![]() ![]() There are risk factors, including operator-related and patient-related factors, that may result in attachment loss. Attachment loss can induce significant clinical problem that may prolong treatment time, increase the number of revisit, and the prognosis of the treatment. Bond failure or patient neglect can cause attachment loss from the tooth surface. Attachments consist of composite resin bonded to the tooth surface. Aligner attachments have different shapes that help to increase the retention and provide better control of certain tooth movements whenever needed. In most cases, attachments are automatically placed in specific locations on teeth that determined by the computer algorithm, and they control the application point of the force, the direction of the force, and the amount of force applied. ![]() Īligner attachments serve as an important auxiliary device for many clear aligners to transfer the forces from the aligner to the tooth root and crown. The dentition is planned for movement with a computer-aided design to prescribe varying amounts of corrections to the individual teeth. The clear aligner therapy differs from traditional fixed appliances in that clear aligners rely on a series of appliances fabricated from a transparent polymer that covers the teeth. Furthermore, it has been reported that patients treated with aligners may experience less root resorption and less risk of developing white spot lesions (WSLs) comparing to traditional fixed appliances. found that clear aligners can induce nonpathogenic changes of the subgingival microbiome in the first three months of treatment. In addition, studies have found clear aligners may be more amenable to periodontal health than fixed appliances thus, they are recommended for patients at high risk of developing gingivitis. Īlthough orthodontic fixed appliances have become smaller and more esthetically acceptable over the years, they still receive more critics than clear aligner for their unpleasant look and the inconvenience of using. With the help of these devices, orthodontists are able to treat a wide range of malocclusions, from mild crowding to more severe cases. ![]() first introduced the Invisalign to the orthodontic market, as one of the pioneers of clear aligner therapy, many different types of clear aligners have been developed and became commercially available. Clear aligner orthodontic treatment is a quickly growing sector in orthodontic technology due to the increasing demand. ![]()
