Clear aligners, also called invisible aligners, are a type of orthodontic treatment that corrects misaligned or crooked teeth. They are a virtually invisible and removable alternative to braces designed around convenience and flexibility.
Aligner trays are custom-built for every patient and the duration to complete the treatment depends on the severity of teeth misalignment (malocclusion).

Clear aligners can treat a variety of different cases, including:
Crowded Teeth ,Overbites ,Diastema ( gaps/ space between the teeth), Open Bites.

Some times clear aligners are very usefull as a short duration treatments ( some weeks)  prior to dental implants placement in order to get the appropiate space and positions.
