What Do You Know About All-On-4 Dental Implants

A Brief History of All-On-4 Dental Implants

Read about brilliant people whose discoveries and inventions made it easy for people who have gone through tooth loss but are looking for a permanent solution to replace their missing teeth.

Who Should You Thank For the invention of Dental Implants and All-On-4 Dental Implants?

The mid-1950s

Meet Professor Per-Ingvar Branemark, a Swedish orthopedic surgeon who could prove the possibility of osseointegration.

Professor Branemark had placed a titanium rod in a rabbit’s leg and intended to see how the rabbit’s bone would heal. He was researching how blood flow could affect bone healing.

Professor Branemark and his team noticed that the titanium rod had fused with the bones in the rabbit’s leg.

Per-Ingvar Brånemark could prove that bone can fuse itself with non-organic elements like titanium. The discovery paved the way for the development of dental implants and an innovative method to replace teeth, all-on-4 dental implants.

Was The First Human Case Successful?


Gosta Larsson of Gothenburg was the first human subject who volunteered to have dental implants fitted in his mouth to replace his missing teeth. Gosta Larson was not a single tooth replacement case but a full arch rehabilitation on several fixtures.

The treatment began with professor Branemark placing titanium rods in Larson’s mouth. After a few months and the completion of the healing process, a full set of prosthetic teeth was inserted into the patient’s mouth. Larson’s case was successful; he enjoyed his new smile for over 40 years.

FDA Approval


Professor Branemark founded the company Nobelpharma in 1981. (later renamed Nobel Biocare)


Using titanium dental implants was approved by the FDA in 1982.

Who Invented All-On-4 Dental Implants?

A Breakthrough in the Implant Dentistry: The advent of AO4 Dental Implants


A Portuguese dentist called Dr Paulo Malo (sponsored by Nobel Biocare) came up with a new idea about replacing missing teeth with dental implants.

His research and studies around the efficacy of this innovative approach were supported financially by Nobel Biocare.

He proved that an entire arch of prosthetic teeth could be supported by inserting just four implants in the jawbone.

A Full Arch Rehabilitation With 4 Dental Implants

During oral surgery, two dental implants will be placed in the front of the patient’s arch and two angulated dental implants in the back of their arch.

Dentists could avoid sinus cavities in the jawline by applying all-on-4 dental implants.

Tilting the two dental implants at 45 degrees angle allows areas in the jaw bone with low bone density to be avoided.

Note: Patients with insufficient bone density can not be treated with traditional dental implant treatment. Such cases need to first go through a surgical procedure called bone grafting.

Bone grafting encourages bone growth and is necessary if the patient does not have enough bone to support dental implants, typically due to bone loss.

Rebuild Your Lost Confidence with All-On-4 Dental Implants

Who Is All-On-4 Dental Implants For?

“All-on-four dental implants” is considered one of the best treatment options to replace natural teeth affected by some oral health conditions, like gum disease, severe tooth decay, or trauma.

The treatment is suitable for patients who:

  • would like to improve their dental health and self-esteem
  • have lost some or all their permanent teeth
  • would like a permanent solution to replace their worn-down front teeth
  • suffer from teeth severely impacted by periodontal disease
  • are tired of removable dentures
  • are looking for a more affordable replacement teeth option
  • would like to have an entire set of prosthetic teeth within a few days following their surgery
  • are looking for the closest best thing to their natural teeth

Certain patients who have gone through bone loss and are not good candidates for traditional implants can benefit from other treatment options like all-on-4 dental implants.

Why Is All-On-4 Dental Implant Procedure Preferable to Removable Dentures?

“AO4 dental implant” is not a removable option and will provide patients with a fixed bridge that looks and functions like real teeth.

Dentures are not fixed; they may fall or slip and cause a lot of discomfort for patients.

Practising oral hygiene is easy with all-on-four dental implants. You can brush your new teeth like your natural teeth. Dentures are removable and need to be taken out to be cleaned.

While all-on-four dental implants preserve bone quality, dentures may gradually cause bone loss and deterioration.

How Many Teeth Are in All-On-4?

Patients will receive a fixed bridge containing 10 to 14 teeth supported and anchored by four implants.

How Strong Are All-On-4 Dental Implants?

Four implants will be surgically inserted into your upper or lower jaw to support a full arch of teeth. Therefore, they won’t move, slip, or fall and, with proper care, can be a lifelong investment in a beautiful smile.

Several factors may affect the health of your dental implants, including:

  • poor dental health (dental plaque buildup)
  • Bruxism
  • smoking
  • poor implant quality

Here’s another article to give you more ideas on your AO4 decision:

Who Performs the Surgery?

An oral surgeon or maxillofacial surgeon in Brisbane will carry out the all-on-4 dental implant treatment.

Can I Get All-On-Four After Gum Disease?

Gum disease or periodontal disease refers to the infection and inflammation of the gums that may damage the soft tissue and the bones that support the teeth. Gum Disease

The most common reason for dental problems is poor oral hygiene and plaque accumulation at and below the gum line.

In severe cases, and if the condition is left untreated, patients may experience bone loss.

Patients can receive all-on-4 dental implant treatment in Brisbane if the affected areas are treated, or the underlying jaw bone has been left intact.

Zygomatic implants are another option that a dentist may suggest if patients with periodontal disease have little bone to support conventional implants.

The Treatment Process

Initial Consultation

The dentist will review your tooth replacement options to see which is best for your missing teeth. Your dentist will assess your oral health and utilise screening tools to evaluate your jaw bone quality and density, teeth, and gums.

Personalised Treatment Plan

If the cosmetic dentist decides that the treatment suits your situation, they start creating a precise treatment plan for you. The treatment process, risks and possible complications, costs, the recovery process, and pre-surgery procedures will be explained during your consultation session.

Pre Surgery Procedures

The cosmetic dentist will use advanced techniques to determine the proper location for the implants. Your dentist may decide to extract any remaining teeth for better results.


The surgery may be performed under general anaesthetic or IV sedation.

Placement of The Titanium Implants

Four small titanium screws will be surgically inserted into your jaw at a proper angle. Patients will typically receive a temporary set of teeth after dental surgery.

After passing the healing period, you will receive your final teeth.

Which One Is Better, All-On-4 or All-On-6 Dental Implants?

All-On-4 or All-On-6 Dental Implants

Both procedures will serve the purpose of replacing missing teeth and are performed to improve a person’s oral health and smile. They are both surgical treatments.

The most apparent difference between the two is the number of implants surgically inserted into the patient’s jawbone.

According to some dental experts, all-on-6 dental implants provide additional stability. They believe when the pressure of biting and chewing is distributed more evenly, the longevity of the prosthetic teeth will extend.

Can I Use An Electric Toothbrush For My AO4 Dental Implant?

One of the many benefits of AO4 implants is that they do not require any particular maintenance beyond being brushed twice a day.

Your cosmetic dentist in Brisbane can give you better and more specific guidance on how to maintain dental hygiene after receiving your implants.

Generally, using an electric toothbrush to clean your new permanent dentures is safe after the recovery period is completed.
