Does It Take Longer to Correct an Overbite with Invisalign?

In general, overbites are caused by misalignment of the jaws and teeth in vertical and horizontal directions.  Invisalign is not suited to the types of tooth movements required to correct overbites unless the overbite is caused by the upper front teeth being spaced apart in a situation where the vertical overlap of the upper and lower teeth is not too great.  It is possible to use 'elastics' with Invisalign to help correct an overbite, but the success of this technique may be limited to minor overbites.  You should have a consultation with an orthodontist who is skilled at both Invisalign and braces to get an honest opinion of which appliance will work for you.

The average treatment time for Invisalign cases is 1 year according to Align Technology (makers of Invisalign). Conventional braces will treat similar cases in similar time. HOWEVER, there are many dental problems that Invisalign is NOT ideally suited to treat and deep overbites is one of them. You should consult with a dentist or orthodontist who is more than happy to use either treatment options in order to get an honest and accurate opinion about which treatment option is best for you. If you consult with a dentist who only does Invisalign it's like the proverbial repairman who only has a hammer in his tool bag and therefore uses a hammer to try and fix everything. 

While length of treatment is important to patients AND the treating doctor, what should ultimately dictate the treatment length is resolving all of the patient's concerns and giving the patient a beautiful AND highly functional smile and bite. 

Good luck!
