All-on-4 vs. All-on-6 Dental Implants in Houston: Cost, Candidates, and Which Is Right for You

Short answer: All-on-4 and All-on-6 both replace a full arch of missing or failing teeth with a fixed, non-removable bridge — the number in the name is just how many implants anchor it. All-on-4 is the more common option and commonly runs $20,000–$30,000 per arch in Houston; All-on-6 typically runs higher because of the two extra implants, with your exact number confirmed at your consult. Both are commonly cited in the literature with high long-term survival. Which one fits your case comes down to your bone volume and how your surgeon wants to distribute the bite — something a 3D CBCT scan settles quickly.

All-on-4 vs. All-on-6 at a glance

	All-on-4	All-on-6
Implants per arch	4	6
Typical Houston cost per arch	$20,000–$30,000	Typically runs higher because of the extra implants; confirmed at your consult
Best-fit candidacy	A wide range of bone situations, including reduced bone toward the back of the jaw (posterior implants are often tilted for support)	Often considered when there’s enough bone to spread the load across more anchor points
Bone-graft need	Frequently reduced or avoided by angling the posterior implants into denser bone	Depends on the bone at each of the six sites — evaluated individually, not assumed
10-year implant survival	High long-term survival reported for both — comparative studies commonly cite roughly 94–98% at 10 years	Same general range reported in comparative studies

What is All-on-4?

All-on-4 anchors a full arch of fixed replacement teeth on four implants, usually two toward the front and two angled toward the back. That tilt lets the surgeon reach denser bone without always needing a graft, and it’s often designed to support a same-day temporary set of teeth. We cover the mechanics in more depth in our All-on-4 guide.

What is All-on-6?

All-on-6 uses the same fixed-bridge concept but spreads the load across six implants instead of four. The extra two implants can mean more distributed support across the arch, which some surgeons prefer for patients with enough bone to place them — particularly when a case calls for extra stability or the bite forces are higher than average. It’s still a fixed, non-removable restoration, not a removable denture.

Key differences between All-on-4 and All-on-6

• Implant count. Four vs. six implants per arch is the core distinction — everything else follows from it.
• Bone requirements. All-on-4’s tilted posterior implants are specifically designed to work with less available bone. All-on-6 generally wants more bone volume across more sites, since each implant needs its own solid anchor point.
• Cost. More implants generally means more surgical and material cost — see the Houston ranges below.
• Distribution of support. Some surgeons favor All-on-6 for patients who need the bite force spread across additional points, though four well-placed implants can also carry a full arch successfully.

“All-on-4 and All-on-6 can look nearly identical once the final teeth are in place — the difference is almost entirely about what your bone can support underneath. That’s why we don’t guess; we scan first,” says our clinical team.

Cost in Houston: All-on-4 vs. All-on-6

All-on-4 commonly runs roughly $20,000–$30,000 per arch as a general Houston estimate. All-on-6 typically runs higher than All-on-4 because of the two additional implants and the associated surgical time — we don’t publish a precise All-on-6 range because it varies more by case; your exact number gets confirmed at your consult.

Ranges are general Houston estimates for guidance, not a quote. Both options can involve additional costs for imaging, sedation, extractions, or bone grafting depending on your case, and financing is available — we’ll walk through your itemized numbers together, no pressure, ever.

Which is right for you?

It depends on your bone and your goals — and that’s genuinely an “it depends” with a concrete range to match: most Houston patients land in the $20,000–$30,000 per arch range with All-on-4, with All-on-6 priced higher case by case. In general:

• If your posterior bone is limited, All-on-4’s tilted-implant design is often the more straightforward path, frequently without a bone graft.
• If you have adequate bone across more sites and your surgeon wants extra distributed support, All-on-6 may be recommended.
• Either way, both are full-arch dental implant options built to replace a full denture with something fixed.

How we decide: the 3D CBCT scan

We don’t recommend a number of implants before we’ve actually seen your bone. A 3D CBCT scan maps bone height, width, and density at every potential implant site, along with the position of nerves and sinuses. That scan — reviewed with you at your consultation — is what turns “it depends” into an actual plan, with an itemized price attached.
