| Beschreibungen: | Introduction: The aim of this study was the evaluation of treatment outcomes using a mini-implant borne distalization appliance employing direct anchorage – the Beneslider.
Methods: Treatment of 51 patients (mean age 17.8 ± 9.6 years) was investigated retrospectively by means of pre- and post-treatment cephalograms. Patients were divided into three groups: 14 children with unerupted upper second molars (group 1), 23 adolescents with second molar in place (group 2) and 14 adults (group 3). Treatment changes were evaluated and tested statistically for significant differences. Results: Class I molar relationship was achieved in all patients. All mini-implants remained stable during treatment. The mean distalization distance as measured by the displacement of the Trifurcation was 3.6 ± 1.9 mm (range: 1.2 to 8.5 mm depending on treatment needs). Since no significant tipping was found, the type of movement could be characterized as bodily movement. Mean overall distalization speed was 0.6 ± 0.4 mm per month. There were no statistical differences between the groups. In the analysis of skeletal vertical measurements, there were no significant changes of NSL-ML and NL-ML. Conclusions: The Beneslider was found to be an effective appliance that enables bodily distalization in adequate treatment time. Its design provides a high degree of anchorage stability and also prevents bite opening.Introduction: The aim of this study was the evaluation of treatment outcomes using a mini-implant borne distalization appliance employing direct anchorage – the Beneslider.
