If you have been completing RPE, RME, and Schwartz Expander cases, it’s important to take steps to minimize revisions and refinement cases. Indeed, while you might notice great results with these cases initially, it’s quite possible to notice relapse once the expanders are removed.
But is this normal? How much relapse is normal, and should you over expand to account for this? We’ve outlined some of the key things you should know as follows to help you ascertain how to approach these cases.
How Much Relapse is Expected in Skeletal Expansions?
If you’ve completed RPE, RME, or Schwartz Expander cases before, you may have noticed revisions and refinement being needed after the case. This is due to relapse, but it’s important to understand what’s normal here.
If you’re completing these processes, taking things slow and steady can help reduce the amount of relapse your patients experience.
Now, there’s no set figure for how much relapse your patients will see. Most will experience between 10 and 20% relapse. However, relapse of 30% or more is potentially possible. This can be frustrating if you thought you’d completed the ortho treatment without needing revisions.
Should I Over-Expand to Prevent Revisions and Refinement Cases?
Generally speaking, you may want to over expand slightly to reduce the need for revisions and refinements. However, you should only go over carefully. Make sure you know when to stop expanding in time to prevent damage to the patient; for example, over-expanding could result in a Brody or Buckle crossbite.
