The All on 4 Procedure Details Pros and Cons

Everyone deserves a smile they can be proud of. If you’re suffering from dental disease or missing teeth, you may be wondering what your treatment options look like. Fortunately, dentistry has come a long way in the past 25 years. Gone are the days when dentures were the only solution to missing teeth. All On 4 dental implant technology has revolutionised modern dentistry and empowered patients all over the world. So, what does the All On 4 procedure entail? We unpack everything you need to know about the industry-changing treatment here.

Getting Your Teeth Fixed

Getting your teeth fixed is essential for more reasons than one.

Missing teeth, gum disease, and bone loss can have serious impacts on your physical and mental health. These dental issues can result in changes to your bite — and therefore your diet — and leave your body vulnerable to infection. Understandably, missing teeth, in particular, can also lead to confidence and self-esteem issues.

You deserve a healthy smile you can feel good about. All On 4 dental implants are the ultimate solution to major dental concerns. They provide patients with permanent, realistic replacement teeth. Not only do they deliver an amazing smile, but they also help to restore facial height, correct your bite and jaw positioning, and improve your speech.

So, what are All On 4 dental implants? Let’s take a closer look.

What is All On 4?

All On 4 is a dental implant procedure where four implants are inserted into the gum lining (two on the upper arch and two on the lower arch) to support a set of permanent replacement teeth.

All On 4 is most commonly recommended for patients who are missing multiple teeth, or who have experienced bone decay or gum disease. They are designed to replace an entire set of missing teeth.

While traditional dental implants can also replace a full set of missing teeth, the differentiating feature of the All On 4 procedure is the positioning of the posterior implants.

The back implants are expertly tilted at a 45-degree angle and inserted into the anterior maxilla, which is the part of the jaw with the highest bone density. This unique positioning allows the implants to effectively support the tooth replacements, even in patients who may have experienced bone loss.

On the contrary, the traditional implant treatment requires a strong jaw bone, which means patients often need to undergo bone grafting surgery. These limitations mean traditional implant treatment can take as long as three months.

The All On 4 procedure can be completed from start to finish in just three days. 

It’s for this reason, and a number of others we’ll look at below, that All On 4 implants are widely considered the preferred tooth-replacement treatment.

All On 4 Dental Procedure

It can be reassuring to know what to expect from your All On 4 procedure prior to treatment.

The three-day treatment will involve an initial consultation and design session, a preparation session, and the final All On 4 implantation visit.


Step 1: Initial Consultation and Design Session

At your initial consultation, your dentist will get to know a bit about you, your dental history, and your goals for your new smile.

This is an opportunity to chat about what a perfect smile looks like to you, and to address any concerns you may have.

If your dentist determines that All On 4 is the right solution for you, they will begin designing your bespoke All On 4 treatment plan.

During this initial consultation, your dentist will also take a 3D bone scan that will be used to construct your new smile.


Step 2: The Foundations and Your Trial Smile

The next stage is preparing your gums and bone for your brand new smile. Your dentist will need to do some foundational work to ensure the success of your dental implants.

Your dentist will work to remove any infection or disease so that your gums are healthy and ready for treatment. They will then insert the four implants. This will be done under local or general anesthetic to keep you comfortable and pain-free. This step will take place on day one of your three-day treatment.

On day two, your dentist will work with you to design your new smile. When it comes to the design of your smile, you’re in the driver’s seat. Your dentist will ensure they have a thorough understanding of your smile goals and will begin bringing your vision to life.

Together, you will consider the shape, colour and size of the implants. Your dentist will also give you a wax trial smile, which is essentially a preview of what your new smile will look and feel like.

From here, you can work with your dentist on adjustments and changes to ensure you’re 100% happy with the result.


Step 3: Final Placement

On the third and final day of treatment, the final All On 4 tooth replacements will be inserted.

Your dentist will do a check and review your smile. This review allows you to make any final changes.

Your dentist will continue working on your smile until you’re completely satisfied with how it looks and feels. After all, you’ll have this smile for the rest of your life.

All On 4 Pros and Cons

Prior to any procedure, it’s important to understand the pros and cons. What are the benefits, and what are the potential drawbacks?

We unpack both below.


The benefits of All On 4 dental implants can’t be overstated — it is one of the most effective cosmetic dental treatments on the market.

  • You can take the lead in designing your smile.
  • The treatment is effective even if you have experienced bone loss.
  • The treatment is very quick and delivers life-long results — the procedure takes just three days, compared to three months for traditional implants and 2 – 4 weeks for dentures.
  • They are permanent, meaning you won’t need to worry about replacements down the line.
  • All On 4 implants function exactly like real teeth do, unlike dentures which are removable and require adjustments over time.
  • They deliver the most natural and realistic look and feel.
  • You can bite, chew, floss, and brush your teeth as you would with real teeth.
  • They allow you to maintain proper oral hygiene and a well-balanced diet, both of which may have been difficult with missing or decayed teeth.


All On 4 implants have an extremely high success rate.

The cons usually associated with tooth replacements — speech impairment, having to remove the implants, implants that break or get lost easily — do not apply to All On 4 implants.

Issues can arise when implants are incorrectly positioned by poorly trained dentists. Positioning the implants too far forward can cause the gums to recede while placing them too far back can cause the teeth to look too bulky. If they’re positioned close to the biting surface, the teeth may look unnaturally short.

Visiting a highly-skilled dentist, like the team of dentists at Dental Boutique, eliminates the possibility of these issues occurring.
