All-on-4 dental implants replace a full arch of teeth using just 4 implants. Learn about costs ($20K–$50K per arch), procedure steps, recovery, and find providers.
All-on-4 is a full-arch tooth replacement technique that uses 4 strategically placed dental implants to support a complete set of fixed teeth. Instead of replacing each tooth individually (which would require 8–14 implants), All-on-4 anchors an entire arch of teeth to just 4 posts.
Developed by Dr. Paulo Maló in the 1990s, All-on-4 has become the gold standard for patients with failing teeth, severe decay, or full dentures who want a permanent, fixed solution.
Key advantage: Two of the four implants are placed at a 45-degree angle in the back of the jaw. This maximizes contact with existing bone and often eliminates the need for bone grafting — saving time, cost, and healing.
Zirconia vs acrylic: The final prosthesis material is the biggest cost variable. Zirconia (ceramic) prostheses cost $15,000–$25,000 per arch but are stronger and more natural-looking. Acrylic prostheses cost $8,000–$15,000 but may need replacement sooner.
Consultation & planning (Week 1) Your specialist takes 3D CT scans to map your jawbone density and plan implant placement. Digital smile design software creates a preview of your final result.
Surgery day (Day of procedure) Under IV sedation, the specialist extracts any remaining teeth, places 4 implants, and attaches a temporary set of fixed teeth. You walk out with a full smile the same day.
Healing period (Months 1–4) The implants fuse with your jawbone through a process called osseointegration. You eat a soft diet for 6–8 weeks while healing. The temporary teeth are fully functional — you can talk, smile, and eat soft foods normally.
Final prosthesis (Month 4–6) Once fully healed, impressions are taken for your permanent prosthesis. The final zirconia or acrylic teeth are fabricated by a dental lab and permanently attached to your implants.
All-on-4 is designed for patients who need to replace all teeth in an arch. If you're missing just 1–3 teeth, individual implants are usually better.
Week 1: Swelling peaks at 48–72 hours, then subsides. Pain is managed with prescribed medication. Soft/liquid diet only.
Weeks 2–6: Gradually introduce soft foods (pasta, eggs, fish). Avoid hard, crunchy, or sticky foods. Swelling fully resolves.
Months 2–4: Return to most normal foods. Continue avoiding extremely hard items (raw carrots, hard candy, ice).
After final prosthesis: Eat normally with no restrictions. Brush and floss as usual. Visit your specialist every 6 months for checkups.
Success rate: All-on-4 has a 95–98% success rate based on long-term clinical studies. With proper care, All-on-4 implants can last 20+ years.
