Invisalign
It is a sequential aligner orthodontic system which used plastic trays to gradually move the teeth to their desirable position. Depending on the case and amount of complexity of it, the number of aligners will differ. Each aligner will be worn for two weeks before moving to the next one. Most of the time there would be some small tooth color attachments to be glued to the teeth surfaces to act like a handle for aligners to grab and pull or push the teeth more effectively.
Each aligner usually moves the teeth or some of them for about 0.25mm in a period of two weeks. This makes the orthodontic treatment safer and less painful.
In recent years due to improvement in technology and knowledge, this system works way better than the past and now we are able to do more movements than we were able to before.
Invisalign comes in 3 different setup. Up to 7 aligners, up to 14 aligners and more than 14 aligners. The 7 aligner set is called “i7” which can be useful when movements are minimum. If we need more than 7 but less than 14 it is called “Lite”. And more than 14 is called “Full”. Only the “Full” version comes with free refinement at the end which means if patient is not 100% satisfied with result, we can take another impression and request for more aligners to achieve what is ideal at no extra cost.
There are some similar systems around which work the same but are new in the market and not as famous as Invisalign. An example of it is, ClearCorrect.
