What is All-on-4™ ?
Let’s dispense with the fancy words and terminology, it is now possible to insert a series of grade 4 or grade 5 titanium screws into the jawbone and have them bond with human bone. If this isn’t a miracle, I don’t know what is! Whatever terminology we assign to this treatment, be it “full mouth implants“, “full arch dental implants”, “All on 4”, or “All on 6”, the concept remains the same. A bridge of spectacular pearly whites is effectively anchored to these implants.
While the term “All-on-4™” was trademarked by Nobel Biocare, it’s essential to note that other reputable implant brands can equally champion this restorative concept. As a practitioner, my allegiance lies not with a particular brand, but with reliability and exceptional implant company support of the final result. Depending on patients’ individual needs, I select the appropriate design and brand of implants, providing them with a bigger range of implant brand options.
There are significant advantages to the newer techniques, which utilise 4-6 implants to replace all upper or lower teeth. Conventional full-arch dental implants often use 8 or more implants to replace a full arch of teeth, increasing the cost of treatment, and often requiring more invasive bone grafts and sinus lifts. The time spent on the treatment with conventional methods can be in the order of two years. Our expertise in All on Four and similar implant dentistry in Melbourne, Australia ensures lasting solutions for missing teeth, improving oral health and quality of life.
Modern techniques only require four implants, each arranged in a specific 45-degree manner so that the maxillary sinuses are often avoided, negating the need for sinus augmentation and bone regeneration to compensate for the lack of jawbone. Thus, reducing treatment time and cost.
All-on-4™ dental implants offer some distinct advantages over conventional implants:
- Only four implants are needed to support all upper or lower teeth
- Reduces the need for bone grafting to regenerate lost bone
- It’s a less invasive procedure
- Reduces healing and recovery time
- It’s a much quicker procedure
- Doesn’t require the same volume of bone if your teeth have been missing for a while
- You receive your new fixed teeth in as little as 24 hours after surgery
- Opens up the possibility of implants for previously unsuitable patients
- Great alternative for long-time denture wearers
BEFORE & AFTERS
MELBOURNE’S LEADING COSMETIC DENTAL CENTRE
Patient: Joanne
Condition: Joanne came in to see us for honest advice on what to do with her teeth. During COVID, a few of her teeth broke. She recalled that her teeth started deteriorating after her pregnancy, and she subsequently lost more teeth. She got by with dentures for some years but now was the time to so something as she is a business owner and couldn’t go around with lower teeth in such a condition. Joanne was on a mission to quit smoking, and with much needed support from her husband she embarked on the journey of full mouth dental implants.
Procedure: Six implants in the upper jaw and six in the lower jaw. Initially we made Joanne titanium reinforced acrylic teeth but following some further discussions, they were upgraded to zirconia bridges for strength, as Joanne grinds her teeth at night. She also wears a night guars (occlusal splint) to protect them.
Patient: Sotirios
Condition: Sotirios presented with multiple missing teeth in the upper jaw. He only had a few teeth remaining and wanted to replace them all with fixed implants, he knew his remaining teeth couldn’t be salvaged. A family friend had All-on-4 implant surgery a few years prior and mentioned how happy he was with the result. This was all the encouragement Sotirios needed, he was determined in proceeding with All-on-4 implants.
Procedure: Under General anaesthesia, Sotirios had his top teeth removed and replaced with 4 implants. They anchored well on the day so he was able to return the following day for his new but temporary upper bridge. The new teeth in 1 day made an enormous difference to his smile. Although he had to eat soft foods for five months until implants fully integrated, time passed very quickly, and Sotirios was now able to enjoy all sorts of food with his new upper titanium reinforced acrylic teeth. In the lower jaw, Sortirios decided to have his teeth whitened and have a partial removable denture.
Patient: Lan
Condition: Lan told us that she has been suffering from gum disease since she was 18. Her teeth were unstable and wobbly, and she noticed that they started to move forward in her mouth. She has lost a few teeth at a young age, and now wanted to improve their condition.
Procedure: After considering the option of maintaining some of the teeth and replacing others, versus replacing them all, Lan opted to replace all of the teeth with implants. Upper and lower immediate full arch All on 6 implants were done, which also required sinus lift grafting in the upper jaws. Even though Lan grinds her teeth at night, she decided to go for titanium reinforced acrylic teeth, and to wear a protective, grinding splint at night.
Google Reviews
What are Teeth in 3 days or Teeth in 1 day?
These are catchy terms that all mean the same thing. Basically, from the time your natural teeth are removed to the time when new temporary prosthetic teeth are attached to implants, is anywhere from one to three days. Depending on how quickly your dentist and technician can deliver them to you.
What are immediate full-mouth implants?
Besides a good marketing ploy, they’re the same as teeth in 1 day, the same as teeth in 3 days, or All-on-4™ dental implants, or any other term that’s commonly used to describe immediate full mouth dental implants. The difference is in the terminology and not the product.
Essentially, the difference between immediate and conventional implants is that immediate implants are inserted on the same day as teeth are removed. Whereas conventional restorative methods allow for considerable intervals between teeth removal, implant placement, and the final fixed teeth. Sometimes the difference can be up to a few years. That’s quite significant, and that’s why immediate full-mouth implants have gained popularity in recent years.
What Brand is Best for All-on-4™?
All on 4™ technique was initially pioneered by a Portuguese dentist by the name of Paulo Malo and the term All on 4™ was subsequently trademarked by a Swiss implant company called Nobel Biocare. Again, for complete transparency, I am not promoting any particular brand of implants here, my purpose is to shed some light on otherwise confusing language.
Nobel Biocare (All-on-4™) implants are great and there has been significant research published on the success of this concept. However, as mentioned earlier, any implant brand can be used, providing it satisfies the requirements of being a successful, well-researched implant that offers the flexibility and versatility of parts.
In Australia, the implant system has to be TGA (Therapeutic Goods Administration) approved and parts need to be freely available should the need for repairs or replacements arise. These days, there are many systems that meet these requirements. Such as Nobel Biocare, MIS, Biohorizon, Straumann, Neodent, TRI and many more. I tell my patients that Nobel Biocare was the original and is still a great choice but isn’t the only option anymore. So, if I were you, I wouldn’t get too bogged down with what system the surgeon uses, trust them to use the system he or she is comfortable with to achieve the best outcome for you.
What is All on 6?
The same as All-on-4™ but on six implants, simple. I could end it there but there is a bit more to it than that. Four implants are the absolute minimum to support a full arch implant restoration. However, if one implant fails, the whole structure comes crashing down like Humpty Dumpty off the brick wall. This is because three implants aren’t adequate to support a fixed implant bridge.
However, if you have six implants, and one or even two don’t integrate or perhaps they develop a problem down the track, your teeth restoration can still be adapted without too much trouble. More implants mean more support and more security for the long-term prognosis of your implants.
Are you suitable for All-on-4™?
If you’re a living, breathing person, who has lost all or most of your teeth to decay (caries) grinding (nocturnal bruxism), or your teeth are waving in the breeze due to periodontitis (gum disease), and you are fed up with failing, damaged, and missing teeth, you’re probably a candidate. Provided you are committed to turning over a new leaf and caring for your new implants daily at home.
- You are fed up with your dentures which rub your gums, cause discomfort, and move when you eat or speak
- Your teeth are failing due to significant wear, decay, or periodontitis, causing you significant pain and discomfort, affecting your confidence, how you look and your ability to eat
- You’ve been unable to replace your teeth due to conventional implant methods, insufficient bone or high-cost
Why are some people not suitable even for All-on-4™?
Even if you are sick of your teeth, and are ready to replace them, there are very important questions that need to be asked before considering this treatment:
Can your teeth be saved? If your dentist recommends a quicker, cheaper, and more effective treatment option for you, it’s in your best interest to listen. There is nothing better than your natural teeth. We understand that you might’ve lost all faith in them and they’ve given you trouble over the years, but if there is a good chance that we can save them, take that chance. We are happy to educate you and show you how to look after them and maintain them at home. Keeping your natural teeth is always a better option than replacing them.
Do you smoke? Smoking reduces blood oxygen supply and impairs healing, hence why people who smoke have lower success rates. Both in the initial phase of healing, as well as over the long term. We encourage our patients to quit smoking permanently. This increases your chances of a good outcome. Understandably this is easier said than done. However, we can discuss strategies to assist you and prescribe medications you can take to help you quit. If you’re not ready to quit, doesn’t necessarily mean that you can’t have implants, it just pays to be aware of reduced surgical and long-term success rates.
Is your diabetes uncontrolled? Uncontrolled diabetes can also impede healing and result in a higher risk of implant failure. Diabetes potentially renders people more susceptible to infections and vascular diseases. It’s not all doom and gloom, if you work with your medical practitioner to get your diabetes under control first, you would be perfectly suitable to have dental implants.
Do you have high blood pressure? Hypertension is one of the most common conditions in Western countries. With the help of healthy whole food plant-based nutrition, antihypertensive medications, and adrenaline-free local anaesthetics, blood pressure can be stabilised, ensuring that it’s safe for you to undergo implant surgery.
Are you under the age of 25? Some rare genetic conditions can result in young adults missing their natural teeth. You would need to wait until you’re over 25 to have all your teeth replaced with implants.
Do you have a systemic disease? Certain systemic conditions such as Leukaemia, radiotherapy, and chemotherapy can impede healing, so it’s not advisable to have oral surgery until you’ve recovered.
What if you have osteoporosis? This is one of the common questions that patients ask. Interestingly, jawbone isn’t as likely to succumb to osteoporosis as weight-bearing bone, so most people with osteoporosis can still undergo implant surgery. There is one caveat – you must not be taking medications that inhibit bone turnover. If you do, it is important to consult with your medical doctor to assess your suitability for implant surgery.
Are you taking medications for osteoporosis? Some medications such as bisphosphonates slow down bone healing and would require careful consideration before committing to implants.
Do you have periodontal disease? Advanced gum disease is one of the most common reasons people lose their teeth and require full mouth implants. Patients often get concerned that their new implants will also be affected by this condition. This is both true and false. In assessing your risk it’s important to understand that periodontal disease is not only treatable in the first place but it’s also preventable. Few people can believe this fact when they are facing the prospect of having to lose all their teeth. Nevertheless, this is true, and if your dentist treats it in time, coupled with meticulous home care, periodontitis can usually be treated.
Implants can develop a similar condition called peri-implantitis. Whereby bony support is similarly lost around your implants to what would happen to a natural tooth with gum disease (periodontitis). It’s still not well understood and thus has limited treatment options, although this area of science is evolving. Both the skill of the surgeon as well as meticulous home care of your implants can minimise the risk of this condition. In other words, with appropriate care, you would be a great candidate for implants.
Have you been told you don’t have enough bone even for All on 4? For some candidates who don’t have adequate bone and require sinus lifts and bone grafting to even place implants, full arch immediate implants aren’t the best approach. A delayed or staged approach is more appropriate, which means that you get the same result but over a longer period. Teeth are removed first, followed by bone grafting, which is followed by the placement of implants. With at least a few months between each stage, you can appreciate that this process would take longer than if bone grafting was not required. This is not a contraindication as such, just a variation to the immediate approach. If a dentist determines that there is not enough bone in your mouth to anchor implants. Bone grafting could be considered before implants are placed.
What is the process?
Ok, so to sum it up, here are the steps at our practice:
1
Consultation
We begin with an initial consultation to discuss your concerns and identify the time frame and treatment options. This is an extended consultation so you will have an opportunity to ask plenty of questions. Dr Helen will begin her investigative process by examining your mouth and assessing your current situation, overall health, and suitability for full mouth implants.
2
SUITABILITY SCAN
Proceed with a scan (Cone Beam CT) to assess the volume and density of your jawbone and suitability for full mouth implants
3
PLANNING
Arrange a series of appointments where we take photographs, 3-D scans and impressions of your mouth as well as the preparation of your immediate teeth
4
SURGERY
A qualified anaesthetist will administer general anaesthesia. You will have a relaxing day asleep while we work away removing your remaining teeth, inserting new implants, and taking measurements for your new teeth. The amazing thing about immediate implants is that this will all be done in one day while you are asleep.
5
NEW TEETH
Voila! You will go home overnight and return the following day for your new but temporary teeth. This is exciting! Very exciting for all of us. We attach an acrylic bridge to your new implants and now you can go home smiling.
6
Recovery
The mouth heals surprisingly quickly and provided you follow our instructions and take your medications, it usually happens uneventfully. We will give you clear instructions on what to do and not to do after your surgery as well as how to care for your new implants. It will take five to six months for your jawbone to grow around your implants, so particular care should be taken to eat soft foods and not apply undue pressure on them.
7
Suture (stitches) removal
You return in two weeks to have your sutures removed.
You will need to see us on a monthly bases for quick reviews to make sure the healing process is proceeding well
8
New bridge
In about five months, provided your implants have integrated with the jawbone, it’s time to make you a new, final bridge. Again, we’ll see you several times to take measurements and try your new teeth in to make sure they fit and suit your face and you are happy with them.
9
Maintenance and care
Please care for your implants and your new teeth like you would for your most precious possession and visit your friends at the dental office once every six months for check ups and cleans.

Is it painful?
Surprisingly, pain is a rare complaint we get. Patients don’t usually call us at night in pain wondering how to fall asleep. So, what’s our secret? Medications! We are so spoilt with modern medicine. A combination of non-steroidal anti-inflammatories, short-term corticosteroids, and antibiotics work a treat. These medications keep people comfortable and sleeping well at night. They’re not so good that you would want to come back for more… but almost.
The most common demographic of people we see who require full mouth implants are people who have a dental phobia. They are often terrified to even sit in the dental chair at the beginning, but by the end of the process, they jokingly tell me that they’ve been cured of their fear. Really? Does surgery cure fear? Well, that’s what my patients tell me.
Can anything go wrong?
Risks and complications
All-on-4™ implant surgery has a very high success rate. However, any surgical procedure carries risks and complications. Both the skill of the surgeon as well as meticulous home care (of your implants) can minimise the risk of this condition.
Minor and common postoperative complications include:
- Swelling, bleeding, slight pain, and bruising of the face – with the help of medications, people are often surprised by the minimal amount of discomfort they experience after surgery.
- Infection –would be very common if it wasn’t for the antibiotics we prescribe. They minimise the chance of any post-operative infections. However, with the emergence of superbugs, this complication remains a possibility and needs to be managed by your surgeon. You will also be advised to rinse your mouth with chlorhexidine mouth rinse for two weeks after surgery.
- In the upper jaw, unless you are having zygomatic implants, there aren’t any nerves in the vicinity so there is no risk of nerve damage). However, the sinuses, which are air-filled cavities in your face, are nearby. An implant can sometimes penetrate this sinus space. This often doesn’t cause any long-term complications but on a rare occasion can cause sinus infections, in which case a follow-up procedure might be required to alleviate this situation, or you might even be referred to an ENT specialist.
- Other less serious complications of the prosthesis, which are more like maintenance issues rather than complications can include fractures of the teeth and components, which are usually repaired or replaced.
More serious complications:
- Implants not integrating – upsetting to all of us, but it’s not the end of the world – your surgeon will have to decide whether to remove the implant and start again or if it can be saved. This complication can prolong the length of the treatment as well as possibly increase the cost.
- In the lower jaw, there is a nerve, namely the “Inferior Alveolar Nerve”, that’s responsible for supplying sensation to the lower lip, the chin, and the teeth. There is one on each side of the jaw. Occasionally through grafting or implant placement, this nerve is temporarily or permanently affected, resulting in altered sensation in the lip and chin on the corresponding side of the face. Often this sensation can resolve as the nerve heals but sometimes this sensation could persist.
- Delayed problems with implants can arise too, especially if you are a smoker or have uncontrolled diabetes or you’re on bisphosphonate drugs.
How should you choose a surgeon for full-mouth implants?
It’s really important to pick a skilled, experienced dentist but it’s also important that he or she is kind, compassionate, and cares about the outcome, because what better joy is there for a surgeon than to see new life injected into their patient? You want your surgeon to hold their breath when they are doing it. No matter how experienced, they need to be transparent, honest and be invested wholeheartedly. A recommendation from a friend is worth gold but if you don’t know anyone who’s had this done, perhaps meet a few surgeons to see how comfortable you feel with them. Your gut feeling will tell you who to go with.
Surgery is not a walk in the park. When you undergo surgery, please remember this. Hopefully, you will be one of 9 in 10 for whom it all goes well rather than 1 in 10 whose implants develop complications. It’s not all up to the surgeon but many factors are.
Cost of Full mouth/All-on-4™ implants
The average price of full arch implants in Australia is $23,000 – $30,000 per arch.
You only get two chances in life when it comes to your teeth. The first set is the one that you were born with, which came for free, and the second set will be your last chance and it will cost you. A lot. Most likely you will not get a third chance. So full dentures might be the only option left. Implants are not easily replaceable, as they leave such a deficit when removed. So, it’s crucial to understand that your best chance is getting them done right the first time.
While all licensed dentists appear to have all the necessary qualifications, there are several factors to consider:
- Dentist’s level of education and experience in executing the procedure to a high degree of accuracy and precision, as well as in managing any complications that may arise.
- Durability of the materials used. High-quality craftsmanship and materials will ensure longevity and save you frustration and money in the long run. You know yourself “You get what you pay for”, and it’s no different with implants. Remember, most people will only get one chance when it comes to implants.
- Every person who is involved in the design, construction, and installation of your new teeth needs to be an expert. Experts constantly keep abreast of new research and technology. They have done the procedure many times and they know what’s involved and how much it costs to provide the service at a standard that keeps you happy and also offers you post-operative care in case of complications. After all, their reputation is at stake. Thus, they want to be fairly remunerated for their effort and will provide the service at a fee that reflects real costs.
How can you afford All-on-4™ implants?
- Pay in increments over the 6-month duration of the treatment
- You can take out a payment plan that’s specifically designed for medical treatments. This is good if you need implants now but happy to pay them off for 24 months. Whilst this option allows you to have the treatment that you need now, it will come with interest. I advise my patients to explore all options. Perhaps a bank can offer a better deal.
- You might be able to access a proportion of your superannuation on compassionate grounds. You would need to make an application with the ATO, and if you suffer from acute or chronic pain your GP or your dentist can help you through this process. You can learn more about this by heading to the ATO website https://bit.ly/3ahM5O3
