Data selection and extraction are done independently by two reviewers, then validated and gathered after consensus to limit bias. Twelve low to medium evidence level studies meet the inclusion criteria, including two dedicated to jaw impaction surgery. All the studies analyzed short-term dentoskeletal changes, six assessed long-term stability up to 3.5 years for group B and to 4 years for group A. Both groups showed a decrease in anterior facial height and closure of the anterior openbite by mandibular autorotation. The results were stable over the long term for both groups. The orthodontic solution of molar intrusion associated with skeletal anchorage is an alternative to the surgical solution of mild skeletal openbite in adults.

How does this engage orthodontics? Orthodontists are directly concerned by the vertical position of the collars which they must consider. More indirectly, they can have an influence on the gum festoon and in particular on the papillae. The analysis of the literature of the undesirable effects of orthodontics on the periodontium is provided but with limited conclusions which do not constitute scientific evidence. It remains very important to analyze them in order to draw a guide of clinical conduct. The vestibular version and the alveolar expansion present risks of gingival recession that must be taken into account. The presence of the papillae responds to precise anatomical conditions that have to be controlled to avoid disastrous black triangles when aligning the teeth. The shape of the teeth is directly involved in these phenomena. Stripping may be an appropriate therapeutic response to prevent or limit these iatrogenic effects. The approach is first of all diagnostic (identification of the shape of the teeth, analysis of the dento-dental disharmony (DDD), evaluation of the amount of stripping and its consequences on the DDD) and then prognostic in order to establish the treatment plan... The author will illustrate this approach by the teachings of the literature and by clinical illustrations of treated cases. The balance of a smile is based on the respect of shapes, anatomical proportions and the conditions necessary for healthy tissue. It is our role to respect them in the project of establishing harmony. The beauty of the smile reflects the patient's own personality: « Orthodontists are the technicians of the semaphore of the soul », Axel Kahn, Journées de l'Orthodontie, 2007.</p>","PeriodicalId":35927,"journal":{"name":"L'' Orthodontie française","volume":"92 1","pages":"141-157"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38820648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective is not to decide on the superiority of one system over another, but to expose all the possibilities for adapting the digital tool to the orthodontist's method of retention. The benefit of using digital technology is saving time and improving performance, minimizing unnecessary manipulation and improving device precision.
