1 | Market snapshot
- Lingual demand +37 % YoY; new low-profile brackets & robot-bent wires made the difference.
- Aligners still dominate (73 % share) due to DTC marketing, but complex cases shifting lingual.
2 | Hardware & biomechanics
| Feature | Clear Aligners | Lingual Braces |
|---|---|---|
| Force delivery | Plastic deformation & attachments | Low-friction NiTi & custom torque |
| Range | 0–4 mm per tray | Unlimited with wire adjustments |
| Auxiliaries | Elastics, TADs | Elastics, TADs, sectional lingual |
3 | Cost breakdown 2025
| Region | Aligners (full) | Lingual (Incognito/2D) | Δ |
|---|---|---|---|
| U.S. | $4 800 – $8 500 | $7 500 – $11 000 | +38 % |
| U.K. | £3 500 – £5 800 | £6 000 – £8 800 | +49 % |

Insurance covers both if medically necessary; lifetime ortho caps apply equally.
4 | Clinical outcomes (meta-analysis 2023–24)
| Metric | Aligners | Lingual | p-value |
|---|---|---|---|
| Avg duration | 12.1 mo | 15.3 mo | 0.04 |
| Refinement sets | 1.2 | 0.5 | 0.02 |
| Final Irregularity Index | 0.7 mm | 0.5 mm | ns |
| Relapse @ 3 yrs > 1 mm | 16 % | 11 % | 0.03 |
Lingual excels in torque & incisor control; aligners win on speed.
5 | Speech, comfort & lifestyle
| Factor | Aligners | Lingual |
|---|---|---|
| Lisp days | 0–3 | 5–10 |
| Ulcer incidence | 8 % | 22 % (first 4 wks) |
| Diet limits | Remove to eat | Sticky foods avoided |
| Oral hygiene | Remove to brush | Superfloss & water-flosser |
| Sports mouth-guard | Easy | Custom guard needed |
Pain VAS Day 1: 3.7 (aligner) vs 4.3 (lingual).
6 | Practice economics
| Line | Aligners | Lingual |
|---|---|---|
| Lab fee | $250–450 | $800–1 200 |
| Avg chair-time/case | 4.2 h | 6.8 h |
| Case fee mark-up | 3.2× lab | 2.4× lab |
| ROI @ 400 pts/yr | High (volume) | Niche high-fee |
Lingual profitable in boutique clinics; aligners scale in volume practices.
7 | Red-flag checklist
Aligners fail when…
❌ Crowding > 8 mm per arch
❌ Severe deep-bite with gummy smile
❌ Rotations > 40° without attachments
Lingual fails when…
❌ Tiny lower arch (< 26 mm intercanine)
❌ Patient cannot tolerate lisp (singers, broadcasters)
❌ Low budget or poor oral hygiene
8 | Decision matrix
| Priority | Pick Aligners | Pick Lingual |
|---|---|---|
| Speed | ✔ | — |
| Aesthetics (zero visibility) | — | ✔ |
| Complex torque / extraction | — | ✔ |
| Speech-critical job | ✔ | — |
| Tight budget | ✔ | — |
| Severe crowding > 8 mm | — | ✔ |
9 | FAQ
Can I switch mid-treatment?
Yes—aligners → lingual possible; reverse harder due attachment removal.
Which hurts more?
Lingual slightly; peaks Day 2, fades by Day 7.
Is lingual harder to clean?
Yes—water-flosser + interdental brush mandatory.
