Invisalign is one of the most sophisticated systems available that can straighten your teeth in a virtually invisible and aesthetically pleasing way. The Invisalign system uses polyurethane, a transparent plastic that allows for a certain level of elasticity. This elasticity allows the teeth to shift little by little from their initial position of misalignment to the proper position. The extent of this shift depends more or less on the extent of the initial misalignment.
The procedure is done in stages, each stage corresponding to a different aligner. The total duration of the treatment can vary from 2 months to 2 years, depending on the patient.
Developed about twenty years ago, Invisalign is still largely unknown to the public, and few dentists recommend it. Indeed, many dentists show reluctance to employ a device such as this.However, in recent years, Invisalign has experienced exponential growth. In a short time, it will no doubt become one of the most widely-used devices.
