How can more predictable finishing be achieved consistently with aligners in highly complex malocclusions? This aligner update covers a simple prescription with three differential supercorrections, dentofacial orthopedic applications with aligners, and six new aligner innovations built upon a scientific, physics-based foundation of aligner biomechanics. Here we categorize in a systemized manner the biomechanical concepts and supercorrections for aligners by applying the literature with extensive illustrations. We then complemented these principles with actual clinical treatments recruiting several other aligner experts.
