By using a series of clear, removable aligners, Invisalign straightens your teeth without the brackets or wires used in traditional braces. The course of treatment involves changing aligners approximately every two weeks. Unlike braces, these clear aligners can be removed while you eat and brush your teeth as usual. An average Invisalign course of treatment takes about a year, but treatment time can range from 9-15 months. The patient is seen every 6 to 8 weeks for adjustments and to check progress of repositioning. At regular intervals, you'll receive a new set of custom-molded clear aligners to continue the straightening process. Upon completion, a total of 18-30 aligners are used to treat the patient. The aligners are specifically created to gradually reposition your teeth. Patients opt for Invisalign because they are more visually more appealing. Since Invisalign is practically invisible, there's no unwanted attention to the patient’s mouth. In fact, very few people notice the aligners at all. They're comfortable to wear and remove easily when you eat, brush, and floss. With Invisalign, patients have little or no irritation to the gums, cheeks, and/or tongue, as traditional braces tend to rub inside a patient’s mouth. Invisalign is also an excellent alternative for patients allergic to the metals used in traditional braces. As Invisalign invisibly straightens your teeth, it can also do great things for the health of your mouth. Teeth that are crowded or too widely spaced can create unhealthy conditions, including swollen gums, redness and pocketing, all of which are signs of periodontal disease. Patients with Invisalign have overall healthier gums. Clinical studies have shown that gum health may improve with the use of Invisalign during orthodontic treatment¹. Properly aligned teeth can help gums "fit" tighter around each tooth², which may lead to better periodontal health. Unlike braces, with Invisalign, patients can brush and floss normally, which can help prevent tooth decay and periodontal disease. The design allows for easier cleaning for both the patients and dentist. Unlike traditional orthodontics or braces, Invisalign has no metal bands or wires to trap food and plaque. Maintaining a good oral hygiene program will also reduce chances of plaque buildup, tooth decay and periodontal disease. In addition to health benefits, Invisalign can correct other problems. For some people, incorrectly positioned teeth and jaws can exacerbate speech difficulties and chewing problems. Correcting your bite by straightening your teeth can help improve both chewing and speech. Indirectly, Invisalign also lowers the risk of trauma and abnormal wear of the patient’s teeth and mandible. Properly aligned teeth can be less stressful on supporting bone and jaw joints. Dental science technology advances have allowed Invisalign to be specifically tailored for each patient. For every patient, each aligner is customized for each tooth of each phase of repositioning during their treatment. After evaluating a patient’s goals and lifestyle choices a proper treatment plan is determined. In office, special impressions are taken using putty polysiloxane along with x-rays, photographs and bite registrations. All of which are sent to Invisalign laboratories. At the laboratory, a CT scan is made from the patient’s dental impressions. The CT scan produces an extremely accurate, 3dimensional digital model of the patient’s teeth. Computer Aided Design (CAD) software is then used to simulate the movement of teeth during treatment. Then, the dentist/orthodontist reviews, modifies, and approves the treatment plan before the aligners are created. Invisalign then uses advanced stereolithography (SLA) technology
to build precise molds of the patientâ€™s teeth at each stage of their treatment. In approximately one month, individualized, custom-created clear aligners are made from these models and sent to the doctor's office. Like brackets and arch wires are to braces, Invisalign aligners move teeth through the appropriate placement of controlled force on the teeth. The principal difference is that Invisalign not only controls forces, but also controls the timing of the force application. At each stage, only certain teeth are allowed to move, and these movements are determined by the orthodontic treatment plan for that particular stage. This results in an efficient force delivery system. Talk about Invisalign express????
