The orthodontic clear retainer, a transparent shell worn at night, is appealing due to its aesthetics but presents challenges: daily discipline, frequent loss, rapid wear (18\u201336 months), high recurring cost (\u20ac600\u2013\u20ac1,200 over 10 years), and a significant risk of relapse (70% if forgotten). It should not be confused with invisible aligners<\/strong>: unlike them, its purpose is not to move teeth, but to preserve the results achieved<\/strong> after treatment. While not reimbursed, it offers several advantages but can promote plaque and cavities if oral hygiene is imperfect. <\/p>\n\n

Conversely, the fixed retainer made of PEEK eZtain<\/strong> is placed only once, is invisible because it’s bonded behind the teeth, is biocompatible, requires no patient effort, is virtually unbreakable (\u2265 5 years), and provides 24\/7 protection with no risk of being forgotten. For long-term stability, it is currently the most reliable option. <\/p>\n\n

Introduction<\/strong><\/h1>\n\n

At the end of orthodontic treatment, the stabilization phase<\/strong> occurs. After orthodontic treatment has allowed for repositioning the teeth correctly<\/g>, the stabilization phase solidifies this new position through the placement of a clear retainer or a retention wire<\/g>. More than the treatment itself, it is this stabilization phase<\/g> that determines the longevity of the result. Even after treatment, the periodontal ligaments (which connect the teeth to the bone) retain memory of their former position; without a retention device, teeth will shift again within a few weeks. <\/p>\n\n

A first stabilization phase of two and a half years is carried out by placing a mandatory retention wire<\/a>. After this, wearing an orthodontic clear retainer becomes possible<\/strong>, which many patients then imagine as a solution to improve their quality of life. However, as we will see in this report, this is not always true. <\/p>\n\n

This article thus explains in detail the actual functioning of the clear retainer, its cumulative cost, its limitations, and its potential alternatives.<\/p>\n\n
