What is an All on 4 ?

If you are missing teeth (or are soon to lose all your teeth) because they have broken down, you have several options for your full teeth replacement. One of the most common techniques is to use an All on 4 dental implant techique to support a set of new, manufactured teeth. If you have lost all your upper or lower teeth, a full arch fixed implant prosthesis, may be a good option to restore your smile’s health, function, and aesthetics, instead of a traditional denture.

All on 4 is a treatment technique, where ‘all on 4’ refers to “all” teeth being supported by 4 titanium dental implants. This is a procedure for the replacement of a patient’s badly broken-down or terminal teeth, decayed teeth or compromised natural teeth. The four implants support a new set of teeth, on a fixed full-arch prosthesis displaying around 10 to 14 teeth.

The All on 4 implants concept itself, allowed the total rehabilitation of a full set of teeth (a full teeth replacement), supported by as few as four fixtures. This allowed clinicians to avoid bone-deficient areas by placing implants into healthy bone dense areas ,where the implant fixture could successfully osseointegrate into the jawbone.

Two 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 fewer implant fixtures placed, it provides a faster and less invasive option. The new natural-looking teeth are fixed to your jawbone enabling you to not only look and feel good but also function very similar to natural teeth.

All on 4 are for less complex cases and are typically made using an Acrylic-made arch. If you have a more complex oral requirements and require restorative dentistry, Learn more about Full Arch Rehabilitation here.

Restoring Smiles – Before and After – All on 4 Treatment

Before and After of four patients

All-On-4 Procedure


Your first appointment involves a comprehensive evaluation of your oral health, any gum disease and teeth replacement needs. A comprehensive oral health evaluation by our Principal Prosthodontist is completed, where he’ll assess your missing teeth and suitability for an All on 4 Perth procedure. He carefully assesses what would be the best solution that addresses your concerns and personal requests. He will discuss any concerns you may have and aim to provide you with advice and recommendations that suits your needs, both clinically and financially. NB: If you have gum disease or other treatable issues, you may have these dealt with before proceeding with your implant treatment.


Following acceptance of the proposed treatment plan to assist in your rehabilitation, we will attain the required diagnostic records and clinical photographs. This involves digital impressions of your missing teeth to construct a study model, take clinical photographs, and a three-dimensional radiograph (x-ray).  These records are essential for the planning phase, where to place your four dental implants and to determine the most appropriate path to reach the desired outcome for you.


This appointment is often completed when you are sedated. The number of implant fixtures required will depend on various factors, that are determined during the treatment planning phase. These include your bone quality & quantity and the design & type of prosthesis that is most suitable for you. The surgical procedure of placing the tiny dental implant fixtures into you jaw may take a few hours to complete. Once placed, the implant fixtures will be covered by small healing caps until your final prosthesis is ready to be inserted.

Once the dental implant fixtures are placed, a precise digital impression is taken of the implant positions. This is sent to our in house dental laboratory so a temporary (or provisional) prosthesis can be fabricated. Our in house laboratory, is a cost effective solution which allows our products to be more affordbable, with patients receiving a much high quality product at a much lower price than elewhere.


The provisional prosthesis will be scheduled to be inserted soon after the implants fixtures have been placed. Your provisional prosthesis is generally made of acrylic and metal. It is screwed onto the implant fixtures, and so you will not be able to remove it. It will have a space underneath to allow you to clean around your new implant fixtures and gums. There will be less “teeth” on the provisional prosthesis, and you will wear this prosthesis for a minimum of three months. In some case, an additional replacement provisional teeth is required as the gums heal.

The provisional prosthesis helps your dental professional confirm the correct shape of the teeth and allow changes to be made should you have trouble adapting to the shapes and new contours of the design. Patients often take several weeks to be comfortable with them. During this provisional / healing period, speech changes or eating ability may be slightly compromised.


It is common that you may develop varying grades of bruising or swelling and require anti-inflammatory and pain relief medication. The swelling will generally reach a maximum two days after the surgical procedure. Written post-operative instructions are provided and pain medication will be prescribed to you.

You may find eating and speaking difficult. It may take some time to “retrain” your oral musculature and adapt to your improved dental situation. This can sometimes be difficult for patients, and will require patience, perseverance and just practice. You will need to have a liquid diet in the week initially following the surgery, and slowly progress to soft foods. During the three-month healing period, please avoid all hard foods.

A healing period of approximately three months is necessary to allow the implants to successfully osseointegrate into the jawbone, after which the provisional prosthesis is replaced with the final prosthesis.


After confirmation of successful implant healing, your final definitive prosthesis fabrication stages will commence. An update of the digital impression scans is completed, followed by any new design updates. Your input is vital. Your input on the shapes of teeth you like and colours is discussed in more detail and the design plans for your teeth is modified and improved. The design is carefully analysed by our skilled laboratory team to ensure they are perfect before your definitive implant prosthesis is milled and fabricated. After a few try in appointments, once everybody is happy, your new set of teeth are inserted.

As with all dental treatment, there is a finite lifespan of the prosthesis. To maximise the longevity of the prosthesis, as well as any dental treatment completed, it is essential to have optimal home care as well as professional dental maintenance. Careful assessment of the implants and prosthesis at the dentist is required on a routine basis to ensure your mouth is free from infection and the prosthesis cleaned correctly.

Am I a suitable All on 4 dental implant solution candidate?

There are no physical contraindications that would stop a patient from having the All on 4 treatment completed. If patients have significantly reduced bone availability in the upper jaw, they may be prescribed zygomatic implants rather than conventional implants, to assist with their teeth replacement.

Most people are suitable for the All on 4 treatment, especially if you:

  • No longer have any of your natural teeth or are missing teeth

  • Wearing a denture or find wearing dentures uncomfortable

  • Have advanced gum disease or many decayed, damaged teeth

  • Have problems eating a wide range of foods

  • Lack of adequate bone tissue for conventional dental implant procedures

Due to the benefits in look and feel, All on 4 has become a popular alternative to dentures for replacing a full set of teeth. One of the many benefits of the All on 4 cost is the quick turaround, that it enables you to get a new set of teeth in just a 1-3 days. You could have your teeth extracted, then have implants placed on the same day (assuming you dont need a bone graft). 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.

What is Osseointegration?

Osseointegration is where a direct structural and functional connection between living jaw 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 jaw bone and implant. A strong bond is the key to the All on 4 teeth replacement solutions.

Natural Tooth Vs Dental Implant comparison


What is Jaw Bone Resorption?

When you lose some or all of your teeth, you also lose your tooth root which is vital for stimulating your jaw bone. 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 jaw bone resorption as the implant acts as an artificial tooth root, stimulating the jaw bone and maintaining a more youthful appearance. If you already suffer from jaw bone resporation, to be able to proceed with your full teeth replacement, you will likely require bone grafting  so you have enough bone, before your dental implant treatment are placed. Jaw bone resorption is very common amongst users of traditional dentures.


Zygoma Dental Implants for Patients with Severe Jaw Bone Loss

If you have severe maxillary (rear teeth) jaw bone resorption and require a full teeth replacement, Zygomatic implants might be the implants for you. These implants dramatically shorten the total rehabilitation or “time-to-teeth” when compared to other methods to restore a patient’s top jaw bone. The use of Zygoma dental implants eliminates the need for jaw bone grafting.

After a person loses their teeth, and needs teeth replacements, the jaw bone also gets lost over time. When you have a denture, this can place pressure and cause more progressive bone loss. Down the road this can cause severe bone loss and can make the denture no longer fit. Some traditional dental titanium implants may not be an option if the jaw bone loss is this severe. The Zygoma implants were developed especially for these types of cases.

Zygomatic implants are considered to be a relatively new advancement in dental implant technology. They were developed in the late 1990s by the father of dental implantology, Dr. Per Ingvar Branemark. Since their introduction into the dental implant world, they have been gaining popularity for their effectiveness in patients who would otherwise not qualify for dental implant placement.

Consultation and assessment should be completed by a Dental Specialist. These Zygomatic implant treatments is not as common as traditional dental implant treatment and requires an expert with extensive experience and skill.

What Is the Difference Between Zygoma Implants & Traditional Dental Implants?

Zygomatic-and Traditional ImplantsA Zygoma implant is longer than a conventional dental implant. It is still inserted through the mouth, but it anchors into the cheekbone (in the zygomatic bone) as opposed to the dental arches (alveolar bone) in the mouth. Due to the solid bone in the cheeks, Zygomatic implants have a high immediate stability and offer the perfect foundation for immediate placement of replacement teeth.

Zygoma implants are designed to be permanently attached into the cheek bone (zygoma bone) which sits above the upper jaw (maxilla). The Zygoma implants procedure is completed in Aria’s surgery, under IV Sedation. Zygoma implants can provide the foundations needed for a full arch set of screwed in or detachable prosthetic teeth. Zygomatic implants can also be used in coordination with traditional dental implants.

Depending on the patient needs, either 2 (one each side) or 4 (2 each side) implants are placed to support full or partial dental bridges. The procedure is safe, and predictable when performed by a surgeon with experience in the technique, and is provided with sedation options.  When Zygoma implants are used, patients can often have a fixed provisional prosthesis fitted shortly after surgery, avoiding multiple surgeries, and the healing time required with jaw bone grafting.  Just like traditional implants these Zygoma implants will also need a healing period of a few months until the final set of teeth will be fabricated and placed.

Eliminates the Need for Supplemental Procedures

Zygoma Implants Inserted into The Back Of The Jaw

Oftentimes, when dental implants are placed in the upper jaw with low bone mass, supplemental procedures may be necessary. One common procedure is known as a sinus lift, whereby the bone between the oral cavity and sinus cavity is thickened to prevent the implant from damaging the sinuses. Usually, the patient would need to wait until the sinus lift has healed before the dental implants can be placed. With Zygomatic implants, however, there is no need for these supplemental procedures. Not only does this mean less procedures, but it also means that you can get your implants sooner rather than later.

Consequently, the need for a bone graft is often eliminated.

If you have severe maxillary (rear teeth) jaw bone resorption, Zygomatic implants might be the implants for you. These implants dramatically shorten the total rehabilitation or time-to-teeth when compared to other methods to restore a patient’s top jaw bone.
