJORN LUDWIG, D.M.D., M.S.D. Scientific Coordinator and Assistant Professor, University of Homburg/Saar, Department of Orthodontics. Dr. Ludwig’s research is focused on cortical anchorage with mini-screws/mini-plates and their further clinical developments. He is the editor-in-chief of the Quintessence journal, KIEFERORTHOPÄDIE and the co-editor of the Journal of Clinical Orthodontics and Journal of Orthodontic Science.
GEORGIOS KANAVAKIS, D.D.S., M.S. Assistant Professor in the Department of Orthodontics and Dentofacial Orthopedics at Tufts University and Diplomate of the American Board of Orthodontics. Dr. Kanavakis received a postgraduate certificate degree in Orofacial Pain and Temporomandibular disorders. His primary clinical focus is on the use of orthodontic mini-implants for adult orthodontic treatment, skeletal maxillary expansion, as well as distal and mesial molar translation.
Day 1: Lecture
The course will focus on the success rate of mini-implants, palatal implants and miniplates and the biomechanics of the connected orthodontic appliance. It will further provide both the scientific and clinical perspectives on how mini-screws can become a safe and reliable standard device. The course will give a detailed explanation of the clinical use of palatal mini-implants and various miniplates in the mandible. It will also focus on the biomechanics of well working and thought indications.
- Overview of the up-to-date literature
- Current developments of screw design
- Appliance designs
- Main indications
- Placement techniques
- Risk factors during placements and orthodontic treatments
Day 2: Palatal Miniscrews – Insertion and Biomechanics
Day 2 of this two-day course will consist of a hands-on workshop on TAD preparation and placement.
Currently, the alveolar process is still the most preferred insertion site. However, due to the varying bone quality and the risk of root contact, the survival rate of implants inserted in the alveolar ridge, especially interradicular, needs to be improved. Other regions such as the anterior palate provide much better conditions for mini-implant insertion since the amount and quality of the available bone is far superior. Implants with different types of abutments and connectors allow the construction of versatile and cost efficient appliances for a large variety of orthopaedic and orthodontic applications. TADS in the anterior palate eliminate the risk of root injury and take the implants out of the path of tooth movements.
This Hands-on course will involve:
- Insertion of the palatal TADs (identifying the optimal insertion site, anaesthesia and placement of the TADs)
- Transfer of the intraoral situation to a plaster model (adapting transfer caps to the palatal TADs, taking impressions, use of the laboratory analogues)
- Designing the palatal bone born appliance on the plaster model
The workshop will consist of 3 work stations in small groups:
- Anaesthesia and Insertion of the palatal TADS with different techniques/aspects
- Adapting transfer caps, taking impressions and creating a working model
- Building 3-4 different appliances on different typodonts (mesial- and distal slider, bone-born RME and a molar-intrusion appliance)
- TADS, appliances, working material and typodonts
- Printout of all relevant working steps
- USB-driver with the workshop instruction movies and all slides presented in the workshop
Pliers to bend and cut wires up to a diameter of 0.36 inch
- Understand the process of TAD insertion
- Understand the use of anaesthesia for TAD insertion
- Be able to take impressions and create working models
