Smilelign is an aligner system that makes use of 3D CADCAM technology to produce invisible orthodontic aligners. The procedure begins with taking dental impressions of the patient's teeth.The records are sent to Smilelign along with specific instructions of how the teeth need to move. The process of making the aligners takes 10-15 working days. A pre-aligner or passive brace is made first so the aligners are confirmed to be a perfect fit. Next, custom made aligners are sent over to the patient. The aligners are changed every 2-4 weeks until the results are achieved.
