Review of Invisalign Effectiveness

3 Rating(s).

Posted on By Steven Hunt In Orthodontics

The Invisalign appliance has been in the market for nearly 20 years. Its popularity has largely been fueled by its superior aesthetics over conventional fixed braces especially among the adult population. The early appliances were limited in their range of movements and therefore largely restricted to correction of simple malocclusions. With continuous research and improvements in software and material, the Invisalign appliance is now also used by some practitioners to treat more complicated malocclusions.

Studies comparing treatment with the Invisalign system with conventional fixed appliance have largely been retrospective, with only a handful of randomized controlled trials, often considered the gold standard of study design. The debate among the dental community thereby still persists- is Invisalign just as effective as fixed appliances? A few authors have reviewed the literature available so far, disregarding those deemed to be of poor design or of excessive bias.

The bulk of evidence indicates that Invisalign can be used to treat mild to moderate cases, preferably non-extraction. However the results are not as precise as that with fixed appliances. Fixed appliances are preferred when treating complex cases due to greater control of tooth movements.

Invisible braces are really a great invention over traditional braces.


Invisalign uses a series of customized, clear aligners to straighten teeth in a quicker amount of time and with fewer office visits than traditional braces. Thousands of orthodontists in the United States and Canada use Invisalign braces to accurately and effectively treat their patients. To review pros and cons about invisalign, check this page out.
