Invisalign is a more esthetic alternative to braces and are used to straighten teeth. Braces are made up of metallic teeth aligners that are often considered unaesthetic. The use of Invisalign is increasingly popular due to the appearance of the device and the fact that it may be removed.
Invisalign is a teeth-straitening device made up of a series of transparent teeth aligners, made of quality polyurethane that is well tolerated by the gums. Invisalign is often compared to braces, but the main difference is the appearance. Invisalign is also a removable solution and some dentists consider the device less effective due to this fact, as it will not correct the teeth when removed.
Invisalign has been introduced by a company known as Align Technology in the early 2000s. The product is easy to apply and can be removed at any time for eating or cleaning and this is clearly an advantage, as many patients wearing the traditional braces may have side effects such as tooth decay and teeth demineralization due to the fact that the device cannot be removed.
A treatment with Invisalign should last between 12 and 18 months, provided the patient wears the device for at least 20 hours per day. However, the results may depend on the age of the patient as well as the initial condition of the teeth.
Some teeth may not be corrected with the use of Invisalign (i.e. round lower premolars). Invisalign is more expensive than other teeth straightening products on the market.
