You’ve lost most of the teeth on one arch, or your dentist has told you the ones you have left aren’t worth saving. You’ve heard about all-on-4 implants. You’ve heard about all-on-6. Both promise a new set of fixed teeth in one day. Both cost a lot. And your consult probably gave you a number for one but not the other, which makes it hard to compare apples to apples. This guide gives you the honest side-by-side: what each option costs, how they handle your bite, which one you actually qualify for based on your bone, and how they hold up over 10 years.
By the end you’ll know whether 4 implants or 6 is right for your case, why the price gap isn’t as big as it sounds once you count add-ons, and what warning signs to look for during the consult when a surgeon steers you toward one or the other.
The Short Answer
All-on-4 uses 4 implants per arch to support a fixed set of teeth. Cost: $18,000 to $30,000 per arch. Great for patients with moderate bone loss and tight budgets.
All-on-6 uses 6 implants per arch. Cost: $22,000 to $38,000 per arch. Better for patients with good bone, heavy bite force, or upper arch cases where extra support pays off.
Neither is universally better. The right pick depends on your bone quality, bite pattern, whether it’s an upper or lower arch, and how much long-term insurance you want against implant failure.
How All-on-4 Actually Works
All-on-4 was developed to give patients with significant bone loss a fixed set of teeth without needing bone grafts. The technique places 2 implants straight up in the front of the jaw where bone is usually best, and 2 implants angled at 30 to 45 degrees in the back. The angled placement avoids the sinus in the upper jaw and the nerve canal in the lower jaw.
All 4 implants are placed in a single surgical visit. A temporary bridge of 10 to 12 teeth is attached the same day, so you walk out with a set of teeth. Four to six months later, once the implants have fused with bone, a final permanent bridge replaces the temporary.
Our team handles both the surgical and restorative sides of these cases through the all-on-4 implants program at Madison Park Dental.
How All-on-6 Actually Works
All-on-6 uses the same principle but adds 2 more implants: one on each side, between the front and back angled implants. The result is more even load distribution, better resistance to fracture of the bridge, and more redundancy if one implant fails 10 or 20 years down the line.
Not every patient qualifies. All-on-6 needs enough bone in the areas where the extra implants go. If your bone has resorbed a lot, you may need bone grafting to make all-on-6 possible, which adds cost and time. If grafting isn’t practical, all-on-4 is the workaround.
Our team uses the same same-day protocol on all-on-6 cases: implants placed, temporary bridge attached, final bridge in 4 to 6 months.

Cost Reality in 2026
The sticker prices vary a lot by geography, surgeon, and material. Here’s the honest range for what’s typically included in each quote:
All-on-4 per arch ($18,000 to $30,000) usually includes:
- 4 implant fixtures
- Any needed extractions
- Same-day temporary bridge
- Final zirconia or acrylic bridge (4 to 6 months later)
- All follow-up visits for the first year
All-on-6 per arch ($22,000 to $38,000) includes the same list plus 2 additional implants.
What’s often not included:
- Bone graft: $500 to $3,000 per site
- Sinus lift: $1,500 to $3,000
- Sedation upgrade beyond IV: $500 to $1,500
- Nightguard for the final bridge: $300 to $600
- Bridge repairs or acrylic replacement in years 5 to 10: $1,000 to $3,500
Ask your surgeon for an all-in written quote before signing. Prices creeping up on the day of surgery is one of the most common complaints in implant reviews.
Bite Force and Chewing Power
Natural teeth generate 150 to 250 pounds of bite force. All-on-4 typically restores 70 to 85 percent of that. All-on-6 restores 85 to 95 percent. The difference matters if you eat a lot of steak, crusty bread, raw vegetables, or if you grind at night.
The distributed load across 6 implants lowers the risk of bridge fracture. All-on-4 bridges have a 5 to 10 percent chance of a small crack or acrylic chip in the first 10 years. All-on-6 bridges cut that closer to 2 to 4 percent.
Bone Requirements for Each Option
The angled implant technique in all-on-4 was designed to work in patients with resorbed bone. If you’ve been missing teeth for years or wearing dentures for a decade, your jawbone has shrunk. All-on-4 avoids the sinuses and nerves by tilting the back implants and often skips the need for bone grafting.
All-on-6 needs more bone volume in the middle regions of the jaw where the extra implants go. If your CT scan shows enough bone across the whole arch, all-on-6 is feasible without grafting. If you have moderate loss in the mid-arch, expect either a bone graft or a recommendation to stay with all-on-4.
Your surgeon will take a 3D cone-beam CT scan (about $200 to $500) to measure exact bone width and height. Do not commit to either option without this scan.
Upper Arch vs Lower Arch: The Big Deciding Factor
The upper jaw (maxilla) is softer bone with less density. It fails implants more often than the lower jaw. If you’re doing an upper arch, most surgeons lean toward all-on-6 for the extra insurance.
The lower jaw is denser and typically holds implants very well. All-on-4 on the lower arch is often the honest choice: strong enough, lower cost, and typically no bone graft needed.
A common combination that comes up often: all-on-6 up top and all-on-4 on the bottom. Total cost about $40,000 to $65,000 for both arches.
How Long Each Option Lasts
Implants themselves are titanium and can last 25+ years. Implant success rates at 10 years, per published long-term studies, sit around 94 to 96 percent for all-on-4 and 96 to 98 percent for all-on-6.
The bridge (the visible teeth) has a shorter timeline. Acrylic-wrapped titanium bridges last 5 to 10 years before the acrylic teeth wear or discolor. Zirconia bridges last 10 to 20 years and don’t yellow. Ask which material your quote covers before comparing prices.
What the Consultation Should Cover
A proper full-arch implant consult should take 60 to 90 minutes and include:
- A 3D cone-beam CT scan of both jaws
- A discussion of both all-on-4 and all-on-6 for your case
- Photos of previous cases the surgeon has done
- A written treatment plan with all-in cost
- A list of what’s included and what could add cost
- An honest answer on whether you need any bone grafting
- Options for financing or in-house payment plans
If a surgeon quotes only one option without explaining why the other doesn’t fit, get a second opinion. Both options have valid use cases and a good surgeon will show you both.
Recovery Timeline
Recovery is very similar for both options. The surgery day is under IV sedation or general anesthesia. You leave with a temporary bridge in place.
- Days 1 to 3: swelling and mild pain, soft food only, ice packs
- Days 4 to 7: swelling drops, back to office work possible
- Weeks 2 to 4: normal daily life, still eating soft to medium foods
- Weeks 4 to 12: normal eating within the limits of the temporary bridge (avoid very hard foods)
- Months 4 to 6: osseointegration complete, final bridge placed
Most patients return to desk work 2 to 4 days after surgery. Physical work waits until day 10.
Are Regular Implants a Better Path for You
If you’re only missing a few teeth (not the whole arch), full-arch implants are overkill. Individual dental implants replacing single missing teeth cost $3,500 to $6,500 each. Our full dental implant cost breakdown walks through the per-tooth math. If you have 6 or fewer missing teeth per arch, several single implants or a smaller implant-supported bridge is usually cheaper and more conservative than an all-on-4 or all-on-6.
Full-arch implants make sense when you’re missing (or about to lose) most or all teeth on an arch, and when saving individual teeth would cost more with less certainty than starting fresh.
Frequently Asked Questions
Which lasts longer, all-on-4 or all-on-6?
All-on-6 has slightly higher implant survival at 10 years (96 to 98 percent versus 94 to 96 percent) and lower bridge fracture risk. Both are excellent long-term solutions. The lifespan difference is real but not dramatic. Where all-on-6 shines is in patients with heavy bite forces or upper-arch cases where the extra support matters more.
Do the implants get placed in one day?
Yes. Both all-on-4 and all-on-6 use a same-day protocol: the implants are placed and a temporary bridge is attached in the same surgical visit. You go home with a set of teeth. The final permanent bridge replaces the temporary 4 to 6 months later once the implants have fully integrated with bone.
Will insurance cover any of the cost?
Some. Most PPO plans have a lifetime implant maximum of $1,000 to $3,000 and cover extractions and sometimes the bridge portion at 50 percent. Realistic expectation: insurance covers 5 to 15 percent of the total cost. Medical insurance rarely covers dental implants except in rare traumatic injury or cancer reconstruction cases.
Can I get financing for full-arch implants?
Yes. Most implant offices offer in-house payment plans and third-party financing through CareCredit, Lending Club, or similar companies. Terms range from 12 to 84 months. Interest-free periods of 6 to 24 months are common if you can pay the full balance in that window. Ask about all financing options before you commit.
What if I don’t have enough bone for either option?
Severe bone loss opens up other options: zygomatic implants (anchored in the cheekbone), pterygoid implants (anchored in the back skull region), or bone grafting before implant placement. These are more complex procedures done by specialized oral surgeons. Cost adds $5,000 to $20,000 and the timeline extends by 6 to 12 months.
How do I clean under the bridge?
A water flosser is the tool of choice. Once daily use of a water flosser under the bridge, plus normal brushing on the visible surfaces, keeps the implants and bridge clean. Special implant-thread floss helps too. Professional cleanings every 4 to 6 months are important to check the tissue around each implant.
Can I remove the bridge to clean it?
Not at home. The bridge is screwed or cemented in place and only your dentist can remove it. You clean it in your mouth like natural teeth. At major service visits (usually every 3 to 5 years), your dentist may unscrew the bridge to clean underneath, replace worn parts, and check the implants.
The Bottom Line
All-on-4 is the honest choice for lower arches, patients with meaningful bone loss, and tighter budgets. All-on-6 is the smarter pick for upper arches, heavy chewers, and cases with plenty of bone. Neither is universally right. A proper 3D CT scan and a surgeon who walks you through both options will give you a clear answer for your specific case.
