In Dr. Keith Bracy's experience, for a very limited number of cases, it is advisable to do only one arch of Invisalign. You might be concerned with straightening only your upper or lower teeth with Invisalign. Yes, Invisalign is available for only the bottom teeth or the top teeth, but it most cases both arches should be treated. The reason being is that you must have a stable bite or occlusion at the end of your Invisalign alignment treatment. If you solely move or straighten just your bottom or upper teeth, the opposing teeth will not align properly when you bite down. You might end up with a bite that is not stable or becomes disrupted by interfering teeth and does not close effectively. Opposing teeth must come together properly to have a stable bite and if you only use Invisalign on one arch of teeth, they might not come together properly.
You might be tempted to ask your dentist if you can do Invisalign on one arch only because you want to lower the cost of your orthodontic treatment. However, this isn’t true for most. Only using 1 clear aligner vs. 2 clear aligners does not equate with half the fee of Invisalign treatment. The costs of the procedure are very similar since the same amount of time, materials and clinical expertise are needed when doing dual arch vs. single arch. The laboratory fee for the dentist or orthodontist is nearly the same too.
In some cases of minor teeth movements or straightening, one arch treatment is advisable. The only real way to know if you can treat just one arch is to have an orthodontic consultation and start your Invisalign treatment planning process.
