As SPAs have evolved and become more sophisticated, they have become more
useful in the management of more severe malocclusion. This is implicit in claims
made by both manufacturers and users. Published research does not support this.
Refinement and improvement in the design of the aligners is continuing but until
new research is presented we need to carefully select our cases for this type of
