What Are Full-Arch Dental Implants?
Full-arch dental implants replace all the teeth on either the upper jaw, the lower jaw, or both — using a small number of dental implants as anchors for a permanent prosthetic bridge. Unlike traditional dentures, which sit on top of the gums and can shift, full-arch implants are surgically fixed in the bone and feel and function like natural teeth.
The procedure is appropriate for patients who:
- Have lost most or all of their teeth on one or both arches
- Have severely failing teeth (advanced gum disease, multiple infections) that are not worth saving individually
- Have been wearing traditional dentures and want a stable, non-removable alternative
- Want a long-term solution rather than ongoing piecemeal dentistry
The result is a full set of teeth — typically 10 to 14 teeth per arch — that you can eat with confidently, speak with clearly, and care for like natural teeth. Modern full-arch implants have success rates above 95% at 10 years when placed and maintained properly.
What Is All-on-4? When It Is the Best Choice
All-on-4 was developed by Portuguese implantologist Paulo Maló in the 1990s and has since become the most widely-performed full-arch implant technique in the world. The name refers to using exactly 4 implants per arch to support a full set of fixed prosthetic teeth.
The four implants are placed strategically: two vertical implants in the front of the jaw where bone is thickest, and two tilted (angled) implants in the back. The angled placement avoids the sinus cavity in the upper jaw and the nerve canal in the lower jaw, which means most patients can have All-on-4 without requiring a bone graft or sinus lift — a major time and cost saving.
All-on-4 is the best choice when:
- You want the lowest-cost full-arch option that still gives a fixed, permanent result
- You have enough bone in the front of the jaw for two vertical implants
- You want to avoid extensive bone grafting
- You want a relatively shorter total treatment timeline (often called “teeth in a day”)
- You are medically fit for surgery with no major contraindications
Same-day function is one of the major advantages of All-on-4. In most cases, we extract any remaining teeth, place the implants, and attach a temporary fixed bridge — all in the same appointment. You go home with teeth. The final, more aesthetic and durable bridge is placed 3–6 months later after the implants have fully integrated with the bone.
At Dentist of Aventura, All-on-4 typically costs $20,000–$30,000 per arch. The price includes the surgery, the four implants, all temporary and final restorations, and follow-up visits during the integration phase.
What Is All-on-6? Added Stability for Specific Cases
All-on-6 uses six implants per arch instead of four. The principle is the same — implants in the bone support a fixed bridge — but the additional two implants give more total support, distribute biting forces more evenly, and provide additional security in case one implant later fails.
All-on-6 is appropriate when:
- You have adequate bone for six implants (or are willing to undergo bone grafting if needed)
- You have a strong bite force or grind your teeth at night (bruxism)
- You want extra long-term redundancy — if one implant ever fails, five remain
- Your upper jaw needs additional anterior-posterior support (the upper jaw has softer bone than the lower)
- Your case involves longer prosthetic spans that benefit from more anchor points
The trade-offs versus All-on-4:
- Higher cost — typically $25,000–$35,000 per arch at our office
- More surgical time and slightly longer recovery
- May require bone grafting if posterior bone volume is limited
In our practice, we recommend All-on-6 more often for the upper arch than the lower arch. The upper jaw has biologically softer bone and the bite forces from the lower jaw act against it, so the additional implants add meaningful long-term stability.
What Is All-on-X? The Modern, Customized Approach
All-on-X is the newest evolution in full-arch implant dentistry. The “X” stands for the variable number of implants — typically 4, 5, 6, or 8 — chosen based on the individual patient’s bone anatomy, bite, and clinical needs.
Rather than applying a fixed protocol (always 4, or always 6), All-on-X uses advanced imaging (CBCT 3D scans), digital surgical planning, and computer-guided surgery to design the optimal implant configuration for each patient.
What makes All-on-X different in practice:
- Pre-surgical digital planning — we map your jaw in 3D and virtually place implants before any surgery
- Computer-guided surgical templates — implants go in the exact pre-planned position with sub-millimeter precision
- Custom prosthetic design — the final teeth are designed from the start, not adapted afterward
- Often involves zirconia prosthetics rather than acrylic, for a more natural look and longer wear
- Same-day teeth in the majority of cases, with immediate fixed temporaries
All-on-X is the right choice when:
- You want the most advanced technology and personalization
- You have specific anatomical considerations (severe bone loss, sinus involvement, unusual bite)
- You value the long-term outcome and aesthetics enough to justify a higher initial cost
- You want zirconia (rather than acrylic) prosthetic teeth from the start
Cost at our office typically ranges $25,000–$40,000+ per arch depending on the number of implants, materials, and any preparatory procedures.
For complex cases — patients who have been told they “aren’t candidates” for implants elsewhere — All-on-X is often the technique that makes treatment possible. Dr. Elaine Perez-Gutierrez, DMD, performs All-on-X surgery at our Aventura office with full 3D planning.

Both arches done at the same time (full-mouth reconstruction) typically come with a 10–15% combined discount.
Who Is the Best Candidate? Who Should Not Get Full-Arch Implants?
Most adults who have lost most of their teeth — or whose remaining teeth are failing — are candidates for some form of full-arch implant treatment. The differences between All-on-4, All-on-6, and All-on-X are about which approach fits best, not whether implants are possible at all.
Strong candidates:
- Adults aged 25 and older with mature jawbone
- Patients in generally good health
- Patients willing to follow oral hygiene and follow-up instructions
- Patients with a stable medical situation (controlled diabetes is fine; uncontrolled is risky)
- Patients who don’t smoke heavily (smoking reduces success rates but doesn’t eliminate them)
Patients who need extra evaluation:
- Heavy smokers — implant failure rates are 2–3x higher; quitting before surgery is strongly recommended
- Patients on bisphosphonate medications (some osteoporosis drugs) — increases risk of osteonecrosis of the jaw
- Patients undergoing chemotherapy or recent radiation therapy to the jaw
- Patients with uncontrolled diabetes or autoimmune disease
- Patients with severe bone loss — may need extensive grafting first

What to Expect During the Procedure at Dentist of Aventura
Here is the typical sequence for an All-on-4 or All-on-6 case at our office:
Visit 1 — Consultation (60–90 minutes). You meet with Dr. Perez-Gutierrez. We take a CBCT 3D scan, traditional X-rays, and digital photos. We review your medical history and discuss goals. You receive a written treatment plan with all costs.
Visit 2 — Surgical day (4–5 hours total). Local anesthesia (with optional IV sedation) is administered. Any remaining teeth in the arch are extracted. The implants are placed. A temporary fixed bridge is attached the same day. You go home with teeth.
Visit 3–6 — Integration follow-ups. Brief check-up appointments every 4–6 weeks to confirm healing is on track.
Visit 7 — Final impressions (60 minutes). After 3–6 months of healing, we take impressions for the final, custom-fabricated bridge.
Visit 8 — Final delivery (90 minutes). The permanent bridge is attached.
Visit 9 — One-year follow-up. We check the implants, the bridge, your bite, and your oral hygiene.
Throughout the process, our team is available by phone for any questions or concerns.
Frequently Asked Questions
Q1. Is the All-on-4 surgery painful?
Most patients describe the day of surgery as comfortable. We use local anesthesia, with optional IV sedation for anxious patients. Some swelling and tenderness for 3–7 days afterward is normal. Most patients return to work and normal activities within 2–3 days.
Q2. How long do All-on-4 implants last?
When properly cared for, the implants themselves typically last 20+ years and often a lifetime. The prosthetic bridge (the visible teeth) usually needs replacement every 10–15 years due to normal wear, similar to natural tooth restorations.
Q3. Can All-on-4 be done in a single day?
Yes. The surgery itself is a single day, and you go home that same day with a temporary fixed bridge — teeth you can use to eat softer foods. The final, custom-made bridge is placed 3–6 months later after the implants have fully integrated.
Q4. Will insurance cover All-on-4 or All-on-6?
Most dental insurance plans provide partial coverage, typically toward the extractions and a portion of the prosthetic. Annual maximums ($1,500–$2,500) limit what insurance can cover in a single year. We help maximize benefits across two calendar years when possible.
Q5. Can I eat normally after All-on-4?
After the initial 1–2 week soft-food healing period, patients can eat most normal foods with the temporary bridge. Once the final bridge is placed at 3–6 months, you can eat virtually anything — steak, apples, corn on the cob — as you would with natural teeth.
Q6. What is the difference between All-on-4 and All-on-X exactly?
All-on-4 always uses 4 implants per arch in a standardized configuration. All-on-X uses a customized number of implants (typically 4–8) chosen based on your specific bone and bite, with full 3D digital surgical planning. All-on-X is more personalized but also higher cost.
Q7. How do I know if I have enough bone for implants?
The only reliable way is a 3D CBCT scan, which we include in your free consultation. If bone volume is limited, we may recommend a bone graft, a sinus lift, or All-on-X with a customized implant plan that works with your existing bone.
