Dentistry · All-on-4 & All-on-6
Full-arch implant treatment may be considered where most or all teeth in a jaw are missing, or cannot predictably be restored. A transparent guide to how All-on-4 and All-on-6 work, how the choice between them is made — and why neither is automatically “better”.

Full-arch implant treatment replaces a complete row of missing or severely compromised teeth using several dental implants to support a fixed or removable prosthetic restoration. Instead of one implant per missing tooth, a small number of strategically positioned implants carry a full arch of replacement teeth.
All-on-4 uses four implants to support a full-arch restoration in selected cases, often with the back implants angled to make best use of available bone. All-on-6 uses six implants in selected cases, spreading the load across more fixtures. Implant number, implant position, loading protocol and prosthetic design are individually planned — the name of the concept matters far less than the plan behind it.
One honest line matters here: natural teeth should not be extracted simply to make implant treatment possible when they can predictably be preserved. If some of your teeth can be saved, that option is discussed openly before any full-arch plan is agreed.
The decision weighs the number of implants against your bone availability, anatomy, prosthetic design, load distribution, treatment complexity and long-term maintenance. More implants is not automatically better — six implants in poor bone is not superior to four well-placed ones, and vice versa. The treating clinician makes the recommendation from your imaging and examination, and explains the reasoning so you understand why your plan looks the way it does.
Full-arch planning starts with clinical examination and a panoramic X-ray, with CBCT (3D) imaging where indicated — it shows bone height, width and quality, and the position of nerves and sinuses. Just as important is prosthetic planning: the final teeth are designed first, and the implants are positioned to support that result. You can send an existing X-ray before you travel; final planning is confirmed after clinical assessment.
How many trips this means for you — and the gap between stages — is confirmed in your written plan before you book flights, so there are no surprises.
A provisional (temporary) restoration may be fitted while your implants integrate, where implant stability, your bite, the treatment design and the clinician’s judgement allow. The final restoration is a separate, definitive piece of work — stronger materials, refined fit and appearance. Whether a temporary is fixed or removable in your case is part of the plan, not an assumption.
Some patients need additional bone procedures — bone grafting or a sinus lift — depending on anatomy. Angled-implant concepts like All-on-4 can reduce the need for grafting in selected cases, but they do not always avoid it, and no honest assessment promises otherwise. Your imaging decides.
Implant systems referenced through our partner clinic include Straumann, Global D and Medigma BioMedical MARS — no brand is universally “best”; each is selected per case. What matters as much as the brand is documentation: which system and components were used, recorded so your implants are traceable and replacement components remain identifiable wherever you are treated in future. You receive the manufacturer’s warranty documentation for the system used in your treatment.
A full-arch restoration needs daily cleaning — including beneath the prosthesis — plus professional maintenance and monitoring of the gums and implants. Risks include infection, failure of an implant to integrate, peri-implant disease, prosthetic wear and mechanical complications; repairs and maintenance over the years are normal, not a sign of failure. Smoking and poor hygiene raise the risks significantly — the treating clinician is honest about this before treatment, and our team stays reachable 24/7 after you fly home.
The number of implants supporting the full-arch restoration — four or six — and how the load is distributed. Which is appropriate depends on your bone, anatomy and prosthetic plan; neither is automatically better.
From your imaging and examination — bone quantity and quality, anatomy, bite and the design of your final teeth. The recommendation is explained to you with its reasoning, not handed down as a package name.
Where implant stability and your case allow, a provisional restoration may be fitted while the implants integrate. Whether that is fixed or removable for you is confirmed in your plan — same-day fixed teeth are not promised to everyone, because they are not right for everyone.
Bone needs time to integrate around implants, and the honest answer is that it varies — by patient, jaw and case. Your clinician confirms the expected timeline for you; universal healing promises are a warning sign, not a reassurance.
Smoking raises the risk of implant failure and gum problems, so it is weighed honestly in your assessment. Many smokers can still be treated — with clear guidance on reducing risk around surgery and healing — but you deserve the real numbers conversation, not a brush-off.
Options include bone grafting, a sinus lift, or implant positions and angles that make better use of the bone you have. Your CBCT scan decides — which is why serious full-arch planning never skips proper imaging.
Many full-arch pathways involve more than one stage — commonly a surgical visit and a later prosthetic visit — while some cases allow fewer. Your written plan confirms the number of trips and the days needed for each before you book anything.
Send your X-ray or a few photos — the dental team reviews your case and talks you through the honest full-arch options, including whether any of your teeth can be saved.
