Thérapeutique par aligneurs et gestion de la supraclusion : revue systématique

Abstract : The development of the clear aligner therapy for a couple of decades, especially with Invisalign®, made this technique as an alternative to fixed orthodontic treatments. We chose to confront this technique to a frequent disocclusion, and sometimes hard to cure : the deepbite. Considering scientific literature, the objective of this systematic review was to evaluate the efficience, the accuracy and the stability of the deepbite treatment with aligners. We carried out an electronic research throughout the following databases : Pubmed, Scopus, Google Scholar and Cochrane Library. Research were also made in scientific journals. 35 articles were selected. To a certain extent, we noted heterogeneous results and it is still difficult to extract clinical recommandations that would be clear and consensual. More clinical trials are necessary to assess the current aligner therapy towards deepbite. However it seems aligners are able to cure slight to moderate deepbite in quite a predictable way, especially if a buccolingual incisal inclinaison is authorised. In contrast, if the deepbite is severe for a patient excluding growth, and if an important incisive buccolingual inclinaison cannot be realized, accessories such as mini-screws are quickly recommended in order to realise a better anterior intrusion. Fixed appliances are still more efficient and more stable in complex cases of deepbite. An accurate diagnosis, a specific biomechanic knowledge of aligner appliances and their limits, and the optimisation of the dynamic virtual set-up are the necessary conditions to achieve a matching result with the initial objectives of treatment.
