CLEAR ALIGNERS IN ORTHODONTICS

Clear aligners are one of the orthodontic appliances to align teeth. They provide an aesthetic and comfortable treatment experience, facilitate oral hygiene, cause less pain as compared to fixed orthodontic appliances, reduce the number and duration of appointments, and require less emergency visits. They work on the same principle work as traditional orthodontic appliances work by applying carefully controlled forces to teeth which are determined by software to move them into a better position except instead of metal, they are made of clear, flexible plastic. It uses the Computer-Aided Design & Computer-Aided Manufacturing (CAD-CAM) technology, combined with advanced imaging and 3-D printing technology like stereolithography for fabricating a series of custom made appliances that are both esthetic and removable, that could affect various types of tooth movements.
