All On 4 Dental Implants

All on 4 Plus Zygoma – When There Is Significant Bone Loss

For patients with severe bone loss in the upper jaw — which is a common long-term consequence of tooth loss — zygomatic implants may offer a path forward where other options fall short.

Instead of anchoring into the upper jawbone (which may have lost significant density), zygomatic implants are placed into the cheekbone (the zygomatic bone). The zygomatic bone is dense and generally unaffected by the bone resorption that follows tooth loss.

This approach can make a fixed full-arch result achievable for patients who would otherwise need multiple rounds of bone grafting before implant treatment could even begin — a process that can add months to the treatment timeline and considerable cost.

FY Smile offers All on 4 zygomatic implant treatment for patients with significant upper jaw bone loss. This is a specialist area of implant dentistry, and a detailed clinical assessment is needed before any plan is developed.

The All on 4 Treatment Process – Step by Step

Every patient’s journey is slightly different, but here is how the All on 4 treatment process typically unfolds at FY Smile. The timeline below is a general guide — your treating dentist will give you a clearer picture of your own expected timeline during the planning stages.

1. Step 1: Consultation and Planning
   Your first appointment is a thorough clinical assessment. FY Smile team takes 3D CBCT scans, photographs, and reviews your medical and dental history in detail. This is where the treatment plan is built specifically for you — not a template. You will leave this appointment with a clear understanding of what your plan involves and a written treatment breakdown to review.
2. Step 2: Treatment Plan Review
   You will meet with Dr Fadi Yassmin to go through the proposed plan in full. This is your opportunity to understand the timeline, ask any questions, discuss sedation options, and make sure you feel confident before any commitment is made.
3. Step 3: Surgery Day – Implant Placement and Temporary Teeth
   On surgery day, any remaining failing teeth are extracted, the four implants are placed into the prepared sites, and a temporary fixed bridge is attached to the implants — all in one appointment. You leave the clinic with a full set of teeth fixed to the implants. You are not without teeth at any point.
4. Step 4: Healing and Osseointegration
   Over the following 3 to 6 months, the titanium implants fuse with the surrounding jawbone. This process is called osseointegration. During this time, you will be on a modified diet (no hard, crunchy, or chewy foods) and will attend scheduled review appointments with the FY Smile team to monitor how healing is progressing.
5. Step 5: Fitting Your Permanent Bridge
   Once the implants are confirmed to have integrated successfully, the temporary bridge is removed and your final permanent restoration is fitted. This is typically a custom-made zirconia or porcelain bridge, designed and colour-matched during the planning phase to suit your face and your goals.

For patients who are anxious about dental procedures, FY Smile offers conscious sedation. This allows you to be deeply relaxed throughout the surgical phase without requiring a general anaesthetic and an overnight hospital stay.

What Does an All on 4 Bridge Look Like?

The All on 4 bridge is a full-arch prosthesis — a complete set of teeth for either your upper or lower jaw — attached permanently to the four implant posts. It is custom-made to fit your mouth and to match the aesthetic goals agreed during your planning consultations.

Modern All on 4 bridges are made from materials including:

• Zirconia: A ceramic material that is extremely strong, highly aesthetic, and resistant to chipping. This is a common choice for the permanent bridge at FY Smile.
• Acrylic (provisional): Used for the temporary bridge during the healing phase. This is functional and fixed, but will be replaced with the final restoration later.
• Hybrid porcelain: Combines a strong metal or zirconia substructure with porcelain teeth, delivering a highly natural look with excellent durability and life like translucency.
• PMMA (polymethyl methacrylate): A high-grade dental polymer often used for long-term provisional bridges, or as a lighter, more cost-effective permanent option. It’s easier to adjust and repair than zirconia, and still looks great.

At FY Smile, the design of the final restoration is informed by principles from Digital Smile Design and facially-driven dentistry. The goal is a result that suits your face, your proportions, and your personality — not a generic, one-shape-fits-all tooth form.

All on 4 Dental Implant Recovery – What to Expect

One of the most common topics patients want to understand clearly before committing to All on 4 is recovery. Here is an honest overview of what the post-surgery period typically looks like.

• Days 1–3
  Most discomfort and swelling occurs in the first 72 hours. Pain is managed with prescribed medication and is generally well-controlled for most patients. Swelling around the face and jaw is normal and typically peaks around day two to three before gradually settling.
• Days 4–14
  Swelling and discomfort reduce noticeably in this period for most patients. A soft-food diet is maintained throughout. Smoothies, yoghurt, soup, mashed vegetables, and soft fish are common foods at this stage. Hard, crunchy, or chewy foods are completely off the table.
• Weeks 2–8
  Most patients are back to their normal daily activities within the first week after surgery, though physical exertion and heavy lifting should be avoided for longer. At this stage the jaw is still in the early phases of healing and the implants are beginning to integrate.
• 3–6 Months: Osseointegration
  The implants are fusing with the bone during this period. Scheduled review appointments with the FY Smile team are an important part of monitoring progress. The temporary bridge is functional during this time but requires care.
• After the Permanent Bridge Is Fitted
  Long-term care involves twice-daily brushing with a soft-bristle toothbrush and fluoride toothpaste, cleaning along the gum line and around each implant connection, and using a water flosser or interdental brushes to clean beneath the bridge. Regular professional cleans with the hygiene team are an essential part of long-term implant maintenance.

Common Mistakes to Avoid with All on 4 Treatment

These are the most frequent issues that can affect All on 4 outcomes — knowing them in advance puts you in a much better position.

1. Choosing a Provider Based on Price Alone
   All on 4 is a surgical procedure that requires specialist skills, quality materials, and careful planning. The lowest quote does not always reflect the quality of what is included. Before choosing a provider, ask about the qualifications and experience of the treating dentist, the materials used for the final bridge, and what aftercare is included in the quoted fee.
2. Not Disclosing Your Full Medical History
   Certain medications (such as bisphosphonates) and medical conditions (such as poorly controlled diabetes) can affect implant integration and healing. Your FY Smile dentist needs a complete picture of your health before planning treatment. Withholding information — even if it seems unrelated — can affect your outcome and your safety.
3. Not Following the Post-Surgery Diet
   Returning to a hard or chewy diet too soon puts mechanical stress on the implants before they have integrated. This is one of the preventable causes of early implant complications. Follow your dentist’s dietary guidelines carefully for the full recommended period.
4. Skipping Review Appointments
   The healing phase check-ups at FY Smile are not optional extras. They allow the team to confirm integration is progressing well, identify any early issues, and adjust the plan if needed. Skipping appointments means problems may be caught later rather than earlier.
5. Neglecting Long-Term Oral Hygiene
   All on 4 implants are not maintenance-free. Patients who do not maintain daily oral hygiene or attend regular professional cleans are at risk of developing peri-implantitis — an infection around the implant that, if left untreated, can lead to implant failure. Long-term implant health depends on consistent care at home and at the clinic.

All on 4 vs Other Tooth Replacement Options

Here is how All on 4 dental implants compare to the two most common alternatives — conventional full dentures and individual dental implants.

“How much do All on 4 dental implants cost in Sydney?” is one of the most common questions people ask — and it deserves a direct answer.

The honest answer is: it depends on your situation. All on 4 is not a standardised, off-the-shelf procedure. The cost of your treatment is determined by a range of clinical and material factors that differ from patient to patient.

Factors That Affect All on 4 Cost

• Whether you need one arch (upper or lower) or both arches treated
• Whether extractions, bone grafting, or other preparatory work are required
• The type of material used for the final bridge (zirconia, acrylic hybrid, PFM)
• Whether conscious sedation is required for surgery
• The complexity of your individual anatomy and clinical case

Can Medicare or Private Health Insurance Help?

Medicare does not typically cover elective dental implant procedures. Some private health insurance policies with major dental cover may contribute a portion — the amount varies significantly between funds and policies. It is worth contacting your health fund directly using the specific item numbers your treating dentist provides after your assessment.

Payment plan options may also be available. This is worth discussing with the FY Smile team at your consultation appointment.
