Sans traitement, le sujet en classe III pr\u00e9sente un torque maxillaire excessif et d\u00e9couvre majoritairement les incisives mandibulaires, signe qui s\u2019accentue avec l\u2019\u00e2ge. L\u2019orthop\u00e9die fonctionnelle permet de restaurer le caract\u00e8re esth\u00e9tique du sourire par protraction maxillaire (parfois provisoirement car 20\u2009% des cas auront quand m\u00eame besoin d\u2019une chirurgie). Selon la s\u00e9v\u00e9rit\u00e9 initiale du cas (\u22124,5\u2009mm d\u2019AoBo constitueraient la valeur seuil), les options sont la compensation ou la correction chirurgicale. Dans les deux cas, le profil est am\u00e9lior\u00e9, mais sans pour autant obtenir une normalisation des valeurs c\u00e9phalom\u00e9triques. Ces derni\u00e8res ann\u00e9es, les publications de cas trait\u00e9s par compensations (souvent par ancrage osseux) se sont multipli\u00e9es avec des indications plus larges, en particulier pour les patients asiatiques pour lesquels la chirurgie de Le Fort I donne des r\u00e9sultats esth\u00e9tiques discutables. L\u2019attention doit alors \u00eatre port\u00e9e sur la bascule du plan d\u2019occlusion, laquelle alt\u00e8re le sourire par la visibilit\u00e9 des incisives mandibulaires. N\u00e9anmoins, la chirurgie permet de g\u00e9rer les cas les plus s\u00e9v\u00e8res avec une proportion d\u2019am\u00e9lioration plus importante.<jats:bold>Objectif<\/jats:bold>\u2009<jats:bold>:<\/jats:bold>L\u2019objectif de cet article est de rechercher, par l\u2019analyse de la litt\u00e9rature, les valeurs limites c\u00e9phalom\u00e9triques pour un sourire acceptable des patients en classe III.<jats:bold>Mat\u00e9riels et m\u00e9thodes<\/jats:bold>\u2009<jats:bold>:<\/jats:bold>Nous avons effectu\u00e9 une recherche sur Pubmed \u00e0 partir de mots cl\u00e9s\u2009:<jats:italic>class III, anterior cross bite, smile, camouflage, orthognathic surgery<\/jats:italic>, puis secondairement \u00e0 partir des r\u00e9f\u00e9rences fournies par les articles trouv\u00e9s et avons analys\u00e9 les donn\u00e9es.<jats:bold>R\u00e9sultats<\/jats:bold>\u2009<jats:bold>:<\/jats:bold>Le protocole ortho-chirurgical associ\u00e9 aux extractions de premi\u00e8res pr\u00e9molaires maxillaires serait le moyen d\u2019obtenir les meilleurs r\u00e9sultats en termes de sourire (<jats:italic>versus<\/jats:italic>la chirurgie sans extractions et<jats:italic>versus<\/jats:italic>les compensations orthodontiques) car c\u2019est, en effet, le seul moyen de r\u00e9tablir une position et un torque normalis\u00e9s des incisives maxillaires, ce qui augmente leur visibilit\u00e9 lors du sourire.<\/jats:p>","DOI":"10.1051\/orthodfr\/2018002","type":"journal-article","created":{"date-parts":[[2018,4,20]],"date-time":"2018-04-20T07:50:10Z","timestamp":1524210610000},"page":"81-91","source":"Crossref","is-referenced-by-count":2,"title":["Le sourire\u2009: un enjeu dans la d\u00e9cision th\u00e9rapeutique des classes III"],"prefix":"10.1684","volume":"89","author":[{"given":"Laure","family":"De Launay","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sarah","family":"Gebeile-Chauty","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"18929","published-online":{"date-parts":[[2018,4,20]]},"reference":[{"issue":"1","key":"R1","doi-asserted-by":"crossref","first-page":"161","DOI":"10.2334\/josnusd.16-0004","volume":"59","author":"Akan","year":"2017","journal-title":"J Oral Sci"},{"issue":"5","key":"R2","doi-asserted-by":"crossref","first-page":"103","DOI":"10.1590\/2176-9451.21.5.103-113.bbo","volume":"21","author":"Almeida","year":"2016","journal-title":"Dental Press J Orthod"},{"key":"R3","doi-asserted-by":"crossref","first-page":"130","DOI":"10.1053\/j.sodo.2007.05.006","volume":"13","author":"Baccetti","year":"2007","journal-title":"Semin Orthod"},{"issue":"2","key":"R4","doi-asserted-by":"crossref","first-page":"184","DOI":"10.1016\/S0889-5406(97)70214-2","volume":"111","author":"Braun","year":"1997","journal-title":"Am J Orthod Dentofacial Orthop"},{"key":"R5","first-page":"139.e1","volume":"137","author":"Burns","year":"2010","journal-title":"Am J Orthod Dentofacial Orthop"},{"key":"R6","doi-asserted-by":"crossref","first-page":"205","DOI":"10.1051\/orthodfr\/2016023","volume":"87","author":"Chaques Asensi","year":"2016","journal-title":"Orthod Fr"},{"key":"R7","first-page":"25","volume":"145","author":"Choi","year":"2014","journal-title":"Am J Orthod Dentofacial Orthop"},{"issue":"3","key":"R8","doi-asserted-by":"crossref","first-page":"109","DOI":"10.1590\/2177-6709.22.3.109-118.bbo","volume":"22","author":"De Arruda","year":"2017","journal-title":"Dental Press J Orthod"},{"issue":"5","key":"R9","doi-asserted-by":"crossref","first-page":"577","DOI":"10.1016\/j.ajodo.2009.10.037","volume":"138","author":"De Clerck","year":"2010","journal-title":"Am J Orthod Dentofacial Orthop"},{"issue":"3","key":"R10","first-page":"241","volume":"48","author":"Gebeile-Chauty","year":"2014","journal-title":"Revue d\u2019ODF"},{"issue":"1","key":"R11","doi-asserted-by":"crossref","first-page":"23","DOI":"10.1051\/orthodfr\/2010035","volume":"82","author":"Gebeile-Chauty","year":"2011","journal-title":"Orthod Fr"},{"issue":"3","key":"R12","first-page":"235","volume":"88","author":"Gebeile-Chauty","year":"2017","journal-title":"Une \u00e9valuation sur 258 cas par l\u2019IOTN.
