Full arch implants: choosing between 4 and 6

All-on-4 vs All-on-6: The Differences and Which One Suits You

The main difference is the number of implants: All-on-4 holds a complete bridge on four implants per jaw, All-on-6 on six. All-on-4 needs no bone grafting or sinus lift, heals faster and costs less. All-on-6 is more stable, spreads chewing force better and tolerates losing one implant, but costs more and needs more careful cleaning.

If you have lost most or all of your teeth in one jaw, you have probably come across both options. They look the same in your mouth and they are both fixed. The number of implants changes the bone you need, the stability, the cleaning and the cost.

Find out which one suits me

  • Your X-ray shows whether your jaw has bone for four or six implants, with a written quote before you book a flight
  • More than one treatment plan, so you can compare 4 and 6 implants side by side
  • Every Alpha Bio or Nobel Biocare implant, four or six, guaranteed for life (the product)
text of All-on-4-vs-All-on-6

What is the difference between All-on-4 and All-on-6?

In “All-on” treatment, the dentist places a complete bridge or denture on a set number of implants, typically 4 or 6, rarely 2, 8 or 10. The implants are made of bio-friendly titanium. However, if you have a metal allergy or prefer a completely metal-free solution, zirconia implants may also be an option. The more implants support the bridge, the stronger and more stable it is, and the more evenly the pressure of chewing is spread. So the more implants you have, the closer the result comes to the function of natural teeth.

review of a belgian patient who had All-on-6 in Budapest

That does not make All-on-6 automatically the better choice. Each case is judged individually on the basis of a CT scan and a consultation, and the dentist proposes the most suitable solution, taking your budget into account.

Key factAnswer
Who it suitsA toothless jaw, or a jaw with only a couple of teeth left
Implants per jawAll-on-4: four. All-on-6: six
Bone grafting or sinus liftAll-on-4: not required. All-on-6: not always required, but possible
Implant placementAll-on-4: around 90 minutes per jaw. All-on-6: around 2 to 3 hours per jaw
Visits to BudapestTwo; one more if bone grafting cannot be done in the same session as implant placement
GuaranteeLifetime on Alpha Bio and Nobel Biocare implants (the product); annual check-ups required

What do All-on-4 and All-on-6 have in common?

  • Both are permanent full arch solutions for the upper or the lower jaw.
  • Both carry a fixed bridge with a complete set of teeth. It does not slip or move.
  • Both stimulate the jawbone, which helps your facial appearance.
  • You can wear temporary teeth during the healing period.
  • The finished bridges look the same. The only difference is the two extra implants holding the All-on-6 bridge.

The full procedure is on the two main pages: All-on-4 in Hungary and All-on-6 dental implants in Budapest. This page focuses only on the choice between them.

All-on-4 vs All-on-6 head to head

QuestionAll-on-4All-on-6
Bone neededImplants go into the thickest part of the jawbone, so no bone grafting or sinus lift is requiredBone grafting is not always needed, but if it is, it can be done along with a sinus lift
StabilityGood, but less stable than six implantsHigher stability for chewing
Chewing loadShared by four implantsLess load on each implant, which supports a longer life for the implants
If one implant failsThree implants cannot hold the bridgeFive implants will very likely hold the bridge until an extra implant is placed
Healing timeShorter, as no bone augmentation is neededUsually 4 to 6 months; 6 months after bone augmentation
CleaningFewer posts to clean aroundTwo extra posts need more careful cleaning to prevent plaque and infection
Cost orderThe more competitive priceHigher; bone grafting or sinus lift adds to it

Who gets which: bone, budget and remaining teeth

The decision depends on your specific needs and the health of your jawbone. The dentist looks at your remaining teeth, your jawbone density and your budget. In practice it usually comes down to this:

All-on-4 zirconium bridge on the bottom teeth in Hungary
An All-on-4 zirconium bridge on the lower jaw. An All-on-6 bridge looks the same.

All-on-6 is usually the choice when

You need more extensive work with a fixed permanent bridge and your bone can take six implants. The teeth sit on more implants, so the support is better and chewing is well balanced. It suits patients who have lost most of their teeth in one or both jaws.

All-on-4 is usually the choice when

You have less bone volume and your budget is limited. The implants go into the thickest part of the jawbone, so no bone grafting or sinus lift is needed. Healing is shorter, so you have a fixed solution sooner.

Why bone changes the number of trips

If bone grafting or a sinus lift cannot be done in the same session as implant placement, you need one more visit to Budapest, and temporary teeth may not be attachable to the implants straight away.

  1. Let your X-ray show the bone for 4 or 6 implants. Upload it with the free quote form and tell us how many teeth need treating.
  2. Compare the All-on-4 and All-on-6 plans in writing. You hear back within a working day, with more than one treatment plan to choose from.
  3. Pick your option, then book the trip. Appointments are scheduled once you accept the plan.

What your 4-or-6 comparison quote includes

  • More than one treatment plan, for example on four and on six implants
  • A written quote with the number and length of visits, materials and guarantee conditions
  • No commitment: weigh four against six before booking a flight

Send my X-ray and compare 4 vs 6

Fixed, screwed or snap-on: how the bridge is held

Both solutions are fixed, but in different ways.

Before and after All-on-6 treatment
Before and after All-on-6 treatment.
  • All-on-4, screw-retained. You cannot take the bridge out, but your dentist can remove it with special tools, because it is attached to the implants with screws. This makes repairs, such as a chipped tooth, simple to solve.
  • All-on-6, bonded. The bridge is bonded to the implants and cannot be removed by you or your dentist. A chipped tooth can only be fixed by taking the whole bridge off.
  • All-on-6, screw-retained. Similar to All-on-4, with screws. It has a surcharge compared to the bonded version, but repairs to broken or chipped teeth are quick and cheap.
  • Snap-on All-on-4. Also four implants, but an implant bar is attached to them to support weak bone, and the denture clips onto the bar. You can remove it yourself, so it is easier to clean, and it is cheaper than the fixed bridge.

Both All-on-4 and All-on-6 bridges can be made with full zirconium or porcelain fused to metal teeth.

Worries about four or six implants, answered

Is full arch implant surgery safe?

A CT scan is always done before implantation. The plan made from your X-ray is confirmed or revised in Budapest, and the number of implants is not changed unless you agree.

Is the guarantee the same for 4 and 6 implants?

Yes: each Alpha Bio or Nobel Biocare implant has a lifetime guarantee on the product, whichever option you choose. It stays valid with annual check-ups, and guarantee work in Budapest costs you nothing.

What if my full arch bridge causes trouble at home?

If a problem comes up, you describe it and send photos if asked. The dentist decides on the treatment and length of stay. Your implant passport lists the size, type and position of each implant.

Final thoughts for decision making

Both are placed the same way and carry the same fixed bridge; the differences are price, healing time and the safety margin of two extra implants. The choice is made with your implant dentist, based on your remaining teeth, jawbone and budget. Either way, regular check-ups keep the result long-lasting.

    Excellent and very professional service from my first visit to the last. Extremely happy with the final result. I had the all on four system and i can now confidently eat and chew pretty much anything now with confidence and no pain. Had peanuts and pork cracking for the first time in 5 years Lol. Everything was arranged for me by my contacts Janos and Ben who replied to all my emails within the hour and was truly professional. My dentist Adam was excellent and put me at ease throughout the procedures. As and added bonus Budapest is a fantastic city to visit while your there

    Top dental clinic. Had all on 4 done. From first visit to the last all professional. Open policy, nothing hidden. From price quote to their work, all open minded. To all of you who were involved in my treatment and final result a big thank you. Update 22/6/25. Some time ago small piece front tooth broke off. Was scheduled for appointment on 16/6/25. Dokter Bodnar together with a lab technician had a look at it and concluded it could not be repaired. Immediately Doktor Bodnar told me a new bridge would be made for me without any cost for me as it was guarantee work. The new bridge was put in thursday june 19/6/25. This clinic absolutely trustworthy people. Highly appreciated and a big thank you.

    I had All-On-4 done on both jaws, 8 implants. This was during the pandemic but they managed everything very professionally. They did a great job, and came in under my quoted price. The Dentist convinced me I didn't need extra temporary dentures, and because of my bone structure he advised me to use the Ceramic on Metal dentures instead of Zirconia. My new teeth fitted perfectly the first time, they work great and look wonderful. You can trust they will be kind, skilled and professionals. It's been two months now, and yes, I highly recommend them.

    I had a brilliant experience from start to finish. All the staff were so friendly and helpful, and they all spoke excellent English. I was a little nervous about traveling abroad for my dental treatment, but I was soon put at ease. I am over the moon with the outcome, so much so that I have recommended Budapest Top Dental to my brother for similar treatments. The price I paid was extremely fair and much better than what I could find in the UK, but importantly, there was no drop in quality. The clinic is extremely clean and modern, with all the equipment you would expect in a dental clinic back home. I am happy to recommend Budapest Top Dental and would definitely use them again.

    I recently had the pleasure of undergoing dental treatments in Budapest, and it has been a truly outstanding experience from start to finish. Over the course of three visits, I witnessed a level of professionalism, expertise, and care that exceeded my expectations, leaving me with a radiant smile and a newfound appreciation for dental care in Hungary. From the initial consultation to the final follow-up, each visit was marked by a commitment to excellence that permeated every aspect of the dental experience. The dentists and staff were not only highly skilled but also demonstrated a genuine concern for my well-being and comfort. Beyond the technical aspects of the treatments, the warmth and friendliness of the entire team contributed to a positive and comfortable atmosphere. The staff's empathy and willingness to address any concerns or questions further underscored their dedication to patient satisfaction. In addition, the clinic itself was modern, clean, and well-equipped, creating an environment conducive to a positive dental experience. One of the standout features of this dental practice was the proficiency of the English-speaking dentists and staff. Communication is paramount in any medical procedure, and the fact that they were fluent in English made the entire process seamless. I felt understood, well-informed, and confident in the treatment plan presented to me. Overall, my experience with dental treatments in Budapest was nothing short of outstanding. The professionalism, proficiency, and friendliness of the dentists and staff made each visit a pleasure. If you are considering tourism dental treatments, I wholeheartedly recommend this clinic for a top-notch experience.

    I was really happy with everything. - I really love all about this clinic, the service was great, all the time I could have answers of my questions and regarding the appointments they were very flexible. - The transport from the airport was for free and on time and they were really nice even the driver helped me find out how I can take the key for the apartment that I rented. - The clinic was really really clean, which is very important for me and I think for all Swiss people. - The dentists are really nice and experienced. They explain all about the problem you have, you understand it and they also explain how they will treat you what is guaranteed and what not ……my dentist in Switzerland did not explain to me that what the problem with my tooth is, and it was not clear for me what will happen to me and my tooth during treatment moreover I was not informed of how much I must pay ... but in Budapest everything was the opposite, everything was clear to me before treatment. - Dentists in Budapest speak many languages and you will not have a problem if you do not speak English. There is also an interpreter in the clinic for free and she helps you communicate with the dentist. - Some of the price was really half from what we pay in Switzerland, like the root canal is 1000.- in Switzerland but in Budapest I only paid 440.- EUR. The dental implant is much cheaper in Budapest than in Switzerland and is of very good quality as it comes with lifetime guarantee what we do not have in Switzerland at all. - The quality of treatment was perfect. Thanks for all again!

    "Saved me thousands of £ and quality was first class! I had sticker shock when I found out how expensive 2 implants would be in the UK. I saw ads for Budapest dental work and by reading reviews built some trust. Once I spoke over Skype with Janos from Top Dental I felt confident that I was in good hands. My treatment over the next year was an excellent experience. The quote I was given was exactly what I paid. Airport transfers made the travel easier and the central location of the clinic made it easy to get to. I had two different dentists and both spoke English perfectly and obviously were well-trained, experienced and confident practitioners. I felt safe in their hands. I checked with my American dentist about the materials used by Top Dental and was told that Alpha Bio implants are considered the best by dentists. I'm only a month into my new teeth and loving them! Feels like natural teeth maybe even better. And if later I need more dental work (all root canals fail at some point) then the dentist said he can use these posts to hold more teeth or a bridge. Implants feels like a great solution to a very important part of my body. Thanks Top Dental for making this solution (at this low cost) possible!

    So delighted of my veneers result!

    I was planning to get veneers for a number of years and finally decided to get one this year. Of course, Turkey was one of the options but I chose Budapest as it’s closer to Ireland. I read great reviews for Budapest Top Dental so I did give it a go and asked for a quote. They offered me a promo package which includes accomodation and transportation (to and from) the airport so I grabbed it.

    My experience since I arrived in the airport was great. Taxi was on time to pick me up and bring me to the accomodation.

    Dr Farago Laszlo was superb. He was very professional and really knows what he was doing. My procedure went all perfectly fine, didnt have any issue and all I asked and wished for in terms of new smile were granted so I’m very pleased with the result!! So thank you Dr Laszlo!

    Last but not the least, Janus did a fantastic job in all the coordination of my trip. He’s very helpful and responsive all the time for any queries I may have. The accommodation and taxi company hired were all great.

    I definitely would recommend Budapest Top Dental if you want to have a superb smile, give them a go!!

Frequently asked questions

Which one is cheaper?

All-on-4. Six implants cost more than four, and bone grafting or a sinus lift adds to the price of All-on-6. The snap-on All-on-4 is cheaper than the fixed bridge version.

Can I get temporary teeth straight away?

Sometimes. Temporary teeth can be attached to the implants if they have enough initial stability. After bone replacement this is not possible. Still deciding between four and six implants? Read the FAQ page.
