Invisalign is a cosmetic alternative to the more traditional braces. Invisalign treatment involves the use of sequential clear aligners to align the teeth and correct the bite. The aligners are changed weekly or as prescribed by your orthodontist.
The Invisalign company has been around since the late 1990’s, but the underlying concept of using clear aligners to move teeth has been around much longer (since at least the 1950’s). In the last 20 years, there are now over 6 million patients that have been treated with Invisalign worldwide.
Patients interested in Invisalign will need to have digital scans (moulds) of their teeth taken first. These scans are uploaded to Invisalign. Your orthodontist then checks and modifies the digital plan on the computer. When he is satisfied with the proposed treatment, sequential aligners are fabricated. The aligners are all slightly different, and are staged to move the teeth up to 0.2 mm per aligner or up to 1 degree of rotation. Sometimes additional aligners are required, but this is generally included in the original treatment cost too.
Invisalign is fast gaining in popularity, but there are still some cases where Invisalign treatment is either not suitable or less efficient than the more conventional braces. Your orthodontist can best advise you if Invisalign is a suitable treatment option.
