Both Invisalign and Braces are used for the objective of aligning teeth. Invisalign treatment involves using a series of clear retainers that will over a period of time align your teeth. Successful results within expected time period relies a lot on patient compliance to keep the retainers in for at least 20hr/day. With braces, the patient cannot take them off so, they will do the job irrespective. However keeping good oral hygiene with braces can be challenging. Similar results can be achieved by using either of the two options in most situations. In case of more complex teeth movements and bite modifications, braces can provide more directed, predictable and stable outcome as compared to Invisalign. Having said that there are very few situations where braces are preferred over Invisalign.
