2. Key Differences (Easy-to-Read Comparison Table + Bullet Points)

3. Material Breakdown (EEAT: Professional Terms + Authoritative Sources)

• Clear Aligner Materials:

  • PETG (Polyethylene Terephthalate Glycol): High elasticity for precise tooth movement.

  • Multilayer PC (Polycarbonate): Scratch-resistant, long-term wear (e.g., Invisalign’s patented material).

  • Medical Certification: Must meet FDA/CE medical device standards.

• Clear Retainer Materials:

  • Essix Acrylic Resin: High clarity, stain-resistant.

  • Rigid PVP: Extra durability for nighttime wear (e.g., Vivera retainers).

4. FAQs (Addressing User Concerns)

• Q: Can I use a retainer instead of aligners?
  → No! Retainers can’t move teeth—forcing them may cause root damage.

• Q: Are cleaning methods the same?
  → Aligners need deep cleaning (ultrasonic cleaner); retainers can use water + soft brush.
