What's the Average Number of Trays Needed for Invisalign Refinement?

There is no average time or number of trays for Invisalign refinement.  If an error was caught early in treatment and the case was due to go 30 aligners, then there may be 20 more to go.  If an error was caught at the end, then only 5 or 6 might be needed.

There are too many variables to be able to say an average.

It has been my experience that the number of original treys that you have from Invisalign treatment is usually two to three times the number of Invisalign refinement treys that you will receive.  In other words, if you start with 20 Invisalign trace initially, the refinements would have be any where between 7 to 10 trace.  Of course, this depends on each specific patient’s malocclusion as well as the severity of crowning pretreatment.  Our goal in Invisalign treatment is to get the majority of the movements with initial treys and then the smaller movements with the refinement treys.  Hence, most of the time, we are able to do this in 10 treys or less.

There is no average time or number of trays for invisalign refinement.  Too many variable to give an estimate.  I have had patients that need 6-10 aligners and i have patients that need 20 aligners for refinement.
