Orthodontic Aligners Course

Lesson 1 • History and Evolution of Aligners

Traces aligner development from removable plates to precision CAD/CAM systems. Contextualizes modern aligner therapy within broader orthodontic history.

Lesson 2 • Patient Selection and Case Screening

Defines clinical criteria for aligner candidacy including skeletal, dental, and compliance factors. Builds systematic screening skills to avoid poor case selection.

Lesson 3 • Biology of Tooth Movement

Covers periodontal ligament remodeling, bone turnover, and force thresholds. Links biological principles directly to aligner staging and force delivery.

Lesson 4 • Aligner Materials and Properties

Examines thermoplastic polymers, thickness variations, and material degradation. Enables informed material selection based on clinical requirements.

Lesson 1 • Problem List and Goal Setting

Structures findings into prioritized problem lists and measurable treatment goals. Bridges diagnosis to actionable aligner staging decisions.

Lesson 2 • Treatment Planning for Common Malocclusions

Applies diagnostic skills to Class I crowding, spacing, Class II, and Class III cases. Develops case-specific planning strategies using aligner mechanics.

Lesson 3 • Comprehensive Orthodontic Records

Details required records including photographs, radiographs, and digital scans. Establishes record-taking standards that underpin accurate diagnosis.

Lesson 4 • Dental and Occlusal Analysis

Evaluates arch length discrepancy, Bolton analysis, and occlusal relationships. Translates dental findings into specific aligner movement prescriptions.

Lesson 1 • Digital Model Segmentation

Teaches tooth segmentation, root estimation, and gingival margin trimming in software. Precise segmentation directly determines movement accuracy in the setup.

Lesson 2 • Treatment Setup and Staging

Guides creation of staged tooth movements, step sequencing, and overcorrection planning. Staging decisions determine clinical efficiency and predictability.

Lesson 3 • Intraoral Scanning Techniques

Covers scanner operation, scanning sequences, and common error correction. Accurate scans are the foundation of all downstream digital planning.

Lesson 4 • Attachment Design in Software

Explains attachment placement logic, shape selection, and software placement tools. Proper attachment design is critical for achieving planned tooth movements.

Lesson 1 • Interproximal Reduction Integration

Explains IPR rationale, sequencing within aligner stages, and safe reduction limits. IPR is a primary space-creation tool that must be precisely timed.

Lesson 2 • Auxiliaries: Elastics and Buttons

Covers elastic hooks, precision cuts, and button placement for Class II/III correction. Auxiliaries extend aligner capability beyond plastic mechanics alone.

Lesson 3 • Aligner Trimline and Cutout Design

Examines scalloped versus straight trimlines and cutout effects on force delivery. Trimline design influences retention, comfort, and biomechanical efficiency.

Lesson 4 • Attachment Placement and Bonding

Details clinical bonding technique, isolation, and composite selection for attachments. Proper bonding ensures attachment retention throughout treatment.

Lesson 1 • Molar Distalization Techniques

Details sequential distalization staging, anchorage management, and auxiliary support. Molar distalization is a key Class II correction strategy with aligners.

Lesson 2 • Vertical Movement: Intrusion and Extrusion

Explains attachment designs and staging for reliable intrusion and extrusion. Vertical movements are critical for open bite and deep bite correction.

Lesson 3 • Rotation and Derotation Strategies

Covers rotation mechanics, attachment placement for derotation, and overcorrection staging. Rotations are frequently under-expressed and require specific compensations.

Lesson 4 • Managing Extraction Cases

Applies aligner mechanics to space closure, anchorage control, and torque in extraction cases. Extraction cases demand precise staging and attachment planning.

Lesson 1 • Refinements and Mid-Course Corrections

Guides timing, scanning, and planning of refinement phases. Refinements are a normal part of aligner therapy requiring systematic clinical judgment.

Lesson 2 • Compliance Strategies and Motivation

Applies behavioral techniques to improve wear time and patient engagement. Compliance directly determines treatment outcomes in aligner therapy.

Lesson 3 • Aligner Delivery Appointment

Covers bonding attachments, fitting aligners, and patient education at delivery. A thorough delivery appointment sets the foundation for treatment success.

Lesson 4 • Recall and Progress Monitoring

Defines recall intervals, tracking methods, and clinical assessment at each visit. Systematic monitoring detects tracking issues before they compound.

Lesson 1 • Long-Term Retention Monitoring

Establishes recall schedules, retainer assessment criteria, and patient re-engagement. Ongoing monitoring protects treatment investment and patient satisfaction.

Lesson 2 • Retention Appliance Selection

Compares fixed lingual retainers, vacuum-formed retainers, and hybrid options. Retention selection must match individual relapse risk and patient compliance.

Lesson 3 • Biological Basis of Relapse

Explains periodontal fiber reorganization, growth, and occlusal forces driving relapse. Understanding relapse biology informs retention duration and design.

Lesson 4 • Debonding Attachments and Cleanup

Details safe attachment removal, composite cleanup, and enamel surface restoration. Efficient debonding protects enamel and ensures a polished final result.

Lesson 1 • Orthognathic Surgery and Aligner Coordination

Covers pre-surgical decompensation, surgical wafer planning, and post-surgical finishing. Aligner-surgery coordination requires precise sequencing and team communication.

Lesson 2 • Periodontal Considerations in Complex Cases

Addresses aligner use in patients with bone loss, recession, and post-perio treatment. Periodontal status fundamentally alters force application and movement planning.

Lesson 3 • Restorative and Implant Coordination

Plans aligner treatment around existing restorations, implants, and prosthetic goals. Restorative coordination prevents irreversible conflicts between disciplines.

Lesson 4 • Aligner-Adjunct Therapy Integration

Combines aligners with TADs, expanders, and functional appliances for enhanced outcomes. Adjuncts expand the scope of aligner therapy beyond plastic mechanics.
