    Abstract: Background: Orthodontic relapse tendency occurs 33–90 per cent after at least 10 years post-treatment. Orthodontic Relapsing is the return, following orthodontic correction, at the end of treatment. Relapse, a return to the original teeth position, caused by periodontal, occlusal, soft tissue factor and growth. Nanopowder Stichopus hermanii have va... Show More
