All-on-4 vs. Conventional Implant Prosthesis: What’s the Difference?
by Dr. Davide Romeo, Prosthodontist at Milano Dental Studio | Manhattan, NY
If you’re considering full-mouth dental implants, you’ve likely come across two common options: the All-on-4 treatment concept and conventional implant-supported prostheses. While both aim to restore full arch function and esthetics, they differ significantly in approach, timeline, and cost.
Here at Milano Dental Studio in Manhattan, Dr. Davide Romeo — a prosthodontist with 20+ years of experience in full-arch implant rehabilitation — helps patients choose the best treatment for their needs. Below is a comparison to help you understand the advantages of All-on-4 over conventional methods.
What Is All-on-4?
All-on-4 is a streamlined full-arch solution that uses just four strategically placed dental implants to support a fixed prosthesis. The back implants are angled to maximize available bone, often avoiding bone grafting, and patients typically receive a temporary set of teeth the same day.
Advantages of All-on-4 Over Conventional Implant Prosthesis
1. Fewer Implants Required
All-on-4: Only four implants per arch (occasionally 5–6 for added support).
Conventional: Typically 6–8 implants per arch.
2. No Bone Grafting in Most Cases
All-on-4 uses angled implants to engage denser bone, avoiding sinuses and nerves.
3. Immediate Function (“Teeth in a Day”)
All-on-4: allows patients to receive a fixed temporary prosthesis on the same day as surgery.
Conventional methods: often require a healing period of 3–6 months before loadin
4. Shorter Treatment Timeline
Because All-on-4 typically eliminates grafting and allows immediate loading:
Conventional methods can require multiple surgeries and over a year of treatment.
5. Lower Cost Than Full Implant Rehabilitation
Fewer implants + no grafting + shorter chair time = significant cost savings.
6. Proven Long-Term Success
Dr. Romeo has used All-on-4 for over 20 years, and long-term studies show:
