Should I Restore Abfractions Before Starting a Clear Aligner Treatment Plan?

When creating your clear aligner treatment plans, knowing how to approach cases such as abfractions is crucial. Luckily, we’ve outlined a few key things you should know to help with this to help.
Should I Restore Abfractions Before Starting a Clear Aligner Treatment Plan?
Generally speaking, whether you should restore abfractions before starting a clear aligner treatment plan should be based on the opinion of a professional restorative dentist. However, if you do decide to go ahead with clear aligners on an abfractions patient, drawing up a custom, special informed consent document is vital; however, this may not necessarily be enough to cover you if issues arise due to treating an abfractions patient who should have undergone restoration first.
The Risk of Using Clear Aligners for Abfractions Without Restoration
It is possible to scallop around the abfractions with the trim line, this can alter the way that force is applied to the teeth, thus impacting the progression of the case (and causing more unpredictable movements accordingly). However, if you decide to take on an abfractions case with clear aligners without restoration, keep the type of plastic used for your clear aligners in mind when determining the correct brand to use. Abfraction cases may be more prone to snapping, especially with alternative clear aligners that use a more rigid plastic than Invisalign.
With that being said, overall, we recommend that you restore abfractions before completing the clear aligner treatment plan to avoid being liable for issues that may arise down the line.
