hy Fewer Refinements Start With the Mechanics, Not Software | Orthodontics In Interview | Enzo Pasciuti
“If you don’t understand fixed appliance mechanics, you won’t truly understand aligner mechanics.”
“Don’t judge your aligner cases on the computer. Judge them clinically.”
“Predictability isn’t about using fewer aligners, it’s about respecting biomechanics and biology.”
Why do some orthodontists achieve consistently lower refinement rates with aligners.Joining me is Enzo Pasciuti, shedding light on key mechanics, planning philosophies and clinical pearls that have helped him achieve predictability and reducing refinements, whilst acknowledging challenging aligner mechanics, increasing the number of aligners, and rigidly adhering to biomechanical principles of all tooth movement.
We discuss the importance of clinically assessing every refinement, and why orthodontists should never rely solely on virtual treatment planning. Enzo also explains how attachments, passive aligners, staged treatment planning, and Dental Monitoring can significantly improve clinical outcomes.
We also explore instability with aligners, a frequently overlooked outcome when unplanned, common mistakes clinicians make with aligners, and why every orthodontist should first master fixed appliance mechanics before expecting excellence with clear aligners.

Key Summaries
Key Summary 1
Planning refinements from clinical chairside assessment, not the digital model More attachments rather than fewer Using dental monitoring to track fit, but not to plan refinementSa gittal correction via Class II elastics rather than aligner count, using passive aligners (6 per set) to finish Class II correction, order more only if needed
Stage complex movements, prioritise select movement and re-scan for subsequent movements
Key Summary 2
Relative vs. true movement for class 2 correction, favourable for rotation and distal tipping, but true translation beyond ~2.5mm needs skeletal anchorage Slowing movement down by 30% to increase predictability, will increase aligners Increase trim line to increase the force levels, especially for root movement Do not combine difficult movements, stage, e.g. align then intrude or torque
9 month stabilization:
Month 1-3 Full-time aligner
Month 4-6 Reduced by 1 hour/week
Month 7-9 10hrs/day
Aligner re-treatment cases – manage with fixed appliances
