Clear Aligner Residency Program

Learn how to select clear aligner cases, with tips for your first case, and examples of indications, focusing on patient selection, case complexity, and doctor's experience.

Identify good candidates for clear aligners by prioritizing patient compliance, removable appliances, oral hygiene, and realistic expectations, while educating patients about 22 hours daily wear and 1–2 week aligner changes.

Explore case complexity in patient selection by linking malocclusion severity and tooth movements to aligner treatment predictability. Set realistic objectives to improve tracking and treatment outcomes.

match liner cases to the doctor’s experience, guiding beginners to mild cases and experts to advanced extractions, crowding, and crossbites, with case-by-case assessments.

Discover the full spectrum of movements achievable with clear aligners, from mild class I cases to complex needs requiring extractions and auxiliaries. Emphasizes patient selection, compliance, and advanced training.

Understand the records workflow and case lifecycle for clear aligner treatment, from orthodontic assessment and records submission to treatment setups, review, manufacturing, and shipping.

Conduct a comprehensive orthodontic assessment through detailed history, records, and full intraoral and extraoral examination to craft an effective treatment plan for clear aligners, emphasizing motivation and compliance.

Perform an extraoral exam to assess facial morphology, symmetry, smile line, lip competence, and swallowing; then evaluate relationships (canine molar incisor), overjet, overbite, crowding, and caries, addressing pathology before treatment.

Identify the records required to submit a case: extra-oral and intra-oral photos, impressions or scans, x-rays, and the submission form, plus three extra-oral and five intra-oral views.

Capture eight orthodontic photos: three extraoral and five intraoral, for records, with a dslr, 90–100 mm macro lens, ring flash, retractors, and an occlusal mirror on a white background.

Provide quality impressions or intraoral scans with flawless margins and full-arch coverage; record both arches with a bite registry, noting that impressions are more accurate, comfortable, and faster.

Take full-arch impressions with polyvinyl siloxane putty and light wash in sized trays, inspect for defects, and capture centric occlusion bite with silicone bite registration material, then disinfect and ship.

Learn to perform intraoral scans as an alternative to conventional impressions, with proper scanner setup and defogging. Capture occlusal, lingual, and buccal surfaces, interproximal anatomy, and verify margins and bite.

Submit panoramic x-rays for general findings or lateral cephalogram for planning, then complete the treatment submission form with chief complaint, treatment summary, wear cycles, and extractions or interproximal reduction.

Attachments are composite extensions on tooth surfaces that provide a flat active surface for the aligner to push against, enabling movements; clinicians customize shape, size, and position, including bite ramps.

Explore active and passive attachments for clear aligners, including horizontal and vertical bevelled rectangles, extrusion, rotational, and root-control designs that enable rotations, extrusion, and mesiodistal movements with improved retention.

Explore attachments and bite ramps in clear aligners, improving aesthetics, disoccluding posterior teeth in deep bite, and intruding anterior teeth with armamentarium for placement.

Learn to place attachments on aligners using tooth-colored composite, following a step-by-step protocol from template fitting and etching to bonding, curing, and limiting to three teeth per quadrant.

Explore clear aligner biomechanics, including translation, crown tipping torque, rotation, intrusion, and extrusion, and how sequential thermoformed trays push teeth, with attachments aiding difficult rotations and 3D simulations guiding treatment.

Understand buccolingual translation, including proclamation and retraction for anterior teeth, and expansion or constriction for posterior teeth. Plan mesiodistal movements—medialization and distalization—with attachments to counteract tipping and manage treatment duration.

Explore crown tipping and buccolingual torque in clear aligner therapy, using root control attachments and torque enhancers to apply two-point forces and achieve or preserve incisor torque.

Explore how rotations, intrusions, and extrusions shape treatment with clear aligners, detailing when attachments and bite ramps are needed to achieve predictable tooth movement.

Define interproximal reduction, review its indications and contraindications, explain safety, show how to read ipr information, and introduce performing ipr with essential armamentarium.

Explore interproximal reduction on rectangular, triangular, and barrel teeth to remove black triangles and incisal embrasures, preserve arch shape, and consider mixed crowding solutions: expansion, proclamation, distalization, stripping, and extraction.

Apply four IPR principles—accuracy, timing, measurement and tracking, and patient safety—to ensure precise enamel removal, accessible contact points, safe cheek and tongue retraction, and adherence to the IPR sheet.

Perform interdental reduction (IPR) to create space for crowded teeth by removing enamel at mesio-distal contacts, using interdental strips, diamond discs, or burs, check gauges, polish and apply fluoride varnish.

Monitor each case by checking aligner fit, attachments, and IPR per sheet; evaluate progress against the treatment setup and use occlusal comparisons to identify on-track or poor-tracking patients.

Assess progress by evaluating tracking quality of aligners—perfect, good, or bad—and troubleshoot causes such as patient compliance, attachments, and occlusal issues to keep treatment on track.

Identify and address patient non-compliance and tight contacts by motivating wear of aligners, using warm-water rinses, floss checks, and chewies to restore proper tracking.

Troubleshoot attachments to prevent loss of tracking by using correct attachments for difficult movements, applying chewies for fit, and considering mid-course adjustments, replacements, or impressions for active versus passive attachments.

Troubleshoot challenging movements and occlusal discrepancies in clear aligners by allowing time for movement, using auxiliaries, and managing tissue impingement, third molar interference, and bite settling with retainers or elastics.

Identify external factors such as calculus buildup and restorative work that disrupt aligner fitting and tracking, and address chipped teeth, residual spaces, black triangles, IPR, and refinements to optimize movement.
