All-on-4 Dental Implants: Cost and Results

The All-on-4 concept was developed by Dr. Paulo Maló in Lisbon in the 1990s and has since become the gold standard for full-arch implant rehabilitation. The protocol has over 25 years of published clinical evidence and millions of patients treated worldwide ([ADA](https://www.ada.org/resources/research/science-and-research-institute/oral-health-topics/dental-implants)).

The genius of the system lies in its biomechanical design: by tilting the posterior implants at a 30-45° angle, the surgeon engages the dense cortical bone of the anterior jaw - providing sufficient anchorage for immediate loading (attaching teeth the same day) while avoiding the resorbed posterior bone that would otherwise require expensive, time-consuming bone grafting.

Who Is a Candidate?

• Patients with full or near-full edentulism: Missing all teeth in one or both arches, or wearing dentures.
• Patients with failing dentition: Multiple teeth requiring extraction due to advanced periodontal disease, decay, or fracture.
• Denture wearers: Patients unhappy with removable dentures - loose fit, inability to eat certain foods, embarrassment, adhesive dependence.
• Patients who have been told they don't have enough bone: All-on-4 often works when conventional implants (one implant per tooth) would require extensive bone grafting.

The Procedure: Day by Day

"The All-on-4 protocol has transformed how we approach full-arch rehabilitation. Patients who were told they needed extensive bone grafting and months of waiting can now walk out with functional, beautiful teeth on the same day as surgery."

Pre-Operative Planning

A 3D CBCT (cone beam computed tomography) scan maps the jawbone anatomy in precise detail. Using digital planning software, the surgeon virtually places the four implants in their optimal positions - determining angles, depths, and prosthesis design before the patient enters the operating room.

Surgery Day

1. Anesthesia: IV sedation or general anesthesia. The patient is comfortable and unaware.
2. Extractions: Remaining failing teeth are removed.
3. Implant placement: Four titanium implants are placed per arch - two vertical anteriors, two angled posteriors.
4. Impression and fabrication: An impression is taken. The dental laboratory fabricates a provisional fixed bridge (PMMA acrylic) - often within hours, sometimes using pre-fabricated templates from the digital plan.
5. Provisional bridge attachment: The provisional teeth are screwed onto the implants. The patient leaves with a full, fixed set of teeth.

Total surgery time: 2-3 hours per arch.

Healing Period (4-6 Months)

The provisional bridge remains in place while the implants undergo osseointegration - the biological process by which bone grows directly onto the titanium implant surface, creating a permanent bond ([Mayo Clinic](https://www.mayoclinic.org/tests-procedures/dental-implant-surgery/about/pac-20384842)). During this period, the patient can eat, speak, and smile with the provisional teeth - though a soft-food diet is recommended for the first 2-3 weeks.

Final Prosthesis

After osseointegration is confirmed (via X-ray and torque testing), the provisional bridge is replaced with the definitive prosthesis - typically a full-contour zirconia bridge or a porcelain-fused-to-metal framework. This final prosthesis is designed for maximum aesthetics and durability, with a lifespan of 10-15+ years.

All-on-4 vs. Traditional Implants vs. Dentures

• Implants needed: All-on-4: 4 per arch - Individual: 6-8 per arch - Dentures: 0
• Bone grafting: All-on-4: Rarely needed - Individual: Often required - Dentures: Not applicable
• Same-day teeth: All-on-4: Yes - Individual: Sometimes - Dentures: Yes
• Fixed (non-removable): All-on-4: Yes - Individual: Yes - Dentures: No
• Chewing efficiency: All-on-4: 90-95% of natural - Individual: 90-95% - Dentures: 20-30% ([NHS](https://www.nhs.uk/conditions/dentures/))
• Cost (Wholecares): All-on-4: $5,000-$8,000/arch - Individual: $8,000-$15,000/arch - Dentures: $500-$2,000/arch

At Wholecares partner dental centers, All-on-4 is performed by prosthodontists and implantologists using Nobel Biocare and Straumann implant systems - the same premium brands used globally. All-inclusive packages cover CBCT scan, surgery, provisional bridge, all follow-up appointments, and the final zirconia prosthesis.

"We use only premium implant systems — Nobel Biocare and Straumann — because long-term success depends on implant quality. The 98% ten-year success rate we see comes from combining quality materials with precise digital planning and experienced surgical technique."
