All-on-6 in Krakow: When Six Implants Are Better Than Four (2026)

All-on-4 is the industry standard, but for some patients All-on-6 is the clinically better answer. This guide explains when 6 implants beat 4, what it costs in Krakow, how HALDENT handles complex full-arch cases, and how to tell if your case actually needs All-on-6.

What is All-on-6 and how it differs from All-on-4

All-on-4 uses 4 implants at strategic angles, with the posterior implants tilted up to 45 degrees to avoid the sinus cavities and maximise bone contact. All-on-6 uses 6 implants, usually placed more vertically and distributed evenly across the arch. The additional 2 implants provide better load distribution, stronger anchorage under bite forces, and redundancy if one implant fails over the long term.

Both protocols anchor a fixed, non-removable full-arch bridge. Both allow immediate loading in most cases, meaning you leave the clinic with fixed teeth the same day as surgery. The choice between them is driven by anatomy, bite forces, and long-term planning, not marketing.

When All-on-6 is clinically indicated

• Lower bone density in the arch. The upper jaw has naturally softer bone than the lower jaw. When CBCT confirms reduced density, 6 implants spread the load and reduce per-implant stress.
• Bruxism (teeth grinding). Grinders generate bite forces well above normal. Six anchor points handle those loads better than four.
• Longer dental arches. Some patients have arches where 4 implants cannot comfortably support the full cantilevered span at the back of the mouth.
• Patients wanting maximum long-term security. If one implant ever fails with All-on-4, you have 3 left and the bridge is at risk. With All-on-6, you have 5 remaining and clinical margin to repair without remaking the full prosthesis.
• Complex cases where zygomatic implants are being considered. All-on-6 is often the step between standard All-on-4 and zygomatic protocols for patients with moderate upper-jaw bone loss.

When All-on-4 is still the right choice

• Adequate bone volume confirmed on CBCT. If the scan shows sufficient density and height, 4 implants placed to the Malo protocol deliver proven outcomes.
• Standard bite forces, no bruxism. Patients without grinding habits load implants within well-studied ranges.
• Budget-constrained cases where All-on-4 meets clinical requirements. Paying for 2 extra implants you do not clinically need is not better care, it is more expensive care.
• Professor Paulo Malo's original protocol specifically uses 4 implants. The clinical data behind All-on-4 is the most extensive body of evidence in implant dentistry, with 20+ year survival data.

All-on-4 vs All-on-6 cost comparison in Krakow (per arch, 2026)

The marginal cost of the 2 extra implants at Krakow prices is EUR 1,500-2,500, which is less than the price of a single implant in the UK. For any patient whose clinical profile genuinely requires All-on-6, the additional spend is the right investment.

Country cost comparison (All-on-6 per arch, zirconia)

A UK patient flying to Krakow for All-on-6 typically saves GBP 14,000-20,000 per arch even after flights, 7-day hotel, and the follow-up visit. For bilateral cases (both arches), savings reach GBP 30,000-40,000.

Material options for All-on-6

The same 3-tier material ladder applies whether you choose All-on-4 or All-on-6. The implants themselves are the same Nobel Biocare or Straumann titanium. The difference is the prosthesis cemented onto them.

• Acrylic hybrid: EUR 8,500-11,000 per arch. Acrylic teeth on a titanium framework. 3-7 year functional lifespan. Entry tier, fine as a long-term provisional.
• Titanium bar with composite: EUR 10,500-13,500 per arch. Milled titanium bar with high-strength composite teeth. 7-12 year lifespan. Mid tier, good aesthetic and durability balance.
• Monolithic zirconia: EUR 12,000-16,000 per arch. Single-piece milled zirconia. 15-20+ year lifespan when maintained. Highest aesthetic, chip-resistant, recommended if budget allows. HALDENT mills zirconia in-house at its Straumann-qualified lab.

HALDENT's case volume in complex full-arch

HALDENT performs both All-on-4 and All-on-6 as part of its 1,500+ annual patient volume at the Zabierzów clinic. Dr. Hubert Trzepatowski's 900+ personal All-on-4 cases and Malo Clinic certification extend to the full protocol family, including All-on-6 and All-on-X variations for patients with unusual anatomy.

Every full-arch case starts with a CBCT scan. The scan drives the decision between All-on-4 and All-on-6. If the bone is right for 4 implants, you get 4. If it requires 6, you get 6. The decision is clinical, not commercial, and that is the protocol discipline that separates Nobel Biocare Platinum Excellence Centers from clinics that upsell every case.

Two-visit treatment protocol

The All-on-6 protocol at HALDENT runs over two visits, separated by a 4-6 month osseointegration period.

Visit 1 (5-7 days)

• Day 1: Arrive at Krakow KRK airport, free HALDENT pickup to your hotel.
• Day 2: Consultation, CBCT scan, final treatment plan confirmed with Dr. Trzepatowski or the assigned lead surgeon.
• Day 3: Surgery. 6 Nobel Biocare implants placed under local anaesthetic, IV sedation offered for anxious patients. Immediate provisional fixed prosthesis placed the same day.
• Days 4-5: Recovery, post-op review visit, Old Town at a gentle pace. Soft food diet.
• Day 6-7: Final check, fly home with the provisional bridge.

Visit 2 (3-5 days, 4-6 months later)

• Final monolithic zirconia prosthesis fabricated in HALDENT's in-house Straumann-qualified lab using digital impressions taken at the start of the visit.
• Try-in, occlusion check, shade confirmation.
• Final cementation or screw-retention.
• Fly home with the permanent prosthesis, full chewing function restored.

Zygomatic implants as the next step

For patients whose upper jaw bone is too severely resorbed for All-on-6, zygomatic implants anchor into the zygomatic (cheek) bone above the sinus. This avoids the need for major sinus lifts or bone grafts and delivers immediate loading in most cases. HALDENT handles zygomatic cases where clinically indicated, typically in combination with 2-4 standard anterior implants (the "zygoma quad" or hybrid zygoma protocols).

Zygomatic implants cost EUR 3,000-5,000 per implant at Krakow clinics, versus EUR 8,000-12,000 per implant in UK private practice. A full zygomatic-hybrid reconstruction in Krakow runs EUR 18,000-25,000 per arch, still less than half of UK pricing.

Aftercare

• Water flosser essential. Floss daily under the prosthesis with a Waterpik or similar. This is non-negotiable for long-term implant health.
• Soft toothbrush only. Electric soft-head toothbrush twice daily.
• Annual professional clean. At HALDENT if returning to Krakow, otherwise at a competent hygienist locally. Ask them to use plastic-tipped instruments, not metal scalers, around the implants.
• No hard foods for the first 2 weeks after surgery while osseointegration begins.
• Permanent zirconia prosthesis allows hard foods once the final bridge is placed. Apples, steak, nuts all fine.
• Night guard if you grind. Even with All-on-6, a custom night guard protects the prosthesis from bruxism-related wear.

Red flags for All-on-6 offers

• Same price as All-on-4. Any clinic that offers All-on-6 at the same price as All-on-4 is quietly downgrading material tier, surgeon experience, or implant brand. There is no free lunch on 2 extra Nobel Biocare or Straumann implants at EUR 750-1,000 each wholesale.
• All-on-6 pushed on every case. Any clinic that recommends All-on-6 without showing you the CBCT and explaining the specific anatomical reason is upselling. Ask to see the scan.
• No CBCT before the quote. A full-arch quote based on a panoramic X-ray alone is a commercial quote, not a clinical plan.
• Generic implant brand. If the clinic will not name the specific implant brand and system in writing, walk away. Nobel Biocare and Straumann have full international warranty networks, off-brand systems often do not.
• No named surgeon. You want to know who is holding the drill and their full-arch case volume.

FAQ

When is All-on-6 better than All-on-4?

All-on-6 is clinically better when CBCT shows reduced bone density (especially in the upper jaw), when the patient is a known bruxist, when the dental arch is unusually long, or when the patient wants redundancy in case one implant fails over the decades ahead. For standard anatomy with good bone and normal bite forces, All-on-4 remains the proven standard backed by Professor Malo's 20+ year data.

How much more does All-on-6 cost than All-on-4 in Krakow?

The price difference at Krakow clinics is EUR 2,000-2,500 for acrylic and EUR 1,500-2,500 for zirconia per arch. At HALDENT, zirconia All-on-6 runs EUR 12,000-16,000 per arch versus EUR 10,500-13,500 for zirconia All-on-4. The 2 extra implants are the main cost driver, the prosthesis is similar in price because it is fabricated to span the same arch.

Does HALDENT perform All-on-6 cases?

Yes. HALDENT performs All-on-6 as part of its full-arch case load, which exceeds 900 personal cases for Dr. Trzepatowski across the All-on-X protocol family. HALDENT is a Nobel Biocare Platinum Excellence Center and Poland's only Malo Clinic certified All-on-4 trainer, so the team is trained on the full protocol spectrum from standard All-on-4 through All-on-6 to zygomatic implants.

Can I have All-on-4 on one arch and All-on-6 on the other?

Yes, and this is actually a common clinical scenario. The upper jaw often has softer bone than the lower, so a mixed protocol of All-on-6 upper and All-on-4 lower is routinely planned. HALDENT will present the mixed-protocol quote if CBCT indicates it. Typical combined cost at HALDENT is EUR 22,500-29,500 for both arches in zirconia.

What warranty does HALDENT provide on All-on-6?

HALDENT provides a lifetime warranty on the implant bodies directly to the patient. This is given by HALDENT, not by any third party or marketplace. The prosthesis itself carries a separate warranty of 5-15 years depending on the material tier. Any warranty work during follow-up visits to Krakow is covered under the direct HALDENT guarantee.
