Each tray applies calibrated forces to targeted teeth, and the patient changes them every 7 to 14 days according to a treatment plan designed in 3D by the orthodontist.<\/p>\n<\/div>\nThe principle is based on progressive orthodontic movement: each aligner<\/dfn> (Custom-made clear aligners) are slightly different from the previous method and exert controlled pressure on a few teeth at a time. Over the weeks, this series of micro-movements leads to the desired alignment. A complete treatment typically includes between 20 and 60 aligners, sometimes more for more complex cases.<\/p>\n\nClear aligner<\/dfn> Removable tray made of medical plastic material, custom-made by CAD\/CAM (computer-aided design and manufacturing) from an optical impression, and intended to gradually move teeth according to a digital orthodontic treatment plan.\n<\/div>\nFrom optical impression to the first aligner<\/h3>\nThe production line always starts with a optical imprint<\/dfn> This procedure is performed using an intraoral scanner. No more unpleasant impression paste: the practitioner inserts a small camera into the patient's mouth, and a complete 3D model of the dental arches is obtained in minutes. This digital file is then used to plan each step of the treatment on screen.<\/p>\n\n\nInitial clinical assessment<\/h3>\nClinical examination, panoramic radiographs and cephalometric radiography, intra- and extra-oral photos, discussion of aesthetic and functional expectations.<\/p>\n<\/li>\n\n3D Digital Footprint<\/h3>\nComplete intraoral scan of both arches and occlusion, without impression paste, in just a few minutes.<\/p>\n<\/li>\n\nSimulation and treatment plan<\/h3>\nDigital planning movement by movement, preview of the final result and validation by the patient.<\/p>\n<\/li>\n\nManufacturing and installation<\/h3>\nLaboratory fabrication of the series of custom-made gutters, possible placement of small composite pads (attachments) to guide movements.<\/p>\n<\/li>\n\nActive wearing of aligners<\/h3>\nWear for 22 hours a day, removal only for meals and brushing, tray change every 7 to 14 days at home.<\/p>\n<\/li>\n\nControls and restraints<\/h3>\nCheck-ups every 6 to 8 weeks, then placement of a restraint at the end of active treatment.<\/p>\n<\/li>\n<\/ol>\nWhy 22 hours of wear per day?<\/h3>\nClinical studies published on PubMed Central regarding the clinical effectiveness of aligners<\/a> Studies confirm that wearing the appliance for less than 20 hours per day significantly slows down the intended tooth movements and can compromise the outcome. The 22-hour threshold therefore allows a reasonable margin for meals and hygiene, while ensuring the biomechanical effectiveness of the device.<\/p>\n\nHealth alert point:<\/strong> Aligners only work when they are in the mouth. Irregular wear (for example, frequent removal at work or forgetting to put them in at night) can lengthen the treatment time, create a misalignment with the next aligner, or even require taking new impressions.
