Almost 100 years have passed since Remensnyder proposed aligner orthodontics in 1926, and with the introduction of CAD/CAM by Align Technology with Invisalign, the last 25 years have seen aligner orthodontics applied in many clinical practices worldwide. More recently, revolutions in the industry, including CAD, simulation software for orthodontic treatment with aligners, the increasing performance of 3D printers, and the emergence of new aligner materials have triggered an increase in the quality of digital in-office aligner systems. Not only has aligner production shifted from 3rd party commission to in-house production, but the concept of aligner orthodontics has also changed dramatically, changing the workflow of treatment, treatment planning, and treatment outcomes. The conventional wisdom in aligner orthodontic treatment, which is commissioned by conventional companies, is poised to change drastically, here and now. This lecture will redefine the fundamental concept of aligner orthodontic treatment.

Shape memory aligners: A new paradigm
Course Ravindra Nanda (USA) , Kenji Ojima (Japan) Palas Congress Hall, Sala CHOPIN
Recent studies have confirmed that thermoform aligners do not have the predicted efficacy for various orthodontic tooth movements. Primary problem has been the plastic material used for thermoformed aligners. It is stiff, does not adapt to teeth unless a bite force is used for first two days which results in its deformation. Along with deformation at the gingival level the magnitude of force delivered is very high and decay is very fast, both are undesirable.
Recently Graphy from Korea has introduced new resin material TA-28 which has shape memory properties and allows direct printing of aligners. This presentation will describe the evidence-based studies, will discuss the workflow and advantages of using shape memory aligners with examples of treated patients.
