All-on-4 vs All-on-6: Which Is Right for You?

The idea behind both

When all teeth in an upper or lower arch are lost (or unsalvageable), a full denture is one option — but it moves, shifts, and affects chewing. Implant-supported full arches replace all teeth with a fixed bridge anchored to 4 or 6 implants in the jaw.

All-on-4

• 4 implants per arch: 2 straight in the front, 2 tilted backwards toward the rear
• The tilting gets around limited bone height at the back of the jaw
• Often allows same-day teeth (temporary bridge placed immediately on surgery day)
• Proven by 20+ years of clinical data (Malo protocol, 1998)

Best for: patients with moderate-to-severe bone loss, budget constraints, or who want faster treatment.

All-on-6

• 6 implants per arch: more anchors, more stability
• Better for heavier bite force patients (grinders, muscular jaws)
• More forgiving if one implant ever has a complication — 5 remain functional
• Slightly better long-term bone preservation across the arch

Best for: patients with adequate bone height, heavy occlusal forces, longer-term outlook, or anyone doing both arches and wanting maximum stability.

Cost difference in Dubai

• All-on-4 per jaw: AED 55,000–90,000
• All-on-6 per jaw: AED 75,000–120,000
• Both jaws (dual full arch): 1.7–1.9× single-jaw pricing

Same-day teeth (immediate load)

Both protocols can support immediate loading — temporary fixed teeth placed within 24 hours of implant surgery. Final zirconia prosthesis follows 3–4 months later after bone integration.

Who qualifies for same-day teeth:

• Adequate primary stability of implants (measurable at surgery)
• No severe medical conditions (uncontrolled diabetes, immunosuppression)
• Not a heavy smoker
• Willing to eat soft foods for the initial healing period

What the final prosthesis is made of

• Acrylic over titanium frame: lighter, more affordable, slightly more wear — good for the temporary bridge
• Full zirconia (monolithic or layered): premium, highly durable, aesthetic — the final choice for most patients

Aftercare

Full-arch prostheses last 15–25 years with:

• Professional cleaning every 4 months
• Water flosser daily underneath the bridge
• Nightguard to protect against grinding forces
• Annual x-rays to verify bone stability

The fixed bridge is removable only by the dentist for periodic cleaning — not by the patient. Daily cleaning is done underneath with a water flosser and interdental brushes.

The decision matrix

| Factor | All-on-4 | All-on-6 | |---|---|---| | Budget | ✓ | | | Faster completion | ✓ | | | Heavy grinder | | ✓ | | Both arches long-term | | ✓ | | Severe bone loss | ✓ | | | Bigger safety margin | | ✓ |

Neither is universally better. The right choice depends on your bone volume, bite force, and long-term priorities.

Practical decision guide

Implant planning is a medical and engineering decision. The useful question is not only whether an implant can be placed, but whether the bone, gum, bite, medical history, hygiene routine, and restoration design make it likely to stay healthy.

Check this first

• CBCT bone volume, gum thickness, sinus or nerve position, smoking/vaping history, diabetes control, and periodontal status.
• Whether the missing-tooth space needs grafting, sinus lift, temporary teeth, or staged treatment.
• How the final crown, bridge, denture, or full-arch restoration will be cleaned and maintained.

When to book sooner

• There is swelling, pus, implant mobility, persistent bleeding, or a bad taste around an implant.
• A recent extraction site is planned for an implant but no grafting or bone-preservation discussion happened.
• You have uncontrolled diabetes, active gum disease, heavy smoking, or bisphosphonate/osteoporosis medication history.

Topic-specific notes

• For implant treatment, ask how bone, gum thickness, bite forces, smoking, diabetes control, and cleaning access affect the plan. A technically placed implant still fails if the long-term maintenance plan is weak.

Questions to ask at the appointment

• Do I need a CBCT scan, graft, sinus lift, or soft-tissue graft before implant placement?
• Which implant system is being used, and can replacement parts be sourced long term?
• How often should this implant be professionally cleaned, and what tools should I use at home?

Dubai patient note

Dubai implant quotes vary because they may or may not include CBCT, surgical guide, grafting, abutment, crown, temporary tooth, sedation, and follow-up. Compare itemised plans rather than headline implant prices.
