On four implants.
All-on-4 is a revolutionary full-arch implant technique that restores an entire upper or lower jaw using just four strategically placed implants — eliminating the need for bone grafting in most cases and often providing provisional teeth on the same day as surgery.
A complete arch of teeth supported by just four titanium implants
All-on-4 uses four implants per jaw — two placed vertically at the front, and two placed at an angle of up to 45° at the rear — to distribute bite forces across the arch. This angled placement allows implants to be positioned in areas where bone density is higher, avoiding the major sinuses and nerves that often limit conventional implant
placement.
The technique was developed to provide a fixed, immediately loadable full-arch restoration for patients who have lost most or all of their teeth, or who face full arch extraction. A full set of fixed provisional teeth can often be fitted on the same day as surgery, with the final porcelain restoration placed after full healing.
- Full upper or lower arch tooth loss — Restoring all teeth in an arch with a permanent, fixed, implant-supported solution
- Failing dentition requiring full extraction — All-on-4 planned in conjunction with the extraction — one surgical appointment, new teeth the same day
- Existing denture wearers — Converting from a removable denture to a permanently fixed implant-supported arch
- Patients who want to avoid bone grafting — Angled implant placement in denser bone areas eliminates the need for grafting in most cases
- Edentulous patients — Restoring a jaw that has been without teeth for some time — All-on-4 can work even with some bone resorption
Traditional full arch restoration using 6–8 individual implants often requires bone grafting and a longer treatment timeline. All-on-4 achieves a comparable outcome with 4 implants, less surgery, lower cost, and in many cases same-day provisional teeth. It is particularly effective for patients with moderate bone loss in the posterior
jaw.
for you?
All-on-4 is designed specifically for patients who have lost or are losing all their teeth in one or both arches — or who are planning full arch extractions.
The angled implant design was developed specifically for patients with bone loss in the back of the jaw — avoiding the need for sinus lifts or major grafting procedures.
Patients who have worn a removable denture for years and want a permanent fixed solution that feels and functions like natural teeth are ideal All-on-4 candidates.
All-on-4 is major oral surgery performed under sedation or GA. Good cardiovascular health and absence of uncontrolled systemic disease is required — assessed at consultation.

Full CBCT imaging of both jaws. Dr Kozor plans the exact implant positions, lengths, and angles using 3D planning software. Surgical guides fabricated for precision placement.
Implant placement surgery under sedation or GA. Provisional fixed arch fitted on the same day in most cases — you leave with teeth. Recovery 5–7 days.
Full osseointegration occurs over 3–4 months. The provisional arch is worn throughout and modified as the implants heal. Soft food diet recommended for the first 3 months.
Once fully integrated, the provisional is replaced with the final high-strength porcelain-fused arch — custom shade- matched, shaped, and designed to restore your full smile permanently.

The angled rear implants engage denser bone in areas that avoid sinus cavities — eliminating the bone grafting required for conventional full-arch implant approaches in most patients.
In most cases, a fixed provisional arch is fitted on the same day as implant surgery. You leave the clinic with a full set of teeth — never without a smile throughout your treatment.
All-on-4 provides a fixed, permanent, full arch of teeth that looks and functions like natural dentition. It restores full bite function, prevents bone loss, and eliminates every limitation of removable dentures.

Thinking about all-on-4 dental implants? Here are the questions we hear most. Call us if yours isn’t here.
Is All-on-4 painful?
No. The procedure is performed under local anaesthetic, with sedation available if needed. Mild discomfort and swelling after surgery are normal and usually improve within a few days.
How much does All-on-4 cost in Sydney?
The cost varies depending on your treatment needs, the number of arches being treated, and whether additional procedures are required. Your dentist will provide a personalised quote after your consultation.
How long does All-on-4 last?
With proper care and regular dental check-ups, the implants can last 20 years or more, while the replacement teeth may need maintenance or replacement over time.
Can I eat normally with All-on-4?
Yes. After the initial healing period, most patients can return to eating a wide variety of foods comfortably and confidently. Your dentist will guide you on what to eat during recovery.
