Prevention, therapy and innovative treatment concepts

Orthodontics is the specialised field of dentistry that covers the detection, treatment and prevention of misaligned teeth and jaw anomalies. The prevention of functional disorders and their treatment play a decisive role in this.

The interweaving of research projects with patient care, further training and teaching enables a modern and innovative therapy concept. The treatment spectrum ranges from orthodontic prevention to combined oral surgery and orthodontic therapy for adults, including patients with physical and mental disabilities.

The aim of the therapy is to achieve a balanced, functionally stable system by harmonising the position of the teeth and jaws as well as facial soft tissues. Orthodontic treatment can make an important contribution to maintaining the health of the masticatory system in the long term.

Research

The Department of Orthodontics pursues several research specialisations, which we carry out together with cooperation partners within and outside the university.

Interdisciplinary collaboration takes place in clinical research, including with the specialisms of maxillofacial surgery, oral surgery, periodontology and speech therapy.

Research projects

  • Studies on the validity of intraoral scans and alginate impressions
  • Quantitative assessment of palatal bone thickness for the insertion of orthodontic implants using CBCT
  • Investigation of the clinical reproducibility of virtual setups of the Insignia™ system in orthodontic-jaw surgery combination therapy - a prospective clinical study
  • Effectiveness of treatment for positional plagiocephalus using customised head prostheses
  • Incidence and severity of orthodontically induced external apical root resorption
  • Investigation into the material properties of various orthodontic autopolymerising resins in comparison to light-curing resins
  • In vitro investigation of direct luting of brackets - a comparative study of adhesives
  • Long-term fluoride release from different material groups
  • Orthodontic bonding systems
  • Effects of palatal expansion on nasal breathing, soft tissue, tooth position, alveolar process and palate - a prospective comparison between the plastic cap splint and the modified Haas expander Palex (Palatal Expander)
  • Modern methods for palatal expansion - prospective comparative study of the two skeletally anchored GNE appliances Maxillary Skeletal Expander and Hybridhyrax
  • Study on the systematic correlation between the first milk tooth eruption and the eruption of the first permanent tooth

Teaching

Orthodontic training should enable students to recognise and prevent dysgnathia, i.e. malformations of the teeth, jaw and masticatory system. The focus is on diagnosis and diagnostics. The basic principles of the forms of therapy based on this are worked out.

The teaching concept includes interdisciplinary co-operation with dentistry in theory and practice. In particular, we take periodontal aspects into account in pre-prosthetic and pre-surgical treatment measures. We also co-operate with general practitioners to solve complex orthodontic problems.

The focus of orthodontic training:

  • Development and growth of the facial skull and teeth
  • Etiology of malocclusions and jaw anomalies
  • Orthodontic prophylaxis and preventive measures
  • Interdisciplinary treatment concepts
  • Early treatment
  • Initial orthodontic consultation and assessment of findings
  • Evaluation of diagnostic documents
  • Basics of orthodontic treatment planning
  • Legal guidelines for orthodontic treatment
  • Basics of orthodontic therapy using removable and fixed treatment appliances
  • Fabrication of removable orthodontic appliances


In the Orthodontics learning portal, students and training assistants can find orthodontic training and further education content (lectures, seminars, learning videos, scripts).
