Would changing Invisalign weekly effect the overall goal?

Question

My orthodontist, who I have already scheduled my Invisalign with, said that he did things a little differently than others in that he does smaller movements, but with weekly aligner changes rather than changing them every two weeks. Everywhere I've read states that changes should be done by a minimum of every two weeks. He also stated that he does this with every patient, and it is not specific to my case. Will this effect the overall goal?

So, your dentist tells you to switch trays once every week, instead of once every two weeks and you are concerned.  Well, let me tell you now that you have nothing to worry about and here's why.  When your dentist chooses your treatment plan with Invisalign, they can choose to move your teeth once every week, once every two weeks or once every three weeks.  The default is every two weeks and this is the most common treatment selected, but some dentists choose much smaller movements spread over double the amount of trays with more frequent tray changes.  I'll show you an example below:Patient A, B, and C will have the exact same teeth movements and will both take 16 weeks to complete.Patient A - in 18 weeks, it will take 9 trays, with tray change every 2 weeks. (most common)Patient B - in 18 weeks, it will take 18 trays, with tray change every 1 week. (moves teeth in smaller increments)Patient C - in 18 weeks, it will take 6 trays, with tray change every 3 weeks. (moves teeth in larger increments)In my example, each patient will have the exact same outcome, but with a different number of trays.Good luck and I hope this helps a lot.
