Therefore, it is more a matter of a positioning defect of the jaws, the lower one being rejected backwards.<\/p>\n\n\n\n<p>In the treatment of front teeth or <strong>retrognathia<\/strong>, 2 situations are proposed (depending on the degree of severity of the shift, the age of the patient, the response to treatment&#8230;):<\/p>\n\n\n\n<ul><li>Orthodontic treatment alone (in 1 or 2 steps);<\/li><li>Orthodontic-surgical protocol (combination of orthodontic and surgical treatments)<\/li><\/ul>\n\n\n\n<h3>Retrognathia in children<\/h3>\n\n\n\n<p>It is quite possible to <strong>treat the upper front teeth as early as childhood<\/strong> (between 6 and 9 years old).

In recent years, new transparent aligners have appeared on the market, attracting thousands of patients with their <strong>discreet<\/strong> appearance.<\/p>\n\n\n\n<p>Aestheticism and efficiency. Custom-made <strong>clear aligners<\/strong> put pressure on your advanced upper teeth to restore them to a more natural position. Orthodontic work is done without anyone noticing.<\/p>\n\n\n\n<p>Among the brands that stand out, we particularly appreciate <strong>the German company Dr Smile<\/strong> which manages to combine quality and very competitive prices.  <\/p>\n\n\n\n<p>Very fashionable, the method is also very popular in <strong>France<\/strong>.

It can be recognized by the presence of a more or less important shift between the upper and lower teeth, with generally the upper teeth projected forward.<\/p>\n\n\n\n<p>Forward teeth are usually associated or related to a positioning disorder of the lower jaw <strong>called<\/strong> <strong>retrognathia<\/strong> <strong>or retromandibulia<\/strong>.<\/p>\n\n\n\n<p>Treatment of front teeth and\/or retrognathia involves <strong>orthodontics<\/strong> or <strong>maxillofacial surgery<\/strong>. The combination of the two interventions is often recommended.<\/p>\n\n\n\n<p>The results of the treatment are, in most cases, <strong>very satisfactory<\/strong>, even <strong>spectacular<\/strong>. The harmony of the face and the smile are clearly improved. In addition, all functional disorders related to retrognathia are effectively corrected.<\/p>\n\n\n\n<p><strong> Prevention is essential <\/strong>in this type of dental malposition. Therefore, parents must be attentive to their children and watch out for bad habits that could harm their teeth or jaws.<\/p>\n\n\n\n<p>If your child shows signs of retrognathia or tooth malposition, don't hesitate to take him or her to a specialist as soon as possible. Indeed,<strong> early management offers better chances of recovery without resorting to invasive treatments<\/strong>.<\/p>\n\n\n\n<p>Don't forget that dental malposition increases the risk of pathologies (caries, tooth loosening, gingivitis, periodontitis&#8230;).<\/p>\n\n\n\n<h2><span class=\"ez-toc-section\" id=\"FAQ\"><\/span>FAQ<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3>How to treat retrognathia?<\/h3>\n\n\n\n<p>This condition is treated with braces and\/or surgery.
