If you don't need refinement, your tooth movement is complete.
Your orthodontist may help you equilibrate the incisal edges of your teeth. This means that they will smooth out the edges that are chipped, but there is a limitation to the amount of correction that can be made, depending on the size of the chip. We describe it as something like a manicure for the teeth. If the chip is too large, you may require restorative work at the dentist.
Retainers for Invisalign patients include:
-the last set of aligners
-fixed lingual retainers (the wires on the inside of the teeth)
-essix retainers (clear retainers similar to your aligners, but lab or in-house fabricated)
-Vivera retainers (a subscription from Invisalign for 4 sets of retainers, with the first set being fit in the office. The remaining are mailed every 3 months to the office or to your place of residence. They look like the aligners but are slightly more sturdy).
Keep in mind that if you have some adjustment to your teeth, you will likely want a new impression so that your teeth fit properly in the retainer.
