Missing or failing teeth? You've probably already tried a few things that didn't stick – and you aren’t alone in that. 

If you’ve found yourself avoiding certain foods, skipping photos, putting off a fix for your teeth that felt too big or too expensive. This guide is for you. It covers the most common full-arch options honestly, including why All-on-4® tends to be the right call for most people.

Full Arch Option How It Works Pros Considerations Typical Longevity
All-on-4® Dental Implants Four implants support a fixed full arch of teeth Permanent, strong, fewer implants needed Requires experienced surgical planning Designed to last decades or lifetime
All-on-6 Dental Implants Six implants support a full arch Extra stability and load distribution May require more bone density Designed to last decades or lifetime
Mini Dental Implants Small diameter implants support dentures Lower upfront cost, simpler procedure Less durable, often temporary solution Often several years
Implant-Supported Dentures Dentures snap onto implants More stable than traditional dentures Removable, can still feel bulky 5-10 years for denture components
Traditional Dentures Removable prosthetic teeth Lowest upfront cost Bone loss, slipping, frequent replacement 5-8 years

Why "Just Fixing a Few Teeth" Usually Isn't Enough

It's tempting to think about dental problems one tooth at a time. But extensive decay, bone loss, and deteriorating teeth rarely stop at one or two. For many people, the entire arch — or both arches — are compromised. Treating individual teeth often becomes a cycle: fix one, lose another, repeat.

Full-arch replacement breaks that cycle entirely. You aren’t paying for patchwork dentistry to fix a tooth here and there. Instead, you replace the failing system all at once. A full set of new teeth anchored securely into your jaw gives you back something that feels and functions like natural teeth — often permanently.

That's a fundamentally different outcome than what any traditional temporary solution can offer.

Traditional Solutions That Are Typically Temporary

Before diving into full-arch options, it's worth understanding why so many people who tried conventional approaches are now looking for something better.

Removable dentures have been around for generations — and so have their drawbacks. They rely on suction, adhesive paste, or clasps to stay in place, none of which are usually reliable. 

Slipping during meals or conversation is common. Over time, bone loss beneath the gums is likely to accelerate without tooth roots to stimulate it, meaning the fit of the denture often gets worse and the jaw usually continues to change shape. Many patients describe dentures as a constant reminder of what they've lost.

Dental bridges replace individual missing teeth by anchoring to neighboring healthy teeth — which typically must be ground down to support the bridge. You're essentially sacrificing good teeth to support the failing ones. Bridges also don't address bone loss, and they typically need to be replaced every 10–15 years.

This isn’t a full-arch solution because it relies on healthy teeth.

Snap-in (implant-retained) dentures are a step up from traditional dentures— they click onto a few implants for better stability. But they're still removable. You still take them out. You still clean them separately. It still isn’t likely to compare to having healthy, natural teeth.

For anyone dealing with extensive tooth loss or a full arch of failing teeth, these traditional solutions share a common flaw: they aren’t designed to last forever and often need to be re-done.

Full-Arch Implant Solutions: The Options Explained

Full-arch implant procedures replace an entire upper or lower set of teeth with a fixed, non-removable prosthesis supported by dental implants. Here's a clear breakdown of each approach.

All-on-4®: The Gold Standard for Most Patients

All-on-4® is an extremely common full-arch implant procedure and is often ideal for many patients. Four strategically placed implants — two in front and two angled in the back — support a full arch of teeth. The angled placement allows the rear implants to use denser bone.

This means many patients qualify even if they've experienced significant bone loss in other parts of the jaw.

What makes All-on-4® the gold standard:

  • Fewer implants required — Instead of replacing each tooth individual, All-on-4® minimizes surgical complexity while still creating a stable foundation for new teeth.
  • Works even with bone loss — the angled technique avoids areas of poor bone density that could disqualify patients from other procedures
  • Permanent and fixed — the teeth are fixed in place. They don’t rely on a snapping mechanism or glue to hold them in. It isn’t designed to be removed by anyone other than a qualified dental professional.
  • Long-term track record — Years of research and millions of dollars have been invested into the process that is now All-on-4® and permanent teeth in 24 hours. Not only is the process research backed, it is proven to work and be safe as Nuvia does hundreds of these cases day in and day out. Nuvia’s success rate (which is higher than most) is {{success_rate}}.
  • Permanent teeth in 24 hours* — most patients leave with a full set of functioning teeth within 24 hours of surgery

* Nuvia has developed a process that makes it possible for patients to get their new set of permanent teeth just 24 hours after surgery, unlike “teeth in a day” methods that can have patients waiting in a temporary set of teeth for up to 10+ months. 

Nuvia’s proprietary approach isn’t common because it takes a highly coordinated team, in-house lab, and dedicated professionals that do this day in and day out.

All-on-6®: Maximum Strength for Complex Cases

All-on-6® follows the same principle as All-on-4® but uses six implants to support the arch. That additional support distributes bite force across more points, which can be advantageous for patients who have excellent bone volume and density, have strong bite forces (common in back-tooth chewers), or are replacing a heavily used arch where maximum stability is a priority.

When All-on-6 may be preferred:

  • Situations where additional implants make for a stronger foundation for a new set of teeth
  • Cases where the provider/surgeon determines having extra support would be beneficial.

All-on-6® is not inherently "better" than All-on-4® — it's just a different option for specific anatomical situations. More implants can mean greater complexity and cost, which is why it's recommended only when a provider feels it’s needed.

All-on-4 All-on-6
Implants used 4 6
Best for Most full-arch patients, including those with some bone loss Patients with strong bone density, high bite force
Bone grafting typically needed? Rarely — angled placement avoids poor bone Rarely — good bone required
Same-day teeth Yes Yes
Permanent and fixed Yes Yes
Relative cost Lower Higher
Success rate Excellent Excellent

It’s important to remember when it comes to full arch restorations, as a patient you aren’t choosing between All-on-4® and All-on-6®. Rather, an experienced provider can give you guidance on which method best fits your situation.

Mini Implants: A Budget Option With Real Limitations

Mini implants are smaller in diameter than traditional dental implants.

They are often used to stabilize dentures rather than support a permanent bridge of teeth.

While mini implants may have a lower upfront cost, they are typically considered a less durable option for full arch replacement. Because of their smaller size, they generally cannot support the same biting forces as full-size implants.

For patients seeking a long-term, permanent solution, mini implants are usually not the preferred choice.

Zygomatic Implants: For More Complex Cases and Bone Loss

Zygomatic implants are longer implants anchored in the cheekbone (zygoma) rather than the jaw. 

They exist to serve patients with severe upper jaw bone loss who aren't candidates for any other approach — including All-on-4®.

This is a complex procedure performed by expert, highly trained surgeons. It's not a first-line option, but it means that there may still be hope for patients who have extreme bone loss and/or have been turned down for treatment by other providers. 

Nuvia’s oral surgeons and restorative dentists restore smiles with full arch dental implants day in and day out. If you’re looking for a second opinion from experts qualified for complex cases, take the 60-second quiz. A new smile with permanent teeth in 24 hours may be possible for you.

Why All-on-4® Works for Most People

If you're a candidate and want to stop worrying about your teeth, All-on-4® dental implants is likely the right path.

Implant-secured teeth don't come out. You stop thinking about them at dinner, in conversations, in meetings. They become part of you.

They also preserve your jawbone in a way removable options don't — which protects your facial structure over time.

Nuvia's zirconia teeth and implants are designed to last a lifetime. When you factor in years of denture replacements, bridge repairs, and ongoing dental work, full-arch implants often cost less over time than continuing to manage the problem.

Permanent Teeth in 24 Hours

At Nuvia, implants are placed one day and your teeth are delivered the next. Those teeth are custom made from zirconia — not a one size fits all plastic set of healing teeth common with standard "teeth in a day" procedures.

Research shows that these temporary teeth are actually designed in a way that makes them easy to break. To make room for the clips that snap the teeth onto the implants, the plastic part of the teeth has to be made very thin. Because that plastic is so thin in those spots, it creates 'weak points' that can snap like a cracker when you chew your food.

You can skip the temporary phase of healing teeth that are prone to breaking and often need to be replaced by opting for Nuvia’s permanent teeth in 24 hours. The first step is to see if you may be a candidate with the 60-second quiz below.
