ALL-ON-4 VS. ALL-ON-6 DENTAL IMPLANTS

All-On-4 vs. All-On-6 Dental Implants: Which Protocol Is Right for You?

If you are missing most or all of your teeth, All-On-4 and All-On-6 dental implants are two of the most reliable ways to replace an entire arch with a fixed, permanent set of teeth. Both protocols use strategically placed implants to anchor a full-arch bridge, but the number of implants, the strength they provide, and the situations where each shines are different enough to matter. At Lake Norman Oral & Facial Surgery in Huntersville (Charlotte metro), Dr. Raymond J. Haigney II, FACS helps patients weigh these options against their own bone anatomy, budget, and long-term goals.

What All-On-4 and All-On-6 Have in Common

Both procedures were developed to replace a full arch of missing or failing teeth without the six to eight implants that traditional full-mouth restorations once required. Implants are surgically placed in the jaw under IV sedation or general anesthesia, and the surgery itself typically takes two to three hours per arch. Because the implants fuse directly to bone through osseointegration, both protocols restore a strong, stable bite and continue to stimulate the jawbone the way a natural tooth root would, preventing the bone loss that plagues long-term denture wearers.

Patients in both groups usually leave surgery the same day with a temporary fixed bridge already in place, and a final, permanent prosthesis is typically ready in about three months once healing is complete. Compared with older methods, which sometimes required six months of healing and extensive bone grafting before a denture could be attached, both All-On-4 and All-On-6 dramatically shorten the timeline to a functional, good-looking smile.

Where the Two Protocols Differ

The name gives away the most obvious difference: All-On-4 anchors the bridge with four implants per arch, while All-On-6 uses six. That difference in implant count changes how force is distributed every time you bite or chew.

Many practices choose one protocol as their default based on training and clinical philosophy. At Lake Norman Oral & Facial Surgery, Dr. Haigney generally recommends All-On-6 when bone quality and quantity allow for it, because the two additional implants spread chewing force across more anchor points. That translates into a more secure, more comfortable bite and a prosthesis that tends to hold up better over decades of use.

The extra implants in All-On-6 also mean more surface area transmitting stimulation into the jawbone. Bone that no longer supports a tooth root begins to resorb, which is why long-term denture wearers often develop a sunken, aged facial appearance once their bone has receded. More implants mean more of the jaw stays mechanically active, helping preserve facial structure along with the bite itself.

All-On-4 remains an excellent option when a patient's bone volume, sinus position, or budget make six implants impractical. The angled placement used in All-On-4 was specifically engineered to make the most of limited bone without grafting, so it is often the more accessible starting point for patients who might otherwise need extensive bone-building surgery first.

How Dr. Haigney Decides Which Protocol Fits

Choosing between All-On-4 and All-On-6 is not a one-size-fits-all decision. During your consultation, Dr. Haigney reviews a 3D cone-beam CT scan of your jaw to evaluate bone height, width, and density at each potential implant site, along with the position of the sinuses and nerves. Patients with strong, ample bone are often good candidates for All-On-6 and its added stability. Patients with more limited bone, or who are managing a tighter treatment budget, may be better served starting with All-On-4.

• Bone volume and density — determines how many implants a given arch can comfortably support
• Bite force and habits — patients who grind their teeth or chew heavily may benefit from the added stability of six implants
• Timeline and budget — All-On-4 can reduce upfront cost and surgical time while still delivering a fixed, permanent result
• Long-term goals — patients planning to keep their prosthesis for decades often lean toward the extra support of All-On-6

Both Are Permanent, Life-Changing Solutions

Whether you and Dr. Haigney choose All-On-4 or All-On-6, both protocols deliver a fixed set of teeth that restores full chewing function, protects the jawbone, and eliminates the slipping and clicking that come with removable dentures. Recovery is measured in months, not years, and the improvement in confidence and quality of life is often immediate the moment the temporary bridge is placed.
