If you have a mouth full of failing teeth, or you have been wearing a full denture and wondering whether fixed teeth are possible, you have probably come across the term “All-on-4.” It is one of the most significant advances in implant dentistry in the last two decades — but it is also one of the most heavily marketed, and that marketing does not always give you the full picture.
This guide explains what full-arch implant treatment actually involves, who it genuinely suits, what it costs and why, and what the honest alternatives look like. We will also explain how we approach these cases at Sunny Dental Buderim.
What Full-Arch Implant Treatment Actually Is
A full-arch implant restoration replaces every tooth in either the upper or lower jaw — or both — with a fixed bridge anchored to implants placed in the jawbone.
The most well-known version of this is All-on-4: four implants placed in the jaw, supporting a full-arch bridge. Two implants are placed vertically toward the front of the jaw, and two are angled backward at roughly 45 degrees. That angling is deliberate — it allows the posterior implants to engage denser, better-quality bone further along the arch, and it often avoids the need for bone grafting that straight-placement implants would require in the same area.
Some full-arch restorations use more than four implants — five or six is common, particularly in the upper jaw where bone density and anatomy may call for additional support. The term “All-on-6” reflects this. The underlying principle is the same: a fixed full-arch bridge supported by a small number of strategically placed implants.
What you end up with is a bridge that is permanently attached to the implants — not removable by you at home. It does not come out at night. It does not move. It chews and functions more like natural teeth than any removable option.
There is an important qualification worth making clearly here: the final, permanent bridge is not typically fitted on the day of surgery. After implant placement, a provisional restoration is usually attached while the implants integrate with the bone — a process that takes months. The final, definitive bridge comes later. Marketing language like “teeth in a day” refers to the provisional restoration, not the finished result. Understanding this distinction matters for managing realistic expectations.
Who Full-Arch Treatment Suits
Full-arch implant treatment is genuinely life-changing for the right patients. It is not the right answer for everyone.
It tends to suit:
- People with a failing dentition — multiple teeth that are beyond saving, severely broken down, or already lost — where the clinical question is no longer about saving individual teeth but about replacing the arch as a whole
- Long-term denture wearers who find their denture is increasingly uncomfortable, unstable, or limiting what they can eat, and who want a fixed result
- People who have lost significant bone due to long-term tooth loss but still have sufficient bone for angled implant placement — often without needing grafting first
- Patients who are medically fit for oral surgery and have well-managed general health
It is not always the right option for:
- Patients with active, uncontrolled periodontal (gum) disease. Placing implants in a mouth with active infection significantly increases failure risk. Gum disease must be treated and stable before any implant treatment proceeds — and that may take time.
- Heavy smokers. Smoking impairs healing and is associated with meaningfully higher rates of implant failure and complications. We will not tell you this makes implants impossible, but we will be honest about the increased risk. If you smoke, this is a conversation we need to have openly.
- Patients with certain medical conditions or medications that significantly affect bone healing or immune response — bisphosphonates at higher doses, uncontrolled diabetes, recent radiation to the jaw area. These are not automatic exclusions, but they require careful assessment.
- Patients whose expectations of the outcome do not match what full-arch treatment can actually deliver. Fixed implant teeth are excellent — but they are not identical to natural teeth in every respect, and the maintenance involved is real.
The honest answer to “am I a candidate?” is that it requires a proper clinical assessment, a conversation, and 3D imaging. We cannot tell you over the phone, and we would not try.
Why the Cost Varies So Widely
Full-arch implant treatment in Australia typically ranges from $20,000 to $35,000 or more per arch. For both arches, the combined cost is higher. That is a wide range, and it reflects real variation — not arbitrary pricing differences between practices.
Here is what drives the cost in either direction:
Number of implants. Four implants cost less than six. If your anatomy and bone volume support the four-implant approach, your cost will be lower than a case requiring additional implants for adequate support.
Provisional vs final bridge material. The bridge placed on the day of surgery is typically a provisional — usually made from acrylic or a reinforced resin composite. This is functional but not the final result. The definitive bridge placed after osseointegration is most commonly full-arch zirconia, which is more durable, more aesthetic, and significantly more expensive to fabricate. The difference between a provisional acrylic bridge left in place indefinitely and a milled zirconia final bridge is thousands of dollars.
Extractions. If any remaining teeth need to be removed before implant placement, each extraction is an additional cost. Complex surgical extractions cost more than simple ones.
Sedation. Many patients undergoing a full-arch procedure on the day of surgery prefer to be sedated rather than alert under local anaesthetic alone. Sedation — administered at Sunny Dental by Dwi George RN — is a separate item not included in basic implant fees.
Imaging. 3D cone beam CT scanning is essential for safe full-arch planning. This imaging is typically referred to a radiology centre (we do not have an in-house CT scanner) and is a cost that applies before treatment begins.
Whether bone grafting is needed. One of the advantages of the All-on-4 technique is that angling the posterior implants can sometimes avoid the need for grafting. But not every patient is a no-graft case — if your anatomy does require preparatory bone work, that adds both cost and time to the treatment.
Understanding which of these factors apply to your case is exactly what a consultation and proper planning are for. A treatment plan with itemised costs before any commitment is not optional — it is the only responsible way to approach treatment at this scale.
The Alternatives: What the Spectrum Looks Like
Full-arch implant treatment sits at one end of a spectrum of options for replacing a full arch of teeth. It is worth understanding where it sits relative to the alternatives, both in terms of outcome and cost.
Conventional full denture — the traditional removable option. No implants, lowest cost. The denture rests on the gum and is held in place by suction and ridge anatomy. Bone loss continues beneath it over time. Cost varies by material and laboratory, but a high-quality complete denture typically costs $1,500–$3,500 per arch. It is the most accessible option and the right choice for some patients.
Implant-retained overdenture — a removable denture that clips onto two to four implants. The denture is still removed for cleaning, but the implants dramatically improve stability and reduce movement during eating and speaking. The implants also slow bone loss under the denture. Typical Australian cost range: $8,000–$18,000 depending on the number of implants, the attachment system, and the denture itself. This is an excellent middle-ground option for many patients.
Fixed full-arch bridge (All-on-4 / All-on-6) — the implant-supported fixed option covered in detail above. Typical Australian cost range: $20,000–$35,000+ per arch. Highest cost, highest function, closest to natural teeth in terms of daily experience.
The right option depends on your clinical situation, your priorities, and your budget — and we will talk through all of them honestly. We will not push you toward the most expensive solution if a simpler one meets your needs well. We will also not recommend a cheaper option that we genuinely believe will not serve you well over time.

How We Approach Full-Arch Cases at Sunny Dental
Full-arch treatment is the most technically demanding work in restorative implant dentistry. How a practice plans and executes this treatment matters — not just for the result, but for your safety.
Digital planning with intraoral scanning and surgical guides. We use intraoral scanning to capture precise digital impressions of your mouth. This feeds into digital treatment planning software that allows us to plan implant positions on a 3D model of your jaw, generated from your cone beam CT scan. From this plan, we produce a surgical guide — a custom-fabricated device used during surgery to place the implants in exactly the positions planned digitally. This is not just more precise than freehand placement; it is more predictable and safer.
Cone beam CT is referred out. We refer patients for 3D CT scanning at a specialist radiology centre. The scan is then used in our planning software. We do not have an in-house CT scanner, and we will not tell you otherwise.
Written treatment plan with itemised costs before you commit to anything. Before treatment begins, you receive a written plan that specifies every procedure involved, the timeline, and the itemised cost for each component. There are no surprises. If the full plan is beyond what you want to proceed with, we discuss alternatives — there is never any pressure.
Honest assessment of your case complexity. Dr Louis George and Dr Jeremy Collins are general dentists — experienced and capable in implant dentistry, but not oral and maxillofacial surgeons or periodontists. Complex full-arch cases that fall outside the scope of general dentistry — whether due to anatomy, medical complexity, or the degree of surgical intervention required — are referred to trusted colleagues. We will always tell you when we think referral is the right call, and why.
Sedation is available. For patients who prefer to be sedated during a full-arch procedure, Dwi George RN administers and monitors sedation throughout the appointment. This is genuine clinical sedation with a registered nurse present — not a compromise.
Health Funds, DVA, and Managing the Cost
Bupa Members First. Sunny Dental Buderim is a Bupa Members First provider. This means Bupa members with eligible extras cover can claim their Bupa benefit here, and the Members First arrangement gives them access to the maximum Bupa rebate available. The actual rebate depends on your policy, your annual limits, and how much of your annual major dental benefit has already been used. Call Bupa directly before your consultation and ask about item numbers 311 (implant fixture) and 375 (implant crown) — knowing your limits helps you plan.
Other private health funds. Sunny Dental accepts all major health funds. Rebates vary by fund and policy. Most mid-to-higher-level extras policies include a major dental benefit, but annual limits (commonly $1,000–$3,000) mean they cover a portion of full-arch treatment costs rather than most of it.
DVA. We are a DVA-friendly practice. Gold Card holders may have access to clinically necessary dental treatment including implants, subject to assessment and, in some cases, prior approval. White Card coverage is more limited. Bring your card to your consultation and we will work through the DVA pathway with you. Dr Louis George’s background as a former Royal Navy dentist means he has a genuine understanding of veterans and the specific health histories that can accompany military service.
Payment options. If spreading costs over time is important to your planning, raise it at your consultation. We can explain the options available to you without committing you to anything.
Frequently Asked Questions
How long does the full-arch process take from start to finish?
Longer than most people expect, and it is worth being honest about this. From initial consultation to the final definitive bridge, the process typically spans six to twelve months, and sometimes longer. Implants need three to six months to integrate with bone before the final bridge can be fitted. If preparatory procedures like extractions or bone grafting are needed first, that adds further time. Arriving with realistic expectations about the timeline makes the process smoother.
Is All-on-4 permanent?
The implants themselves, once integrated, are designed to be long-term. The bridge attached to them is not a consumable — a well-made zirconia bridge, well-maintained, can last many years. But like any dental restoration, it is not unconditional. The long-term outcome depends significantly on maintenance: cleaning around and under the bridge, regular professional hygiene appointments, and avoiding habits (heavy grinding, hard impacts) that put undue stress on the restoration.
Does it hurt?
The surgery is performed under local anaesthetic, and sedation is available for patients who want it. Post-surgical discomfort varies between patients — most describe the recovery as manageable with standard pain relief for the first few days. We will give you clear post-operative instructions and contact details if you have concerns after the procedure.
What happens if an implant fails?
Implant failure — where an implant does not integrate or is lost after a period of function — does occur. The overall success rates for implants are high, but they are not 100%, and patients should understand this before proceeding. Smoking, poorly controlled medical conditions, and inadequate oral hygiene are the major risk factors within a patient’s influence. Your written treatment plan will outline the risks specific to your case.
Can I eat normally with an All-on-4 bridge?
The full-arch bridge functions far better than a conventional denture for most foods — this is one of the primary reasons patients choose fixed implant treatment. However, it is not identical to natural teeth, and very hard foods (cracking nuts with your teeth, hard candy, ice) can risk fracture of the bridge material. We will give you specific guidance on what to eat during the provisional phase, and what to be mindful of with the final restoration.
What does the cleaning routine look like?
Cleaning under and around a full-arch bridge requires more than a standard brush and floss. Water flossers, interdental brushes, and specific flossing techniques are part of the long-term maintenance routine. We will show you exactly what is required. Regular professional hygiene visits are also essential — not optional — to keep the gum tissue around the implants healthy and catch any early signs of peri-implantitis.
