Invisalign:A Review of Literature

The purpose of this narrative review was to analyze publications that assessed the accuracy and efficiency of the Invisalign® system. A search strategy to identify articles that referenced Invisalign®, which were published between 2001 and 2019 was adopted and the relevant articles were segregated and perused to evaluate the accuracy of Invisalign technology in achieving predicted tooth positions with respect to direction of tooth movement and tooth type as also its indications, limitations, advantages & disadvantages. It could also be surmised that in comparison with the traditional fixed appliances, patients treated with Invisalign had a better periodontal health but the results achieved with it were not as accurate as thoseachieved by treatment with fixed appliances.
