Are there studies that compare how well Invisalign works compared to regular braces?
Invisalign vs Braces
Since 2005, many studies about the clinical effectiveness have been published; for example in the UK, Dr Paul Humber has analyzed 100 back-to-back Invisalign cases.[4] In the USA, Akhlaghi and colleagues compared treatment with the Invisalign system with treatment with conventional braces and concluded that "conventional fixed appliances achieved better results in the treatment of Class I mild crowding malocclusions".[15] In a comparison of outcomes between the two approaches, Kuncio et al.[11] reported that in the Invisalign group: "the mean alignment of the Invisalign group was superior to the Braces group before and after the retention phase,… . Therefore… they appear to have the same, if not better, overall alignment scores." In a larger study[16] Djeu and colleagues had similar findings to Akhlaghi above. They felt that "The strengths of Invisalign were its ability to close spaces and correct anterior rotations and marginal ridge heights." They added "Invisalign patients finished 4 months sooner than those with fixed appliances on average."
Other Facts & Sources on Invisalign
The first book devoted to the treatment technique is The Invisalign System by Orhan C Tuncay, published by Quintessence in July 2006. This well-illustrated volume provides an interesting and useful insight into the technology of Invisalign aligners and their clinical application.
Invisalign is designed, manufactured, and marketed by Santa Clara-based medical-device company Align Technology, Inc. Align says that over 35,790 doctors are trained to provide Invisalign treatment in the U.S., with 48,130 doctors worldwide.[1] As of January 29, 2008, Align Technology has 1,307 employees worldwide, and has manufactured more than 32 million Invisalign aligners.
