If you are missing most or all of your teeth and researching permanent solutions, you have likely come across two terms: All-on-4 and All-on-6 dental implants. Both procedures replace an entire arch of teeth with a fixed, non-removable prosthesis anchored to dental implants — but they differ in the number of implants used, candidacy requirements, and cost. In this guide, the oral surgery team at Precision Oral Surgery breaks down the key differences so you can make an informed decision.
What Are All-on-4 Dental Implants?
The All-on-4 protocol uses four strategically placed titanium implants to support a full arch of prosthetic teeth. Two implants are positioned vertically in the front of the jaw, while the rear two are angled at up to 45 degrees to maximize contact with available bone. This angulation often eliminates the need for bone grafting, even in patients with moderate bone loss.
All-on-4 is one of the most well-researched implant protocols in dentistry, with clinical studies showing success rates above 95 percent over 10 years. At Precision Oral Surgery, All-on-4 full arch restorations start at competitive pricing — among the most competitive prices along the Colorado Front Range.
What Are All-on-6 Dental Implants?
The All-on-6 approach follows the same concept but uses six implants per arch instead of four. The two additional implants provide extra support and distribute biting forces across more points of contact. This can be particularly beneficial for patients who have adequate bone density and want maximum long-term stability, or for those who place heavy demands on their bite.
Because All-on-6 requires more implants and slightly more surgical time, the cost is typically higher than All-on-4 — though many patients find the added investment worthwhile for the extra support.
All-on-4 vs All-on-6: Key Differences
Number of implants: All-on-4 uses four implants per arch; All-on-6 uses six. More implants generally mean wider force distribution.
Bone requirements: All-on-4 was specifically designed for patients with reduced bone volume, thanks to the angled posterior implants. All-on-6 typically requires more available bone, though grafting can sometimes bridge the gap.
Surgical complexity: All-on-6 involves a slightly longer procedure and additional implant sites. Both procedures can often be completed in a single visit with same-day temporary teeth.
Cost: All-on-4 is generally the more affordable option. At Precision Oral Surgery, full arch restorations start at competitive pricing for All-on-4.
Long-term durability: Both options offer excellent longevity. Some prosthodontists prefer All-on-6 for the upper jaw, where bone tends to be softer, while All-on-4 performs exceptionally well in the lower jaw.
Which Option Is Right for You?
The best choice depends on your bone density, overall oral health, budget, and long-term goals. During your consultation at Precision Oral Surgery, our surgeons use 3D cone beam imaging to evaluate your jaw structure and recommend the protocol that will deliver the strongest, most natural-feeling result.
Many patients who have been told they are “not candidates” for dental implants discover that All-on-4’s angled implant approach makes treatment possible without bone grafting. Others with excellent bone density may benefit from the added stability of All-on-6.
