INTRODUCTION
Crowded teeth can be very troublesome and aesthetically not pleasing. Traditionally the only way to correct them is to have traditional braces which must be worn between 1 or more years to get the teeth straightened.
Traditional braces are most the effective way to align teeth as it is a technology that has been around for more than one hundred years. However, braces are difficult to maintain. Plaque easily accumulates around teeth and it is impossible to floss them. Prolonged poor oral hygiene means you may get decalcified spots on your teeth or worse, dental decay and gum disease.
With the advent of digital technology it is now possible to make 3D printed models. Sequential movement of teeth can be modeled and made into aligners which compliment them.
