What Are All on 4 Dental Implants? (All on Four Explained)
The All-on-4 technique is designed for patients missing all or most of their upper or lower teeth. Four implants are placed, two upright at the front and two angled at the back, to support a fixed full-arch bridge of up to 12 teeth. Unlike traditional methods that require six to ten implants, All-on-4 maximises available bone and avoids sensitive structures like the sinus or nerve canal. In most cases, patients receive a fixed provisional bridge on the same day as surgery.
All on 4 Dental Implants for Upper and Lower Jaw
All on 4 dental implants can be placed in the upper jaw (maxilla), the lower jaw (mandible), or both arches simultaneously.

All on 4 Dental Implants for the Lower Jaw
All on 4 dental implants for the lower jaw are often the more straightforward of the two arches because the lower jaw typically has sufficient bone density and is further from the sinuses. The procedure follows the same technique, placing four implants to support a full arch lower bridge.

All on 4 Dental Implants for the Upper Jaw
All on 4 dental implants for the upper jaw require careful planning to avoid the sinus cavities. In cases where the upper jaw has insufficient bone height, a sinus lift or zygomatic implants may be considered. Dr Kristian van Mourik assesses each case individually to determine the most appropriate approach.
Problems Caused By Missing Teeth
Tooth loss affects both oral health and overall wellbeing. Many Sydney patients choose All on 4 dental implants for full arch teeth replacement after experiencing one or more of the following problems.
Difficulty chewing
Missing teeth can make it harder to eat comfortably and may affect diet choices.
Changes to speech
Spaces in the mouth sometimes alter the way words are pronounced.
Bone loss
Without tooth roots, the jawbone can gradually shrink, affecting appearance and limiting future treatment options.
Shifting of nearby teeth
When a tooth is missing, surrounding teeth can drift into the space, changing bite alignment and increasing wear.
Jaw strain and imbalance
An uneven bite places extra pressure on the jaw joints (TMJ), sometimes leading to pain or stiffness.
Reduced confidence
Missing teeth can make people feel self-conscious about smiling or eating in public. Replacing them helps restore a natural look and confidence.
How Do All on 4 Compare to Alternatives?
All on 4 dental implants offer several advantages over traditional implants and removable dentures. The comparison below covers the key reasons Sydney patients choose the All on Four procedure as their preferred full arch teeth replacement option.
Practicality
All On 4 implants are simple to care for and highly functional. They can be cleaned just like natural teeth—by brushing twice daily and using a proxy brush and unwaxed floss to maintain oral hygiene.
Strength & Durability
All on 4 dental implants are designed for long-term results and permanent stability. The all on 4 bridge lasts 10 to 20 years with proper care, and the titanium implants themselves typically remain stable for a lifetime. Unlike dentures that require nightly removal, All on 4 provides a fixed, lasting solution.
Aesthetic Appeal
Crafted from premium monolithic zirconia and porcelain, All On 4 implants offer a beautiful, natural-looking smile that is both durable and visually appealing.
Versatility
All On 4 implants are suitable for a wide range of patients, including many who are not candidates for traditional implants. They can be a strong option for long-time denture wearers and those with atrophic jaws.
Important Considerations
While All On 4 implants are highly versatile, they may not be suitable for everyone. Factors such as teeth grinding, smoking, or certain medications could affect your eligibility. Dr van Mourik will assess your individual needs and recommend the best option for your case.
Why Choose an Oral and Maxillofacial Surgeon for All-on-4?
All on 4 dental implant surgery is one of the most complex procedures in modern dentistry. Placing four implants to support a full arch teeth replacement requires a precise understanding of bone anatomy, surgical technique, and complication management.Â
Not all practitioners offering All-on-4 in Sydney hold the same level of training. Many are general dentists or practitioners with short-course implant certification. An Oral and Maxillofacial Surgeon is different.
Is a Specialist Better for All-on-4?
Yes. An Oral and Maxillofacial Surgeon (OMS) is the most highly trained specialist you can choose for All-on-4 treatment. To become a qualified OMS in Australia, a surgeon must complete both a dental degree and a medical degree, followed by a minimum of five years of specialist surgical training accredited by the Royal Australasian College of Dental Surgeons (RACDS).
This means an OMS is simultaneously a doctor, a dentist, and a surgeon. There are only a small number of fully qualified Oral and Maxillofacial Surgeons in Sydney performing All-on-4 at this level.
Dr Kristian van Mourik is a Fellow of the Royal Australasian College of Dental Surgeons and one of Sydney’s most experienced OMS specialists. He has performed All on 4 dental implant surgery for patients across Sydney, including complex cases involving significant bone loss.
What This Means for Your Treatment
Greater surgical precision: Dr. Kristian van Mourik uses advanced 3D imaging and digital planning to map All on 4 implant placement before any incision is made. This level of pre-surgical planning reduces risk and improves long-term outcomes for all on 4 dental implant surgery.
Access to a private hospital and general anaesthetic Unlike many dental clinics, Dr van Mourik operates in an accredited day hospital facility. For patients who prefer to be fully asleep during their procedure, general anaesthetic is available, administered by a Fellow of the Australian and New Zealand College of Anaesthetists (FANZCA). This is a standard of care that most dental practices simply cannot offer.
Complex cases welcome Patients who have been told elsewhere that they are not suitable candidates for All-on-4 due to significant bone loss are encouraged to consult with Dr van Mourik. As an OMS with specialist training in bone grafting and zygomatic implants, he can often provide solutions that fall outside the scope of a general dental practice.
Specialist management if complications arise Complications from All-on-4 are uncommon but can occur. When they do, having a fully qualified surgeon who is also a medical doctor means you are in the safest possible hands. Dr van Mourik has the surgical training and hospital access to manage complications at the highest level.

All on 4 Dental Implants Before and After

Before All on 4 Treatment
Before All on 4 dental implants, Dr. Kristian van Mourik completes a full diagnostic assessment including cone beam CT scans, 3D jaw modelling, and a review of your dental and medical history. Any remaining teeth that cannot be retained are extracted. Bone volume and density are assessed to confirm whether All on 4 is appropriate or whether zygomatic implants or bone grafting is required.

After All on 4 Treatment
After All on 4 dental implant surgery, patients receive a provisional bridge on the same day or within a few days. The full, final all on 4 bridge is fitted once osseointegration is confirmed at 3 to 6 months. Most patients describe the result as transformative, with restored chewing ability, improved confidence, and a natural-looking smile.
How Long Do All on 4 Dental Implants Last?
With good oral hygiene and regular professional cleans, All on 4 dental implants can remain strong and functional for decades. The titanium implants typically stay stable for a lifetime as long as the surrounding bone remains healthy. In rare cases, all on 4 implant failure can occur due to infection, bone loss, or poor healing. A replacement implant can often be placed once healing is complete. The all on 4 bridge attached to the implants typically lasts 10 to 20 years depending on materials and care
Longevity starts with surgical expertise. Dr. Kristian van Mourik is a specialist Oral and Maxillofacial Surgeon with advanced training in All on 4 dental implant surgery in Sydney. He works exclusively with Straumann and Nobel Biocare, two of the most trusted implant systems in the world, to deliver natural-looking, durable results.
All on 4 Sydney - Step by Step Treatment Process
All on 4 dental implant surgery requires expert planning and surgical precision. Dr. Kristian van Mourik guides each patient through the full All on 4 procedure from initial consultation through to final bridge fitting. The following is an overview of what to expect at each stage
Step 1: Consultation
At your first visit, Dr. Kristian van Mourik assesses your teeth, gums, bone structure, and nerve pathways using X-rays and 3D cone beam scans. Your medical history is reviewed to confirm whether All on 4 dental implants in Sydney are appropriate for your case. A detailed treatment plan and all alternatives are discussed.
Step 2: Treatment Planning
Using advanced software, Dr Van Mourik plans precise implant placement to ensure maximum bone support and avoid vital structures. Your custom-designed bridge will be crafted to restore a natural look and feel.
Step 3: Implant Placement
The four All on 4 implants are placed during a surgical procedure, usually under local anaesthesia at Dr. Kristian van Mourik's practice. For complex cases or patients who prefer to be fully asleep, general anaesthetic at an accredited Sydney day hospital is available, administered by a Fellow of the Australian and New Zealand College of Anaesthetists.
Step 4: Healing & Final Bridge
Over 3–6 months, the implants fuse with the jawbone (osseointegration). A healing cap is placed after one month to shape the gum. Once healed, your referring dentist will fit the permanent set of false teeth, and you'll be shown how to care for your new All-on-4 teeth.
How long does All on 4 surgery take?
A single All-on-4 Sydney arch can often be placed in 1–2 hours. Complex cases may take longer, especially if bone grafting is required.
Will I be awake during the procedure?
Most patients stay awake and comfortable with local anaesthesia. For those with anxiety or complex needs, Dr Van Mourik offers sedation or general anaesthesia with certified FANZCA anesthetists for maximum safety and comfort.

How to Look After All on 4 Dental Implants
Plaque can build up on All-On-4® bridges just like natural teeth. Daily cleaning helps prevent staining, bad breath, and more serious issues like peri-implantitis, a gum condition that can affect implants. With the right care All on 4s can last a lifetime.
Daily Oral Hygiene
- Brush twice a day: Use a soft-bristled toothbrush to gently clean your implant bridge, gums, and tongue. This helps prevent plaque and bacteria buildup.
- Floss daily: Choose implant-specific floss or an interdental brush to reach under the bridge and around the implants where food can get trapped.
- Antibacterial mouthwash: Rinsing once a day helps reduce bacteria and supports healthy gums.
- Water flosser option: A water flosser or Waterpik can be especially helpful for clearing debris from hard-to-reach spots.
Professional Care
Routine check-ups: Visit your dentist regularly, usually every six months, for professional cleanings and to maintain implant health.Â
Diet & Lifestyle
- Mind your diet: Avoid hard, sticky, or chewy foods that may stress or damage the implant bridge.
- No smoking: Smoking can slow healing, increase rise of gum disease and implant failure.
- Night guard protection: If you grind or clench your teeth, wearing a night guard helps protect your implants from excessive pressure.

What Does Corrective Jaw Surgery Involve?
The following is an overview of what double jaw surgery and corrective jaw surgery involve, from pre-surgical preparation through to recovery. The procedure is performed at a private Sydney hospital by Dr. Kristian van Mourik as a specialist Oral and Maxillofacial Surgeon.
Pre-Surgery Preparation
Before corrective jaw surgery, Dr. Kristian van Mourik completes a full diagnostic assessment including cone beam X-rays and 3D jaw modelling. Orthodontic preparation may be required to align the teeth before surgery. Virtual surgical planning is used to map the procedure and create custom surgical plates and guides.
On the Day of Surgery
Corrective jaw surgery is performed mostly inside the mouth, leaving no visible external scars. In rare cases a small incision is placed within a natural skin crease. Precise bone cuts (osteotomies) are made, the jaws are repositioned and secured with titanium plates and screws. In some cases, bone grafting is performed to enhance the jaw profile
During Surgery
- Incisions: Most surgery is performed inside the mouth, leaving no visible scars. Rarely, small external incisions are needed, which Dr van Mourik places within natural skin creases to minimise visibility.
- Bone Repositioning: Precise bone cuts (osteotomies) are made, and the jaws are repositioned. They are fixed securely with titanium plates and screws.
- Bone Grafting (if required): Occasionally, bone grafting is performed to enhance jaw profile.
After surgery and healing
- Bone Healing: The jawbone heals over a period of 6–8 weeks.
- Plates and Screws: Titanium plates and screws remain permanently in place.
- Post-Surgical Orthodontics: Minor orthodontic adjustments may be needed, usually beginning about 6 weeks after surgery.
