When is All-on-6 recommended over All-on-4?

Larger mandibles, heavier bite forces, prior implant failures, or where the surgeon judges more distributed loading will improve long-term stability. CBCT and clinical assessment decide — not patient preference.

Does All-on-6 cost more than All-on-4?

Yes. Two additional fixtures, abutments, and surgical time add GBP 1,594 per arch at the Osstem tier. See the full comparison table on this page.

Can All-on-6 be done in one trip?

Provisional teeth may be fitted the same day in selected cases where primary stability is confirmed. A final reinforced bridge almost always needs a second trip after osseointegration.

Is All-on-6 safer than All-on-4?

Neither is universally safer. Proper CBCT planning, sterile surgical protocol, and patient compliance with aftercare matter more than the number of implants. A well-planned All-on-4 outperforms a poorly planned All-on-6.

What happens if one implant fails in an All-on-6?

Five remaining fixtures can often continue to support the bridge while a replacement is assessed. This is one reason some surgeons prefer six implants — it provides a margin if one fixture does not integrate.

How do I know which arch system I need?

Submit your OPG or CBCT at /free-quote/. Your written plan will state whether All-on-4 or All-on-6 is recommended based on bone anatomy and bite analysis.

All-on-6 dental implants from GBP 5,217 | Picasso Vietnam

All-on-6 full arch implants for UK patients - six implants per arch, GBP pricing across three brands, comparison with All-on-4, and candidacy at Picasso Dental Clinic Vietnam.

All-on-6 at Picasso Dental Clinic starts at GBP 5,217 per arch with Osstem and reaches GBP 8,696 with Nobel Biocare or Straumann - compared with GBP 14,516–GBP 24,194 per arch at UK private clinics - using six implants rather than four for greater distribution across larger jaws or heavier bite forces.

All-on-6 at Picasso Dental Clinic starts at GBP 5,217 per arch with Osstem implants. The same procedure at a UK private clinic typically costs GBP 14,516–GBP 24,194 per arch. Six implants per arch give more distributed loading than four, which some surgeons prefer for larger mandibles, heavier bites, or patients with a history of implant complications.

This page explains when All-on-6 is chosen over All-on-4, what the GBP prices look like across all three brand tiers, and what the trip structure involves for UK patients.

All-on-4 vs All-on-6 — the engineering difference

	All-on-4	All-on-6
Implants per arch	4	6
Rear implant angle	Angled to avoid sinus or nerve	Posterior pairs allow straighter placement
Force distribution	Concentrated on four points	Spread across six points
Bone requirements	Moderate — angling compensates	Slightly more posterior bone needed
Best case	Standard edentulous arch	Larger jaw, heavy bite, or higher load demand
Picasso price (Osstem)	GBP 3,623	GBP 5,217
Picasso price (Nobel/Straumann)	GBP 6,377	GBP 8,696

Neither approach is inherently better. The right choice is determined by CBCT bone analysis, bite force assessment, and the implant surgeon’s clinical judgment. Picasso will not recommend All-on-6 as a default upgrade — the CBCT findings drive the recommendation.

GBP price table — three implant tiers

Implant brand	All-on-6 per arch (GBP)
Osstem (South Korea)	GBP 5,217
ETK / Neodent	GBP 6,087
Nobel Biocare / Straumann	GBP 8,696

Prices correct as at May 2026. Each quote names the brand and fixture reference. Prosthetic bridge add-ons are the same as All-on-4:

Prosthetic add-on	GBP
Acrylic full-arch bridge	GBP 1,449
Titanium full-arch bar	GBP 2,029
BioHPP full-arch bar	GBP 2,029

How All-on-6 compares to UK private costs

At UK private clinics, All-on-6 per arch typically starts at GBP 14,516 for entry-level systems and rises to GBP 19,355–GBP 24,194 with Nobel or Straumann. For two arches, UK patients frequently face GBP 29,032–GBP 48,387 total.

The Picasso GBP 5,217 starting point represents a significant difference even after two return flights (GBP 580–GBP 870 from London), accommodation, and time off work.

Who is a candidate for All-on-6

Likely candidate	May need different approach
Full arch edentulism with larger mandible	Severe maxillary atrophy — zygomatic implants may be better
Heavy bite force (bruxist with management plan)	Uncontrolled bruxism — prosthetic failure risk is high
Previous All-on-4 failure in one fixture	Active periodontal disease requiring treatment first
Surgeon recommendation based on CBCT biomechanics	Uncontrolled diabetes (HbA1c above 7.5)
Non-smoker or reduced smoking	Cannot commit to two trips with healing interval

Clinical team

Dr. Tran Thanh Phong leads full-arch implant surgery at Picasso. He has performed over 1,000 All-on-4 and All-on-6 cases and has been a Nobel Biocare clinical representative in Vietnam since 2007. He has placed over 400 zygomatic implants since 2017 for patients where standard arch protocols are not appropriate. Full credentials at /safety/dentist-credentials/.

The surgical protocol

Before you fly:

Submit OPG or CBCT plus medical history via /free-quote/
Receive written GBP plan confirming All-on-6 recommendation, implant brand, and trip structure
Any bone grafting needs flagged at this stage — no surgery-day surprises

Trip 1 (allow 8–12 days for All-on-6):

CBCT confirmed on arrival; final plan locked
Extractions of remaining teeth if required
Six implant fixtures placed under local anaesthesia; sedation available
Provisional bridge or healing caps fitted based on primary stability findings
Soft diet protocol, emergency contact, written aftercare

Healing at home (4–6 months):

Osseointegration confirmed with X-ray at home or on return
UK hygienist can maintain oral health — brief your UK dentist with Picasso records

Trip 2 (allow 5–7 days):

Integration confirmed; digital scan or impression taken
Final bridge fabricated in lab (3–5 working days)
Bridge seated, adjusted, and warranty documentation issued

Bone grafting and the All-on-6 price

If CBCT shows bone loss that affects placement, grafting is disclosed in the written plan before you book. All-on-6 requires adequate posterior bone for straight-placed rear fixtures; where this is limited, the surgeon may recommend angling implants (moving toward an All-on-4 design) or sinus augmentation.

Graft type	GBP
Sinus augmentation — closed	GBP 203
Sinus augmentation — open	GBP 406
Block graft	GBP 290

Immediate loading and delayed loading

Protocol	When it applies
Provisional teeth same day	Primary stability confirmed on CBCT; bone quality adequate
Healing caps, delayed bridge	Bone quality borderline; recently grafted sites; surgeon’s clinical judgment

Immediate loading is determined by surgical findings on the day, not booked in advance as a feature.

After you return to the UK

Your UK dentist should see you within 3 months of the final bridge fitting for:

Periapical or panoramic X-ray to verify bone levels around all six fixtures
Professional implant hygiene (different technique from natural tooth cleaning)
Bite assessment and any bridge screw torque check

Bring your implant passport, brand names, fixture references, and abutment torque specifications. Guidance for your UK dentist at /follow-up-care-uk/.

Who should stay local or delay

Active gum disease or untreated periodontitis — treat first
Uncontrolled systemic health conditions — get cleared by GP
Heavy smokers — risk of non-integration is materially higher; reduce before surgery
Patients needing concurrent orthodontic and surgical sequencing
Anyone unable to commit to two trips and the healing window between them

We tell you this before you book flights.
