If you're researching full-mouth dental implants, you've almost certainly come across the terms All-on-4 and All-on-6. Both are life-changing solutions for patients dealing with missing, failing, or painful teeth — but they are not the same procedure, and the difference matters. At Ohana Dental Implant Centers, we offer both options at our Grand Junction, Montrose, and Clifton, Colorado locations. Here is an honest breakdown so you can walk into your consultation prepared.
What Is All-on-4?
All-on-4 is a full-arch tooth replacement system that uses four dental implants per jaw to support a complete set of fixed teeth. Two implants are placed vertically in the front of the jaw, while two are angled up to 45 degrees in the back. This angled placement allows the implants to engage denser bone further forward in the jaw, eliminating the need for bone grafting in most cases and making the procedure viable for patients who have already experienced significant bone loss.
At Ohana, All-on-4 arches are fabricated from high-strength zirconia in our on-site Zirkonzahn lab, and most patients receive a full provisional smile the same day as surgery. The final zirconia restoration is delivered once the implants have fully integrated with the bone — typically four to six months later.
All-on-4 at a Glance (Ohana Pricing)
- Implants per arch: 4 (2 vertical + 2 angled at up to 45°)
- Bone grafting needed: Usually not required
- Same-day delivery: Yes — provisional arch placed at surgery
- Expected lifespan: 20+ years for a zirconia restoration
- Starting cost at Ohana: $20,000–$23,000 per arch
- Best for: Patients with moderate-to-severe bone loss, or those seeking a cost-effective full-arch option
What Is All-on-6?
All-on-6 takes the same concept further by using six vertically placed implants per arch. Rather than a single full-arch prosthetic, Ohana's All-on-6 protocol uses three separate zirconia bridges — each supported by two implants — creating a load distribution pattern that more closely mimics natural teeth. The result is exceptional stability, long-term durability, and aesthetics virtually indistinguishable from natural dentition.
Because all six implants are placed vertically rather than angled, All-on-6 generally requires more bone volume. Patients with moderate bone loss may need a bone grafting procedure before implant placement. For patients who qualify, however, All-on-6 is the highest-performance full-arch restoration we offer.
All-on-6 at a Glance (Ohana Pricing)
- Implants per arch: 6 (all vertically placed)
- Bone grafting needed: May be required if bone loss is present
- Same-day delivery: Yes — provisional arch placed at surgery
- Expected lifespan: 25+ years; three-bridge design is highly repairable
- Starting cost at Ohana: $25,000–$30,000 per arch
- Best for: Patients with adequate bone density seeking maximum stability, aesthetics, and longevity
Side-by-Side Comparison
| Factor | All-on-4 | All-on-6 |
|---|---|---|
| Implants per arch | 4 (2 vertical + 2 angled) | 6 (all vertical) |
| Bone graft required? | Rarely | Sometimes |
| Prosthetic design | Single full-arch prosthesis | Three separate zirconia bridges |
| Repairability | Full arch replaced if damaged | One bridge replaced; others unaffected |
| Aesthetics | Excellent | Most natural-looking option |
| Ideal candidate | Bone loss, budget-conscious | Good bone density, maximum longevity |
| Starting cost (Ohana) | $20,000–$23,000 / arch | $25,000–$30,000 / arch |
| Warranty at Ohana | 5-year fixed arch warranty | 5-year fixed arch warranty |
What the Research Shows: A five-year multicenter randomized clinical trial published in Clinical Oral Implants Research (Toia et al., 2025) found no statistically significant difference in marginal bone levels between four- and six-implant full-arch restorations at the five-year mark. The number of implants is only one variable. Placement precision, implant quality, bone health, and surgical experience all play equally important roles in long-term outcomes.
How Ohana Determines the Right Option for You
Every patient who visits Ohana Dental Implant Centers receives a complimentary CBCT cone beam scan — a 3D imaging technology that provides a precise view of your jawbone density, sinus anatomy, and nerve locations. This eliminates guesswork and ensures every treatment plan is built on your actual anatomy, not an assumption. Most patients know before they leave their first appointment exactly which option is the right fit.
Ohana is a dedicated implant and denture practice — not a general dentistry office that offers implants on the side. Our team has advanced training in full-arch implant placement and restoration, with more than 4,000 implants placed and 10,000 dentures delivered. We take on complex cases, including patients who have been told elsewhere that implants were not an option.
Frequently Asked Questions
Can I get All-on-4 or All-on-6 if I already wear dentures?
Yes — and this is one of the most common reasons patients come to see us. Existing dentures do not disqualify you. Our team will evaluate how much bone you have retained and recommend the best path forward. In many cases we can begin treatment the same day as your consultation.
Will I have teeth on the day of my surgery?
In almost all cases, yes. Ohana's on-site Zirkonzahn milling lab allows us to fabricate your provisional teeth the day of surgery. You leave with a functional, beautiful smile. The final zirconia restoration is placed once osseointegration is confirmed — usually four to six months later.
Is All-on-4 or All-on-6 covered by dental insurance?
Most insurance plans classify implants as elective and do not cover the implant posts themselves. However, associated procedures — extractions, bone grafting, and sometimes the crown component — may be partially covered. Ohana files all insurance claims on your behalf and works to maximize every available benefit. We also offer third-party financing with instant approval, often with no credit check required.
How long does the All-on-4 or All-on-6 procedure take?
The surgical appointment typically takes three to five hours depending on the complexity of your case. You'll need someone to drive you home if you choose IV sedation. Most patients return to light activity within one to two days. Full recovery and final restoration delivery occurs over four to six months.
What makes Ohana different from other implant providers in Western Colorado?
Ohana Dental Implant Centers is the only dedicated full-arch implant practice on the Western Slope with an on-site Zirkonzahn milling lab, a certified nurse anesthetist for in-house IV sedation, and a team that focuses exclusively on implant and denture solutions. This specialization — and our 5-year warranty on all fixed arches — reflects the level of commitment we bring to every case.
