Tooth movement can be performed by using sequential positioners, which are created by changing tooth positions on set-up models to replicate treatment progression. The notion is based on Kesling's 1945 positioner concept, albeit it’s subsequent application to splint therapy was labour consuming and did not result in precise tooth movement. Invisalign was created in 1997 by Align Technology, Inc (Santa Clara, CA, USA) by utilising 3D imaging technology to address these issues and allow for large-scale customisation. Their approach has many advantages, but it has certain limits, which are explained in this article. Patients increasingly prefer more aesthetically pleasing types of orthodontic therapy. Clinicians must understand the indications and limitations of such invisible therapies in order to adequately inform their patients. One of the most consistently requested practices throughout the COVID-19 pandemic has been to keep our hands away from our face and mouth. This is to limit the spread of disease and slows the rate of infection. Unfortunately, patients cannot avoid touching their mouths during the treatment process. This means it's more important than ever to practice good hygiene, which clearly is usually an easy task with Invisalign’s clear aligners.
