All On 4 Dental Implants

Fewer implants & faster recovery times

What is All-on-4?

All-on-4 is not an invention, but rather a treatment technique that has continued to evolve over time. The term All-on-4 refers to “all” teeth being supported “on four” dental implants, a surgical and technique prosthodontics procedure for the total rehabilitation of a patient’s badly broken-down teeth, decayed teeth or compromised teeth due to gum disease. The four implants support a fixed full arch prosthesis with 10 to 14 teeth

The concept itself, allowed the total rehabilitation of a full set of teeth supported by as few as four fixtures. This allowed Prosthodontists to avoid bone-deficient areas by placing implants on angles into ‘healthy bone’ dense area where the implant fixture could successful osseo-integrate (bond) into the jawbone.

Two dental implants are placed at the front, with two at the back, placed at a slight angle, providing enough structural support to hold a full, fixed set of new prosthetic teeth. As there are less implant fixtures placed, it provides a faster and less invasive option. The natural-looking teeth are fixed in your jawbone enabling you to not only look good, feel good but also function very similar to your natural teeth.

The cost of the All-on-4, Full Arch Fixed Implant at Aria Dental in Perth, Western Australia starts from $17,500.

With the advances in technology and in science, at Aria Dental, our specialist Prosthodontist can now offer stronger and more securely placed patient options using specialised diagnosis equipment and techniques like bone grafting, to deliver All-on-5 or All-on-6 prosthodontic procedures for more superior results.

Suitable All-on-Four implant candidates

There are no physical contraindications that would stop a patient from having the All on Four completed. If patients have significantly reduced bone availability in the upper jaw, they may be prescribed zygomatic implants rather than conventional implants.

Most people are suitable for the All-on-4 implants procedure, especially if you:

  • No longer have any of your natural teeth
  • Find wearing dentures uncomfortable
  • Have advanced gum disease or many decayed, damaged teeth
  • Have problems eating a wide range of foods with your dentures
  • Lack adequate bone tissue for conventional dental implant procedures

Due to the benefits in look and feel, All on Four has become a popular alternative to dentures for replacing a full set of teeth.

One of the many benefits of the All-on-4 is that it enables you to get a new set of teeth in just one to three days. You could have your teeth extracted, then have implants placed on the same day. Also on that day, your surgeon could place a temporary bridge so that no one will know that you’ve had your teeth removed – or implants placed.

After you’ve completely healed from your implant surgery, your dentist will then fit you with a permanent fixed bridge.

All-on-4 benefits:

  • A long-term solution
  • Higher success rates than traditional implant techniques (Around 98%)
  • Takes only three days (or one day with Same Day Teeth technology) Traditional dental implant procedures would require multiple visits and could take up to a year to complete.
  • The entire procedure is quick, taking only a couple of hours
  • A more economical option than some alternative techniques for full mouth rehabilitation that require bone grafting and more than four implants.
  • Virtually eliminates the need for bone grafting. Consequently, the procedure is suitable for patients that are otherwise not eligible for dental implants, such as those with osteoporosis, diabetes or health conditions contraindicated for bone grafting.
  • Helps prevent bone resorption
  • Enjoy a greater quality of life, improving nutrition & well-being
  • Lifelike, natural-looking teeth that look and feel like your own.
  • Easy to maintain – good dental hygiene is not complicated


A comprehensive oral health evaluation where we’ll carefully assess your suitability for the procedure and discuss any concerns you may have.


To plan the best treatment for you, we need diagnostic records. We’ll take multiple impressions (moulds) of your teeth, x-rays, CT scans & clinical photos.


Implant placement in a surgical procedure that may take several hours. After, we’ll take impressions of the implant positions, then place small healing caps over your implants until a prosthetic device can be inserted.


Your teeth are “tried in” your mouth using only wax to assess the position and aesthetics of your teeth. Changes can be made to maximise the aesthetics.


24 hrs after your implant procedure, a provisional implant prosthesis may be inserted. Fixed firmly in place, it will have space underneath to clean around the implants & gums. Healing takes approximately 3 months.


After the recommended time, your definitive implant prosthesis will be placed. This will be a quality prosthesis including extremely lifelike ceramics and acrylics.

Frequently Asked Questions

How much does the All-on-Four procedure cost?

Approximately speaking, the price of the All-on-4 procedure starts from $17,500. For an accurate quote, please book in for a free consultation with our dental specialist.

What is the success rate of the All-on-4 procedure?

The success rate for the All-on-4 is high, with several published studies reporting success rates between 95% to 99% for up to 10 years.

Will I be awake during my implant procedure?

Preferably, you will be heavily sedated during the All on Four procedure. The options available for sedation include general anaesthesia, IV sedation or oral anti-anxiety medication. Regardless of which sedation option you choose, your comfort throughout the procedure will not be compromised. The majority of patients and dental clinicians consider IV sedation most appropriate for the prescription of All on Four.

Will I look swollen after my implant procedure?

For the first couple of days after your procedure, you may experience some minor swelling or bleeding, which is normal and unlikely to cause any pain

Will I be uncomfortable or in pain after the All-on-4 procedure?

It is natural to experience swelling and discomfort after the All on Four procedure. For the majority of patients, the discomfort subsides in the first forty-eight hours. Patients who are prescribed analgesics such as Panadeine Forte and anti-inflammatory medication can be well managed and comfortable during the initial healing phase. If a patient experiences undue significant pain, they are advised to contact the clinic immediately for the prescription of alternative medications.

Is there such a thing as All-on-6?

All on Four is defined as the delivery of an implant-fixed prosthesis within twenty-four hours supported by four implants. In many circumstances additional implants may be required to provide the fixed prosthesis with additional support. This may be the case for patients who have reduced bone quality and quantity or who wish to replace the very posterior teeth in their mouth. The placement of one or two additional implants, which can be termed All on Five or All on Six, is sometimes required.

Patients who present with risk factors such as periodontal disease or smoking, which are known to increase the risk of implant failure, may be recommended to have additional implants placed. In the event that an implant becomes problematic, the existing fixed prosthesis can still remain in function despite any complications that may occur in the future.

How long do All-on-Four implants last?

As with any dental implants, once your implants have been fused to the bone, they should last for decades, if cared for properly. Many dental implants have been kept perfectly in place for more than 40 years.

How long does it take to have the All-on-4 procedure?

The All-on-4 procedure usually takes between 1-3 days, depending on the techniques used for your surgery.

Why is it that you don’t require a bone graft for the All-on-4?

The All-on-4 procedure is a little different from other dental implant procedures as two implants at the back of the jaw are angled to sit in places where there is more bone volume to support the bridge. Consequently, the need for a bone graft is eliminated.

Any surgical or invasive procedure carries risks. Before proceeding, you should seek a second opinion from an appropriately qualified health practitioner.

What is osseointegration?

Osseointegration is where a direct structural and functional connection between living bone and the surface of a load-carrying implant is made. After a dental implant is placed into the jawbone, over time, the bone grows right up to the implant surface, stabilising the implant without any other soft tissues or fibres between the bone and implant.

What is bone resorption?

When you lose some or all of your teeth, you also lose your tooth root, which is vital for stimulating your jawbone. Stimulation keeps your bones strong;  without this, the bone starts to resorb or disintegrate. Eventually, the resorption can be quite noticeable, with the individual’s lower face and mouth starting to fall in. Dental implants help prevent bone resorption as the implant acts as an artificial tooth root, stimulating the bone and maintaining a more youthful appearance.

Any surgical or invasive procedure carries risks. Before proceeding, you should seek a second opinion from an appropriately qualified health practitioner.
