Treatment options in orthodontics have been expanded by skeletal anchorage via mini-implants over the last few years. Sufficient primary stability is imperative to minimize implant loss rate. The aim of this study was to quantitatively analyze the factors influencing primary stability: bone quality, implant-design, diameter, and depth of pilot drilling.(More)
Skeletal anchorage with mini-implants has greatly broadened the treatment possibilities in orthodontics over the last few years. To reduce implant failure rates, it is advisable to obtain adequate primary stability. The aim of this study was to quantitatively analyze the impact of implant design and dimension on primary stability. Forty-two porcine iliac(More)
When treating pronounced dentoalveolar compensation of a skeletal Class III malocclusion, preoperative decompensation frequently requires the extraction of maxillary lateral teeth and retraction of the incisors. In this context, maximum anchorage of the maxillary molars is frequently necessary to attain the significant increase in negative overjet that is(More)
The use of mini-implants for skeletal anchorage has greatly broadened the therapeutic spectrum in orthodontics over the last few years. The alveolar ridge is the most frequent insertion site, which however is associated with tooth injury, a risk not to be underestimated. The objective of this study was to examine the quantitative parameters of pre-drilling(More)
In the course of a clinical pilot study we tested the vertical periodontal ligament (V-PDL) distraction as a means of aligning ankylosed upper canines. The objective of this study was to analyze the appropriateness und effectiveness of this method. The ankylosed upper canines of five female patients aged between 16 und 19 years were surgically exposed,(More)
Air-polishing devices (APDs) are used to clean and polish tooth surfaces. The objective of this study was to examine the effects of exposing orthodontic wires and brackets to different types of powder when using an APD. Three different wire materials (steel, TMA, Ni-Ti) were polished using an APD (Air-Flow® S1), Clinpro™ Prophy and Air-Flow®. The exposure(More)
