Main areas of research interests:
Orthodontic treatment of adult patients as well as interdisciplinary treatment, especially in cooperation with oral and maxillofacial surgery, prosthodontics and periodontology.
Basic research on orthodontic tooth movement, interrelation between orthodontics and periodontology, skeletal anchorage. Clinical and experimental studies dealing with modern oral hygiene strategies in patients with different orthodontic therapies.
Oral Health-related Quality of Life in a Randomised Controlled, Multi-Centre Study with Two Different Aligner Staging Protocols
In this randomised controlled, multi-centre study, the effectiveness of two differentiated aligner staging protocols (weekly versus biweekly) was compared with regard to oral health-related quality of life.
Eighty-eight subjects were recruited in four centres (two university hospitals: Düsseldorf and Mainz and two specialist orthodontic practices: Cologne and Berlin) and randomly assigned to either Group A (two-week schedule) or group B (one-week schedule) with results stratified by initial status and sex. In total, 83 subjects (exclusion because of a screening error and five drop-outs) were analysed. All subjects received a set of ClearCorrect® aligners according to the assigned treatment plan. The number of aligners and the sequence of tooth movement were therefore individually adjusted and differed between the subjects.
The data analysis of the six-month follow-up visits is presented here for the first time. The treatment performance of the aligners is correlated with secondary endpoints such as parameters for oral health-related quality of life and subjective patient evaluation (wearing comfort, pain experience, speech impairment).
The aim of this study is to provide evidence-based findings on the optimal staging duration of aligner treatment. The results will help to improve the efficacy and safety of treatment with aligners and ultimately patient outcomes and satisfaction.
