Transparent aligner sheet. UNIQ pd offers an innovative solution for treatments with aligners by achieving maximum effect with a single layer. Unlike many multilayer sheets, UNIQ pd permanently withstands the forces generated throughout the treatment without loss of stability. The enhanced characteristics of the UNIQ pd material allow for less pressure to be exerted over an extended period compared to conventional single-layer aligner materials. Thanks to its gentle initial forces and constant restorative forces, it also provides significantly greater comfort during use. As a result, teeth move more smoothly and efficiently, while the patient enjoys increased comfort.
