Invisalign straightens the teeth using a virtually invisible set of aligners (a set of clear plastic trays) which are created and customized specifically to your teeth to gradually and gently shift them into place. Treatment progresses by changing your aligners every two weeks until the desired final position has been achieved. The complexity of your bite issues determines the duration of the treatment, which averages 9 to 18 months and is comparable to traditional braces treatment time. 3D computer designed images of the proposed treatment plan, created before your treatment has started, allow you to see how your teeth are expected to look at the end of the treatment. Aligners can be removed to maintain good oral hygiene (brushing and flossing) and to eat. There is no restriction as to food and drinks. Unlike traditional teeth straightening treatments, aligners are bracket and wire free. Invisalign is sold in over 45 countries worldwide, including the USA, Canada, China, Japan, various European countries and countries in the Asia Pacific region. It is also available via distribution in smaller developing countries of Europe, the Middle East, Africa and Latin America. More comprehensive information on the Invisalign treatment can be obtained at the Supradent Clinic from Dr Malgorzata Adamczyk DDS, PhD, our Invisalign-certified doctor.
