1 | Why Adult Class II Is Tricky

Growth is over; only camouflage (dento-alveolar compensation) or orthognathic surgery remain. Class II in adults ≈ 4 % prevalence yet 30 % of surgical jaw cases.

2 | Diagnostic Cut-offs

Parameter	Camouflage OK	Surgery Preferable
ANB	≥ 4°	≥ 6°
Wits	≤ +2 mm	≥ +4 mm
Mandibular plane	Low/normal	High-angle, open bite
Overjet	≤ 6 mm	≥ 8 mm
Incisor decomp needed	≤ 10°	> 10°

Borderline? Do a “spoon test”: if lower lip falls ≥ 3 mm behind E-line, surgery gives better profile.

3 | Camouflage Toolbox (2025 Updates)

TAD-Supported Distalisation — 3.5 mm average bodily distal move; 70 % success avoiding extractions.
Upper First-Premolar Extractions — Creates space for incisor retraction; preserve molar Class I.
Clear Aligners with Power-Ridges — Mild Class II ≤ 4 mm corrected in 15–18 months.
Elastics + TAD Anchorage — 3 oz Class II elastics anchored to miniscrews minimise lower incisor flare.

4 | Surgical Options

Procedure	Typical Move	Profile Gain	Recovery
BSSO Advancement	5–8 mm mandible	Improves chin projection	4–6 wk soft diet
2-Jaw (Le Fort I + BSSO)	3–5 mm maxillary setback + 5–8 mm mandible	Best occlusion & airway	6 wk splint
Surgery-First Protocol	Decomp after cut	Rapid profile	Needs 3-D planning

Patients report 92–98 % satisfaction for bimax cases vs 55–70 % for camouflage when profile is concern.

5 | Comparative Outcomes

Outcome	Camouflage	Surgery
Overjet change	+6 mm → +1 mm	+7 mm → 0 mm
Post-Tx ANB	–1° avg	–4°
Profile (G-Sn-Pg angle)	−1°	−6°
5-yr relapse > 1 mm	18 %	6 %
Treatment time	18–24 mo	14–20 mo (incl. surgery)
Patient satisfaction	58 % “very happy”	94 %

6 | Risks & Complications

Risk	Camouflage	Surgery
Root resorption	12–22 %	Rare
Periodontal fenestration	If > 10° retroclination	None
Paresthesia	None	5–10 % temp, 1 % perm
Relapse	Anchorage loss	Condylar sag
Cost	$$	$$$$
Downtime	0 days	14–21 days off work

7 | Cost & Timeline Snapshot

Region	Camouflage	Surgery Package
U.S.	US $4 500 – 7 000	US $25 000 – 35 000
U.K.	£3 500 – 6 000	£16 000 – 26 000
Insurance	Rarely	Often if airway/TMJ issues

8 | Decision Flowchart

ANB ≥ 6° or Wits ≥ +4 mm? → Surgery consult.
Overjet ≤ 6 mm & patient cost-averse? → Camouflage trial.
Incisor decomp > 10° needed? → Surgery.
Profile acceptable & airway fine? → Camouflage likely satisfies.

9 | Case Study — 30-Year-Old Male

Baseline: ANB 7°, overjet 8 mm, convex profile.
Plan: TAD distalisation attempt; failed to reach Class I after 6 mo. Switched to 2-jaw surgery.
Outcome: ANB 0°, profile straight. Satisfaction 10/10; paraesthesia resolved by 6 mo.

Lesson: borderline skeletal II often tips towards surgery for stability and aesthetics.

10 | FAQ

Can miniscrews alone correct severe skeletal II?
No; distal move plateau ≈ 3.5 mm. Severe (> 8 mm) needs surgery.

Is surgery more painful?
Pain peaks Day 1, VAS ~4/10; camouflage peaks Day 3, VAS ~3/10. Swelling, not pain, is main downtime.

Are there age limits?
Healthy adults up to 60 yrs have similar bone healing; medical clearance is key.

11 | Conclusion & Next Steps

Camouflage with TADs can fix mild Adult Class II quickly and cheaply—but surgery offers superior profile and long-term stability for moderate-to-severe cases. Use the decision flowchart, budget realities, and patient priorities to choose wisely.
