Damon's philosophy is based on gradual tooth movements generated by weak forces. It aims to help surrounding bone to remodel favorably. This way of thinking justifies expansion as an alternative to extraction. However, it is well established that teeth can be moved according to their myo-functional equilibrium and periodontium condition. The aim of this study is to analyze coronal height on various teeth both before and after treatment with the Damon system. Measures have been carried out on virtual models. Results showing a link between expansion and coronal height which increase by 0.65 mm when both the maxillary and mandibular arches are taken into account.
Key words: Expansion / Damon / Bracket device / Periodontum status / Coronal height
