Simpli5 clear aligner system straightens and realigns the teeth using precise 3-D imaging technology. It consists of five sets of aligners that are invisible and lightweight. The procedure begins with taking a dental impression of the patient’s teeth. The impressions are scanned to produce 3D models. Five virtually invisible plastic aligners are then manufactured in 3-4 weeks. The first aligner is fitted in the patient’s mouth. All aligners are worn in succession for 3-4 weeks at a time.
