Rigid “never extract” and “always extract” philosophies both fail patients: one leaves severe crowding over-expanded and unstable, the other flattens faces that should never have lost a premolar. And once the space is open, uncontrolled retraction mechanics can undo even a correct decision. Mastering Extractions in Orthodontics replaces dogma with a decision hierarchy: face first, then occlusion, then cephalometrics. Prof. Kleber Meireles teaches systematic facial evaluation — convexity, nasolabial angle, lip protrusion, dental exposure in profile and frontal view — as the primary guide for whether a case benefits from extraction, expansion, distalization or stripping. Then he covers the execution: biomechanics and torque control during retraction with and without extraction, anchorage management including mini-implants, choosing the right tooth to extract based on prognosis, and the correct sequencing of mechanics — transverse, then vertical, then sagittal. What's inside — 10 clinical lessons covering • When extraction is advisable, avoidable, and specifically beneficial for the patient • The decision hierarchy: face first (profile and frontal), then occlusion, then cephalometrics • Systematic facial evaluation: convexity, nasolabial angle, lip protrusion, dental exposure • Correcting negative tooth-bone discrepancy — extraction vs expansion vs distalization vs stripping, and the limits of each (including buccal resorption from over-expansion) • Biomechanics and torque control during retraction, with and without extraction • Anchorage principles and management, including skeletal anchorage with mini-implants • Choosing the appropriate tooth for extraction based on case specifics, prognosis and mechanical goals • Sequencing orthodontic mechanics: transverse, vertical, sagittal • Class II and Class III strategies by magnitude and growth potential; managing open bite with extraction mechanics; recognizing when orthognathic surgery is the better option • Timing of extraction relative to retraction, lower-arch cautions, risks of asymmetric extractions, the role of stripping, and digital setups to predict outcomesWho this course is for: orthodontists and residents who want technically sound, patient-centered extraction decisions instead of inherited rules — especially those managing severe crowding, Class II, Class III and open bite cases where the extraction question keeps coming back. It is not for clinicians committed to a fixed “never” or “always” philosophy, and it does not cover loop and bend fabrication in depth (that belongs to the biomechanics courses). 15-day money-back guarantee. Run your next borderline case through the facial decision hierarchy — if it does not make the extraction call clearer, request a full refund within 15 days. Prof. Kleber Meireles has taught 700+ students across 131 countries, with treatments that used to take 4–5 years resolved in under 2 — because the right diagnosis makes the mechanics simpler.
