Solutions thérapeutiques sans extraction de prémolaires face à une DDM négative : place et limite de la distalisation mandibulaire. Revue de la littérature

Abstract : Purpose: The aim of this literature review was to search and quantify the limits of mandibular molar distalization according to the anatomical characteristics of the patient and the techniques used. This analysis was a way to define the place of this therapeutic tool in the management of arch length discrepancy without extraction of premolars. Material and Method: A literature survey of Cochrane, Pubmed, Scopus was conducted until April 2019. Human studies, randomized clinical trials, prospective and retrospective studies talking about the anatomical limitations and quantitative effects of mandibular molar distalization were included. A single reviewer selected and extracted data. Results: a total of 26 articles were selected. Among the 3 articles analyzing the anatomical limits, the lingual cortex and not the anterior border of the branch was retained as the posterior limit to distalization, the inferior alveolar nerve was also an obstacle to distalization but reported only for 1 clinical case. The amount of distalization was slightly or not affected by the distalization technique used in the remaining 23 articles. The mean value of distalization was 3.4 mm in 9.1 months. The increasing use of bone anchorage these last years has made possible a better control of the parasitic effects generated by other techniques. However, the corono-distal version remained an almost inevitable event. Conclusion: Mandibular molar distalization has its place in the management arch length discrepancy. Its use, combined with transverse expansion, incisor version and stripping, allows to push the limits of treatments without the extraction of premolars.
