CLEAR ALIGNERS A NEW TECHNIQUE IN ORTHODONTICS

Prior to 1998, orthodontic clear aligner treatment was predominantly for very minor tooth movement usually at the end or orthodontic treatment or to treat minor alignment relapse. Clear aligners use computerized 3D technology to visualize and move the teeth in a virtual model. This technology along with advances in 3D printing and manufacturing efficiencies allow aligners to be produced in a large number and in a timely fashion. Initial cases weremild crowding or spacing which progressto cases that need expansion and malocclusion correction. This clear aligner technique is continually evolving because of research and development in materials, and manufacturing techniques, auxallaries and computer programming of tooth movement
