You will discover its principle, how it is performed during a consultation, its precise contribution to the design of appliances, and why it has become essential in orthodontic practices.

The practitioner captures the geometry of the teeth and gums with a camera, and the digital file completely replaces the old plaster models.<\/p>\n<div class=\"iaba-def\" id=\"definition-empreinte-numerique\"><dfn>Digital fingerprint<\/dfn> Three-dimensional modeling of the dentition performed by a <abbr title=\"Three-dimensional intraoral scanner\">3D intraoral scanner<\/abbr>, without paste or plaster, which instantly produces a usable file for the diagnosis and manufacture of orthodontic appliances.<\/div>\n<p>In practice, the orthodontist holds a small, thin-tipped camera in their hand. They move it over the occlusal, buccal, and lingual surfaces of the teeth, while the software reconstructs a 3D model in real time, displayed on the screen. No material is injected into the mouth, no impression trays need to be bitten into, and there is no waiting for the impression to set.<\/p>\n<div class=\"iaba-compare\">\n<div class=\"iaba-compare-before\">\n<h4>Before: alginate imprint<\/h4>\n<ul>\n<li>Cold dough placed on a mold holder<\/li>\n<li>Wait 2 to 3 minutes motionless, mouth open<\/li>\n<li>The gag reflex is common in adults.<\/li>\n<li>Physical molding to be cast in plaster in the laboratory<\/li>\n<li>Bulky storage, risk of deformation<\/li>\n<\/ul>\n<\/div>\n<div class=\"iaba-compare-after\">\n<h4>Next: 3D digital footprint<\/h4>\n<ul>\n<li>Intraoral scanner the size of an electric toothbrush<\/li>\n<li>Progressive capture, free breathing<\/li>\n<li>No prolonged contact with the palate, nausea avoided.<\/li>\n<li>STL or PLY file transmitted electronically<\/li>\n<li>Long-term archiving, unlimited duplication<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<h3 id=\"section-1-1\">Reliability documented by scientific literature<\/h3>\n<p><strong>The accuracy of modern intraoral scanners is now comparable to, or even superior to, that of conventional impressions for orthodontics.<\/strong> An in vivo study published on <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC6981254\/\" rel=\"noopener\" target=\"_blank\">PubMed Central (PMC6981254)<\/a> evaluates the accuracy and precision of intraoral scanners on the complete maxillary arch, demonstrating their reliability for everyday clinical use, including on the complete arches required in orthodontics.<\/p>\n<div class=\"iaba-callout\" data-variant=\"info\">\n<p><strong>Micrometer precision:<\/strong> Current intraoral scanners achieve an accuracy of around 20 to 50 micrometers over a complete arch, a level of detail sufficient to manufacture custom-made aligners and lingual brackets.<\/p>\n<\/div>\n<h3 id=\"section-1-2\">A digital file that can be used immediately<\/h3>\n<p>Unlike physical molding, which must be poured, shaped, and then shipped, the 3D file is transmitted to the laboratory or simulation software in just a few clicks. This digitalization accelerates planning, reduces manufacturing times, and allows for secure sharing between referring practitioners.<\/p>\n<h2 id=\"section-2\">How is the optical impression taken during a consultation?<\/h2>\n<p><strong>The optical impression takes place in 3 to 5 minutes per arch, without pain or injection, comfortably seated in the chair.<\/strong> The patient remains seated, breathes freely and can follow the live modeling on the office screen.<\/p>\n<ol class=\"iaba-steps\">\n<li class=\"iaba-step\">\n<h3>Mouth preparation<\/h3>\n<p>The dental surfaces are gently dried to ensure the camera captures images without unwanted reflections. No products are injected: neither powder, as with most modern scanners, nor paste.<\/p>\n<\/li>\n<li class=\"iaba-step\">\n<h3>Optical scan of the first arch<\/h3>\n<p>The practitioner moves the camera along the upper arch following a defined path (occlusal surface, then vestibular, then lingual). The software reconstructs the 3D model displayed on the screen in real time.<\/p>\n<\/li>\n<li class=\"iaba-step\">\n<h3>Scanning of the second arch and occlusion<\/h3>\n<p>The same procedure is used for the lower arch. The patient then closes their teeth for a recording of the occlusion (how the jaws fit together), captured in a few seconds.<\/p>\n<\/li>\n<li class=\"iaba-step\">\n<h3>File validation and transfer<\/h3>\n<p>The 3D model is checked on the screen, missing areas are completed by targeted scanning, then the file is validated and sent to the planning software or the laboratory.<\/p>\n<\/li>\n<\/ol>\n<div class=\"iaba-callout\" data-variant=\"tip\">\n<p><strong>Good to know:<\/strong> No anesthesia is required. Patients with old braces, bridges, or removable dentures can also benefit from a digital impression without any special adaptation.<\/p>\n<\/div>\n<h3 id=\"section-2-1\">Significantly improved comfort for sensitive patients<\/h3>\n<p>The elimination of the impression tray in the mouth radically changes the experience of the consultation. People with a strong gag reflex, those with a sensitive palate, or those who have difficulty breathing through their nose no longer have to dread this step. Claustrophobic or anxious patients also appreciate being able to see their mouth gradually take shape on the screen, thus demystifying the procedure.<\/p>\n<blockquote class=\"iaba-quote\">\n<p>\u00ab&quot;In daily practice, we observe that adults who were apprehensive about traditional impressions readily accept scanning. Many are even surprised by the speed of the procedure and the accuracy of the result, which is immediately visible on the screen.&quot;\u00bb<\/p>\n<footer><cite>Nicolas Barri\u00e8re, Orthodontist, Qualified Specialist in Dentofacial Orthopedics, founder of the practice<\/cite><\/footer>\n<\/blockquote>\n<h2 id=\"section-3\">How does this 3D technology optimize treatments for adults?<\/h2>\n<p><strong>The digital impression serves as the foundation for the custom design of clear aligners and lingual braces: without it, there is no virtual simulation of the treatment.<\/strong> The 3D file directly feeds into the planning software which draws each planned dental movement, step by step.<\/p>\n<p>For an adult seeking a discreet solution, the choice between <a href=\"https:\/\/nicolasbarriere.fr\/en\/blog\/discreet-orthodontics-in-adults-lingual-braces-and-clear-aligners-two-techniques-with-different-indications\/\">discreet orthodontics (lingual braces or clear aligners)<\/a> This approach is based on a thorough clinical analysis, of which 3D modeling is now an integral part. The practitioner remains responsible for choosing the appliance, whether it be visible braces, lingual braces, or aligners: the patient does not choose a technique alone. The digital impression is the common starting point for both techniques, each then processing the file in its own way.<\/p>\n<p>Digital impressions and alginate impressions differ in several ways. A 3D digital impression takes 3 to 5 minutes per arch, is performed without paste or nausea, offers an accuracy of 20 to 50 micrometers, immediate visualization on the office screen, instant transmission to the laboratory, permanent and duplicable archiving, and allows for immediate treatment simulation. An alginate impression requires 5 to 8 minutes per arch with a setting time, often triggers a gag reflex, offers an accuracy of 80 to 150 micrometers, does not allow for visualization before pouring, requires physical shipment, a fragile and bulky model, and does not allow for simulation.<\/p>\n<h3 id=\"section-3-1\">The contribution of digital technology to the design of clear aligners<\/h3>\n<p>Clear aligners are custom-made removable trays that gradually move teeth in successive stages. Each tray corresponds to a stage of treatment, a planned tooth movement of approximately 0.2 to 0.3 millimeters.<\/p>\n<p>This level of precision is only achievable with a high-definition digital model. The planning software segments each tooth in the 3D file and then simulates the entire dental trajectory, from the initial position to the final goal. The practitioner adjusts the sequence, validates the intermediate steps, and then initiates manufacturing via 3D printing or thermoforming. Without digital impressions, this customized, serial production approach would be impossible to achieve industrially.<\/p>\n<div class=\"iaba-cards\">\n<div class=\"iaba-card\">\n<div class=\"iaba-card-ico\">\ud83c\udfaf<\/div>\n<h4>Visual simulation<\/h4>\n<p>The patient can see on screen the predicted position of their teeth at the end of treatment, from the first consultation.<\/p>\n<\/div>\n<div class=\"iaba-card\">\n<div class=\"iaba-card-ico\">\ud83d\udcd0<\/div>\n<h4>Encrypted transactions<\/h4>\n<p>Each tooth movement is planned in millimeters and degrees, tooth by tooth.<\/p>\n<\/div>\n<div class=\"iaba-card\">\n<div class=\"iaba-card-ico\">\ud83d\udda8\ufe0f<\/div>\n<h4>Automated manufacturing<\/h4>\n<p>The file directly feeds into the 3D printing or thermoforming of successive gutters.<\/p>\n<\/div>\n<div class=\"iaba-card\">\n<div class=\"iaba-card-ico\">\ud83d\udd04<\/div>\n<h4>Adjustments made along the way<\/h4>\n<p>A new scan currently being processed allows for further refinement of the aligners if necessary.<\/p>\n<\/div>\n<\/div>\n<h3 id=\"section-3-2\">The precision required for custom-made lingual braces<\/h3>\n<p>Lingual braces are brackets bonded to the inside surface of the teeth, invisible from the outside. Unlike standardized braces, each lingual bracket is individually manufactured to fit the shape of the tooth to which it will be bonded. This requirement makes a digital impression essential.<\/p>\n<p>Using the 3D file, the laboratory manufactures brackets whose base precisely replicates the contours of the lingual surface of each tooth. A bonding tray, also created from the scan, allows the practitioner to position the brackets simultaneously and with micrometric precision in the mouth. A discrepancy of just a few tenths of a millimeter in the impression would result in incorrect positioning and less effective treatment.<\/p>\n<div class=\"iaba-callout\" data-variant=\"warning\">\n<p><strong>\u26a0 Health alert:<\/strong> The choice between clear aligners and lingual braces is not based solely on aesthetics. It depends on the type of malocclusion, the periodontal condition, the bite, and lifestyle habits. A personalized assessment absolutely requires a clinical consultation and a thorough examination.<\/p>\n<\/div>\n<h3 id=\"section-3-3\">Facilitating dialogue with the adult patient<\/h3>\n<p>3D visualization also changes the practitioner-patient relationship. Even before starting, the adult sees the current position of their teeth on the screen, then the projection of the expected result. They clearly understand the necessary movements, any potential limitations of what is achievable, and can ask targeted questions. This educational transparency is particularly appreciated by a demanding adult clientele, often living near the border and accustomed to high standards of care.<\/p>\n<div class=\"iaba-ctasplit\">\n<div class=\"iaba-ctasplit-txt\"><strong>Are you considering orthodontic treatment for adults?<\/strong><span>A clinical assessment will determine the technique best suited to your situation.<\/span><\/div>\n<p><a href=\"https:\/\/nicolasbarriere.fr\/en\/contact\/\">Make an appointment \u2192<\/a>\n<\/div>\n<h2 id=\"section-4\">Equipment that has become essential in the Pays de Gex<\/h2>\n<p><strong>The Pays de Gex is among the French territories where the digitalization of orthodontic practices is most advanced, driven by an active adult clientele from across the border accustomed to Swiss healthcare standards.<\/strong> Intraoral scanners are now used in the majority of specialized facilities.<\/p>\n<p>According to the <a href=\"https:\/\/www.insee.fr\/fr\/statistiques\/1405599?geo=EPCI-240100750\" rel=\"noopener\" target=\"_blank\">INSEE territorial data for the Pays de Gex Agglomeration Community<\/a>, The territory has surpassed 100,000 inhabitants and is experiencing sustained population growth, driven by its proximity to the Geneva basin.

The demands of an active adult patient base, often executives in the Geneva area, are driving practices to invest in tools that minimize the time spent in the dental chair. Furthermore, Franco-Swiss patients compare practices on both sides of the border and expect a level of equipment consistent with Swiss standards.<\/p>\n<div class=\"iaba-bento\">\n<div class=\"iaba-bento-item iaba-wide\">\n<div class=\"iaba-bento-ico\">\ud83c\udf0d<\/div>\n<h4>Demanding cross-border clientele<\/h4>\n<p>Adults who work in Geneva devote little time to consultations: the speed of a digital fingerprint naturally fits into this constraint.<\/p>\n<\/div>\n<div class=\"iaba-bento-item\">\n<h4>Mixed insurance files<\/h4>\n<p>The management of LAMal and French supplementary insurance is facilitated by the electronic transmission of 3D files.<\/p>\n<\/div>\n<div class=\"iaba-bento-item iaba-dark\">\n<h4>Population growth<\/h4>\n<p>The regular arrival of new residents creates a continuous demand for adult orthodontics.<\/p>\n<\/div>\n<div class=\"iaba-bento-item\">\n<h4>Digital culture<\/h4>\n<p>The proximity of Geneva&#039;s technology hub promotes patient acceptance of digital tools.<\/p>\n<\/div>\n<\/div>\n<h3 id=\"section-4-2\">What difference does a digital footprint make for a border-area adult?<\/h3>\n<p>For someone who crosses the border daily, every minute counts. A digital impression appointment fits perfectly into a lunch break, with no recovery time or lingering discomfort. The file is sent to the lab instantly, reducing the manufacturing time for aligners or lingual braces.

The intraoral camera does not touch the teeth and does not inject any product. It is a major advantage for patients with a strong gag reflex or a sensitive palate, as it eliminates prolonged contact with an impression tray filled with paste.<\/p>\n<\/div>\n<\/details>\n<details class=\"iaba-faq-item\">\n<summary>How long does it take to complete a full dental model?<\/summary>\n<div class=\"iaba-faq-a\">\n<p>A full arch scan typically takes between 3 and 5 minutes. Recording both arches and the occlusion takes less than 10 to 15 minutes in total. This speed is particularly appreciated by active adults, especially patients living near the border in the Pays de Gex region.<\/p>\n<\/div>\n<\/details>\n<details class=\"iaba-faq-item\">\n<summary>Do digital impressions cost the patient more?<\/summary>\n<div class=\"iaba-faq-a\">\n<p>The digital impression is integrated into the overall treatment plan or initial assessment defined by the practitioner. It is not billed as an additional procedure. The choice of technique is based primarily on the clinical diagnosis and the practitioner&#039;s expertise; the details are presented during the initial consultation as part of a detailed estimate that complies with regulations.<\/p>\n<\/div>\n<\/details>\n<details class=\"iaba-faq-item\">\n<summary>How accurate is an intraoral scanner compared to a traditional impression?<\/summary>\n<div class=\"iaba-faq-a\">\n<p>Studies published on PubMed Central show that a modern intraoral scanner achieves an accuracy of 20 to 50 micrometers across a full arch, which is greater than the precision of an alginate impression (80 to 150 micrometers). This accuracy is more than sufficient for all orthodontic procedures, including custom-made lingual braces.<\/p>\n<\/div>\n<\/details>\n<details class=\"iaba-faq-item\">\n<summary>Can a digital impression be taken if you already have crowns, bridges, or implants?<\/summary>\n<div class=\"iaba-faq-a\">\n<p>Yes, the intraoral scanner easily records fixed prostheses, crowns, bridges, and implant abutments. The 3D file can also be used to simultaneously plan orthodontic treatment and prosthetic care in coordination with referring dentists.<\/p>\n<\/div>\n<\/details>\n<details class=\"iaba-faq-item\">\n<summary>Is any special preparation required before an intraoral scan?<\/summary>\n<div class=\"iaba-faq-a\">\n<p>No specific preparation is required.

En 2026, cette technologie \u00e9quipe la majorit\u00e9 des cabinets d'orthodontie du Pays de Gex et sert de fondation aux aligneurs et bagues linguales. La mod\u00e9lisation offre une pr\u00e9cision de l'ordre de 20 \u00e0 50 microm\u00e8tres, sup\u00e9rieure \u00e0 celle des empreintes \u00e0 l'alginate. L'empreinte num\u00e9rique sans pl\u00e2tre en orthodontie dans le Pays de Gex consiste \u00e0 mod\u00e9liser la dentition en trois dimensions \u00e0 l'aide d'un scanner intra-oral 3D, sans utiliser la p\u00e2te traditionnelle (alginate). La proc\u00e9dure dure g\u00e9n\u00e9ralement moins de 5 minutes par arcade, \u00e9limine le r\u00e9flexe naus\u00e9eux et fournit imm\u00e9diatement un fichier num\u00e9rique exploitable pour planifier un traitement adulte par \n\n## FAQ\n\n### Est-ce que le passage du scanner intra-oral est douloureux ?\n\nNon, la prise d'empreinte num\u00e9rique est totalement indolore. La cam\u00e9ra intra-orale ne touche pas les dents et n'injecte aucun produit. Elle repr\u00e9sente un atout majeur pour les patients souffrant d'un r\u00e9flexe naus\u00e9eux marqu\u00e9 ou d'une sensibilit\u00e9 du palais, car elle supprime le contact prolong\u00e9 avec un porte-empreinte rempli de p\u00e2te.\n\n### Combien de temps faut-il pour r\u00e9aliser une mod\u00e9lisation dentaire compl\u00e8te ?\n\nLe scan d'une arcade compl\u00e8te prend g\u00e9n\u00e9ralement entre 3 et 5 minutes. L'enregistrement des deux arcades et de l'occlusion s'effectue en moins de 10 \u00e0 15 minutes au total. Cette rapidit\u00e9 est particuli\u00e8rement appr\u00e9ci\u00e9e par les adultes actifs, notamment la patient\u00e8le frontali\u00e8re du Pays de Gex.\n\n### Les empreintes num\u00e9riques co\u00fbtent-elles plus cher au patient ?\n\nNon, l'empreinte num\u00e9rique est int\u00e9gr\u00e9e dans le plan de traitement global ou le bilan initial d\u00e9fini par le praticien. Elle n'est pas factur\u00e9e comme un acte suppl\u00e9mentaire. Les tarifs sont pr\u00e9sent\u00e9s lors de la consultation de bilan dans le cadre d'un devis d\u00e9taill\u00e9 conforme \u00e0 la r\u00e9glementation.\n\n### Quelle est la pr\u00e9cision d'un scanner intra-oral compar\u00e9e \u00e0 une empreinte classique ?\n\nLes \u00e9tudes publi\u00e9es sur PubMed Central montrent qu'un scanner intra-oral moderne atteint une justesse de 20 \u00e0 50 microm\u00e8tres sur une arcade compl\u00e8te, soit une pr\u00e9cision sup\u00e9rieure \u00e0 celle d'une empreinte \u00e0 l'alginate (80 \u00e0 150 microm\u00e8tres). Cette pr\u00e9cision est largement suffisante pour tous les actes orthodontiques, y compris les bagues linguales sur-mesure.\n\n### Peut-on faire une empreinte num\u00e9rique si on a d\u00e9j\u00e0 des couronnes, bridges ou implants ?\n\nOui, le scanner intra-oral enregistre sans difficult\u00e9 les proth\u00e8ses fixes, les couronnes, les bridges et les piliers implantaires. Le fichier 3D peut d'ailleurs servir \u00e0 planifier simultan\u00e9ment un traitement orthodontique et des soins proth\u00e9tiques en coordination avec les correspondants.\n\n### Faut-il une pr\u00e9paration particuli\u00e8re avant un scan intra-oral ?\n\nAucune pr\u00e9paration sp\u00e9cifique n'est demand\u00e9e. Un brossage des dents juste avant le rendez-vous suffit. Au cabinet, le praticien proc\u00e8de \u00e0 un s\u00e9chage d\u00e9licat des surfaces dentaires pour optimiser la qualit\u00e9 du scan, sans aucune contrainte pour le patient.\n\n### Le fichier 3D de ma bouche est-il conserv\u00e9 en s\u00e9curit\u00e9 ?\n\nOui, le fichier num\u00e9rique est int\u00e9gr\u00e9 au dossier m\u00e9dical du patient et conserv\u00e9 selon les r\u00e8gles du secret m\u00e9dical et du R\u00e8glement G\u00e9n\u00e9ral sur la Protection des Donn\u00e9es (RGPD). Il n'est partag\u00e9 qu'avec les intervenants n\u00e9cessaires au traitement (laboratoire, correspondants) et sur accord du patient.\n\n### Pourra-t-on voir \u00e0 quoi ressemblera mon sourire \u00e0 la fin du traitement ?\n\nOui, la plupart des logiciels de planification permettent de visualiser la position finale des dents d\u00e8s la premi\u00e8re consultation de projet. Cette simulation est un support de dialogue, elle illustre l'objectif th\u00e9rapeutique vis\u00e9, mais le r\u00e9sultat r\u00e9el d\u00e9pend ensuite du bon d\u00e9roulement clinique et de la coop\u00e9ration du patient.\n\n## Source\n\nArticle publi\u00e9 par  ().\nR\u00e9viseur : , .","_llms_full_txt":"","footnotes":""},"categories":[122,135],"tags":[],"class_list":["post-35993","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-alignement-dentaire-par-aligneurs","category-orthodontie-de-ladulte"],"acf":[],"_links":{"self":[{"href":"https:\/\/nicolasbarriere.fr\/en\/wp-json\/wp\/v2\/posts\/35993","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nicolasbarriere.fr\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/nicolasbarriere.fr\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/nicolasbarriere.fr\/en\/wp-json\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/nicolasbarriere.fr\/en\/wp-json\/wp\/v2\/comments?post=35993"}],"version-history":[{"count":4,"href":"https:\/\/nicolasbarriere.fr\/en\/wp-json\/wp\/v2\/posts\/35993\/revisions"}],"predecessor-version":[{"id":36151,"href":"https:\/\/nicolasbarriere.fr\/en\/wp-json\/wp\/v2\/posts\/35993\/revisions\/36151"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/nicolasbarriere.fr\/en\/wp-json\/wp\/v2\/media\/35974"}],"wp:attachment":[{"href":"https:\/\/nicolasbarriere.fr\/en\/wp-json\/wp\/v2\/media?parent=35993"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/nicolasbarriere.fr\/en\/wp-json\/wp\/v2\/categories?post=35993"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/nicolasbarriere.fr\/en\/wp-json\/wp\/v2\/tags?post=35993"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
