Invisalign is a more complex process in which some of the more complicated diagnostics, design, and detailed planning of each step of treatment are involved. Because invisible orthodontics, especially bracketless invisible orthodontics, involves digitization, it is important to data the teeth in three dimensions. After obtaining the 3D data, the data is then submitted to the fabricator to develop each step of the orthodontic process, and the doctor is involved in the process, actually taking each step of the teeth into great detail, before the normal aligners are generated and worn every month. The orthodontic treatment is digitally designed for the patient step by step. There is also a very important process is to do this after the maintenance, for example, after many invisible orthodontic treatment now have to do retainers, this maintenance is more important than orthodontics, because the possibility of relapse of orthodontics, so that later there is also the issue of maintenance. At the same time invisible orthodontic treatment there is also a very important process is the possibility of loss of control in the middle, as well as the restart in the middle. For the patient, it may not be enough to do one design, but 1-2 more times in between, so as to perfect the treatment.
