• Clear aligners are transparent / invisible that are meant for teeth straightening. These are made with special materials that are as strong as the traditional braces.
• Clear aligners have been the current trending and on demand teeth braces for the past few years now. They have become an advantage for those people experiencing teeth positioning problems and who don’t like wearing the traditional wired braces. They are popular for their plastic and a clear body that makes them invisible. Hence the name Invisalign braces. The invisible teeth braces are said to be effective on crowded teeth and incorrectly spaced teeth that are not more than 6mm apart. So, conventional or wired braces are for more severe teeth positioning woes whereas invisible aligners serve for mild to moderately crowded teeth.
• Unlike the conventional ones, the invisible teeth aligners are not permanently fixed and are worn stage by stage as suggested by the orthodontist.

Procedure to wear invisible dental braces

• As per the current position of the crowded or unevenly placed teeth or as per the
  requirement of the patient, the orthodontist develops the final model and using some
  digital moulds few braces are suggested stage by stage. In simple terms, one
  particular invisible teeth braces are fixed for a couple of weeks for at least 22 hours a
  day to move the teeth to the first level of the required position. This process
  continues for another few stages where the teeth are moved to the desired position
  level by level using the clear braces. On average, it takes 12 to 18 months for the
  invisible braces treatment to work and show their effect.
