Abstract: Invisible aligner technique without brackets has been paid more attention to by both orthodontists and patients with the advantagebeings of being esthetic， comfortable， safe， convenient，etc. More than 100 million patients has been treated with the technique during the past few years worldwide， outside of China. Yet in China， there has been relatively less application and treatment clinically， which should be further applied and discussed. Detailed and accurate diagnostic materials needed are the basis of successful treatment， while comprehensive diagnosis and treatment planning relates directly to the final treatment results. There should be indication for the technique of course， which should be based on the kind and severity of the malocclusion， and the orthodontists’ clinical experiences as well. Attachments and interproximal reduction should be properly selected and manipulated. There should be more and wider application of this new orthodontic technique with the development of relative materials and basis techniques.
